Where to Find Britain’s Temperate Rainforests
Six woodland visits that change the way we look at trees, from the ravines of North Wales to the shores of Argyll—and the extraordinary life growing quietly on their branches.
At Coed Felenrhyd, we make very poor progress. There is a path to follow, a wooded valley to explore and the perfectly reasonable prospect of getting somewhere, but an oak beside the route has complicated matters. Its bark is scarcely the outermost surface any more. Moss occupies the creases; fern fronds stand away from the trunk; smaller growths require us to move closer before we can distinguish their shapes. We have come to look at trees and promptly become absorbed in what is growing on them. This abundance is characteristic of the woodland here, where the sheltered valley and humid Atlantic climate support a remarkable collection of mosses, liverworts and lichens.
From a distance, much of this registers as green. At close quarters, green becomes an inadequate description. There are cushions, threads, branching stems and surfaces that look almost painted onto the bark. Identifying everything is beyond a casual visit; noticing that these are different living things is an excellent beginning. We crouch at the edge of the path, leaving the growth undisturbed, and reconsider how much ground we actually need to cover.
Britain’s rainforest asks for this adjustment of scale. The trees may be familiar oaks and birches, yet the community they support belongs to a habitat shaped by persistent moisture and the moderating influence of the ocean. Its character is often most apparent on a branch, a rock or the sheltered side of a ravine, rather than in an enormous view.
Our six visits follow that story through Wales, Devon, Somerset, Cumbria and western Scotland. They include established rainforest, recovering woodland and its closely related southern Atlantic counterparts. Each offers something different to understand. A successful day need not end with a summit, a waterfall or an impressive distance recorded on a watch. Sometimes we have spent a substantial part of it looking at one tree, and have very little reason to apologise.

What makes a British woodland a rainforest?
Rainfall matters, but the conditions between showers matter too. Temperate rainforest develops where a relatively mild climate, high humidity and dependable moisture allow specialised communities to flourish. The wettest examples avoid a significant summer moisture deficit. A wood that looks luxuriant after a November downpour is not necessarily rainforest; nor does every rainforest announce itself with a spectacular waterfall.
We begin by separating things that are easily bundled together. Mosses and liverworts are small, non-flowering plants. Ferns are plants too, but lichens are partnerships involving a fungus and a photosynthetic partner—an alga, a cyanobacterium, or sometimes both. Calling everything on a trunk “moss” is rather like describing every bird on a lake as a duck: understandable at first, increasingly unsatisfactory as we look.
There is also an important geographical distinction. Specialists separate the wettest temperate rainforests from southern oceanic woodlands, where summers are warmer and drier but the lichens and other woodland communities can still be internationally important. Our southern stops belong to this wider Atlantic woodland story. We retain that distinction rather than insisting that an Exmoor oakwood and an Argyll peninsula are ecologically identical.
When to visit—and how much walking to plan
Spring brings woodland flowers and fresh leaves; autumn makes the branching structure easier to read as the canopy changes and falls. Winter rewards a different sort of attention. With less foliage overhead, the shapes of trunks and branches become more conspicuous, and at places such as Taynish the lichens remain a significant part of the woodland’s colour. There is no single season in which the habitat is switched on.
For a first visit, we favour a manageable route with time to stop over an ambitious circuit completed at speed. Take a waterproof, suitable footwear, a map and enough daylight for the return. A small hand lens is an enjoyable addition, although simply moving closer—without stepping onto delicate growth—already changes the experience.
The word rainforest is not an instruction to go out in dangerous weather. Check the landowner’s current notices, especially after storms or prolonged rain, and be prepared to shorten the walk. Access varies considerably between these places: a well-surfaced woodland trail, a steep gorge path and a rocky loop are different propositions, even when their photographs look equally inviting.
1. Coed Felenrhyd & Llennyrch, North Wales
Let the smaller things interrupt the walk
We keep the first part of the walk deliberately unhurried. Above the Vale of Ffestiniog, the woodland occupies a landscape of slopes, water and the gorge of the Afon Prysor. Oaks are prominent, but this is a community of trees rather than an oak collection: birch and rowan accompany them, with other native species where conditions allow. The variety continues at much smaller scales on the trunks and rocks.
A hand lens makes a useful change to our usual woodland equipment. Instead of raising binoculars towards something distant, we bring our attention down to the surface immediately beside us. The distinction between a soft-looking cushion and a much finer, branching growth becomes part of the pleasure. We leave precise identifications to a guide where necessary. Recognising that a boulder holds several different kinds of life is more rewarding than confidently giving all of them the wrong name.
The woodland also complicates the attractive idea that conservation consists of leaving everything alone. Its interpretation trail explains why restoring areas planted with conifers requires care. Removing a dense canopy abruptly can expose surviving woodland communities to drying conditions; gradual work helps retain shelter while the wood changes. Once we understand that, the less picturesque parts of a restoration site become worth examining too. They show the practical difficulty of improving a habitat without damaging what has survived.
This is a particularly good visit for anyone who enjoys detail and is comfortable with uneven ground. The lower approach does not describe the whole walk: routes become steep, with rough surfaces and steps. There is no on-site car park, and the small roadside parking provision is genuinely small. We arrange the approach before setting off and allow the terrain to determine the distance. The attraction here is close observation; there is no need to turn it into an endurance test.
Plan your Coed Felenrhyd & Llennyrch visit
Coed Cadw / Woodland Trust
For access and an independent visit
Start with the landowner’s directions and terrain information. This is the most useful source for choosing an entrance and understanding the parking limitations. Choose a route that suits the whole party; the relatively easier beginning should not be mistaken for a level circuit.
Discovering Britain
For a self-guided walk with substance
Its interpretive trail connects the woodland’s ecology with its working history and restoration. Choose this when you want more from the walk than a route line, and read the stops before leaving reliable reception. It is a self-guided resource, not a booked guide or an assurance about current path conditions.
2. Fingle Woods, Devon
A woodland worth visiting before the restoration is finished
At Fingle, we begin at river level. Choosing the Clifford Bridge approach puts the Teign and the lower woodland at the centre of the outing; beginning at one of the higher entrances makes the valley slopes a much larger part of the day. With an extensive network of paths spread through the woods, the name on the destination is less useful than knowing which entrance we have selected.
The important thing to bring here is an interest in a woodland that is changing. Fingle contains surviving ancient woodland habitat alongside areas altered by commercial conifer planting. The National Trust and Woodland Trust bought the site together in 2013, and the National Trust describes a restoration extending over more than two centuries. We are therefore unlikely to see it declared finished during a convenient return visit next spring.
That timescale makes the details more interesting. We look at the different tree cover, the surviving broadleaves and the relationship between the wooded slopes and the river. The question becomes what can be retained, encouraged and connected. A plantation does not erase the history of the ground beneath it, but restoring an ancient woodland community involves much more than replacing one set of trees with another. The remaining habitat is part of the starting material, not something to clear away while preparing a tidier new beginning.
Fingle suits a reader who wants to understand how recovery happens, as well as enjoy a Devon river valley. Those expecting an uninterrupted succession of twisted old oaks should adjust that expectation: variety, including the evidence of past planting, is central to the visit. We keep the riverside walk as the basis of our route and add height only deliberately. The high-level alternatives offer a different perspective, but a rainforest outing does not become more authentic merely because we finish it breathless.
Plan your Fingle Woods visit
Woodland Trust
For choosing the right entrance
Its visitor guide distinguishes the lower Clifford Bridge access from higher approaches, including the Sawmill Shed and Wooston area. Choose this first when planning the walking rather than simply locating the woods. The full path network is extensive; select a manageable section instead of treating it as one recommended circuit.
National Trust
For understanding the restoration
The Trust’s account explains the joint purchase, surviving habitat and long-term ambitions, alongside the wider Fingle Bridge setting. Choose it as the companion to your route information. The two organisations manage the project together: these are complementary ways to plan and understand the visit, not competing tour operators.
3. Horner Wood, Somerset
Read the shape of the tree before calling it untouched
At Horner, an old packhorse bridge makes an appealing reason to stop, but we spend as much attention on the trees around the valley. The ancient oaks include pollards, their shapes carrying evidence of repeated cutting. Elsewhere in the wood stands the General, an oak the National Trust describes as more than 500 years old. Age is impressive here; the history of how a tree reached that age is often more revealing.
Pollarding involved cutting branches above the reach of grazing animals, allowing useful growth to return while livestock occupied the ground below. We look up at the branching forms with that work in mind. What initially appears to be an extravagantly irregular tree can also be evidence of a practical relationship between wood, animals and people. Horner’s old wood-pasture character belongs to this history. The place becomes less easily described as untouched, and considerably more interesting.
The natural history is equally particular. Plantlife identifies Horner as the only known global location for the rare comma lichen Arthonia thoriana. We do not need to find it—or be directed to a vulnerable tree—to appreciate what that means. A woodland can hold something of extraordinary importance that most visitors will never notice. Its survival depends on the right trees and conditions, including the future of lichens associated with ash as ash dieback changes these woods.
Horner is our southern Atlantic oakwood stop, valued for its own communities rather than pressed into the image of a Scottish rainforest. We follow Horner Water before deciding whether to climb. The distinction matters: the National Park’s longer Explorer route includes a substantial ascent and gradients reaching one in four, while a shorter Stroll offers a gentler introduction to the lower valley. A modest walk with time among the old trees can be the more satisfying choice.
Plan your Horner Wood visit
National Trust
For the wood and its facilities
Use the official Horner information for parking, facilities and the wider Holnicote Estate. Choose this as the practical starting point for an independent visit. Check the current arrangements for refreshments and remember that accessible facilities at the entrance do not make every woodland path accessible.
Exmoor National Park
For choosing a walk that fits
Compare the Horner Woods Explorer with the shorter Exmoor Stroll. The Explorer’s ascent is significant, despite its gentle riverside beginning. Choose the shorter option for slower observation or a less demanding outing; choose the longer one because you want the climb, not because you assume more miles must mean more rainforest.
4. Borrowdale, Cumbria
Give the woods the day usually reserved for the fells
We leave Great Wood’s car park without making a summit the objective. In the Lake District this can feel like an omission, as though a proper outing requires us eventually to emerge above the trees. Great Wood provides a useful correction. It is one of the practical starting points for exploring Borrowdale’s rainforest, close enough to familiar visitor routes that the habitat can be overlooked precisely because it is so easy to pass.
Inside the woodland, our attention moves between the branching canopy and the rougher surfaces below it. Old trunks, moss-covered rocks and decaying wood are part of the interest, not obstructions to the view. The oakwoods support specialised lichens and bryophytes—mosses and liverworts—and their significance lies in that living detail as much as in the impression of a green valley from a distance.
We resist the urge to make every fallen limb a subject to move, tidy or step upon. Decaying wood provides habitat and helps sustain the woodland’s processes; a tree’s usefulness does not end when it stops standing. Looking closely at it is a different pleasure from admiring a veteran tree, but it belongs to the same visit. There is no reason to reserve our attention exclusively for the parts that still make good silhouettes.
Borrowdale’s National Nature Reserve was declared in 2024, initially covering a 721-hectare network. That designation recognises a landscape of separate woods and working countryside, rather than a single uniformly enclosed forest. Its future involves reconnecting habitat and working with farmers and other land managers. We come away from the woodland route with a more useful question than how far up the valley we have walked: where will the next generation of these trees be able to grow?
Plan your Borrowdale visit
National Trust
For an independent woodland day
Begin with its rainforest reserve information and choose a specific starting point, such as Great Wood, rather than treating the entire valley as one walk. Match the route to your mobility and available daylight. This is an excellent option for giving the woods a dedicated visit instead of squeezing them between other attractions.
National Trust guided events
For help noticing the smaller life
Look for the next specifically advertised rainforest walk in the Borrowdale events programme. A suitable guided session can add considerably to what we recognise on bark and rock. Check the actual date, route and booking requirements; these are scheduled events, not a daily guiding service.
5. Taynish, Argyll
Follow the woodland far enough to reach the sea
At Taynish, we keep walking when the trees begin to open out. On this peninsula, oakwood gives way to a mixture of grassland, heath, saltmarsh and shoreline. The change is part of the attraction. A visit confined to the densest-looking stretch of trees would miss much of what makes the reserve distinctive: woodland belongs here beside other habitats, rather than occupying every available inch.
Our route takes the mill and shore seriously as destinations, not merely as places to pause before a more strenuous walk. Kilmartin Museum’s regional trail includes Taynish’s human history, helping place the woodland within the surrounding landscape of settlement and work. We stop at the mill remains with that context in mind. The apparent seclusion of a place does not tell us how busy it was in an earlier century.
Back among the trees, the spaces between them deserve attention too. NatureScot manages a balance between woodland regeneration and open glades, controlling deer to help young trees establish while using cattle grazing to retain valuable open habitat. That is a more demanding task than simply deciding that more trees must always be better. The meadow and the young oak can both matter; they do not necessarily need the same treatment.
For walking, Taynish offers a particularly useful choice. The five-kilometre Woodland Trail is described as mostly level and well surfaced. The shorter route to the mill and shore is barrier-free but includes a slope; the three-kilometre Barr Mòr trail is a separate, strenuous option with steep climbing. We stay with the woodland and shore because that is the encounter we have come for. Taking the less demanding route leaves more attention for the place itself.
Plan your Taynish visit
NatureScot
For selecting the appropriate trail
Compare the Woodland Trail, mill approach and Barr Mòr route before arriving. For visitors considering the mill path, NatureScot records a 400-metre, wide, barrier-free approach with a one-in-twelve slope at the end. Check that detail against individual access needs rather than assuming “barrier-free” means completely flat.
Kilmartin Museum
For the wider human story
Its self-guided regional trail includes Taynish and provides a way to connect the reserve with the surrounding area’s history. Choose this as a companion to the NatureScot route information, particularly during a longer Argyll stay. It is not an on-site rainforest tour or a requirement to buy museum admission to enter the reserve.
6. Ariundle Oakwood, Lochaber
The rainforest that helped feed a furnace
At Ariundle, the clue we are looking for is a level patch of ground. Among the trees are surviving charcoal platforms, traces of work that can be less conspicuous than the moss around them. Once we know what they represent, the wood acquires a different history. Its value was once measured partly in fuel, and that use helped shape the trees we have come to admire.
During the eighteenth and nineteenth centuries, the oaks were coppiced on a roughly twenty-year cycle. Cut close to the ground, they regrew to supply further harvests of wood for charcoal, used by the Bonawe iron furnace and the lead-mining industry in Strontian Glen. We look at the stems with those repeated cuts in mind. An old woodland need not consist of trees that were allowed to grow uninterrupted.
The dominant sessile oaks suit the acidic soils over granite, while other native trees add to the woodland community. Mosses, liverworts and lichens occupy trunks, branches and boulders. Rather than making the industrial history an unfortunate preface to the beautiful part, we carry it through the walk. The living wood and the evidence of its use occupy the same ground.
The marked Forestry and Land Scotland circuit is about four and a half kilometres, graded moderate, with uneven surfaces, some short steep sections and boardwalk. Its suggested walking time of an hour and a half is a useful baseline, though our stops require a less ambitious interpretation of the clock. We choose Ariundle for this combination of close natural history and a readable working past. Settle practical needs in Strontian before coming up the glen; the nearest public toilets are in the village, not waiting halfway around the woodland.
Plan your Ariundle visit
Forestry and Land Scotland
For the marked circuit
Its Ariundle Trail gives a clear basis for a first outing: a 4.5-kilometre, moderate route with detailed surface information. Choose this for a defined circuit, allowing extra time for observation. Gravel, muddy or rocky stretches and short climbs mean it should not be treated as a uniformly easy path.
NatureScot
For the reserve’s woodland and river paths
The reserve guide explains the wider track and the smaller woodland and riverside trails, which can be combined into a different walk of around five kilometres. Choose this for more context and route choice. Distinguish it from the Forestry and Land Scotland circuit when planning distance and terrain.
What it takes to keep a rainforest alive
After a day among old trees, we start looking for young ones. A woodland can be beautiful now and still have a problem with what comes next. Where browsing pressure prevents seedlings and saplings from developing, the existing canopy does not automatically have a replacement. The work is to retain the habitat we value while making room for its successors. Deer management is consequently part of woodland conservation, not a subject separate from it.
Yet removing every grazing animal is not a universal answer. At Taynish, the balance includes cattle maintaining open ground while deer pressure is controlled to allow regeneration. Some valuable communities need light and space as well as shelter. We have to judge the particular habitat rather than carry one appealing rule from wood to wood.
Other pressures are less subtle. Invasive rhododendron can crowd out native vegetation, while air pollution threatens sensitive communities. Climate change and tree disease add difficulties that cannot be solved by making a woodland look greener in a photograph. Clearing invasive growth, safeguarding surviving trees and maintaining suitable conditions all belong to the less immediately visible work behind the visit.
Continuity is the part most easily overlooked. Some specialist lichens and bryophytes colonise slowly and depend on very particular conditions. A new planting may be valuable, but it cannot immediately substitute for a long-established woodland community. Protecting the surviving habitat and allowing recovery around it are connected tasks; the new trees do not cancel the importance of the old wood.
For us as visitors, a useful response begins with restraint. We leave moss on its rock, fallen wood where it lies and unusual growth attached to its tree. Photographs do not require rearranging the foreground. We use established routes, follow local notices and support the organisations doing the continuing work. The most meaningful souvenir is often a better question to ask on the next walk: what is growing here, what does it need, and will those conditions still exist when this tree is gone?
Countrylook / Beyond Britain
Three more rainforest encounters
01 / IRELAND
Killarney National Park
For another chapter of the Atlantic woodland story
Killarney is a useful next step because it deepens the encounter rather than simply increasing the scale. Its native oakwoods occupy a landscape that also includes remarkable yew woodland. Around Muckross, we can explore the relationships between woodland, rock and water without turning the day into a mountain expedition.
Our starting choice: The two-kilometre Mossy Woods circuit from Muckross House. Its short distance needs to be read alongside the official moderate grading and rough, sometimes boggy ground. Choose it for an unhurried woodland visit, using the National Parks Ireland route information rather than assuming that a short walk must be an easy one.
02 / WASHINGTON, USA
Hoh Rain Forest, Olympic National Park
For a change of scale
Here the comparison becomes expansive: large conifers, including Sitka spruce and western hemlock, share the forest with moss-laden maples. The trees are different, but looking for the life supported on their surfaces feels familiar after a British rainforest walk. The National Park Service’s interpretation helps explain that abundance without reducing the visit to a competition between enormous trunks.
Our starting choice: The Hall of Mosses, a short loop of around 0.8 miles. Allow time to stop and check current road, trail and visitor-centre information before travelling. Access to the area and the opening of its facilities are separate matters.
03 / TASMANIA, AUSTRALIA
Mount Field National Park
For rainforest within a varied forest walk
The Russell Falls walk passes through a mixture of wet forest and cool-temperate rainforest, with tree ferns and rainforest species alongside towering swamp gums. We keep that mixture in mind: the immense eucalypts and the rainforest community are parts of the experience, not interchangeable labels for every tree. The falls provide a destination, but the approach deserves a substantial share of the visit.
Our starting choice: The 1.4-kilometre return Russell Falls track. The official guide describes it as suitable for wheelchair users with assistance. A parks pass is required; check current alerts and access information before setting out.

Britain’s rainforests, in ten discoveries
Swipe or scroll through the cards to explore all ten facts.
01 / 10
A rainforest need not be tropical
Temperate rainforests grow in cooler regions than their tropical counterparts. Britain’s examples belong to climates where oceanic influence, moisture and relatively mild conditions make a distinctive woodland community possible.
02 / 10
The most revealing life may be on the trees
Mosses, liverworts, lichens and ferns help distinguish Atlantic woodland communities. The tree species themselves can be familiar; what grows on and around them often tells us more about the habitat.
03 / 10
A lichen is a living partnership
A lichen combines a fungus with a photosynthetic partner, usually an alga and sometimes a cyanobacterium. Yeasts and other microorganisms can also be involved. It is more complicated than a small plant attached to bark.
04 / 10
Some fern leaves are scarcely thicker than a cell
Filmy ferns typically have leaf blades only one cell thick. Their delicate structure helps explain both their almost transparent appearance and their close relationship with humid, sheltered habitats.
05 / 10
Tree lungwort changes colour when wet
The upper surface of tree lungwort can appear greenish-brown when dry and become conspicuously bright green when wet. Moisture changes what we see, even before we begin considering differences between species.
06 / 10
Ancient woodland does not mean every tree is ancient
The term describes continuity of woodland on a site, not the age of every individual tree. Young growth, mature trees, old trees and deadwood can all belong within an ancient wood.
07 / 10
A tree’s shape can preserve a working history
Coppicing and pollarding encouraged repeated supplies of useful wood. Multiple stems or distinctive branching forms can therefore be clues to past management, rather than simply picturesque irregularities.
08 / 10
Deadwood remains part of the living forest
Decaying timber supports fungi and invertebrates and participates in nutrient cycling. Leaving it in place can be an important conservation choice, even when it looks less orderly than a cleared woodland floor.
09 / 10
A gap between trees can be valuable habitat
At Taynish, maintaining woodland glades is an explicit conservation objective. Some communities benefit from sheltered, relatively open conditions, so covering every clearing with trees would not necessarily improve the reserve.
10 / 10
A woodland’s importance can fit on a patch of bark
Plantlife identifies Horner Wood as the only known global location for the rare comma lichen Arthonia thoriana. Some of the most consequential reasons to protect a landscape are almost invisible in its most impressive photograph.
