The Diepwalle Forest is the crown jewel of the Knysna forest system — a cathedral of ancient indigenous trees, filtered green light, and the profound silence of one of the oldest and most biodiverse forests in South Africa. The Diepwalle Elephant Trails are a network of day hiking routes through this extraordinary forest, named for the legendary Knysna elephants that once roamed here in their hundreds and whose last survivors still haunt these ancient trees. Here's everything you need to plan your Diepwalle forest hiking adventure.
Where Is Diepwalle?
The Diepwalle Forest Station is situated approximately 20 km north-east of Knysna on the R339 in the Western Cape Garden Route. Diepwalle — meaning "deep walls" in Afrikaans, a reference to the dense forest that surrounds it — is the access point for the finest hiking in the Knysna forest system and is managed by SANParks as part of the Garden Route National Park.
The Knysna forest is the largest indigenous forest in South Africa — a remnant of the great Afromontane forest that once covered much of the Garden Route. Centuries of timber harvesting reduced the forest to a fraction of its original extent, but what remains is extraordinary: ancient Outeniqua yellowwood trees reaching 40 m, dense understorey of tree ferns and wild orchids, and a biodiversity that is remarkable for a temperate forest.
The Knysna Elephants: A Story of Loss and Hope
No guide to Diepwalle is complete without the story of the Knysna elephants. These forest elephants were once widespread throughout the Garden Route forests, with populations numbering in the hundreds. Hunting, habitat loss, and human encroachment reduced the population catastrophically over the 19th and 20th centuries.
By the late 20th century, the Knysna elephant population had been reduced to a single individual — a lone cow who became one of the most famous animals in South Africa. For decades, she was believed to be the last of her kind, a solitary survivor of a population that had once defined the Garden Route forest.
In recent years, evidence has emerged of additional elephants in the Knysna forest — camera trap images and tracks suggesting that the population may be slightly larger than previously believed. The Knysna elephants remain one of the great conservation mysteries of South Africa — elusive, rarely seen, and deeply symbolic of what has been lost and what might yet be saved.
Walking the Diepwalle trails, you are walking in the forest that these elephants call home. You are unlikely to see one — but the knowledge that they are here, somewhere in the ancient trees around you, transforms the experience.
The Diepwalle Elephant Trails: Overview
The Diepwalle trail network consists of three colour-coded circular routes of varying length, all starting and ending at the Diepwalle Forest Station:
- Elephant Trail (Red Route): Approximately 18 km; 5–6 hours; the longest and most rewarding route; traverses the finest sections of the Diepwalle forest including the Giant Yellowwood trees
- Arboretum Trail (Blue Route): Approximately 7.5 km; 2–3 hours; a shorter route through the forest with excellent tree diversity; ideal for families and less experienced hikers
- Terblans Trail (Yellow Route): Approximately 9 km; 3–4 hours; a moderate route through beautiful forest terrain with good birding opportunities
All three routes are well-marked and maintained by SANParks. The Elephant Trail (Red Route) is the recommended route for hikers who want the full Diepwalle experience.
The Elephant Trail (Red Route): What to Expect
The Forest Character
The Diepwalle forest is unlike any other hiking environment in South Africa. There are no mountain passes, no sea cliffs, no dramatic viewpoints. What there is instead is something rarer and more subtle: the extraordinary atmosphere of an ancient, intact indigenous forest.
The canopy closes overhead within minutes of leaving the forest station, and the light changes immediately — from the bright Garden Route sunshine to the filtered green light of the forest interior. The temperature drops. The sound changes — birdsong replaces wind, and the creak of ancient trees replaces the sound of the ocean. The smell of the forest — damp earth, decaying leaves, and the faint sweetness of forest flowers — is one of the most distinctive and evocative in South Africa.
The Giant Yellowwoods
The Diepwalle forest contains some of the largest and oldest Outeniqua yellowwood trees (Podocarpus falcatus) in South Africa. Several individual trees on the Elephant Trail are estimated to be over 800 years old — they were already ancient when the first European settlers arrived at the Cape. Standing at the base of one of these giants, looking up at a trunk that disappears into the canopy 30–40 m above, is a genuinely humbling experience.
The King Edward VII Tree — one of the most famous individual trees in South Africa — is accessible on or near the Elephant Trail. This enormous Outeniqua yellowwood is one of the largest trees in the country and has been a landmark in the Knysna forest for centuries.
The Forest Floor
The Diepwalle forest floor is as rich as the canopy above. Tree ferns create a prehistoric-looking understorey, wild orchids flower in the damp hollows, mosses and lichens cover every surface, and the fallen trunks of ancient trees are colonised by fungi, ferns, and seedlings. Walking slowly and looking carefully at the forest floor reveals a world of extraordinary complexity and beauty.
The Streams
Several clear, dark-stained forest streams cross the Elephant Trail — their water coloured by tannins from the forest leaf litter. These streams are the lifeblood of the forest, and the sound of running water accompanies much of the trail. Cape clawless otters are present in the forest streams and tracks are regularly found on the sandy banks.
The Knysna Forest: A Botanical Marvel
The Knysna forest is classified as Afromontane forest — a forest type that once stretched in a continuous belt from the Cape to East Africa along the mountain ranges of the continent. The Knysna forest is the southernmost and westernmost remnant of this great forest system, and its isolation has given it a distinctive character and a high level of endemism.
Key tree species to look for on the Diepwalle trails:
- Outeniqua yellowwood (Podocarpus falcatus) — South Africa's national tree; the dominant canopy species in the Diepwalle forest; reaching 40 m in the finest specimens
- Real yellowwood (Podocarpus latifolius) — a second yellowwood species; slightly smaller than the Outeniqua but equally impressive
- Cape fig (Ficus sur) — a large, spreading fig tree common in the forest margins and stream banks
- White stinkwood (Celtis africana) — a medium-sized tree with distinctive pale bark; common throughout the forest
- Ironwood (Olea capensis) — one of the hardest and most durable timbers in South Africa; the tree that drove the Knysna timber industry
- Tree ferns (Cyathea capensis) — the prehistoric-looking understorey plants that give the Diepwalle forest its distinctive character
Wildlife
- Knysna elephant — present in the forest; almost never seen; tracks and dung occasionally found on the trail; the knowledge of their presence transforms the experience
- Knysna turaco — the jewel of the Knysna forest; its crimson wing feathers flash through the canopy; its loud, distinctive call is the sound of the forest
- Narina trogon — one of Africa's most beautiful birds; patient forest walkers are rewarded with sightings in the denser forest sections
- Crowned eagle — Africa's most powerful eagle; nesting in the tall yellowwood trees; occasionally seen soaring above the forest canopy
- Samango monkey — endemic to South African forests; frequently heard crashing through the canopy; occasionally seen in the forest margins
- Bushbuck — the forest antelope; frequently seen in forest clearings and along stream banks
- Blue duiker — one of South Africa's smallest antelopes; shy and easily missed; found in the denser forest sections
- Cape clawless otter — in the forest streams; tracks regularly found on sandy banks
- Leopard — present in the Knysna forest; extremely rarely seen; tracks occasionally found
- Forest butterflies — the Diepwalle forest supports an extraordinary diversity of forest butterflies; look for them in the sunlit clearings
What to Pack: Hiking Food & Gear for the Diepwalle Trails
Hiking Food for the Diepwalle Trails
The Diepwalle Elephant Trails are day hikes — no overnight accommodation is available in the forest. Food planning is straightforward but important, especially for the full Elephant Trail (Red Route) which takes 5–6 hours.
The forest's cool, damp atmosphere means you may not feel as thirsty as on an exposed mountain trail — but hydration is still important, especially on the longer Red Route. Carry at least 1.5–2 litres of water per person.
- Trail snacks: High-protein freeze-dried snacks from Nature's Intention, nut butter sachets, freeze-dried fruit, and energy bars — eat at one of the forest stream crossings or in a sunlit clearing
- Lunch: A cold-soak freeze-dried meal eaten in the forest — one of the most atmospheric lunch spots in South Africa
- Water: Carry all water from Knysna or the forest station; the forest streams are available but should be treated before drinking

Gear Checklist
- Daypack (15–20 L)
- Waterproof jacket — essential; the Knysna forest receives significant rainfall and the canopy drips long after rain has stopped
- Warm mid-layer (the forest interior is significantly cooler than the surrounding Garden Route; even in summer, a layer is useful)
- Trail shoes or hiking boots with good grip (the forest paths can be slippery when wet)
- Insect repellent (the forest can have midges and mosquitoes, especially near streams)
- Water — at least 1.5–2 litres per person
- Sunscreen (less critical in the forest but useful for the forest station area)
- Headlamp (in case the Red Route takes longer than expected)
- First aid kit
- Binoculars (for the Knysna turaco, Narina trogon, and crowned eagle)
- Camera with good low-light capability (the forest interior is dark; a phone camera often struggles)
Permits and Access
The Diepwalle Elephant Trails are managed by SANParks as part of the Garden Route National Park. Entry fees apply.
- Entry fee: SANParks conservation fee applies; book through SANParks (sanparks.org) or pay at the Diepwalle Forest Station
- Opening hours: The forest station has set opening and closing times — confirm current hours with SANParks before your visit; start the Red Route early to ensure you complete it before closing time
- No overnight accommodation: The Diepwalle trails are day hikes only; overnight hiking in the Knysna forest requires a separate permit and is limited
- Fires: Strictly prohibited throughout the forest
Tip: Start the Elephant Trail (Red Route) early — by 8–9 AM at the latest. The 18 km route takes 5–6 hours and you need to be back at the forest station before closing time. The forest is at its most atmospheric in the early morning, when the light is low and the birds are most active.
Getting There
- From Knysna: Take the N2 east towards Plettenberg Bay, then the R339 north towards Uniondale. The Diepwalle Forest Station is approximately 20 km from Knysna on the R339. Total drive approximately 25–30 minutes.
- From George: Take the N2 east to Knysna, then the R339 north. Total distance approximately 80 km (about 1 hour).
- From Plettenberg Bay: Take the N2 west to the R339 junction, then north to Diepwalle. Total distance approximately 35 km (about 35 minutes).
- Nearest airports: George Airport (~80 km). Car hire is recommended.
Combining Diepwalle with Knysna
Diepwalle is best combined with a stay in Knysna — one of the Garden Route's finest towns and the ideal base for forest hiking.
- Knysna Lagoon: One of the most beautiful estuaries in South Africa; boat trips, kayaking, and the famous Knysna Heads are all within easy reach
- Knysna Waterfront: Excellent restaurants, craft shops, and the Knysna Oyster Company — fresh Knysna oysters are the obvious post-hike reward
- Featherbed Nature Reserve: A private nature reserve on the western head of the Knysna Lagoon; accessible by ferry and offering excellent fynbos and coastal walks
- Knysna Elephant Park: A sanctuary for rescued elephants near Knysna; a different but complementary elephant experience to the wild Knysna elephants of Diepwalle
Tips for First-Time Diepwalle Hikers
- Start early — the forest is most atmospheric in the early morning; the birds are most active and the light is most beautiful
- Walk slowly — the Diepwalle forest rewards slow, attentive walking; the details — the orchids, the fungi, the forest floor — are as rewarding as the giant trees
- Look up — the canopy is where the Knysna turaco and crowned eagle live; scan the upper branches regularly
- Listen for the Knysna turaco — its loud, distinctive call is unmistakable; once you know it, you'll hear it throughout the forest
- Carry a waterproof jacket — the Knysna forest can receive rain at any time of year; the canopy drips long after rain has stopped
- Respect the forest — stay on the marked trails; the forest floor is fragile and easily damaged by off-trail walking
- Remember the elephants — you are walking in their forest; the knowledge of their presence, even if you never see them, is one of the most powerful aspects of the Diepwalle experience
Why the Diepwalle Elephant Trails Are Unlike Any Other South African Hike
The Diepwalle Elephant Trails do not offer the dramatic views of the Drakensberg, the coastal spectacle of the Otter Trail, or the botanical diversity of the Cedarberg. What they offer is something rarer and more subtle: the experience of walking through one of the oldest and most intact indigenous forests in South Africa, in the company — however distant — of the last wild elephants of the Garden Route.
The ancient yellowwoods. The Knysna turaco flashing crimson through the canopy. The dark, tannin-stained streams. The profound silence of the forest interior. And the knowledge, always present, that somewhere in these ancient trees, the last Knysna elephants are moving through their forest.
Walk slowly. Look carefully. And listen for the elephants.
