South West Coast Path: Seaton to Lyme Regis via The Undercliff

This challenging section of the South West Coast Path is approximately 11.2 to 12 km (7 to 7.5 miles) one way. It typically takes 3.5 to 4.5 hours to complete, but allow extra time for enjoying the unique scenery and navigating the difficult terrain.

The trail is officially rated as 'difficult' and 'arduous'. The terrain is characterized by a 'tumbled coastline' with deep fissures and undulating paths, often slippery due to clay soils, especially after rain. You'll navigate through dense woodlands with numerous steep ascents and descents. Many hikers recommend using walking poles for stability.

You can find parking in both Seaton and Lyme Regis. In Seaton, parking is available near the seafront. In Lyme Regis, options include car parks near the town centre or closer to the Cobb. Consider public transport or arranging a pick-up if you're only hiking one way, as it's not a circular route.

Both Seaton and Lyme Regis are served by local bus routes, connecting them to larger towns in Devon and Dorset. This makes it feasible to hike one way and use public transport to return to your starting point, or to access the trailheads without a car.

Yes, dogs are generally allowed on the South West Coast Path. However, due to the challenging and often slippery terrain, dense vegetation, and the presence of wildlife within the The Undercliff National Nature Reserve, it's advisable to keep dogs on a lead, especially in sensitive areas or near cliff edges. Ensure your dog is fit enough for an arduous hike.

Given its 'difficult' and 'arduous' rating, with uneven, slippery ground and steep sections, this trail is generally not recommended for young children or those unaccustomed to challenging hikes. There are no escape routes once you're in The Undercliff, requiring commitment to the entire section.

Spring (April-May) is particularly beautiful, with carpets of bluebells, wild garlic, and daffodils, and vibrant birdsong. However, the trail can be very muddy and slippery after wet weather, which is common in spring and autumn. Summer offers drier conditions but can be busy. Always check weather forecasts before you go.

No, there are no permits or entrance fees required to hike through the Axmouth to Lyme Regis Undercliffs National Nature Reserve. It is freely accessible to the public, though it is a protected area, so please respect the natural environment and stay on marked paths.

The trail itself is a highlight, passing through the unique 'rainforest-like' environment of The Undercliff National Nature Reserve. While much of the route is enveloped by dense woodlands, you'll get occasional glimpses of the coast. As you approach Lyme Regis, you'll find stunning views over The Cobb, Lyme Regis and Lyme Regis Beach from Langmoor and Lister Gardens.

The Undercliff is part of the Jurassic Coast World Heritage Site and is one of the largest active coastal landslide systems in Western Europe. This continuous land movement has created a wild, 'jungle-like' topography. Its sheltered, humid conditions foster a rich biodiversity, including unique ferns like Hart's tongue fern, and a diverse range of specialist insects. It's a true biodiversity hotspot.

Given the trail's difficulty and terrain, sturdy hiking boots with good ankle support are essential. Walking poles are highly recommended for stability on slippery and uneven sections. Bring plenty of water, snacks, waterproof clothing, and a map or GPS device, as mobile signal can be intermittent. There are no facilities within The Undercliff itself.

Crucially, once you enter The Undercliff National Nature Reserve between Seaton and Lyme Regis, there are no alternative paths leading inland or towards the sea. You are committed to completing the entire section until you reach Lyme Regis. This highlights the importance of being well-prepared and fit enough for the full hike.
