How to Hike the Undercliff Path Devon

The Undercliff Path in Devon is one of the most breathtaking and lesser-known coastal walking routes in southern England. Stretching along the dramatic limestone cliffs between Lyme Regis and Seaton, this trail offers hikers a unique blend of geological wonder, rich biodiversity, and panoramic sea viewsall without the crowds often found on more famous coastal paths like the South West Coast Path. While technically part of the larger Jurassic Coast World Heritage Site, the Undercliff Path remains relatively obscure, preserving its wild charm and tranquility. For those seeking an immersive, off-the-beaten-track experience that combines natural history with physical adventure, mastering how to hike the Undercliff Path Devon is essential. This guide provides a comprehensive, step-by-step walkthrough, from planning to execution, ensuring you navigate this challenging yet rewarding route safely and meaningfully.

Step-by-Step Guide

1. Understand the Route and Its Sections

The Undercliff Path is not a single, clearly marked trail but a network of footpaths, old tramways, and informal tracks that follow the base of the Undercliffa landslide-prone area formed by centuries of coastal erosion. The most commonly hiked section runs approximately 7 miles (11 km) from Lyme Regis to Seaton, though some choose to extend it to Axminster or shorten it to just the central stretch. The path is divided into three distinct segments:

• Lyme Regis to Charmouth (3 miles): Begins at the Cobb Harbour, ascends gently through the towns historic streets, then descends via steep staircases and steps toward the beach. This section is the most accessible and popular with tourists.
• Charmouth to Seatoun (3.5 miles): The heart of the Undercliff. This is where the path becomes more rugged, winding through dense woodland, along unstable cliff edges, and past fossil-rich shingle beaches. Navigation becomes more critical here.
• Seatoun to Seaton (0.5 miles): A gentle, paved finish through the village of Seatoun and into Seatons town center, where public transport and amenities are readily available.

Understanding these segments allows you to plan rest points, water stops, and exit strategies based on your fitness level and time constraints.

2. Choose Your Starting Point and Direction

Most hikers begin in Lyme Regis due to its parking availability and public transport links. However, starting in Seaton offers a more gradual ascent and a rewarding downhill finish. Consider these factors when choosing direction:

• Lyme Regis to Seaton (Eastward): Ideal for those who want to end their hike with a flat, easy walk into town and access to cafes and buses. The initial descent into the Undercliff is steep but short.
• Seaton to Lyme Regis (Westward): Better for experienced walkers seeking a challenge. The climb out of the Undercliff near Charmouth is steep and exposed, requiring good stamina.

For first-timers, we recommend starting in Lyme Regis. The path is better signposted from this end, and the views from the lower trail looking back toward the town are spectacular.

3. Plan Your Timing and Season

The Undercliff Path is best hiked between late April and early October. During these months, the weather is most stable, vegetation is lush, and the risk of landslides is lower. Avoid winter months (NovemberMarch) when rain-saturated ground increases landslide danger and paths become muddy and impassable.

Start your hike earlyby 8:00 AM at the latest. This ensures you have ample daylight, especially if you plan to complete the full route. The path receives little shade in summer, so early mornings are cooler and more comfortable. Additionally, parking in Lyme Regis fills quickly; arriving early secures a spot near the Cobb or the towns main car parks.

4. Prepare Your Gear

Unlike well-maintained national trails, the Undercliff Path requires specialized preparation. Heres what you must bring:

• Sturdy hiking boots: Waterproof, ankle-supporting boots with aggressive tread are non-negotiable. The path includes loose shale, wet roots, and uneven limestone slabs.
• Water and snacks: Carry at least 2 liters of water per person. There are no reliable water sources along the route. Pack high-energy snacks like nuts, energy bars, and dried fruit.
• Weather-appropriate clothing: Even in summer, coastal winds can be chilly. Wear moisture-wicking layers, a waterproof shell, and a hat. Avoid cottonit retains moisture and increases risk of hypothermia.
• Navigation tools: A physical map (OS Explorer OL14) and a fully charged smartphone with offline maps (OS Maps or Gaia GPS) are essential. Signal is patchy along the Undercliff.
• First aid kit: Include blister treatment, antiseptic wipes, tweezers, and pain relief. The path is remote; help is not always nearby.
• Headlamp or flashlight: Even if you start early, delays can happen. Always carry a backup light source.

Do not rely on your phones GPS alone. Batteries drain quickly in cold or windy conditions, and signal loss is common in the narrow, tree-covered ravines of the Undercliff.

5. Begin Your Hike: From Lyme Regis to the Undercliff Entrance

Start at the historic Cobb Harbour. Walk through the town center toward the Lyme Regis Museum, then follow signs for the Undercliff Walk or Coastal Path. Youll soon reach a series of steep stone steps descending from the main road near the old railway tunnel. These steps lead directly into the Undercliffs lower level.

Take your time here. The descent is narrow and slippery when wet. Hold onto the handrails, watch your step, and avoid rushing. Once at the bottom, youll enter a wooded corridor lined with ancient oaks and ferns. This is where the true character of the Undercliff begins.

6. Navigate the Undercliff Corridor: Charmouth to Seatoun

This is the most technically demanding section. The path is not always clear. Look for faded white waymarkers on trees and occasional stone posts. In some areas, multiple trails branch offchoose the one that runs parallel to the cliff edge and follows the old tramway bed. Avoid shortcuts through dense undergrowth; they lead to unstable ground.

Key landmarks to watch for:

• Charmouth Beach: Reach this after 3 miles. Take a break here. The beach is rich in fossilslook for ammonites and belemnites in the shingle. Never climb the cliff face; erosion is constant.
• The Fossil Forest: A few hundred yards past Charmouth, youll pass a cluster of petrified tree stumps embedded in the cliffside. This is a geological highlighttake photos but do not remove any specimens.
• Black Ven: A notorious landslide area between Charmouth and Seatoun. Stay on the marked path. Warning signs are posted, but they are often faded. If you see fresh mudslides or cracks in the ground, turn back or reroute.

Throughout this section, the path is mostly flat but narrow. Watch for tree roots, exposed rocks, and hidden holes. Use trekking poles if you have themthey provide stability on loose terrain.

7. Final Stretch: Seatoun to Seaton

After the Undercliffs wildness, the final leg feels like a gentle reward. The path emerges from the trees near Seatouns old mill and follows a quiet lane lined with hedgerows. Youll pass the Seatoun Community Centre and cross a small footbridge over the River Axe.

As you enter Seaton, the path becomes paved. Follow signs to the town center, where youll find public toilets, cafes, and bus stops. The Seaton Tramway offers a charming return to Lyme Regis if you prefer not to retrace your steps.

8. Complete Your Hike with Reflection

Before leaving Seaton, take a moment to reflect. The Undercliff Path is more than a hikeits a journey through time. The cliffs you walked beside were formed over 180 million years ago. Fossils you may have seen are remnants of ancient seas. This trail connects you to deep Earth history.

Consider logging your experience in a journal or sharing your photos responsibly on social media (without tagging exact locations to prevent overcrowding). Leave no trace. Pack out everything you brought in.

Best Practices

1. Respect the Geology

The Undercliff is a living geological laboratory. The cliffs are constantly shifting. What was solid ground yesterday may be a landslide today. Never climb on cliff faces, dig into the rock, or remove fossils. The Jurassic Coast is protected under UK law, and disturbing natural features can result in fines.

2. Stay on Designated Paths

Off-path walking increases erosion and endangers your safety. The Undercliffs instability is precisely why the path existsit was carved to avoid the most dangerous zones. Straying even a few feet can lead to serious injury or death. Always follow waymarkers and avoid shortcut trails.

3. Travel in Groups When Possible

While solo hiking is possible, the Undercliff Paths remoteness makes group travel safer. If you must go alone, inform someone of your route and expected return time. Consider carrying a personal locator beacon (PLB) if youre venturing into areas with no mobile signal.

4. Leave No Trace

There are no bins along the Undercliff. Carry all wasteincluding food wrappers, tissues, and biodegradable itemsuntil you reach Seaton. Even apple cores and banana peels disrupt local wildlife. The area is home to rare species like the Dartford warbler and the rare Portland snail; minimize your impact.

5. Be Aware of Tides and Weather

Although the Undercliff Path is above the tide line, some access points near Charmouth Beach can be cut off during high tide. Check tide times before you leave. If the beach below is flooded, do not attempt to crosswait or find an alternate route. Sudden fog can roll in off the sea, reducing visibility. If you lose your bearings, stop, assess, and wait for conditions to improve.

6. Protect Wildlife

Early morning and dusk are peak times for foxes, badgers, and deer. Keep dogs on a lead, especially in wooded areas. Birds nest in the undergrowth during springkeep noise to a minimum between March and July. Never feed wildlife.

7. Know Your Limits

The Undercliff Path is not a leisurely stroll. Its a moderate-to-difficult hike with uneven terrain, steep sections, and no facilities. If youre not accustomed to hiking on rough ground, consider a shorter segment. The path is not suitable for strollers, wheelchairs, or young children without significant assistance.

8. Document Responsibly

Photography is encouraged, but avoid climbing on rocks or disturbing natural features for the perfect shot. Use drones only if you have a Civil Aviation Authority permitflying over protected heritage sites without authorization is illegal.

Real Examples

Example 1: Sarahs First Undercliff Hike A Solo Journey

Sarah, a 32-year-old graphic designer from Bristol, decided to hike the Undercliff Path after reading about its fossil beds. She started in Lyme Regis at 7:30 AM on a clear May morning. She followed the OS map religiously, taking breaks at Charmouth Beach to examine ammonites. At Black Ven, she noticed fresh mudslides and chose to pause rather than risk crossing. She used her Gaia GPS app to confirm her position and waited an hour until the path stabilized. Sarah reached Seaton by 3:00 PM and took the tram back to Lyme Regis. It was the most peaceful hike Ive ever done, she said. I felt like I was walking through a living museum.

Example 2: The Thompson Family A Multi-Generational Experience

The Thompsons, a family of five from Exeter, planned a weekend trip to the Undercliff. They split the hike into two days. On Day 1, they walked from Lyme Regis to Charmouth, staying overnight in a B&B. On Day 2, they completed the route to Seaton. Their 7-year-old daughter, Mia, loved spotting fossils. The parents carried her in a backpack during steep sections. We made it a learning trip, said Mr. Thompson. We talked about geology, erosion, and why we dont take things from nature. She still talks about the rock dinosaurs.

Example 3: Marks Emergency Encounter

Mark, a 45-year-old fitness instructor, attempted the Undercliff Path alone in November. He ignored weather warnings and started in heavy rain. Near Seatoun, he slipped on wet shale and twisted his ankle. He had no phone signal. He used his headlamp to signal a passing dog walker, who called emergency services. Mark spent the night in a local clinic. I thought I was tough enough, he admitted. I wasnt. The Undercliff doesnt care how fit you are. It only respects preparation.

Example 4: The Photographers Journey

James, a landscape photographer from Cornwall, spent three days photographing the Undercliff at sunrise, midday, and sunset. He captured the mist rolling over the cliffs at dawn, the golden light filtering through the trees at noon, and the deep blues of the Channel at dusk. He used a drone only in permitted zones and always walked the path on foot to find the best angles. His exhibition, Whispers of the Undercliff, later won regional acclaim. The path teaches patience, he said. You dont conquer ityou listen to it.
