Compacted gravel surface means it's still rideable even when it's wet. There does tend to be a lot of dog walkers along here.

The harbor lock is still under repair. Currently, there are no ships worth seeing in the harbor. Just an old shipwreck. So, nothing really worth seeing.

Charlestown Harbour is the last open 18th-century Georgian harbour in the UK and is recognized as a UNESCO World Heritage Site. Renowned for its historic tall ships and picturesque setting, the harbour remains a vibrant working port and a popular filming location for TV and film productions such as Poldark and Taboo.

The Harbour gate failed in a recent storm due in part to a long-term lack of maintenance. As a result, the ships that were in the harbour all have been stranded every time the tide goes out. They have recently put shipping containers filled with aggregate where the gate was to keep water in as a temporary "fix"

A well sheltered, rough sand and pebble beach which is great for swimming, snorkelling and rock pooling. A waterfall lands on the beach from the steam, to add to the attractiveness of the area.

Yes, the region offers many circular routes. A great example is the The China Clay Trail loop from St Austell, which provides a fascinating look into the area's industrial heritage over about 5.2 miles (8.4 km). For a more challenging coastal experience, the View of Pentewan Sands loop from St Austell is a difficult but rewarding 14.7-mile (23.6 km) hike with fantastic sea views.
The Pentewan Trail is an excellent choice for families. It's a largely flat, traffic-free path that follows a former tramway along the St. Austell River to the coastal village of Pentewan. The route is well-surfaced and suitable for walkers of all ages.
Most trails in the St. Mewan area are dog-friendly, but it's always best to keep dogs on a lead, especially near farmland or on coastal cliffs. The Pentewan Trail and the Clay Trails are popular with dog walkers. Always be prepared to clean up after your pet to keep the trails enjoyable for everyone.
Many routes pass through or near villages with traditional Cornish pubs. For example, the St Austell & Charlestown loop takes you to the historic harbour of Charlestown, which has several pubs and restaurants perfect for a mid-hike break.
The Clay Trails are a unique network of paths that wind through the dramatic landscape of Cornwall's former china clay industry. You'll see towering white spoil heaps, known as the 'Cornish Alps', and old quarries now filled with turquoise water. The difficulty varies; some sections are flat, while others, like parts of The Eden Project & Wheal Martin Trail, involve steeper climbs that reward you with panoramic views.
St Austell has several public car parks, which are convenient starting points for many trails, including those heading into the Clay Country or towards the coast. For routes starting from the train station, there is an adjacent car park. It's advisable to check local signage for time limits and charges, especially during peak season.
Yes, St. Mewan is very close to the South West Coast Path. You can easily access stunning coastal sections. A popular route combines the Pentewan valley with the coastline at Black Head, offering breathtaking views over St. Austell Bay and Mevagissey Bay. Another option is the walk from Pentewan to the picturesque fishing village of Mevagissey.
The trails are highly regarded by the komoot community, with an average rating of 4.6 stars. Hikers frequently praise the unique scenery of the Clay Trails and the beautiful coastal views. The mix of industrial heritage and natural landscapes is often mentioned as a highlight of hiking in the region.
Absolutely. The Pentewan Trail is one of the best options for beginners, as it's mostly flat and easy to follow. For a short coastal walk, the Black Head loop is relatively easy, though it does have some gentle ascents and descents. Many of the shorter paths within the Clay Trails network are also well-suited for a gentle stroll.
Yes, St Austell's train station is a great hub for starting several hikes. From there, you can directly access trails leading to Charlestown, the Eden Project, and into the Clay Country, making it easy to explore the area without a car.
The entire region is steeped in history. The Clay Trails explore the heart of Cornwall's china clay industry, while the Pentewan Trail follows the route of a 19th-century horse-drawn tramway. For a mix of coastal and ancient history, the Silvermine Valley Cove β Hallane Mill Beach loop from Polgooth passes near the remains of an Iron Age fort at Black Head.
Komoot provides detailed maps for every route. For the Clay Trails specifically, you can find a helpful overview map and guide available as a PDF from the local council. You can download it from the St Austell Town Council website.
