The Wheal Martyn & the Eden Project route is generally considered moderate for mountain biking. While many sections of the wider Clay Trails network are easy and suitable for all skill levels, this specific 44.4km route includes some steep slopes and requires good fitness and advanced riding skills in parts. There are easier mountain bike options within the network, such as a 15.4km loop from the Eden Project with less elevation gain.
You'll encounter a diverse mix of surfaces, including paved sections, asphalt, gravel, and unpaved paths. The route often follows old china clay railway lines and tramways, which are now peaceful cycle paths, predominantly gravel. Be prepared for some rocky areas, grass, and heathland, especially on the more challenging segments.
The route offers a unique journey through Cornwall's china clay country. You'll pass by active and disused mines, clay pits with distinctive green pools, and historic industrial structures like overgrown chimneys. Highlights include Wheal Martyn Clay Quarry, the Wheal Martyn Clay Trail, and the Stone Bridge Over River Par in North Hill Wood. Expect spectacular panoramic views of St Austell Bay and the unique 'moon-like' landscape of the clay pits, including Baal Pit.
Yes, this route is part of the wider Clay Trails network and connects to several other paths. You'll find sections that are part of the National Cycle Network Route 2 Plymouth to St. Austell, Par Beach Trail, Saints Way, and various segments of the Wheal Martyn Trail, Bugle Trail, and Higher Tramway.
Parking is available at both Wheal Martyn China Clay Museum and the Eden Project, as the trail connects these two major attractions. Specific parking details and potential fees should be checked directly with the venues.
As part of the multi-use Clay Trails network, the route is generally accessible to dogs. However, specific rules regarding leashes may apply, especially within the grounds of Wheal Martyn and the Eden Project. Always keep dogs under control and be mindful of other users, including cyclists, walkers, and horse riders.
The trail can be enjoyed year-round, but spring and autumn often offer the most pleasant conditions with milder weather and beautiful scenery. Summer can be busy, especially around the main attractions. Be aware that some unpaved sections might become muddy or slippery after heavy rain, particularly in winter.
Riding the Clay Trails themselves typically does not require a permit or fee. However, if you plan to enter the grounds of the Eden Project or Wheal Martyn China Clay Museum, standard admission fees will apply. The Eden Project sometimes offers discounts for visitors arriving by bike.
Yes, you'll find cafes and refreshment options at both the Eden Project and Wheal Martyn China Clay Museum. The route also passes through Ruddlemoor village green, and there are likely other local establishments in nearby villages. It's always a good idea to carry water and snacks, especially for the longer sections.
While the overall route is classified as moderate, some sections of the wider Clay Trails are described as easy and suitable for all skill levels, including families. For younger or less experienced riders, consider shorter, flatter segments of the Clay Trails, or the 15.4km Wheal Martyn Clay Trail loop from the Eden Project, which has less elevation gain and is more family-friendly.
Given the varied terrain and moderate difficulty, it's recommended to bring a mountain bike in good working order, a helmet, water, snacks, and appropriate clothing for the weather. A basic repair kit and spare inner tube are also advisable. Consider a map or GPS device, as the trail network can be extensive.
