Why not go eco-friendly and walk or cycle here? The Clay Trails are a collection of multi-use trails for cycling, walking, horse-riding and wheelchairs.  They are short, easy to navigate and traffic free trails, connecting Wheal Martyn with Bugle, the Eden Project and St Austell, including local bus and train stations. 

You can also use the trails to discover the surrounding clay country’s unique industrial landscape, flora and fauna.
