The Pentewan trail is a lovely traffic free cycle and walking path running from St Austell to Mevagissey.
The trail follows National Cycle Route 3 along an old railway line and the St Austell River for part of the way and also includes a woodland section through King's Wood. There is also a short detour to the beautiful Lost Gardens of Heligan which boasts 200 acres of gardens including Victorian Productive Gardens, romantic Pleasure Grounds, and a lush sub-tropical Jungle. From Heligan the path descends to the finish point at the lovely harbour at Mevagissey.
Also please note that at King's Wood there is the option of heading to the beach and harbour at Pentewan.

At one end of the route there's the Sharksfin in Mevagissey. The pub is ideally located next to the quay with lovely views across village's impressive harbour. They do excellent seafood including a particularly popular fish and chips. The interior is very attractive too, being decorated with works by local artists. You can find them at a postcode of PL26 6QU for your sat navs.
The trail is a nice one to do with your dog though there are likely to be quite a few cyclists so it's best to keep them under control. The Sharksfin mentioned above is also dog friendly.
Further Information and Other Local Ideas
The Mevagissey Walk uses part of the trail and the coastal path to create a circular walk around the village. The picturesque fishing village is also well worth exploring with its photogenic harbour and interesting narrow streets full of quaint old shops and pretty cottages.
In St Austell you could enjoy a stroll around the lovely Pinetum Gardens. The 30-acre garden is home to one of the largest plant collections in the county.
