Walk the Pentewan Valley Trail The trail runs along the bed of an old narrow gauge railway from St Austell to Pentewan. Catch the bus to Pentewan, go to the beach and linger over a coffee and cake in the harbour. When you’re ready to set off again, take a leisurely stroll back to Bosinver along the Pentewan Valley Trail.
