Bosigran walk


Starting at Carn Galva car park, the most striking features are the two engine houses, symbols of mining activity at Carn Galva, Watchcroft, Porthmoina and Porthmeor valleys. This walk then passes through an ancient landscape steeped in mining history, with stunning coastal and moorland views.
