Mount Michael Volcano Lava Lake

St Michael's Mount is a tidal island in Mount's Bay near Penzance, Cornwall, England. The island is a civil parish and is linked to the town of Marazion by a causeway of granite setts, passable between mid-tide and low water. It is managed by the National Trust, and the castle and chapel have been the home of the St Aubyn family since around 1650.
