This stretch of the South West Coast Path is, without a doubt, unique and exceptionally beautiful. The path is fairly level and easy beyond Porthleven, but then becomes narrow in places with some steep ascents and descents. There is a special sense of wildness and isolation on the Peninsula, notably along Mullion and Predannack Cliffs which are part of the Lizard National Nature Reserve. Cormorants, shags, kittiwakes and black-backed gulls nest on Mullion Island. The island is made of lava which is 350 million years old.
