Kynance is the most painted cove on the Lizard peninsula — turquoise water over white sand between jagged stacks of green-and-red serpentine rock. The Lizard's unique geology (it's the only place in Britain where you see serpentine outcrops at the coast) gives Kynance its colour. At low tide the caves under Asparagus Island open up; at high tide the cove is a narrow strip of sand. National Trust; a five-minute drive from Lizard village.
