Rocky beaches and coves is what Cornwall is all about, for me. Carnewas beach and the Bedruthan Steps are probably the most spectacular example. A steep and narrow, winding staircase takes you all the way down from the clifftop to the beach. At low tide, it’s a lovely sandy beach where you can poke at mussel colonies and stranded jellyfish. At high tide, the beach is under several metres of water, and so is the bottom of the stairs.
