Close to the shore – so close that you can walk out to it at low tide – is this tiny island. It looks like an ideal artist’s or writer’s retreat, which indeed it once was: novelist Paul Bowles wrote The Spider’s House here in the 1950s. The island was developed in the 1920s by the French Count de Maunay-Talvande who perched his mansion on the tiny rock. You can stay or dine on the island with advance planning.
