The Worm's Head promontory marks the beginning of this four-mile stretch of golden sand. Set at the western tip of the peninsula, it bears the full might of Atlantic swells, and is popular with surfers, walkers and paragliders. Access is tricky, involving a walk down the cliff path. Look out for the hull of the Helvetia, wrecked on the beach in 1887. There can be strong undertows when the surf is high.
