Priory Bay is the largest beach on Caldey Island. Access is by boat from Tenby's Castle Beach, the crossing taking about 20 minutes. Boats run Monday to Friday from Easter until October, and on Saturdays from May to September. Caldey Island is privately owned by the Cistercian monks, and unofficial landings are not allowed.
The beach is made up of coarse sand, backed by low dunes with pebbles lower down the beach. It is generally safe for bathing. Beyond the landing stage the beach becomes very rocky.
The village of Caldey is a short walk away and has toilets (with disabled facilities), a cafe with outdoor seating on a lawned area, a gift shop and post office. Dogs are allowed on the island but must be kept on a lead.
