==Treyarnon Bay== Treyarnon has a car park (often full at busy times), toilet facilities and a useful shop (Treyarnon Bay Beach Store). It is a popular spot for bodyboarding, where most surfers go to the beach next door, Constantine Bay. Dogs are allowed all year around and there is lifeguard cover in the summer. The beach has a very dangerous left hand side. The tide comes in very quickly around the island on the left hand side, often leaving people cut off from the mainland. It has a partially constructed rockpool which acts as a swimming pool for older children at low tide.
