St Marys Well Bay Beach

St Marys Well Bay is a combination of coarse sand and pebbles. The beach is backed by Triassic sandstone and limestone cliffs with some great coast walks.

At low tide a sandbar runs parallel to the main beach and extends towards Sully Island.

Roadside parking is available just before the holiday park entrance.
