Known locally as Pro'stock, Porthoustock is an east-facing beach with a large flat expanse of coarse dark sand and shingle that is popular with divers as there are lots of shipwrecks in the area around the Manacles. 

The beach is overlooked by the reamins of former roadstone quarry.

Swimming with care. 

Parking is allowed at the back of the beach taking care not to obstruct the boats of the local fishermen. There are toilets behind the beach and some picturesque thatched cottages. Coastal footpath enthusiasts can walk north on the unofficial coastpath to Porthkerris.
