Seven Bays walk

Seven Bays (via bus)

The coast path crosses the top of the beach at Harlyn Bay where there is no alternative route. During neap tides this is accessible at all states of the tide but during spring tides this is underwater for around 1 hour at high tide. Therefore check tide times (and heights) before setting out to avoid a wait.

A one-way coastal walk, made circular via an initial bus journey, along the Seven Bays coast and around Trevose Head past the lighthouse.

After an initial bus journey from Haryln Bay to Porthcothan, the walk starts at the Porthcothan beach and follows the coast path past a series of inlets used by smugglers to the sandy beaches of Treyarnon and Constantine Bay. The route then passes Booby's Bay, where a buried shipwreck is sometimes revealed by storms, and climbs onto Trevose head past a collapsed cave to reach the lighthouse. The final part of the walk is above the sheltered sandy beaches of Mother Ivey's Bay and Harlyn Bay with an optional short extension to Trevone Bay.
