The peninsula is connected to the mainland at the eastern end; on the south (present-day Porth) is a natural harbour.

The South West Coast Path traces the perimeter of the eastern part of the peninsula.

[1][2] There is a gap in the peninsula, crossed by a modern bridge where there may have been originally a land-bridge; immediately before this there are three massive banks and ditches.

[1][3] There was an archaeological excavation of the site in 1939 by C. K. Croft Andrew; the project was abandoned on the outbreak of war and the findings were not published.

About 600 items of worked stone, over 4,000 shards of pottery, and objects of tin, copper and iron and glass were found.
