Godrevy Head to St Agnes is a coastal Site of Special Scientific Interest (SSSI) in north Cornwall, England], noted for both its biological and geological characteristics.

[2][3] The South West Coast Path runs through the SSSI and part of the coastline is owned by the National Trust.

The SSSI is predominantly situated on Devonian sandstones and shales, with the area around St Agnes formed from Grampound grit.

[1] The sand dunes, found around the east of the site at the Godrevy Towans, supports the nationally rare slender bird's-foot trefoil (Lotus angustissimus).

[1] Scarlet and gold star coral are present within the rocky intertidal shores, rare for the Cornish coast; with grey seal (Halichoerus grypus) having breeding sites within the inaccessible sea caves.
