St Loy's Cove is a small wooded valley and beach in the civil parish of St Buryan in Cornwall, England, UK. It is located two miles to the south of St Buryan churchtown, and between Penberth and Lamorna. There are just a few buildings in the cove, one of which, Cove Cottage, provides bed and breakfast and a cafe. St Loy's is within the Cornwall Area of Outstanding Natural Beauty (AONB), the Boscawen SSSI (Site of Special Scientific Interest) and is part of a GCR Geological Conservation Review site. The South West Coast Path passes through the cove.
