Bolt Head to Bolt Tail is a Site of Special Scientific Interest (SSSI) along a section of the southern coastline of Devon, England that is within the South Devon National Landscape. This protected area is located between Hope Cove and the Kingsbridge Estuary and includes headlands called Bolt Head and Bolt Tail as well as Bolberry Down and landforms such as Greystone Ledge and Soar Mill Cove. The South West Coast Path traverses this protected area. This area is protected because of the plant, lichen, invertebrate and bird diversity present here.
