The name East Caithness Cliffs refers to weathered sandstone cliffs on the east coast of Caithness in Scotland. The cliffs, which rise to 150 m at Berriedale, provide ideal nesting conditions for breeding seabirds, and are protected by several overlapping conservation designations:The East Caithness Cliffs Special Area of Conservation (SAC) covers the cliffs from the southern boundary of Caithness to just south of Wick, an area of 457 hectares (4.57 km2) in total. The East Caithness Cliffs Nature Conservation Marine Protected Area protects the sea up to 2 km from the SAC, an area of 11,400 hectares (114 km2) in total. The East Caithness Cliffs Special Protection Area (SPA), which covers 11,696 hectares (116.96 km2), includes both the cliffs of the SAC and the seaward area of the MPA.
