The South Devon Area of Outstanding Natural Beauty (AONB) covers 337 square kilometres, including much of the South Hams area of Devon and the rugged coastline from Jennycliff to Elberry Cove near Brixham. The purpose of an Area of Outstanding Natural Beauty is to conserve and enhance the area's natural beauty. In South Devon this includes: undeveloped coastline, estuaries, geological and geomorphological features, expansive panoramic views, ancient agricultural field pattern, Devon banks, areas of high tranquility, dark night skies and natural nightscapes, historic features, green lanes, well known cultural associations, picturesque villages and hamlets. South Devon AONB was formally designated in August 1960 under the National Parks and Access to the Countryside Act 1949 (South Devon AONB Management Plan 2009-14). The highest point in the AONB is Blackdown Camp at 199 metres above sea level.
