South of Bristol and Bath, the Mendip Hills (Black Down: ) are the first group of hills in South West England. The Purbeck Hills (and their continuation onto the Isle of Wight) line the south coast, and a number of other groups of hills are also present in the area: the Quantock Hills (Will's Neck: ), Blackdown Hills, Dorset Downs, Salisbury Plain and Cranborne Chase. Glastonbury Tor, although of only modest height (), is significant for its claimed association with Arthurian legend.
