Sharpitor Cist is around 100 yards from the B3212 to Princeton. There is a well preserved cist and two orthostats, NW & SE of the cist.
You can park at SX557707 approximately. Walk NE parallel to the road for around 150 yards until you see two parallel stones, 3 feet high. The cist is between these stones.
