At the southern tip of the peninsula is Dreswick Point, the southeastern-most point of the Manx mainland, whilst St. Michael's Isle (popularly known as Fort Island) is connected at the northern end of the peninsula by a narrow causeway.
The Castletown Golf & Country Club (also a hotel) is set on the peninsula and the land connecting it with Derbyhaven and has been the scene of many international championships. In 2005 the Duke of York Young Champions Trophy golf championships were held at the club.
