Not a difficult find, near our HQ building, just by the public carpark at Keyhaven. This can become very busy in the summer, so beware the muggles!
Keyhaven is a wonderful hamlet with a few houses, the 'Gun Inn', the Keyhaven Yacht Club & Hurst Castle Sailing Club. It is on the edge of the salt marshes which are designated a SSSI, and in view of Hurst Castle and the shingle spit that connects it to the mainland, forming the lagoon which provides good safe sailing when the tide is in.
