Northey is an island in the Blackwater Estuary in Essex, connected to the mainland by a causeway that is covered by the tide twice every day. A large part of the island is salt marsh and tidal creeks and is a veritable twitchers' paradise.

A wonderful house in the form of a tower stands on the island and is available for holiday lets. The caretaker lives in the only other house on the Island.

When the tide is up, Northey is a magical world of marshes and sea breezes where your privacy will only be disturbed by seabirds. Visitors can enjoy sailing, windsurfing or doing not very much at all as they give in to the slow pace of Island life.

Northey Island and the adjoining South House Farm was given to the National Trust by Nora and Eric Lane in 1978.
