RV and tent pitches behind pub. Agree about the shower block, new and well-looked after. Also four double rooms available at £75 a night. Pub open every day from noon. Kitchen open for lunch and dinner every day except Monday. Great base for exploring the area.

The slight elevation of the Tollesbury road gives views clear across the marshes all the way to the buildings of West Mersea rising up on the slopes of Mersea Island.
