 Small craft can pass between it and (the) Chiswick Mall on the Middlesex (left, generally north) bank for about two hours at high tide, but the small channel is generally impassable otherwise — at low tide it is possible to walk to it as it is a tidal island.Chiswick Eyot is one of 43 unbridged tidal islands which can be walked to from the mainland of Great Britain, dating back to the British Iron Age such tidal islands are occasionally associated with being sanctuaries and meeting places; some are named Holy Islands.The  eyot was long-owned by the rectory of Chiswick and its natural successors the Ecclesiastical Commissioners until 1934 when ownership passed to the local council.
