Hilbre Island

The Hilbre Islands are an archipelago consisting of three islands at the mouth of the estuary of the River Dee, the border between England and Wales at this point. The islands are administratively part of the Metropolitan Borough of Wirral. They are a Local Nature Reserve and are within the estuary Site of Special Scientific Interest. As of 2012, the islands have no permanent residents. The name is thought to derive from a chapel built on the Island and dedicated to St. Hildeburgh. Visitors typically travel by foot to the Islands from West Kirby.
