tidal island in North East England
Access to Lindisfarne is affected by local tides. This point cannot be expressed enough as many people get stranded on the causeway every year requiring coastguard rescue (sometimes including helicopter rescue). Tide tables are available locally and are published on the internet.
Local bus service 477 runs from nearby Berwick-upon-Tweed, however it can be somewhat irregular due to tidal patterns, and does not run every day through winter months. Travellers are advised to make local enquiries before making arrangements around the bus service.
The main east coast road the A1 is conveniently located for Lindisfarne. The turning is located in the small village of Beal (which appears to consist only of The Plough Hotel and a service station, both on the eastern side of the road). The turning is signed as "Holy Island". The distance from the turning to the island is approximately 5 miles, including the tidal causeway.
The Pilgrim's Crossing is a clearly marked walking route from the mainland to the island that crosses the sand and mud. However, due to the tidal nature of this crossing, it is strongly advised that this route must only be attempted with an experienced local guide.
