The Broomway is a tidal byway out to Foulness Island over Maplin Sands at the mouth of the Thames estuary. The route is so called because it used to be marked by branches of Broom placed at regular intervals on the route. However these have long since gone and the path is now unmarked. The path is dangerous because the tide comes in as fast as you can run and there are quick sands and mud in places if you stray off the route. Foulness Island itself is part of a firing range and most of it is "out of bounds" to the public with the exception of the south east corner of the island, which has a couple of villages and farms. The only road to the island can only be used by MOD permit holders, so the only way for the public to reach the island is by boat or by walking the Broomway.
