The route, said to be 600 years old covering six miles (10km), is managed by Qinetiq – a global defence and security company – which describes the area as a “unique right of way which requires both caution and specialist knowledge to negotiate safely”.
However, the route is not for vehicles, and people are advised to only walk there accompanied by a guide who knows the mudflats.
According to parish council records, 100 people have died on The Broomway, with the last known death in 1919.
