For centuries, the Broomway was the only way to access Foulness Island on foot. Recorded as early as 1419, the footpath runs for about 6 miles through vast sand flats and mud flats that look deceptively easy to navigate in good weather, but that can prove deadly in less than ideal conditions. Named after the hundreds of “brooms” – bundles of twigs attached to short poles – which once marked the path, the Broomway is now outlined by wooden poles that are easy to miss in fog and heavy rain. And getting lost in the treacherous sand flats can be deadly, for a number of reasons.
