Braunton Burrows (see Figure 7.1 for general location) is one of the three largest dune systems on the west coast of Britain. The dunes extend about 6.5 km southwards from Saunton Down across the lower valley of the rivers Taw and Torridge. The dune belt is about 1.3 km wide throughout this length and is fronted by a sand beach, which, in places, exceeds 1 km in width at low tides. At the north end, the structure of the dune system is influenced by the hills of Down End, at its southern end by the Taw–Torridge estuary. Individual dune ridges, which sometimes exceed 30 m OD, are best developed in the central part of the system. Although wartime use did extensive damage, this proved to be short-lived, and the dune complex remains quite outstanding (Figure 7.9).
