Where it is

The circle shows the general area, not the exact start. Use the directions link below to get to the car park itself. Contours and paths shown are OpenTopoMap, drawn from OpenStreetMap data.

The route

Boardwalks cross the dunes to the beach, which runs north and south. Flat but soft going in the dunes.

Worth knowing

  • Part of the beach is a long-established naturist area and is signed as such.
  • The dune slacks hold rare plants including petalwort and dune helleborine.
  • Sand lizards were reintroduced here and are occasionally seen on warm days.

What you’ll see

Mobile dunes, slack pools and their flora, and a very long empty beach.

Background

The reserve protects one of the few remaining actively mobile dune systems in Britain, where sand still moves freely.
