The long undercliff walk from Black Rock to Saltdean was built between 1930 & 1935 as part of the sea defences to reduce the erosion of the chalk cliffs. The Gap is a natural break in the cliffs allowing access to the village.
Beach & Sea
The beach is backed by chalk cliffs and a life guard service operates in summer. There are rock pools to explore and the remains of tracks for Magnus Volk’s ‘Daddy Longlegs’ Railway can be seen.
