Backed by a sea wall, activities here include fishing, diving and snorkelling, sailing, swimming and wind surfing. Pagham Harbour, also to the east, is a nature reserve and nature lovers will find many bird, butterfly and plant species here. The beach itself is Marine Conservation Society Recommended.
