Withernsea Beach is part of a long strip of sand and shingle that stretches for miles in either direction. The recently rebuilt promenade includes a dramatic facsimile castle entrance with access via a slipway. Slightly inland, there is a 39 m (127 ft) tall lighthouse which now houses a museum and RNLI exhibition. The beach holds a Blue Flag Award, meaning its water quality is excellent and it is also Marine Conservation Society Recommended. Activities that take place here include sailing, wind surfing, kayaking and canoeing. Spurn National Nature Reserve, a Site of Special Scientific Interest, is located nearby.
