Sandy Haven is a secluded bay, near to the oil refineries of Milford Haven. Access is along a single track lane from the village of Herbrandston. There is a small, free car park (7 foot height restriction) on grass adjacent to the coast path and overlooking the beach near the end of the lane. There are two picnic tables here and a small caravan site.
The narrow lane continues to a slipway onto Sandy Haven Pill which is sandy with a small stream. Parking is possible on the sand here. The stream can be crossed via stepping stones, which are usable for approximately 2½ hours either side of low tide. If the tide is high it's a 4 mile detour to get to the other side. On the western side is another slipway and parking is also possible here on the shingle.
Sandy Haven beach is sand and seaweed strewn sandstone rocks. At low tide there is plenty of sand, but at high tide the beach is mostly covered. From the car park access to the beach is a short walk down over the rocks, or walk 150 yards eastwards along the coast path and there are steps down onto the sand. Swimming is generally safe here, and rocks provide plenty of sheltered areas for sunbathing.
