Sandy Haven is a secluded bay on the north side of the Milford Haven. A narrow lane from the village of Herbrandston leads to a small, free car park (7 foot height restriction) overlooking the beach and adjacent to the coast path. 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, but parking on the sand is not allowed. The stream can be crossed for approximately 3 hours either side of low tide, otherwise it's a 4 mile detour along roads to get to the other side. On the western side is another slipway onto the shore.
Sandy Haven beach is a mix of sand, rocks and plenty of rockpools, the sand at the top of the beach being coarse and gravelly. The beach is mostly covered at high tide. From the car park access to the beach is a short walk down over the rocks, or there are steps down onto the shore approximately 150 yards eastwards along the coastal path. Swimming is generally safe here, and rocks provide plenty of sheltered areas for sunbathing. Dogs are allowed at all times.
On the eastern side of the beach a footpath leads back to Herbrandston village.
