About MarloesSands, Wales:

Marloes Sands is anapprox. 1.5 kilometres (0.93 mi) long remote sandy beach inPembrokeshire, Wales, near the village of Marloes.

It's broadly curved and surrounded by cliffs. Walking on the beachgives great views of Skokholm Island and Gateholm Island.


The beach is located SWfrom the Marloes village and there is a National Trust car-park nearby(charge per day or free for National Trust members).
There is a track that leads from the main road to the beach.

There is a disused World War II Royal Air Force airfield RAF Dale,above the south east cliffs of the beach.

There are approximately three accesses to the beach which become veryuseful if you get caught by the tide coming in.

Besides the main access from Runwayskiln there is also an access to thenorth, near Gateholm Island, that requires some scrambling over therocks and another access to the south that has steps leading to themidsection of the beach.
