Caswell Bay is a very popular Gower beach due to its proximity to Swansea. The shore is fine sand flanked by limestone cliffs. It can get busy especially at high tide when there is not much beach available, but at low tide the width of the beach extends to about 700 yards. A P&D car park is located in the valley behind the beach, and behind this is the Bishops Wood nature reserve. Facilities at the beach include toilets, a cafe, beach shops and cold water showers. Dog restrictions apply from May to September inclusive and lifeguards patrol from the second week of May to the end of August.
It's a very popular surfing beach, surfable at any time, but mid to high tide is best. It's suitable for beginners, but can get very crowded. A rip current can occur on the west side in surf conditions and weever fish may be a problem at low tide.
