Mewslade Quarry Cave - Left Entrance

Three limestone arches punch through the cliff face at Mewslade Bay, and the leftmost one opens into a proper cave system that'll have you scrambling through narrow passages on hands and knees. This isn't your typical tourist cave with handrails and lighting - it's wild, muddy, and absolutely brilliant for anyone who fancies a bit of underground exploration.

Proper cavers will love the tight squeezes and multiple chambers that branch off the main passage. The entrance sits right on the beach, so timing matters - you'll want to visit at low tide when the cave mouth isn't swamped by waves. Bring a decent torch, spare batteries, and clothes you don't mind getting filthy.

Families with older kids who aren't fazed by getting dirty will find this a cracking adventure, though little ones might find the tight spots a bit much. The cave stays cool year-round, making it a good rainy day option during a Gower holiday.

Reaching Mewslade Bay from the clifftop car park involves a steep scramble down rough paths - not one for anyone with mobility issues. If you're staying at one of the nearby sites like Pitton Cross or Hillend Camping Park, it's an easy drive to add some underground adventure to your coastal break. Just don't expect to stay clean.
