These beaches lie south of Rhossili, on the far western end of the Gower peninsula. At low tide it's possible to walk between the two, but at high tide the beaches are mostly covered.
Fall Bay (above) is the more westerly of the two, lying east of Tears Point and is backed by low limestone cliffs. Access from the coastal path is down a steep-sided valley followed by a short, but steep rocky bit. Mewslade is bounded to the east by Thurba Head and backed by high limestone ciffs. Access from the coastal path is a good path down a steep-sided valley, leading onto rocks at the back of the beach. There are numerous small caves on the beach, but the more ambitious explorer may like to try Mewslade Quarry Cave (which has a very small entrance) and can be found by walking back to the coastal path, taking the path directly ahead (signposted 'Pitton') and heading off to the left where this path descends slightly. The cave is just about 30 yards away in a rock face.
The nearest parking is an attended car park at Rhossili, which has good facilities including toilets, cafes and ice-cream shops and a surf shop.
Both beaches are popular surf spots, at their best around low to mid-tide with a good swell. They tend to be flat in summer, but can get busy when they work. Submerged rocks and rips can be a hazard, and these beaches are not for beginners. Dogs are allowed at all times.
Warning : Adders are common around this part of Gower; take care if walking off the main paths.
