The shore at Common Cliff consists mostly of wave-cut platforms of limestone, some shingle and tiny patches of sand. As with much of the coast here, low-tide reefs provide good surf. This particular reef is known as Pete's Reef, but the sharp rocks mean it's definitely not for beginners. The Wales coastal path runs a few hundred yards inland and is relatively level, but walkers who stick to this route are missing out on some spectacular scenery. A smaller (more interesting) path descends Blackhole Gut (just to the west) and skirts the beaches at the base of the cliffs. Immediately behind the beach is the Longhole Cliff nature reserve, named after Longhole Cave which can be found at Grid Ref : SS45128506. It's about 17 yards long and there are several other smaller caves in the vicinity.
The photo was taken at low tide, and shows the coastline looking towards Worm's Head (in the distance).
