Many of these "Bone Caves " are very culturally significant and extremely well documented, although they provide little interest to the sporting caver.
The caves are listed here in a roughly counter-clockwise direction from Rhossili in the west to the eastern extent of the limestone at Mumbles Head.
A drill hole for a Rawl bolt can be seen in the rock about a metre above the tiny entrance which can only be seen when you are right beside it.
Access is gained to the cave down a very tight rift (ladder needed).
The vast majority of these caves are active sea caves or are remnants of such located in the upper cliffs from times of higher sea levels.
