The ledge narrows towards the back and provides a perfect home to aquatic life. Swim around the tip of the island to where a spectacular collection of giant boulders carpeted in dead mans fingers are propped up against the side of the island.

The Puffing Holes (Aran Island)

Description: This dive is an underwater chasm in the limestone which extends for at least 120 m and is closed at one end. Although they cannot be seen from underwater, it is believed that the cave eventually leads to the puffing holes which are visible high on the shore above. Divers should not venture more than 10 or 15 m into the entrance without advanced training and planning and using appropriate cave diving techniques. Under the right conditions this dive is exhilarating and unrivalled, but is definitely not one for the faint hearted.
