Perched on a cliff overlooking the Atlantic Ocean, Dun Aonghasa is the largest of the prehistoric stone forts of the Aran Islands. It is enclosed by three massive dry-stone walls and a chevaux-de-frise consisting of blocks of limestone set vertically into the ground to deter attackers. Originally constructed c.1100BC, it was re-fortified around 700-800 AD. Excavations revealed significant evidence of prehistoric metalworking, as well as several burials. Visitor safety information: The fort is about 1km from the Visitors Centre and is approached over rising ground. The last section of the path is over rough, natural rock and care is needed, especially when descending. Boots or strong walking shoes are recommended. There is no fence or barrier at the edge of the cliff.

Semi circular fort built on a high cliff above the Ocean was built on this wild and desolate location on this island thousands of years ago. Inspires wonder and awe of the harshness of nature, and of human nature, given that these lengths were necessary...More

Stunning views surround your hike up to the Dun Aonghasa fort - but keep your eyes on your footing, as dampness makes the stones slippery. Fantastic placement of massive rocks baffle your mind, as you take it all in. We were battered about by the...More

I've been to this area twice and loved the view of the cliffs. I would warn that the trip all the way up to the fort is steep and involves very slippery rocks. But a great view can be seen even from outside the fort...More

While some suggested walking the island, the combination of tour vans & bicycles makes this challenging, not to mention one would need more than a day to cover it on foot. Instead, I joined a van tour operating as Noel Mahon's Luxury Tours which proved...More

A hike up to the cliff tops but worth it. The view was amazing and terrifying. Surprisingly no one falls to their deaths getting the ultimate selfie.
