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.

If you are wowed by standing on a huge cliff and looking out over the water or by staring at a 3,000-year old set of rocks that has remained in excellent condition to this day, you'll like Dun Aonghasa. If that doesn't excite you, it'll just be another day with a beautiful ocean view near a bunch of rocks that... More

This was a mystical experience, so quiet, with a distinct feeling of sharing the day with those who have gone before. Clear sky as in this picture, not sure I'd want to be there in one of the storms that can lash these islands. It was so much easier to get there from Galway than I expected. Allow time for... More

First the visitor center is awesome. Friendly people and nice, simple educational material about Dun Aonghasa. What an incredible walk up to the fort and although in the rain the visit was historical impactful. A must visit for all visiting Inis Mor

Most definitely worth a trip to the Aran Islands to see. Construction started thousands of years ago and the fort is made up of thousands of stones all quarried locally and placed by hand Be sure to bring a rain coat and some water ( you can buy water but is 2 Euros for less than 500 mls)

We spent the night on the island, so we were able to arrive before the crowds. The site is beautiful and the views from the 200-foot cliffs are amazing. Upon leaving, we ran into the hordes that had come across on the morning's ferry. The visit would not have been nearly as interesting with that size crowd.

Hands down one of the most impressive and beautiful places we have ever been to! Bike park and very small museum at the entrance. There are a few authentic looking shops next to the beginning of the walk uphill where you can buy Aran craft (knitted items mainly) and postcards. There is a bit of a walk uphill, and once... More

We took an open carriage ride (Martin Mulkerrin and Hopper, his black and white horse) right from the ferry dock out to the fort visitors’ center. Highly recommended if you don’t feel like bicycling and you want to hear fascinating and poignant stories of Inis Mor. Go into the fort visitors’ center for information and to pay a small fee...
