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.

Had dreamed of going here since my last visit to Ireland in 2013, finally made it this trip. Took the ferry over from Galway and rented bikes. In my opinion renting a bike is the way to go. You can travel at your own pace and see what you want. We went first to the Black Fort and had it... More

The Dun Aonghasa fort is an incredible site to visit, the history is well explained, and it is easy to get to once you are ont he island. That's all secondary compared to the fort itself though: it is an imposing structure at the edge of the cliffs. The views are spectacular, the path up is a great walk, and... More

It was a nice and quiet experience. When we arrived there, the place was almost empty, so not so many tourists. It is so peaceful in this conditions....you can hear the waves and feel the nature so close to you....

We visited this attraction as a family and found it very friendly and easy to get to as a family , the views are spectacular and you can see the whole of Galway and Clare and the cliffs of Moher on a clear day. The hotel gave us a fee pass which made access free which is great for a... More

This was one of the most breathtaking sights I've ever seen in real life. The prehistoric fort is something to behold, but my favourite part was the view of the sea and cliffs. (I was fortunate to have been there on a pleasant, sunny day.) Unlike the Cliffs of Moher, there are no railings - you can go as close... More

Great hike, great views, must see. If you don't like the weather, wait five minutes. When you come out, visit the nice lady in the third shop on the left, she has hand knit local sweaters.

Like prehistoric sites, panoramic views, nature and hiking? Then you should head to Dun Aonghasa! It's only a 30 minute cycle from the harbour, pretty flat all the way, but take the High Road back, it's uphill for the first 5-10 minutes but it's downhill all the back to Kilronan. It's good to know that if you spend a night... More

I have done a bit of travelling, seen a lot of attractions but this is by the far the best thing I have ever seen, it is like walking upto the of the end of the world. Cannot recommend this place highly enough. Will need decent shoes, some water and a great camera, slight trek upto it but well worth... More
