About
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.

Phenomenal views. No fence, so be careful, but if you are adventurous lay down and peek over the side.

You can get there via bicycle, van tour, or horse driven carriage. We rode bikes, and though we made it, for those not in great shape it can be challenging. I would recommend the electric bikes for those concerned with physical condition, or those who just want an enjoyable ride.

Breathtaking views, we were able to get amazing photos. We went early in the morning which avoided the crowds on the walk up and down. Nice selection of shops at the base we met a very kind lady who had a knitting and painting shop, she was lovely to our son and gave him discounts of his purchases which made his day.
They badly need more catering places for the tourists at lunch time and parking for all the buses.

This old fort is probably the highlight of a visit to Inis Mor. However, it is a fairly rugged climb to get up there, and a few euros to do it. The path up to it is gravel for about half way. But, the next part is rugged rocks, but doable. I used a walking pole, and was glad I had it. The views are breath taking, and the edge of the cliff is quite an adrenaline rush. Pictures don't do it justice. This old stone structure is dated back to 1100 BC! How in the world they could do this is unbelievable. As one might expect, it is very windy, and approaching the cliff's edge is very risky, although many people were doing it. A great and thrilling experience.

It is a 30 minute roundtrip hike to the top. There is a carpark at the bottom where you can also lock your bike (which is a nice way to get around the island if you are day-tripping it or doing an overnight). The views are worth the hike! If you are going on a day trip, just make sure you have a nice day before going.

Stunning. We cycled and then climbed up with our 3 children, 3,7 and 10 years old. They all found it enjoyable. Carried the smallest child part of the way. The climb took us around 15 to 20minutes. Lady at the desk and lady in the gift shop were very friendly. Toilets in clean condition.

It's a hike, don't get me wrong, but it's definitely worth it in the end! The views are spectacular, way better than Cliffs of Moher in my opinion. Must be physically fit and able to walk 1 kilometer on sometimes uneven surfaces. I visited on a sunny day, but if the ground is wet I imagine it's even more tricky to do this walk. This whole island is amazing and definitely worth the ferry ride over. Plan to spend the entire day, or at least as long as the ferry runs, to see it all. I've never seen another landscape quite like this one, it amazes me that people even live on this island!

Dun Aonghasa is breathtaking, we spent two nights on innis mor in April and it was quite and peaceful. The climb up to Dun Aonghasa isn’t challenging for any able bodied person but care is needed on a wet day. My advice is stay a night, rent a bike and take in the island at your ease, you are on holidays after all.

Stunning fort on top of the cliff with amazing views. Interpretative Centre had lots of info and very good staff.
We had an archaeological query they didn't have an answer to but when we got back from the fort we found they had researched and had a printout ready with the info we were looking for.
Might not have been possible to do this at busier times but they showed a real interest and dedication to the job. Really excellent.
Great wildlife and wildflowers around too, worth keeping an eye out on the walk up to the fort and the staff were well informed about this too.

I loved this part of our tour, we were dropped off for 2 hours here and it was a gorgeous day.

The walk is up hill, I'm not as fit as I used to be and I found it was grand once you take your time, some of the stones are worn down from everyone walking up and they're now smooth and slippy, we did see two men who must of fallen, their legs were cut pretty bad.

There is no barrier at the top but the views are stunning.

Definitely worth while

Exhilarating from a historical perspective. Awesome views over the cliffs. A wonderful day spent on the aran islands. Very professional tour guide. Our group ranging from age 8-72 traversed the trail well. Watch your step and take it slow.
