Owner description: 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.

OMG! Let yourself go and imagin the people who built this and lived here so many years ago. They accomplished much with little and the results have stood the test of time. It is awesome - you are at the edge of the Atlantic ocean and you can look across Inismor to Galway.

We visited Inishmor more to spend a day riding bikes than to see any sites, but we heard good things about Dun Aengus so we pedaled our way up. It's an easy/moderate 15 minute walk uphill and over rocks to get up to the site from the parking lots, but the views from the top of the cliffs are worth it. The sheer cliffs are similar to the Cliffs of Moher but you are able to walk, crawl, or wiggle your way right up to the edge and hang over the side. The scenery is magnificent and more than makes up for the fact that there's little of the old fort to see.

This place is fantastic!! It is quite a climb but definitely worth it. It is scary to look over the edge as there are no rails or walls to keep anyone from falling off. Glad we took the time to visit it.

This interesting ring fort is worth the effort to get to. It is a couple of miles from where the ferries let you off. There is a constant stream of tourists making their way toward the hill. Watch out for small tour buses, they go pretty fast and often catch walker/cyclists off guard.

The walk directly up the hill is extremely rocky and uneven so make sure you wear shoes that are good for rugged stoney terrain. I saw families with strollers trying to navigate through all these rocks, most opted to carry the strollers. The views walking up are awesome, take time to enjoy the view of the whole island and the surreal rocky landscape.

Make sure to read the info in the small visitor center to help you understand what you're seeing once you get up there. The inside of the fort is open and empty. Only one or two info signs are there to explain what you're looking at.

There are a few spots where you can see that something used to be there, but it's the rings of the fort itself that are the big draw here. There are staff members there and they were very friendly and answered all kinds of questions. They also did a good job keeping an eye on all the people that seem determined to creep up and peer over the edge. There is no railing so be careful and of course keep the kids close while up there.

There are places to get snacks, quick meals, and souvenirs at the base of the hill. There are also restrooms there. Know ahead of time, there is nothing like that up by the fort. So my words of wisdom are to hit the bathroom before you start your trek.

I thought better then the Cliffs of Moher! The cliffs are just as impressive and there are no walls or barriers so it is quite thrilling watching crazy people get close to the edge! The fort is well preserved. Read the description at the bottom in the office where you pay. There is about a 20 mins uphill walk to the fort and clifftops. This also offers a spectacular view of the whole island! We biked from the ferry on the low road up to the fort. Then had lunch 2 mins from the fort and cycled up to the lighthouse and then back to the ferry. This was one of the best days we spent in our 3 week trip to Ireland. This fort is not suitable for young children unless you are going to watch them carefully or for physically diabled.
