Dun Aonghasa, Inishmore
(4.8/5 based on 900+ reviews on the web)
Perched atop a cliff, Dun Aonghasa represents the most popular of the prehistoric forts on the Aran Islands. Walk from the nearby museum up to the fort and enjoy panoramic views from the 100 m (328 ft) cliff. Marvel at the three terraced walls and intricate defense system of stones called Chevaux de Frise. Archeological studies have revealed that the fort was built in the Iron Age, possibly as far back as 1100 BCE, though the triple-wall defenses were likely added around 500 BCE. The fort is named for a pre-Christian god or mythical king, Aonghus mac Umhor. Explore the history of this ancient monument, but take care when walking and climbing around the site, especially with children, as it can be slippery. See Dun Aonghasa and all Inishmore has to offer by arranging your trip with our Inishmore trip generator.

  • After passing the convenience store and the ticket office, you can get there with a stony path that is good to deal with some good walking shoes because sometimes there are some rough stones and is easy to slip out of those wet if you don't have shoes with rubber sole; After the climb we enter the first stone circle, here you can get directly to the edge of the cliff and lie face down on the cliff and watch the waves crash on the rocks below; the scenery is magnificent, with sweeping views over the island and the West Coast, don't miss it if you come to visit these islands; could be very dangerous if you are afraid of heights.

  • Great visit! Lots of well put together historical info on the site at visitors centre Climb is challenging. They say "easy" with a "moderate" 100m at end. I would be a bit circumspect about that. The gravel path is well maintained but a steady incline, the last 100m is challenging for the reason that the surface is quite uneven - you need to keep wits about you! But a good site to visit with great photo opportunities!
  • For those who are fascinated by prehistoric sites, as I am, this is a must-see if you visit Ireland. While there is not much known, and thus to tell, in the small museum, the sheer natural beauty of the site alone is worth the visit. It was easy to let my imagination run free, standing there among the ruins looking out over the sea. We also had a wonderful lunch in the cosy little cafe along the main road where the tour buses drop off visitors. The staff were very friendly and chatted with us, while serving delicious food (I recommend the Guiness stew).
  • Amazing place. Not easy to get to.
  • It must be worth visiting. On The way from the port to this place, we also enjoyed the pastoral scene. I recommend to walk from the port if the weather is good.
  • Pretty nice view from up there. Not sure it's worth spending the day there though.
