Dun Aonghasa, Inishmore

4.7
#1 of 14 in Things to do in Inishmore
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.

  • Beautiful walk to the wormhole & then up to the fort. Wear sturdy shoes & bring a jacket - it was brisk up by the cliff in March!  more »
  • Visited with family in Aug 17. Trecked from the Serpents Liar - has to be seen also!!- to Dun Aonghasa and it's a fantastic walk. Not for anyone with walking difficulties but well worth the effort. On...  more »
  • Breathtaking scenes. It was very windy when we went, but was a great experience. The sights were amazing and the landscape is very beautiful, I would go again but dress warmly.  more »

  • Stunning views on a great day, one of the best attractions in Ireland (I've seen most). Can be a bit pricey to get there by cab from the pier in Kilronan (€15 per person as of 2018) so you might want to check this first or consider renting a bike. Entry price to the site is very reasonable though. Can be done via the lunchtime ferry crossing but limits you in doing anything else if you need to catch the 5pm return crossing. Best plan if you want to see more is rent a bike and get over there early.
  • Spent an enjoyable afternoon here on a sunny day and learned all about the history from the tour guide. The staff were extremely helpful and friendly. It's a bit of a walk from the base so be sure to travel light and bring some water. There's not a massive amount to actually see but it's a stunning place to take in the view and do yourself a favour and hang out for a while... We stayed for a good while and eventually managed to get the whole place to ourselves for a few minutes. So peaceful looking out over the ocean with no one else around.
  • Lovely place, the price is totally good for what you see. Awesome landscapes. (The staff should be more friendly at the reception)
  • Gorgeous. The highlight of Inishmore, and for good reason. Definitely worth the bike ride, and get here as early as possible, preferably before the day trippers that take the 10am ferry here.
  • Very interesting. Some good info at the entrance and not too far a walk from the road. We went late and there was noone else there so it was really special.
