The Wormhole (Poll na bPeist).
I took this video when I was there because I was completely blown away by the landscape, the color, the variations of texture, everything. It’s an amazing part of the island that not many people go to see because it’s rather difficult to get to. But if you’re visiting Inis mor and are able to take a walk off the beaten path, go see the Wormhole. (More info on how to get there in my blog post on the Aran Islands Blog).
