Blind Sound Cave

Explorer Tom Dún Aonghasa is the big one, the famous one, the one your nan told you about. It sits on Inis Mór, right at the edge of a 100-metre-high cliff. That is serious height, lads. It is a prehistoric hill fort, one of several on the Aran Islands, but this is the best-known. People call it Dun Aengus, but the real name is Dún Aonghasa, and it matters. It is a huge tourist attraction, sure, but it is also a massive archaeological site. You see the old walls, the ramparts, the sheer drop. It makes you feel small and smart at the same time. The stone is weathered, ancient, and full of stories. You might see other tourists, or you might just see the Atlantic doing its thing. It is a bit of a climb to get there, but worth every sore muscle. Stand on the edge, take a photo, and try not to drop your phone. The view is legendary, the history is deep, and the wind will probably steal your hat. It is a proper Irish experience, no shortcuts involved.

Explorer Tom The Fir Bolg: Dún Aonghasa has a mighty stone fort and a name tied to their leader Aonghas. If I had a fort named after me, I would be unbearable about it for years. The real walls are impressive enough; the name brings the Fir Bolg tale along for the ride.

Explorer Tom Templenaneeve in Cill Éinne is hiding a treasure that is definitely a biscuit tin from 1952. It's just lower portions of walls now, which is very fashionable these days. Look for the ghost, then pretend you didn't.

Explorer Tom Monument in Kilmurvy is hiding a ridiculous smuggling story about contraband tea being swapped for stale biscuits. The rubble walling looks like it’s just giving up on the whole thing. Bring the dog, it’ll have opinions on the texture.

Explorer Tom Clochan na Carraige has two doorways and a window, so it's basically a luxury apartment from the 1700s. Bring a pen pal, they'll be jealous of the view.

Explorer Tom Dun Onaght has a massive rampart that looks like a stone donut. It's got two terraces and steps, which is fancy for a fairy fort. Find the wonkiest bit and send it to your group chat.
