An Dun, dun site

An Dun sits on a rocky outcrop overlooking Loch Fyne, a proper Iron Age fort that's been weathered by centuries but still commands the landscape like it means business. The site itself is fairly sparse - you're looking at ramparts, the ghost of ancient walls, and a lot of overgrown terrain - but the views across the loch are worth the scramble up.

It's the kind of place that works best if you're into archaeology or Scottish history. Casual visitors might find themselves here for twenty minutes, wondering what they're actually looking at. Parents with restless kids should probably give it a miss unless the youngsters are the sort who get excited about Iron Age settlements and don't mind rough ground underfoot.

There's no visitor facility, no interpretive boards that I could find, and no entrance fee because there's no formal entrance to speak of. You just rock up and explore. Allow an hour if you want to poke around properly and take in the views. Early autumn is lovely - the midges thin out and the light on the loch is golden.

If you're staying at Argyll Caravan Park or Stucreoch, both just under three miles away, An Dun makes a reasonable half-day outing combined with a walk around Inveraray itself. It's worth doing if you're already in the area and keen on Iron Age forts, but don't plan a trip around it alone. The real draw is the landscape and the fact you're standing where people stood two thousand years ago.
