Dun na Cuaiche

The ruins of Dun na Cuaiche sit on a rocky outcrop above Loch Fyne, a twenty-minute walk from Inveraray. It's a proper scramble up to the summit - nothing technical, but your legs will know about it. What you get at the top is a broch, or at least what remains of one: a circular stone tower from the Iron Age, maybe 2,000 years old. The walls are tumbled and mossy now, but you can still make out the structure, the inner chamber, even tool marks on some of the stones.

Historyheads will find this absorbing. The views across Loch Fyne are genuine payoff, not just nice scenery but genuinely panoramic. On a clear day you're looking at proper Highland landscape. Families with older children might manage it - the walk is steep but short, and kids often love scrambling about ruins without barriers. Younger ones will likely get bored waiting at the top while adults squint at stones.

It's free and there are no opening hours - you're accessing a hill. Allow two hours return if you're fit, three if you're taking it easy and actually looking at things. The Argyll Caravan Park sits just 3.4 miles away in Inveraray, making this a decent half-day outing alongside the town itself. Worth it if you're already in the area and don't mind a bit of uphill graft. If you're after flat archaeology, this isn't your spot.
