Sunadale, dun site

The ruins of an Iron Age fort sit on a windswept hillside near Campbeltown, commanding views across to Davaar Island. Sunadale is what archaeologists call a dun - a small fortified settlement that would have housed a handful of families a couple of thousand years ago. What you actually see is a circular stone rampart, partially collapsed but still substantial enough to understand the layout. The site's positioned on a slight rise with decent sightlines, which tells you everything about why someone picked this spot.

This is strictly for archaeology enthusiasts and serious walkers. You won't find interpretation boards or a visitor centre - just the remains and the landscape. The walk from the road is straightforward enough, though the final approach can be boggy depending on recent weather. Allow an hour return journey if you're taking your time to properly examine the stonework and absorb the location.

If you're camping at Carradale Bay Holiday Park just down the coast, Sunadale makes for a rewarding afternoon detour rather than a main event. The Kintyre peninsula has several duns and ancient sites scattered about, so dedicated history-heads could string together a proper archaeological afternoon. Entry's free, obviously - there's nothing here to charge for. Best visited in decent weather when the views justify the trek. Midges can be vicious in summer, so consider an early spring or autumn visit instead.
