Port a'Chaisteil, dun site

The ruins of an Iron Age dun sit on a rocky outcrop above the water near Tarbert, and frankly, it's the kind of place that rewards a bit of effort to find. Port a'Chaisteil isn't sign-posted like a major attraction - you'll need to ask locally or do some map work - but that's part of the appeal. What you get is a genuine archaeological site where you can stand among the stone walls and actually imagine life two thousand years ago, with the loch stretching out below.

It's a modest site in terms of visible remains, so this isn't somewhere you'll spend hours wandering around. An hour, maybe ninety minutes if you're the type to sit and soak up the atmosphere. The real draw is the walk itself and the view across to the Tarbert peninsula. History buffs will get more from it than casual visitors - understanding what you're looking at requires some background knowledge, so coming armed with a bit of research makes all the difference.

The site is accessible year-round and free, which is brilliant. You'll need reasonable footwear and a head for heights if the outcrop exposure bothers you. If you're staying at Killegruer Caravan Site, just five miles away, this makes a proper morning or afternoon outing without committing to anything too strenuous. Combine it with a walk along the Tarbert waterfront or a visit to the nearby villages and you've got a solid day that works whether you're keen on archaeology or just after a bit of fresh air and a quieter corner of Argyll.
