Red Dog chambered cairn

Walking out to Red Dog feels like proper archaeological detective work. This chambered cairn sits on the outskirts of Ardgay in the Highlands, a Bronze Age tomb that's been here for thousands of years, and you can actually get inside to see the stone chamber itself - that's the real draw. The structure's weathered considerably, but the internal passage and burial chamber are still recognisable, which beats standing outside a roped-off site trying to imagine what went on.

It's free to visit and open all hours since it's an ancient monument with no facilities whatsoever. You'll need about forty minutes maximum, including the walk in from the nearest road. The path isn't exactly signposted to perfection, so best bring a map or do your homework beforehand.

History buffs and anyone into Bronze Age Scotland will find it genuinely worthwhile. Families with young children might find it a bit underwhelming - it's just stones, after all, and there's nowhere to sit or shelter if the weather turns. The setting's pleasant enough, though you won't get views that'll take your breath away.

If you're based at Ardgay Glamping nearby, this makes a decent half-day outing to break up a longer park holiday. It's the sort of thing that works well paired with exploring the Dornoch Firth area, rather than being a destination in itself. Worth the detour if archaeology actually interests you rather than because you feel you ought to tick it off.
