Ha' Of Greenland, Broch site

You'll find yourself standing on a windswept Caithness hillside staring down at what's left of a 2000-year-old broch - basically a circular stone tower that Iron Age folk built without any mortar. The Ha' Of Greenland is properly atmospheric, though you need to manage expectations. There's no visitor centre, no interpretation boards, just the broken ring of stones and your imagination filling in the gaps.

What you're looking at are the foundations and lower walls of a structure that once stood maybe 40 feet high. Brochs are unique to Scotland, and this one sits in isolation with views that stretch across Caithness moorland. On a clear day it's rather special; on a grey one, which is most days, it feels genuinely eerie.

Walkers and archaeology enthusiasts will get the most from this. Families with young kids might find it disappointing - there's no path, no facilities, and you'll need a good map or GPS to locate it properly near Thurso. Allow an hour if you're combining it with a broader Highland jaunt, maybe less if the weather turns.

It's free, naturally, and genuinely wild. If you're staying at Little Croft Highlands nearby, it's worth the detour as part of a longer day exploring Caithness archaeology. Just don't expect Skara Brae levels of access or explanation. This is raw Scotland - you either love that or you don't.
