Cadsonbury

The Iron Age hillfort at Cadsonbury sits above Callington with views that stretch across the moorland towards Kit Hill. It's not much to look at on first glance - just earthworks and bumps in a field - but spend ten minutes walking the perimeter and the defensive ditches become properly impressive. Someone built something serious here, maybe 2,500 years ago, and the landscape still shows why they chose this spot.

The site itself is free and accessible on foot, with no formal facilities or visitor centre. Bring decent boots because the ground gets boggy in places, and you'll want an hour to really explore it without rushing. The views alone make the walk worthwhile, especially on a clear day when you can see for miles across Cornwall.

It's less crowded than the famous Iron Age sites further south, which means you get peace and quiet to think about what life would have been like up here in the centuries before the Romans. That's the draw for history buffs - real archaeology without the visitor-centre crowds. Casual walkers will appreciate the moorland setting; young kids might find it a bit abstract unless they're already into ancient forts.

Callington is the nearest proper town if you need supplies or a cup of tea afterwards. Sunnyside Eco Glamping sits just under three miles away, making Cadsonbury a natural add-on to a wider moorland walk when you're staying in the area. Not essential, but genuinely interesting if you're already in this part of Cornwall.
