Tyn Green Castle

You'll spot Tyn Green Castle long before you reach it - a distinctive hilltop fortification rising from the rolling Powys landscape near Llandrindod Wells. It's not some grand medieval ruin; this is a modest Iron Age hill fort, the kind of place where Bronze Age people chose to build because the views told them everything they needed to know about approaching danger.

The walk up is straightforward enough, and once you're at the summit, you get proper 360-degree views across Mid Wales. On a clear day it's worth the effort. The earthworks themselves - those raised banks and ditches - are still visible if you know what you're looking at. History buffs will find it genuinely interesting; casual walkers might spend twenty minutes here before heading back down.

There's no visitor centre, no café, no interpretation boards. You're reading the landscape yourself, which some will love and others will find a bit underwhelming. Free to access, naturally - just find somewhere to park and walk.

If you're staying at one of the local caravan parks - Fforest Fields is closest at less than two miles - this makes a decent morning or afternoon outing. Pair it with a walk around Llandrindod Wells itself and you've got a solid day. It's not a destination in itself, but for anyone interested in Iron Age Britain or just wanting to get up high with decent views, it's worth the detour.
