The Royal Welsh Regimental Museum

The regimental museum sits in Brecon's town centre, a proper slice of Welsh military history housed in what used to be the barracks. It's a small but serious collection - uniforms, weapons, medals, and the sort of kit that tells you exactly what soldiers carried into battle over the past couple of centuries. You'll walk through displays covering everything from the Napoleonic Wars through to more recent campaigns, with enough detail to keep history buffs occupied for a good hour or so.

Families with older kids will find it engaging rather than overwhelming. Younger children might lose interest once they've had a look at the swords and cannons, so it's not a rainy-day resort for the under-eights. The museum's intimate scale means you're not trudging through endless corridors - it's focused and manageable.

Brecon itself is brilliant for a holiday base, surrounded by the Brecon Beacons, so you're never far from proper walking country. Cefn Cantref Campsite sits just over a mile away, making this an easy detour when you're pitching up. Pencelli Castle, a couple of miles further out, and Woodland Park Glamping up at four miles all put you within easy reach. The town has enough cafes and pubs to make it worth staying for lunch after a museum visit, and there's genuine scenery on the doorstep. A morning here, then out into the hills - that's how to do it properly.
