Mynydd Llangynidr

The walk up Mynydd Llangynidr rewards you with one of those views that makes the leg-burn worthwhile. It's a proper hill rather than a mountain - 600-odd metres - which means it's steep enough to feel like you've earned something without needing technical gear or a dawn start.

From the summit you get the Brecon Beacons rolling out in all directions, and on a clear day the visibility is genuinely impressive. The approach from Brecon itself takes about an hour, and the terrain is moorland underfoot - boggy in places, so decent boots matter. Families with older kids will manage it fine; younger ones might find it a slog.

It's free, obviously - it's a Welsh hill. No facilities at the top, so bring water and something to eat if you're planning to linger. The best time is late spring through early autumn when the weather's most predictable and the ground's least waterlogged.

If you're based at Cwmdu Campsite nearby, you've got a good base for tackling this alongside other Beacons walks. The hill doesn't require hours of your day, which makes it sensible for mixing with a broader park holiday. Head up in the morning, back by lunchtime, then explore Brecon town itself in the afternoon - the cafes and bookshops there are decent enough. The walk's worth doing, but don't expect solitude or dramatic scenery beyond what the whole region offers.
