Ysgwydd Hwch

There's a pull-off moment when you first spot Ysgwydd Hwch rising above the moorland south of Brecon. It's a proper hill walk rather than a casual stroll - the kind that leaves you genuinely knackered but grinning when you reach the top. The name means Sow's Back in Welsh, which makes sense once you see the ridge running along it.

This one's for walkers who know what they're doing. The paths aren't waymarked to death, and the terrain shifts between boggy sections and rocky scrambling depending on which approach you take. Allow a good two to three hours for the round trip from any sensible starting point, longer if you're stopping constantly for photographs. The views back towards Brecon and across the Black Mountains are the real draw here - that sweep of Powys moorland doesn't disappoint on a clear day.

Worth fitting in if you're based at one of the nearby camps like Bryndu Caravan and Camping or Great House Farm's pods - both are within striking distance. The peak itself is free, naturally. Best visited outside peak holiday season if you prefer solitude; the summer school holidays can bring coaches of day-trippers to the area. Families with younger kids might find the exposed sections a bit much, but confident teenagers will enjoy the scramble. Take water and proper boots. The weather here changes on you fast.
