Twyn y Gaer

The walk up Twyn y Gaer doesn't mess about. This steep little peak sits just outside Brecon and rewards you with proper views across the Brecon Beacons - the sort of panorama that makes the huffing and puffing worthwhile. It's not a long hike, but it's sharp enough that you'll feel like you've earned your lunch afterwards.

What you get at the top is a trig point, open moorland, and on a clear day, sight lines that stretch for miles. The peak itself isn't dramatic - no dramatic escarpments or anything theatrical - but that's partly the appeal. It feels like proper walking country rather than a tourist trap. Walkers and fell runners will get genuine satisfaction from this one. Families with older kids who can handle a brisk climb will do well here. If your children need a gentle stroll with minimal elevation gain, look elsewhere.

There's no visitor facility, no café, no charges. Just park sensibly near the trailhead and go. Allow a couple of hours including the summit time, though fit walkers will crack it faster. Spring and autumn work best - summer can see the moorland get a bit hazy, and winter requires proper hill sense.

Stay at one of the nearby glamping spots - Aber Glamping in the Brecon Beacons is only 3.5 miles away - and you've got this as part of a proper walking holiday across the range. Cefn Cantref Campsite is even closer at 3.4 miles. Base yourself there and tackle several peaks across a few days.
