Henrhyd Falls

The waterfall itself is a proper sight - Wales's highest single-drop cascade thundering down 90 metres into a plunge pool that's genuinely dramatic. You walk through a cave behind the water, which sounds gimmicky but actually works. The spray hits you hard enough that waterproofs aren't optional, even on dry days.

It's about a 20-minute walk from the car park up a steep valley, so this isn't a five-minute photo stop. Families with primary-age kids will manage fine; toddlers and the seriously unfit might find it wearing. Walkers and photographers get the most out of it. The light changes everything - morning sun from one angle, afternoon from another. Go midweek if possible; weekends bring crowds that clutter the shots.

Free to visit, no facilities at the site itself, so grab supplies before you head up. Allow a solid hour and a half, longer if you're trying different vantage points. The ground stays boggy even days after rain, so proper boots beat trainers.

It fits well with a Beacons holiday. You're close enough to both Brecon Beacons Camping & Caravan Park and Four Falls Glamping to make it a morning mission before tackling longer hikes elsewhere in the range. Swansea's near enough for supplies but the falls themselves sit deep in proper mountain country. Worth the drive.
