Cefn y Llethr Hir

The walk up Cefn y Llethr Hir rewards you with proper views across the Powys valleys - the sort of panorama that justifies a day in mid-Wales rather than somewhere more obvious. It's not a bruising scramble; the ascent is steady and manageable, which means families with older kids and regular walkers both get something out of it.

You're looking at a round trip of a couple of hours from the nearest approach, depending on fitness and how long you linger at the top. The peak itself is open moorland - nothing dramatic like you'd find further north, but there's a real sense of being away from things. On clear days you can pick out the ridge lines running east and west. The ground underfoot is typical Welsh moorland: boggy in places, firm in others, so decent boots are non-negotiable.

Neath is your nearest proper town for supplies and a decent pub afterwards, though it's a fair drive from the trailhead. What makes this work brilliantly is pairing it with a longer stay in the area - Willow Springs Campsite and Four Falls Glamping both sit within five or six miles, so you can tackle Cefn y Llethr Hir as part of a proper walking break rather than a rushed detour.

It's free to access and there are no opening hours to worry about - just check the weather before you head out. Bog season (late autumn through spring) makes it wetter underfoot, but that's about your only real constraint. Well worth the morning if you're in Powys anyway.
