Twyn Dylluan-ddu

The walk up Twyn Dylluan-ddu isn't long, but it's properly steep in places. You're looking at a modest peak in the Brecon Beacons, reached easily enough from Brecon itself - under five miles away if you're heading out for the afternoon. The summit view across the Powys moorland isn't dramatic in the way a Welsh 3000-footer might be, but there's something satisfying about standing up there with minimal fuss.

This is walker territory, plain and simple. Not families with small children - the climb's too relentless for that - but perfectly decent for anyone wanting a leg-stretch without committing to eight hours. Allow two hours return if you're steady on your feet, longer if you're taking it easy. Free, obviously. You just park and go.

What makes it work as part of a Beacons trip is the lack of crowds. Everyone's queuing for Pen y Fan or Corn Du, and you're up here with maybe a handful of others. The moorland itself is the appeal - open ground, decent views eastward, and you can see why people come to this corner of Mid Wales repeatedly.

Based near Brecon - Cefn Cantref Campsite and Aber Glamping are both within five or six miles - it's the sort of walk you do on your second morning when you've still got energy but want something straightforward. Not a destination peak, but a proper bit of walking that earns its place in your itinerary.
