Park write-up

Bannau Brycheiniog (Brecon Beacons)

Wales Wales · Europe · Visited 12 December 2025 · Established 1957

Bannau Brycheiniog (ban-eye bruck-ay-nee-og, meaning "the Peaks of Brychan's Kingdom") officially reclaimed its Welsh name in 2023, following Eryri's (Snowdonia's) lead the year before. People still call it the Brecon Beacons, and that's fine, but the Welsh name is worth learning to respect local wishes.

This is one of my favourite UK parks. It's close enough to home that I've visited many times, and it's never once felt like I've exhausted it. The park covers 520 square miles of south Wales, containing the highest mountains in southern Britain, and sits less than three hours from London. That accessibility is part of its appeal. You can be on a summit by lunchtime.

Pen y Fan

Pen y Fan at 886 metres is the headline, and I've climbed it many times from many different routes. It's an excellent first serious mountain for beginners. The paths are well established the whole way up, and from most approaches you can see the summit for much of the climb, which takes the navigation anxiety out of it. The sense of achievement at the top is real, especially if it's your first time above 800 metres.

But a word of caution: dress properly and always carry a backpack with spare layers. The weather in the Bannau changes constantly, even in peak summer. I've set off in sunshine and been in near-zero visibility within an hour. Wind, rain, and sudden temperature drops are standard, and the exposed ridgeline between Corn Du and Pen y Fan offers no shelter whatsoever. People underestimate this mountain because the path is good. Don't be one of them.

The ultramarathon

I signed up for an ultramarathon here in August and was met with rain the entire time. Over 50 kilometres and over 2,000 metres of elevation gain, finished in seven hours. I somehow made the top 20, which I still can't quite explain, because I had never run over 30 kilometres before, and certainly not with that kind of vertical. It was the most physically demanding thing I've done, and for most of the second half it was a battle with my own head rather than my legs.

Beyond the peaks

The Bannau is more than its mountains. The park contains a UNESCO Geopark at Forest Fawr, with waterfalls, limestone pavements, and caves. The Brecon and Monmouthshire Canal offers flat, peaceful walking and cycling. The market town of Brecon itself is a good base with enough pubs, shops, and cafés to keep you comfortable between hikes. And the park is one of only three International Dark Sky Reserves in England and Wales, which means the stargazing on a clear night is exceptional.

Who it's for

Bannau Brycheiniog is one of the most accessible mountain parks in Britain. The peaks are high enough to feel like proper mountains, the trails are clear enough to give beginners confidence, and the variety of landscape (moorland, waterfalls, canals, caves, dark skies) means there's far more to do than just bag summits. It's the park I'd recommend to anyone who wants to start taking mountains seriously without travelling to the far north. Just pack a spare jacket. You'll need it.
