Pen Y Fan Walks – 4 Routes To The Summit

This is a guide to hiking Pen y Fan, the highest mountain in South Wales. In this article I explain all you need to know about the 4 best Pen y Fan routes.

IMPORTANT UPDATE FOR 2020 – construction at the Neuadd reservoirs makes getting to the start of the Beacons horseshoe trail a little trickier but it’s still possible!

Pen y Fan Walks

Let me start by explaining how to pronounce it! If you’re not from Wales you’d be mistaken into thinking that it’s pronounced penny fan. But that’s one sure way to get a chuckle from the locals.

Actually, you won’t go far wrong if you try pen-er-van. Right, now we have that sorted, let’s talk about hiking Pen y Fan.

At 886m Pen y Fan literally means the top peak and there are several routes that can take you to the top. Its the highest peak in the Brecon Beacons, so whichever way you take there’s definitely a decent amount of “up”. As such there is no easy route to the top. Some, however, are more straight forward than others.

Being born and bred in nearby Merthyr Tydfil I’ve hiked this mountain more times than I can remember, so let’s get stuck into the trail options!

Pen Y Fan Routes

1. The Easiest Route Up Pen y Fan – The Motorway

This trail is the easiest Pen y Fan walk from a navigational point of view, as there is a stone footpath all the way to the top. I call it the motorway route because, as you might have guessed, it’s the most popular.

The hike starts in Pont ar Daf car park which you may have seen on the news for being jam-packed with cars pre-lockdown!

At the southern end of the car park there is a kissing gate that takes you to a bridge that crosses the river. After crossing the bridge, a well made trail takes you up the mountain side.

As you get closer to the top you will see a peak that appears to be the summit but don’t be fooled, this is actually Corn du, the second highest peak in the Beacons.

To add an extra challenge to your Pen y Fan hike you can take the footpath that leads to this peak. But if you want to stick with the main objective, take the footpath that leads slightly to the right and around Corn du. Once on this footpath you have one final push to the top of Pen y Fan.

Did you know? The cairn on the summit was a Bronze Age burial chamber. Now it’s a popular spot to get out the camera and take that “I made it” selfie!

After enjoying the 360 degree views (weather permitting) it’s time to head back down the way you came up. Once in the car park you can enjoy a well deserved ice cream!

2. The Storey Arms Route – Military Route

  • Distance: 7.2 km round trip
  • Elevation gain: 530m
  • Pros: Includes the second highest peak of Corn du
  • Cons: A lot of up and down
  • Map: Brecon Beacons Explorer 12

This hike starts from Storey Arms car park. From the car park cross the road and head up the path to the left of the Storey Arms (as you look at it). A man made path will take you all the way to the top. This path has a steep start then descends for a while before reascending to reach the summit of Corn du.

From the top you can see Pen y Fan ahead of you on a well made trail. Follow this trail by descending Corn du first then continuing up to Pen y Fan. To return simply follow the path back down.

Make a loop of it? You can combine these first two hikes to make a slightly longer (7.6km) loop. Park in the Pont ar Daf car park and ascend the motorway route. After reaching the summit, return via Corn du, down to Storey Arms then follow the footpath alongside the road to return to the car park. Top job!

3. The Pen y Fan Horseshoe Ridge Route

  • Distance: 15.3km round trip
  • Elevation gain: 1620m
  • Pros: Includes the 4 table-top peaks that form the core of the Central Brecon Beacons
  • Cons: Hard to navigate in poor weather
  • Map: Brecon Beacons Explorer 12

This Pen y Fan hike is definitely a lot more involved and a little trickier to get to as it’s not on the main A470 road. However, the Brecon Beacons horseshoe ridge walk, as it is also known, is a great full day in the mountains.

The hike starts from the Neuadd Reservoir access road car park in Talybont. From the car park follow the road north towards the reservoir. The road ends and forks into two paths.

2020 Update: Both reservoirs have now been drained so are empty of water. There is also a lot of construction fencing surrounding the old lower Neuadd Reservoir, which makes the trail difficult to spot.

Take the path to the left. From here you can see the whole route in front of you as you’ll walk around this amazing glacial valley. The path ascends steeply up onto the ridge. Once on top the ridge again head north along ridge on well maintained paths to reach, first Corn Du and then Pen y Fan.

From Pen y Fan descend steeply (known as Jacobs Ladder) then reascend to Cribyn, the third highest peak. From Cribyn you have the option to descend and follow the path back to the car park or you can ascend the final peak, Fan y Big. Any ideas how to pronounce this one? I’ll give you a clue – it’s not fanny big!

After completing the final peak you will see the well made path that takes you parallel to the drained reservoir and then along the road, back to the car park. Time for a well earned sit down (but sadly no ice cream here).

Pen y Fan walks are always great days in the Welsh countryside but there are lots of other walking options in the Brecon Beacons. In this post I reveal my top 9 Brecon Beacons walks.

Did you know? In Wales we have something called an Eisteddfod, which is basically a festival for all things traditionally Welsh, like poetry and singing. When I was in primary school we were split into 3 teams to compete in things like the Eisteddfod and sports days. The 3 teams were Pen y Fan, Corn Du and Cribyn. I was in Cribyn, so that’s always been my favourite peak in the Central Beacons!

4. The Cwm Llwch Route

Just south of Brecon town there are several Pen y Fan walks that lead to the summit. From the National trust Cwm Llwch car park on Ffwdgrech Road, an obvious path leads directly along the ridge to the top of this famed peak. This out and back trail is the shortest route to Pen y Fan from the north.

This trail can be combined with other paths from the north to make longer loops. For example, to the west there is a path from Nant Cwm Llwch car park which ascends Pen y Fan via a small lake (Llyn Cwm Llwch). Or to the east there is a trail that ascends the ridge to Cribyn before continuing on to Pen y Fan.

Hiking the Pen Y Fan Routes – What do you need?

  • A rain jacket – of course it’s Wales!
  • Water, hat and a warm layer for the top where it’s quite exposed
  • Good hiking shoes/boots – I’ve seen far too many people walking up in flip flops!
  • A map of the Brecon Beacons Explorer 12 and compass (recommended for the horseshoe)
  • Paths are marked on so download the map before you go

Final Thoughts on Hiking Pen y Fan

I can’t remember how many times I’ve hiked up Pen y Fan and I always try to climb it once or twice a year. It’s a great hill.

Remember to check the weather forecast before you go as it can change quickly up there. Try to avoid the crowds on busy bank holiday weekends and most importantly, enjoy the views!

If the weather forecast is looking stormy and wet but you still want to get out, why not do a waterfall walk instead? You can discover the best Brecon Beacons waterfall walks in this post!
