A guide to hiking Pen Y Fan – 3 routes up Southern Britain’s highest peak

Let me start by explaining how to pronounce it! If you’re not from Wales you’d be mistaken into thinking that it is pronounced pennyfan. 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 that’s sorted let’s talk about the hikes. At 886m Pen y Fan literally means the top peak and there are several routes that can take you to the top. It is the highest peak in the Brecon Beacons so whichever way you take there’s definitely a lot of “up”. As such there is no easy route to the top. Some, however, are more straight forward than others. In this post I’ll talk about 3 main hiking routes to the summit of Pen y Fan.


The Motorway Route

  • Distance: 6.4 km round trip
  • Elevation gain: 440m
  • Pros: Easy navigation
  • Cons: Busiest route
  • Map: Brecon Beacons Explorer 12: Landranger 160

This trail is the easiest route 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 the Pont ar Daf car park. 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. To add an extra challenge to your walk you can take the footpath that leads to this peak or if you want to stick with the main objective, take the footpath that leads slightly to the right and takes you around Corn du. Once on this footpath you have one final push and follow it right 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.

Storey Arms 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: Landranger 160

The 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 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!

The Horseshoe 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: Landranger 160
The Horseshoe hike includes all four peaks of Fan y Big, Cribyn, Pen y Fan and Corn Du


This hike is definitely a lot more involved and is a little trickier to get to as it’s not on the main A470 road, but it is a great full day of hiking. The hike starts from the Neuadd Reservoir access road car park. From the car park follow the road north towards the reservoir. The road ends and forks into two paths. 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 onto 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 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 fannybig! After completing the final peak you will see the well made path that takes you back alongside the reservoir to the road that leads back to the car park. Time for a well earned sit down (but sadly no ice cream here)

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!

What will 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 Central Brecon Beacons and compass (recommended for the horseshoe)
  • Paths are marked on maps.me so download the map before you go

I can’t remember how many times I’ve been up Pen y Fan and I always try to climb it once or twice a year. It’s a great hill. Remember, 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 enjoy the views!
