North Ridge Path to Pen y Fan

Highlight • Viewpoint

A steep but walkable path that leads to the summit of Pen y Fan

Tip by

3.11 km

View of Corn Du and Llyn Cwm Llwch

Highlight • Summit

The views from here are exceptional. To the left you have the beautiful spire of Cribyn, to the right the imposing bulk of Corn Du, and to top it off, in front of you is the last steep, rocky path to the top of Pen y Fan. Simply awesome...!

Cefn Cwm Llwch

Highlight • Trail

This is the ridge route to Pen y Fan from the north. A fine route that steepens sharply near the top.

Pen y Fan

Highlight • Summit

Chief of the Brecon Beacons and the highest summit in south Wales, Pen y Fan is a hugely popular peak with routes to the top to suit everyone from first time day-trippers to potential SAS commandos. Red sandstone creates its unmistakable layered profile and gives hue to the Bronze Age cairn that tops the summit.

Col between Corn Du and Pen y Fan

Highlight (Segment) • Mountain Pass

This easy col between Pen Y Fan and Corn Du is a gorgeous easy hill section no more than a few hundred metres long with minimal height gain and loss. It is very busy for a good reason, as the views north and south are picture postcard. Being a broad col and a bit lower than the nearby summits, it is a popular rest/picnic area. There is also easy access from Pontardaff car park, which is about a 45-minute walk away. This is high mountain country though, so it would be wise to dress appropriately for the weather.

Corn Du

Highlight • Natural Monument

From the 2,864 feet (873 m) summit of Corn Du, you get spectacular views of Llyn Cwm Llwch directly below and over Wales stretching out below. The trail to this peak is great fun, whether ascending or descending. Pen y Fan is very close to Corn Du, so it can get busy here at peak times. Get up early to beat the crowds.

Corn Du summit

Highlight • Summit

Corn Du is rarely climbed alone, but as a peak added to an expedition to Pen y Fan. The climb up is a great one though and the views from the top are absolutely spectacular.

On clear days, you can see all the way to the Severn Bridge and beyond, as well as much of the Brecon Beacons National Park. Be careful in bad weather conditions: visibility can shrink to zero on one of the regular foggy days and strong winds will try and blow your sandwiches away!

Tommy Jones Memorial

Highlight • Monument

The memorial is a 'bit' misleading by way of location, as it was moved by the National Trust some years ago. It used to be a good few hundred metres further over the hill. The erosion to the memorial by visitors was quite extensive, so they moved the plinth next to the path to ease the erosion problem.
