Fforest Fawr Circular Walk

The rugged terrain and faint paths along the Fforest Fawr Circular Walk can make it a difficult trail to navigate, especially for beginner walkers. If you are planning to set out on this adventure, be sure to bring a GPS, good trail map, and a compass in order to avoid getting lost in Brecon Beacons National Park. Additionally, you will want to wear proper walking boots to better traverse the steep slopes and often boggy landscape along this route.

Even though it may be tricky to navigate at times, the Fforest Fawr Circular Walk is an exceptional route that will allow you to disconnect from the outside world and enjoy some quality time in the wilds of Wales. Stunning views from atop Fan Llia and Fan Fawr await on this rugged adventure through Brecon Beacons National Park.

Setting out from the car park, you will make your way to the southwest and begin climbing gradually up the hillside across the barren landscape. After heading right at the fork in the trail, you will continue on and keep to the right for the next 2.2mi, traversing the edge of the steep hillside and crossing over a number of small streams before arriving at a junction in the trail on the edge of the Craig Cerrig Gleisiad a Fan Frynych National Nature Reserve.

Take the path on the left and continue on towards the southwest, traversing the undulating landscape over the next 2.8mi and taking in the beautiful views of the surrounding mountains as you make your way to the summit of Fan Llia. Here, you will enjoy a commanding sightline across the rugged landscape of Brecon Beacons National Park, including the next stop along the walk, the Ystradfellte Reservoir in the valley below.

Continuing on to the southwest, you will keep left along the footpath to begin the steep descent of the mountainside towards the reservoir. This is the point of the walk where navigation will become a bit tricky, as the path becomes quite faint leading up to and after the reservoir. Make sure to utilize your GPS or a good trail map with a compass to ensure that you do not lose your way.

After arriving at the edge of the Ystradfellte Reservoir, you can pause for some lunch and to take in the beautiful views across the surface of the water, before making your way across the dam wall to continue your adventure. Once you have reached the opposite side, you will climb uphill along the faint trail to the northeast, using the trickling waters of Nant Cwm-Porth as your guide.

After climbing uphill to the northeast for 2.0mi from the reservoir, you will arrive at the summit of Fan Fawr, where you will enjoy spectacular views of the surrounding area, including Pen-y-Fan to the northeast. Once you have taken in the views, follow the trail asd it leads downhill to the northeast, continuing on for another 1.0mi in order to arrive back at the car park where you began the Fforest Fawr Circular Walk.
