Embark on the Ystradfellte Waterfall loop, also known as the Four Waterfalls Walk, starting from Pontneddfechan in Bannau Brycheiniog (Brecon Beacons) National Park. This difficult jogging route covers 10.7 miles (17.2 km) with a significant elevation gain of 1228 feet (374 metres), typically taking around 1 hour and 56 minutes to complete. You will navigate varied terrain, including natural, unpaved, and gravel surfaces, winding along riverbanks and through lush, forested valleys.
Be prepared for rocky and often muddy conditions, especially after rain, so good footwear is essential for sure-footedness. The route features numerous steep ascents and descents, with some sections incorporating boardwalks and steps. Certain areas, particularly around the waterfalls, can be very slippery and require caution. This trail is unsuitable for beginner runners or those not accustomed to challenging off-road conditions.
The Ystradfellte loop is renowned for its close-up encounters with four distinct waterfalls, set within the dramatic limestone gorges of "Waterfall Country." The most iconic feature is Sgwd yr Eira, meaning 'Fall of Snow,' where you can famously walk behind the curtain of water. The trail's location within the Fforest Fawr Geopark highlights dramatic geological formations alongside the natural beauty of the cascading waters and ancient woodlands.

The Fan Gyhirych & Fan Nedd loop from Afon Lila offers a challenging jogging experience through the Bannau Brycheiniog (Brecon Beacons) National Park. This difficult 12.8-mile (20.5 km) route features 2381 feet (726 metres) of elevation gain and typically takes around 2 hours and 42 minutes to complete. You will encounter varied terrain, from gravel tracks and grassy paths to rough moorland and potentially boggy ground, especially on the less-used sections leading up Fan Nedd. From the summits of Fan Gyhirych and Fan Nedd, you can enjoy expansive panoramic views of the Carmarthen Fan, Pen y Fan, and the Cray reservoir, offering a true sense of wilderness. The final push to Fan Nedd's summit includes brutally steep climbs, demanding good fitness and sure-footedness. This trail is ideal if you are looking for solitude away from more crowded paths.
Planning your visit requires you to be prepared for diverse conditions, as some sections can be steep and eroded. Sturdy shoes are recommended, especially if you are not used to alpine conditions. The route is generally considered a hard run, so ensure you have very good fitness before attempting it. While the research does not specify trailhead access, parking, or public transport details, it's wise to check local information for Afon Llia before you go. Always carry enough water and supplies, as the area is remote and services are limited.
This loop is rich in history and natural interest, incorporating parts of the ancient Sarn Helen Roman Road and passing by Maen Madoc, a Bronze Age monolith. You will also follow sections of the Beacons Way and the Cambrian Way long-distance trails. Reaching the trig points on Fan Gyhirych (725 metres / 2,379 feet) and Fan Nedd (663 metres / 2,175 feet) provides rewarding views across the Brecon Beacons. A significant portion of your return leg crosses the Ogof-Fynnon-Ddu Pant Mawr National Nature Reserve, adding ecological value to your run. The landscape also reveals historical remnants like shake holes, disused quarries, and mine shafts, reflecting the region's industrial past.

Maen Madog also called Maen Madoc is a standing stone in the heart of the Brecon Beacons National Park, about one mile north of Ystradfellte. It stands immediately beside the old Roman road known as Sarn Helen, just outside the Blaen Llia forestry plantation. A mile to the north is Maen Llia, a Bronze Age standing stone. The stone is not in its original location, and no grave has been found. Historians theorise that the burial remains were destroyed by the extremely acid soil. When Maen Madoc was recorded in 1805 it was recumbent. It was re-erected at some point in the 19th century and again in 1940. It is believed to have been erected in the late Roman period, possibly to mark the site of an early Christian burial. The southwest edge of the stone is inscribed with very worn Latin text reading 'DERVAC(IVS) FILIVS IVSTI (H)IC IACIT'. This translates loosely as 'Dervacus, Son of Justus lies here'. One theory says that Maen Madoc was a pre-existing Bronze Age standing stone that was simply re-used to mark a late-Roman burial site.

Sgwd yr Eira is the most impressive waterfall in the Pontneddfechan area. It is a high, broad, and powerful waterfall that resembles a curtain of water when it is in full flow. The fact that you can walk behind it just adds to the beauty of this amphitheatre you find yourself in. To get there, however, you have to take around 170 steps that go down the steep side of the valley to the river bed. If this worries you somewhat, just take your time when you go down and when you come back up. In addition, at the bottom, the path that goes to the waterfall is rocky and slippery, and if you walk behind the waterfall, it will be a bit wet, so a waterproof might be necessary.

As well as the caves, here you have Porth yr Ogof car park, or Cwm Porth car park, to give it its proper name. It's one of the better car parks, with toilets and a small shop. On most days there is also hot food and drinks available. The famous Four Waterfalls walk also starts from here. This is a spectacular walk, and each waterfall is great in its own way. They are Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira.

The Four Waterfalls Walk is my idea of heaven. Hidden away in a quiet corner of the Brecon Beacons, there is a famous waterfall trail that takes in four great waterfalls, it is located near the quaint village of Ystradfellte. The trail has stunning scenery, and the main access to it is from the car park at Porth yr Ogof, or the Cwm Porth car park, to give it its proper name. The Four Waterfalls are all spectacular in their own different ways, and they are Sgwd Clun-Gwyn, Sgwd Isaf Clun-Gwyn, Sgwd y Pannwr, and Sgwd yr Eira.

Sgwd Isaf Clun-Gwyn is one of the most photographed falls on the four waterfalls walk. Thus, it is known as the “Lower” Fall of the White Meadow in English because it is on the same river and you have to head downhill to get to it. It is a great place for gorge walking, and I have had a lot of fun here over the years. It's a gorgeous place to come and visit in waterfall country.
