Gwaun Hepste, near Merthyr Tydfil

What's here


Gwaun Hepste is set within Waterfall Country in the Bannau Brycheiniog (Brecon Beacons) National Park.

This popular car park is the starting point for the Four Falls Trail, the legendary circular trail to the woodland gorges where four of the area’s most spectacular waterfalls are found.

The main paths on the Four Falls Trail are wide and easy to follow but the optional signposted sections to the best views of each waterfall follow narrow, steep paths which are rocky and can be slippery.

Keep safe in Waterfall Country 

Waterfall Country is a spectacular landscape but serious accidents do happen to visitors here and there have been five fatalities in just two years.

You are at risk of life-changing injuries or death if you decide to enter the water.

Don’t be tempted to jump into a pool or wade into a river for a swim as the water is cold, deep and fast flowing with slippery rocks, strong currents and hidden hazards.

Never take part in activities like gorge walking, canyoning or scrambling unless you are trained to do so or are under the supervision of a registered and licensed operator.

Wear walking boots, use extreme caution around water and keep on the waymarked paths as they offer you the safest route - going beyond the waymarked trails is highly hazardous.

Walking trail

The walking trail is waymarked from start to finish.

Look out for the information panel at the start of the trail.

Four Falls Trail

  • Grade: Strenuous
  • Distance: 5¼ miles/8.4 kilometres
  • Time: 3-4 hours
  • Trail information: The main circular trail is waymarked with red arrows and follows paths that are generally wide, and in most places have a stone surface. The gradients are gentle and there are very few steps. It takes about 40 minutes to reach the first waterfall. The waterfall link paths are waymarked with green arrows. These are optional there-and-back routes to views of the waterfalls which follow paths that are narrow, unsurfaced and slippery in places, with many steps. They are particularly rough and rocky next to the waterfalls. Wear sturdy footwear and be aware of unguarded steep drops, especially when taking photos. Don’t be tempted to swim in the water – it can be cold and fast flowing.

Waterfall Country

Gwaun Hepste is in a popular part of the Bannau Brycheiniog National Park known as Waterfall Country.

Nowhere else in Wales is there such a richness and diversity of waterfalls within such a small area as Waterfall Country. Here the rivers Mellte, Hepste, Pyrddin, Nedd Fechan and Sychryd wind their way down deep, tree-lined gorges, over a series of dramatic waterfalls, before joining to form the River Neath.

Whether you are looking for a whole day adventure or an hour’s stroll you should be able to find a route suitable for you.

Waterfall Country lies largely within woodland jointly managed by Natural Resources Wales and the National Park Authority. Together we manage the paths and help you explore and enjoy this unique area.

Go to the National Park's website for more places to visit in Waterfall Country.
