Henrhyd Falls and Nant Llech walk


This walk will take you to Henrhyd Falls, the highest waterfall in South Wales, where you can discover wildlife as you walk through the woodland.

Admire the spectacular falls in full flow

After visiting the falls, you will then travel down the Nant Llech valley passing the site of a landslide and also a disused watermill. Henrhyd is best seen after a heavy downpour - the wetter the better! Please take care as paths can get very slippy.

Start your walk from the National Trust car park and pass through two gates, following the footpath down the slope to a track junction at the bottom. Turn left and cross the wooden bridge, walking up the staircase to the footpath at the top. This bridge and staircase was built in 2001 by our staff and volunteers following a landslide. Continue along the footpath to the waterfall. Henrhyd Falls are the highest in South Wales at 90 feet (27m). Take care here as the spray from the falls can make the ground slippery. Once you've taken time to enjoy the spectacular waterfall, retrace your steps back across the bridge to the track junction.

Go straight ahead, following the footpath with the Nant Llech on your left-hand side. The trees that cling to the steep sides of the valley are mainly sessile oak and ash, although you can also find small-leafed lime, alder and wych elm. Keep following the footpath and just after you cross a boardwalk, the smaller waterfall can be seen on your left.

Keep following the footpath until you pass through a gate which marks the end of National Trust land. Then cross a small bridge and continue to follow the path down the valley. After about 15 minutes, you'll reach the site of a large landslide were the path narrows and negotiates its way through the debris.


Continue along this path until you reach the site of the disused watermill - the Melin Llech. (Please do not enter the buildings, they're private property.) From Melin Llech, do not cross the bridge on the left but follow the track uphill for about 25yd (23m). Then join the footpath on your left, continue along the path to a kissing gate and minor road, cross the road and turn right to another kissing gate on your left. Follow the path for another two minutes and the River Tawe will come into view. The River Tawe flows all the way to Swansea and into the Bristol Channel. You have now reached the midway point of the walk.

Return to the minor road by the path you've just followed. Once at the minor road, you can either follow the path that brought you down the Nant Llech, back to the car park, or return along the minor roads via Coelbren.
