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 steep steps to the footpath at the top. The bridge was built in 1985 and the steps were added in 2001 by our staff and volunteers following a landslide that destroyed the original path. Continue along the footpath to the waterfall. Henrhyd Falls is the highest in South Wales at 90 feet (27m). Take care 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 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 (these buildings are private property, please do not enter). From Melin Llech, continue past the bridge on the left and follow the track uphill for about 25yd (23m). Join the footpath on your left and continue along this path to a kissing gate and minor road, cross the road and turn right to another kissing gate on your left.

Follow the path then the River Tawe, which flows all the way to Swansea and into the Bristol Channel, will come into view. You have now reached the midway point of the walk. Return to the minor road by the path you've just followed. Once there, you can either follow the path that brought you down the Nant Llech valley back to the car park or return along the minor roads via Coelbren.
