Mynydd Du Forest
This large area of woodland in the Black Mountains has miles of forest tracks suitable for walking and mountain biking. The waters of the Grwyne Fawr run through the woods so there is the option of a waterside walk to the nearby Grwyne Fawr Reservoir along the river. You can start your exercise from the Mynydd Du car park at the northern end of the woods, a few miles west of Llanthony. It's situated in a nice spot at the end of a country lane just next to the river. From here you can pick up the forest trails through the western side of the woods before crossing the river at Pont Cadgwan and returning on the eastern side of the river. There's lots of attractive trees and plants and some steep climbs with great views of the surrounding hills. The riverside sections are lovely too with lots of pretty waterfalls to enjoy.
If you would like to continue your walking in the area then you could climb the nearby Waun Fach. It is the highest mountain in the Black Mountains and located just a few miles north west of the forest. From here you can pick up the Dragons Back circular walk which provides magnificent views over the area.
Just to the north of the car park is the lovely Grwyne Fawr Reservoir. You can follow a riverside path right to the water from the same start point as this walk.
