The views along the way are generally obstructed by brush and trees for the first half of the climb, but open to rolling hills, grazing sheep, and distant views of farmlands for the second half of the climb.

Herbert’s Quarry is “a large area of abandoned limestone quarries in a stunning location on Black Mountain. The site has panoramic views over the Forest Fawr Geopark and the west part of the Brecon Beacons National Park. The Black Mountain Quarries are a time capsule of a very important aspect of Welsh industrial heritage. There are physical traces of lime exploitation spanning many hundreds of years with quarry workings, lime kilns, and spoil heaps from small scale local exploitation of the 1700s to large industrial use in the 20th century. As you explore the site, you are walking in the footsteps of many thousands of people whose hard work, sweat and drudgery shaped this landscape and left a rich industrial legacy”  (

Black Mountain climb is in the eastern section of Brecon Beacons National Park, Wales, established 1957 and achieving the status of International Dark Sky Reserve in February 2013. While much of the park is bare grassy pastures with Welsh mountain ponies and sheep, it is also known for its many remote reservoirs, waterfalls and caves, such as the 90 foot Henrhyd Waterfall and the Ogof Ffynnon Ddu Cave (Brecon Beacons National Park).
