Pen y Gadair Fawr stood at an impressive height of 800 metres, and is an subsidiary summit of the highest peak within the Black Mountains … and that is the summit that is of Waun Fach-(811m). Pen y Gadair Fawr is the second highest peak that’s located in the Black Mountains in south-eastern Wales. Marked by a medium-sized cairn, it is a much more distinguished top than its parent 1.5 km to the northwest. Its 658 metres high top Pen Twyn Mawr is about 2 km to the southeast.

Nice path to summit with some large stepping stones depending on which way you go.

In terms of height, Pen y Gadair Fawr plays second fiddle only to Waun Fach as the Black Mountains' second highest summit. However, where Waun Fach's top is broad and relatively uninspiring, Pen y Gadair Fawr's is a little more like a peak in character. The summit is at a junction of paths: head east for Chwarel y Fan and the Mynydd Du Forest, venture south to Pen Twyn Mawr, or stride northeast to Waun Fach.

Formally known as the Sugar Loaf Mountain and is one of the highest peaks in the heart of the Black Mountains. It stands at 1,955 feet high (596 metres). An iconic peak Its conical shape is reminiscent of a volcano, but the mountain is made of the same old red sandstone as the rest of the Black Mountains.

The roads leading to the Sugar Loaf mountain are all very narrow, 1 car width. You may meet oncoming traffic and need to reverse 100m or more to a passing point. Do not be put off! The car park is small but does have an overflow area 200m before you get to it. The walk leads you naturally into a steep decline into a valley, possibly 130m lower. It doesn’t sound much but the climb from that position is significantly harder. My advice would be to walk around this valley and follow the alternate path. Namely when you walk from the car park do not aim for the top but go further to the left. So much easier to do. The views are stunning and totally worth the effort. Enjoy komooters😀

Pen Y Gadair Fawr has a big cairn on its summit at 800m. It's a subsidiary peak of Waun Fach but probably offers better views standing at the head of the Grwyne Fechan valley. Normally run as part of the excellent Waun Fach horseshoe from either Llanbedr or Crickhowell.

Mynydd Llangorse is a great summit ridge standing between the Waun Fach mountains to the east and the higher Pen y Fan group to the west. It's a nice run from Llangorse Lake or Cwmdu and is also an outlier on the Black Mountain Round. The top is at 1,690 feet (515 m), but the trig point stands at the western end of the ridge at 1,660 feet (506 m).
