Torpantau Tunnel is a closed-down, 666-yard-long abandoned masonry railway tunnel in Wales that was opened in 1863 and closed down in 1963. It was part of the Brecon and Merthyr Railway line and, at 1,313 feet above sea level, was the highest tunnel on the UK railway network. Now it is disused but is often used as part of team building and adventure walks by local activity providers. If you are thinking of using it, you will need wellingtons (which will just about keep you dry) and a head torch. It is a brilliant place to lead a group of kids through and jump out to scare them half to death.

Nice little rock that sits out beyond the edge that can create a nice photo effect

Cribyn is the smallest of the Brecon's 'big Three, but it is a shapely top and should be included in any climb up here.

When coming off the mountain to go down towards the car park it’s quite a steep scramble and can be slippery

Fantastic views from the top. Just take your time and don’t burn those legs out too soon.

Completed on a cold, icy morning. Even though sun was on this section - there were some very slippy areas, so proceed with caution. Otherwise generally good climb

The Stunning Blaen-y-Glyn Uchaf- located in Talybont has many different routes, with plenty to discover views are breathtaking. Another beaut and tip to visit is.. The Blaen-y-Glyn Uchaf waterfall circular and the Wellington Bomber Memorial Trail is fantastic walking route in Wales that will take you through the mountainous terrain of Brecon Beacons National Park to visit the crash site of a World War II Canadian bomber plane. While out walking you discover paths looping around Bwlch y Ddwyallt and Waun-Rydd to arrive at bomber site.
