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.

This is great fun, I've done both descents now, both north and south but neither climb, and I'm very happy about that. Would want an unloaded bike to clean the whole trail.

Steady climb with lovely views of the valley. Bothy is usually busy over weekends so if you're keen to stay there without company, head up midweek outside peak season. Otherwise, embrace the spirit of what you set out to do and share an evening with a fellow bothy fan!

Can be very boggy out of the summer months, lovely gentle climb, technical in parts but the views make up for it. Ride the full distance and you literally see the BB National park drop away into the plain below.
