David Howells
April 22, 2026, Torpantau Railway Tunnel

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.
