The 20.2 km Tarw Du trail (say Taroo Dee) which is Welsh for black bull, was not only the original trail at Coed y Brenin but was widely regarded as the first purpose built mountain bike trail in the UK and probably beyond!
The success of the old revered Red Bull trail is why we have so many great trail centres today. It’s rocky, it’s retro. Now with a brand new section – ‘Y Slab’ featuring several large slabs and some committing features. ‘Look before you Leap’. Have you got the skills to ride the Black bull?
Warning: you will encounter a number of rocky sections including rock steps with a drop of 20cm/8”or more.
The Coed y Brenin mountain bike trails are managed and maintained by Natural Resources Wales. Car parking at Coed y Brenin costs £1 for 1 hour, £3 for 3 hours or £5 for the day – the money collected goes towards maintaining and improving the trails.
