About Tarw

The original mountain bike trail at Coedy Brenin (Formerly the Red Bull) and the first dedicated MTB trail built in the UK. This is where it all began, retro, old school, classic, it's all of those things and still stands up well to more modern trails.

 A technically challenging ride with twisting rocky descents and forest road climbs. Tons of single track including the superb 'Pins and Needles' and the unforgettable 'R74'  

How to get there:

Tarw can be started from Coed y Brenin Visitor Centre in Coed y Brenin. Dolgellau, Porthmadog, Bala, Barmouth, Blaenau Ffestiniog, and Machynlleth are the nearest towns or villages.

East off the A470, 8 miles North of Dolgellau just North of Ganllwyd, South of Trawsfynydd. Follow the brown tourist signs.
