Coed y Brenin

Cyclists along the Mawddach Trail

Information about cycling around the Mawddach Estuary
Cycle routes: Coed y Brenin

Coed-y-Brenin forest is home to an ever increasing way-marked network of fantastic hand built all weather single-track. There are currently 8 different way-marked routes, but for clarity it should be noted that the different routes share some of their single track sections. For example “The Beast” is essentially made up of the component parts of the “MBR” and “Dragon’s Back” trails. Together, “Tarw” and “The Beast” cover most of the park (excluding the family route). It is worth noting that, to cut down on waste and littering of the forest, the centre no longer provides free trail maps. A map pack can now be purchased at the centre, or alternatively you can download the trail map cards as pdf documents:
