These routes are waymarked routes but should be used in conjunction with an OS map or GPS device. Please be aware - you will be in some remote and at times, inhospitable areas of the countryside.

Cli-Machx Click Here for Cli-MACHX

The cli-machx was built in 2005 and is sited in the Dyfi forest.

It's a 15km round trip, with 9km of built single track with compressions and whoops, rock slab drop-offs and some beautiful flowing turns.

The last descent is the longest in Wales and features rocky jumps; watch out for the 'eye of the needle'; a huge jump with a narrow landing between two trees on the other side.
The finale is a sequence of eight huge berms following quickly after each other. Hit them high enough and fast enough and they ride really well, but don't look down!

There's also plenty of informal free-riding in the forest, but it isn't waymarked, so take a map or get a local guide. 

This trail is graded as red, although the second half of the last section (Tony the Tiger) is graded as black.

Please note, this is a forest that is used for motorsports about 5 weekends a year. No mountain biking on these days, we don't want anyone getting squished. Please see home page for closure dates.

MACH 1     Click Here to see the Route
This route takes you South West out of Machynlleth to the neighbouring village of Derwenlas and along the picturesque Llyfnant Valley. The route returns via the highest point of Bryn Coch Bach, the point where Mach 1, 2 and 3 meet, with a screaming descent back down to Machynlleth. A fast rather than technical 16km, although considerably more tricky in the wet. Covered by Outdoor Leisure 23.

MACH 2    Click Here to See Route
This route takes you South East out of the town along the river Dulas and across open farmland where you ride along Glyndwr's Way, made famous by the first Prince of Wales, before dropping down to Talbontdrain. A steep climb up to the forest is followed by a long flowing descent to Bryn Coch Bach, and then the final descent of Mach 1.Covered by Explorer 215.

MACH 3    Click Here to See Route
This route shares some trail with Mach 2, before heading off south through the forest and onto the moors before returning along some sweet track and grass descents. From the furthest point, the adventurous can take a spectacular cross country ride all the way to Nant yr Arian. The highlight of the return leg is 'the Chute', very steep and very rocky, and then to top it off it gets very dark. Covered by Explorer 215.
