Our mission is to promote long-term investment in the Dyfi Forest to develop a network of the best mountain bike and off-road cycling trails in the UK while maintaining the feeling that Dyfi Forest is the gateway to the wilderness.

On the last weekend in July we welcome Grinduro Wales to the Dyfi Forest an event that combines the best elements of a mountain bike enduro with a gravel grinder-style road race.

Just announced for June 2022 is the Cymru MTB Classic, part of the legendary Epic series of races and which will also use some of the trails in the Dyfi Forest


As Wales comes out of lockdown and we are able to welcome visitors to the Dyfi again, we have finished installing the new signposts of the Mach trails and are working to ensure that all the trails are riding well. 

Additionally we are working on updating the website to provide you with the best information possible to ensure that you can make the most of your time in the Dyfi.
