Marin (red difficult grade) Trail (15.5 miles, 25 kilometres)
The Marin Trail is a proper mountain bike trail in every sense of the term. Big climbs, big descents, brilliant singletrack and truly awesome scenery make this a trail to remember. Most, but not all, of the climbs are on forest roads and tracks giving you time to take in the views of the mountains of Snowdonia, and all of the descents are on singletrack. The singletrack varies from very tight, technical and rocky to wonderfully open and flowing, from dark forest to exposed ridgelines.
More information in relation to whether or not this is suitable for you and where you can get training can be found on the Natural Resources Wales website.
Car parking is free of charge.
Turn west off the B5106 near Gwydir Castle, Llanrwst, onto a minor road into the forest. Then take the first forest road on the left signposted Sawbench/Mainc Llifio.
The nearest station is Llanrwst.
The OS grid reference is SH 790 609.
