This is the first proper off-road section on Traws Eryri heading north. If you're riding an MTB with nice big tyres it's a blast, but if you're on a gravel bike, it's a long, picky descent.

Heading south, this is a great, usually traffic-free descent. Heading north it's a hard climb with some 15%+ ramps especially towards the top.

Heading south, once you're away from the main road this is a lovely steady climb with a few steep ramps. Look out for plane-spotters who hang-out at the top waiting for military aircraft doing the low-flying 'Mach Loop'.

The pass between the breathlessly rugged Rhinogs Fach and Fawr is notorious. Many who have explored this way have been taken aback by a rough hewn landscape of concealed boulders and heather that doesn't give up its secrets lightly. From the bwlch are superb views across to Lake Trawsfynydd and the Arenigs. Both Rhinog Fach and Rhinog Fawr can be ascended from here.
