Great mountain road, rideable on a gravel, comfortable on an MTB

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'.

Lovely quite road with some good hills, but it's worth it for the views.

It's a long slog of a climb from the south - but don't despair the scenery is amazing, and well worthy of every pedal stroke.
