This untroddon route rises from Gwastadnant in the Llanberis Pass up to Llechog, a minor top below Crib y Ddysgl.

If the hard start and all difficulties are avoided it can be scrambled at grade 1

There is some vegetation which gives problems in the wet, but it can be escaped from easily at many points. Cross the bridge over the river at Gwastadnant and walk past houses to gain the open hill. A rocky rib is met; either scramble over it or avoid it until the fearsome Llechog Buttress towers above.

Here move right to the base of the gentler looking ridge, which has a steep tower at its base. The tower is climbed on its left side. The first break is a crack filled with chockstones; ignore this. Further left is a slot/recess. Start on its left side and traverse a few metres across right to a shallow chimney, which is then climbed to the top. Here follow a rib over the tower to a small saddle.

This start isn't massively difficult but is exposed so if you'd rather avoid it walk up below the tower to reach the saddle. From the saddle walk round the steep slab with the fence up it to reach a wall. Climb a rib to its left to reach a steep little face.

A quartz break can be climbed here, but this is tricky. If in doubt move left to find an easier way. Above, the angle eases and any line can be taken with a choice of grade. The most entertaining obstacle is a 10m crack ascending a slab. It's harder than it looks though (with high potential for getting a boot stuck) so it is worth roping this pitch.

Higher up where the ridge narrows the rock becomes more brittle and steepens a little, before you emerge at the top. Here you have several choices. The summit of Llechog is a short walk to the left, and beyond this is Crib y Ddysgl and Snowdon. If you'd rather avoid the crowds though, the best bet is to walk down the ridge to the right to Llanberis.
