Cambrian Way: Cwm Bychan to Maentwrog

We'll meet in Maentwrog, drive everyone to Cwm Bychan and walk back.
It's not the longest at 10 miles with 2,700 feet of ascent, but it looks like there's some pretty tricky terrain.
We start with a tough climb and ridge walk along Craig Ddrwg, with a few gentler ups and downs but on tricky terrain. After that it should get a bit easier as we descend to Llyn Trawsfynydd and on to Maentwrog.
