First time I've ever walked 'below' the imposing cliffs of Garn For, just beyond Trefor village on the Llyn Peninsula. I've climbed the mountains many times, but it's only when you see the other side of these hills that you realise just how steep ly they drop into the Irish Sea.
There doesn't appear to be a path under those cliffs, right around to Nant Gwrtheyrn but I'll do some research!
