With the new slate guide getting its final fiddle, here's a little known wall..
This is the South wall of Twll Mawr; the one you throw stones down while toddling along the tourist path. The two routes in the bottom are 7c ish sport routes not in the current guide, and the two at the top are Wolfhound and Birdman, both in the existing guide.
The rest is unclimbed and mainly unexplored. the two down arrows mark bolted abb stations and the up arrow...
Well that's the gift, an awesome groove tucked out of the yob's stone fire, that may even go bolt free.
Tad shady tho'
