More Ogwen action, this time at Clogwyn Bwythyn Idwal and from Lewis Perrin. Twr y Tonnau is essentially a direct on Idwal Slab and rates 7A! or perhaps 7A+!?
“You pull on by Idwal Slab but move immediately leftwards into a small, shallow groove. Make a delicate rockover up left, followed by another straight up and you reach better holds. It naturally avoids good holds on either Idwal Slab or the arête to the left. Very nice climbing and quite highball.” explained Lewis.
