The Rock Bottom Line*** 7b+
135m, 5 pitches. Once the longest fully bolted sport route in the UK now the 4th longest to 'Tan y Ddraig' still a great adventure from the very bottom of Twll Mawr to the Top of the Quarryman wall.

Pitch 1 (30m)F6b Climbs the Slab in the corner with some bridging. Clip the high 9th bolt and carefully traverse right avoiding the scree ledge to a double bolt belay.
Pitch 2 (30m)F7a Takes the obvious crack and flake line, easy to start, with a hard move over a bulge near the top to a ledge and double bolt belay where Opening Gambit used to cross.
Pitch 3 (30m)F6b The slab / wall to a ledge at the foot of a short groove and possible belay ledge (2 bolts) continue up the arete past 3 bolts taking you to the 'Matilda Ledge' double bolt belay.
Pitch 4 (25m)F7b+ The immaculate green groove above beckons. A beginners Quarryman groove. 2 bolt belay below Wonderful World of Walt Disney.
Pitch 5 (20m)F7b Belay a few feet further right. Take the flake / crack system up the attractive bulging slab / wall. The thin crack doesn't take fingers very well. Crux is either a high step up right or left take your pick.
