You'll find this enjoyable and airy face climb on the extreme left side of The Sentinel's west face, although the climb actually faces north towards the Thin Wall.
Scramble up blocks and ledges to reach the base of the actual climbing up a smooth expanse of rock that sweeps gently upwards. Easy climbing to begin, that slowly increases in difficulty as the angle steepens near the top and you become aware of the exposure afforded by it's position. Rap off from anchors at the top of the route. Two stars out of five.
