10b or Not 10b

From the anchors of Castles Made of Sand, move right and follow the bolt line straight up the long slab to a final headwall with a stout move. An excellent link up is to climb Crimson Arete (5.10a) and pull over the lip to the stance above the anchors then continue up to Castles Made of Sand anchors clipping a bolt along the way. It's possible to link Crimson Arete and 10b or Not 10b into a single long pitch.

Route starts at the anchors of Castles Made of Sand. Two single rope rappels gets you back to the ground.
