Near its crest, Nebel Horn Ridge rises as a series of stunning buttresses, like colorful sharks fins. Just below the apex, a clean, sharp buttress leans out from the ridge and is characterized by a beautiful green and red south face. Rainbow Bridge follows the arete above and left of the south face, bridging over the colorful face to the blue sky. Work past four bolts on the face via horizontal cracks, pebbles, and edges. It is one of the most picturesque climbs in Boulder.

Belay at a flat rock at the base of a corner below the face. The corner has a tree at the top. Work up the crack on the right for a little challenge (stoppers), or up the easy corner to a broad ledge. The overhang above the ledge to the first bolt is the crux. Pull down on the obvious jug and clip the bolt, pulling past it via powerful moves to more jugs. Good stopper placements in slanting cracks can be found above the first bolt from a good stance, otherwise risk a ledge fall clipping the second bolt. Really fun climbing continues just left of the arete past two more bolts to a two bolt anchor with rap rings. A 60m will reach the flat rock, barely.

It can be VERY windy on this route because it faces southwest and is at the ridge crest. Be very careful not to get blown over the overhanging south face when rappelling.


Stoppers as deemed necessary, 4 QDs and something for the two bolt anchor.
