Rainy Day Rock is not much more than an overgrown boulder. The crag is quite overhung so most routes carry a good pump factor. The rock is solid and has a variety of climbing from edges, to jam cracks, and mantles. Eight or so bolted lines exist, and one trad route. Numbering begins from the right side with Your Brain on Rain.
Getting There
Three miles up Clear Creek Canyon is a large parking area just before you get to the first bridge. This generous space provides parking for the ice routes, the Pile Driver formation, The Red Slab, The Little Eiger, and Rainy Day Rock. From the West side of the bridge, take a sharp turn, pick up the trail, and it will take you right there.
This little crag packs some punch, although as noted these routes are more or less glorified boulder problems, with bad downhill landings. The 3 routes through the middle 13/12/11c are worth the go if you are at Little Eiger and want something to finsih off the day with a kick.
