Description Suggest change

Also located west of Lyons, this area is cousin to the South Saint Vrain (SSV). Like the SSV there are both trad and sport routes on a variety of features. Rock quality varies from superb to choss. One of Buttonrock's centerpieces is the classic River Wall. This steep wall has steep cracks alongside of both technical and pumpy sport routes. Well-known climbers from Boulder and around the Front Range developed this area in the last three decades. The best climbing season is whenever it isn't precipitating, possibly year-round as the aspect of the formations is diverse. River Wall in particular has midday sun, but is often chilly due to breeze off the river. The Falcon guide to Lyons area covers both Buttonrock and the SSV.

Getting There Suggest change

Drive to Lyons on CO 66, this can be reached via US 36 from Boulder. Continue past the junction in Lyons of US 36 and CO Hwy 7 (CO Hwy 7 takes one to the SSV) for about 3.7 miles. Look carefully on the left for a sign for Shelly's Cottages. Turn left here on County Road 80. One half-mile on the left are Entryway Slabs, another tenth of a mile are Buick Rocks and Hitler's Sex Life. About 2.3 miles further one reaches a steel gate and parking. One can hike along the road to reach River Wall, Old Yellar, and other formations.

Dogs not allowed as of 5/15/23
