St. Vrain Canyons Rock Climbing
Patty Johnson bouldering at Buttonrock Reservoir.
This is a set of 3 canyons that are the drainages of the South, Middle, and North forks of the St. Vrain River. The greatest bulk of the climbing to date is in the South Fork. The rock is granitic and at times on the coarser side. There are a variety of routes here, some traditional, some sport, even some ice/mixed
. Most of the routes are shorter here, maybe up to 5 pitches in length. There is still a decent amount of rock to explore here. While there is some friable rock in places, the bulk is good quality. Poison ivy does tend to flourish in spots here, so the sensitive should be aware.
Most will drive up US 36 or CO 66 west to Lyons. From there, the forks diverge. The South and Middle Forks are accessed off of CO 7. The North Fork is accessed off of US 36.

The Temptation Arete is an amazing line with a bit of agonizing history. It has been called, "perhaps the best line in the South Saint Vrain Canyon". The climbing moves were originally freed by rope solo (RW) on jugs and the bolts placed accordingly. My own first lead was very scary. Subsequent attempts by Greg Purnell, Alan Nelson, and Mark Rolofson (all very strong climbers and much better climbers than myself) led to the consensus demand for re-bolting, with new placements described in detail...[more] Browse More Classics in CO
