St. Vrain Canyons Rock Climbing
Working the easy part of the route.
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.

Excellent route with 3 cruxes and two rests and some variability in opinion as to the relative difficulty at the cruxes. It may depend somewhat on the fact that for the 2nd two cruxes, there is different beta potential. I personally find the 1st crux to be the hardest once you know the route, but probably easier to onsight than the 3rd crux. Anyway, this is an excellent route. A little runout with clean falls in 2 or 3 places, but well-thought out bolt placements. Use of a long runner on bolt @P...[more] Browse More Classics in CO
