St. Vrain Canyons Rock Climbing

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.

Per Athena G: consider covering your skin with protective clothing. Biting flies are invasive here and will bite you often. Do not use weak insect repellent. Wear protective long sleeves and pants. Limit exposed skin. Treat clothing with DEET, and use strong DEET as needed on other areas to prevent bites. Flies may still bother you. Proper use of strong insect repellent is essential to enjoy your time here.
