At the Colorado Mountain School, we are the descendants of a guiding tradition that began in 1879, when the first local guides began leading climbers to the summit of Longs Peak. Today, we are Rocky Mountain National Park's exclusive climbing concessionaire and the largest climbing guide service in Colorado. We are American Mountain Guide Association (AMGA) accredited and many of our guides are AMGA certified. No U.S. guide service has made a greater commitment to professional training at international standards. But in addition to technical ability, Colorado Mountain School guides are chosen equally for their love of teaching and for their considerable inter-personal skills.

We teach climbing and offer a comprehensive climbing program. Our home, in Estes Park and Boulder, is a climber's paradise of rock walls and alpine spires and includes some of the most famous routes and peaks in North America. We teach courses and guide climbs on rock, snow, and ice, including avalanche instruction and ski mountaineering. We can guide you on a route you've dreamed of or teach you the skills to climb it on your own. Whether you're just learning to tie a Figure-Eight knot or seek to test your limits on the East Face of Longs (The Diamond), I invite you to join us. Colorado Mountain School guides are eager to share their knowledge and love of climbing and the mountains with you.
