The mountains have a profound ability to make us feel alive. Colorado Mountain School exists to share the power of the mountains with those who seek knowledge and adventure. They are a community of top-notch climbing and skiing professionals dedicated to mountain experiences that are educational, fun, challenging, and life-changing.

Colorado Mountain School is a professional climbing guide service with a long and rich history in Colorado and in the surrounding areas. CMS, under various names, has been guiding continuously in Colorado since 1877. Mike Donahue purchased the company in 1981 and gave it its present name. John Bicknell bought the company in 1999 and eventually sold it to the previous owner Russell Hunter in 2016.

Today, CMS is the largest guide service in Colorado and has more AMGA certified guides than any other guide service in the state. They have developed the most complete outdoor climbing curriculum in the United States. Their offerings range from one-day courses such as Intro Rock Climbing and Big Wall Clinic, to multi-day courses such as our three day AIARE Level 1 course and our five day Rock Climbing Development Series. In addition to the myriad courses, they guide rock, ice and mountaineering throughout the Colorado Front Range and internationally. Their mission is to provide unparalleled customer service and world class climbing and skiing instruction, while setting the standard in professional guiding.
