Colorado Mountain Club - Boulder Group

Our members benefit from close proximity to the Flatirons, Boulder Open Space & Mountain Parks, Brainard Lake Recreation Area and many amenities unique to Boulder, to enjoy a huge variety of hiking, backpacking, climbing and skiing activities throughout the entire year in addition to local social outings.  Boulder outings run the gamut from leisurely slow-paced flower photography hikes and conservation projects to challenging high mountain summit climbs.  We are friendly and we like to have fun!

For all level mountaineers, Boulder provides frequent local hiking series such as Rise & Grind (an early morning hike & coffee club), High Peaks Hooky (weekday hikes to local peaks), Hiker's Happy Hour, Scrambling, Backpacking, and other outings. 

We also offer courses in Scrambling, Trad Climbing, etc. and are increasing our collaboration with Denver's schools. Please let us know if you are interested in taking or helping revive the below:

• Boulder Hiking School for people new to the Colorado mountains
• Boulder Mountaineering School (established in 1947) for members interested developing more technical mountaineering skills
• Advanced Mountaineering School for those who think they might like to tackle full-scale mountaineering expeditions
