The Colorado Mountain Club is the premier hiking club of the Rocky Mountain Region.

We are organized: "To unite the energy, interest and knowledge of the students, explorers and lovers of the mountains of Colorado; to collect and disseminate information regarding the Rocky Mountains in behalf of science, literature, art and recreation; to stimulate public interest in our mountain area; to encourage the preservation of forests, flowers, fauna and natural scenery; and to render accessible alpine attraction of the region."

To find out more about the CMC Boulder Group, we suggest you view the information under the 'Group' and 'Publications' menu items.

There are no strangers in the mountains, only friends you haven't met.
