What we're about

CHAOS is an informal, Boulder-based group of energetic, fun, non-competitive, backcountry enthusiasts who are in their 20s, 30s, or 40s who enjoy self-powered and self-organized activities including hiking, backpacking, biking, snow shoeing, skiing, mountaineering, and river sports.

CHAOS' main Goal is to be a community through which one can make life-long friendships, share backcountry trips, expand outdoor and leadership skills, appreciate nature and enjoy the sense of community, teamwork, and challenge that prospers in backcountry situations.

As a member you will be able to check activities on this website, and post your own trips/events. Note that all trips should be for CHAOS by CHAOS, outdoors, and self powered.

CHAOS actively encourages its members to organize trips but does not supervise the activities. CHAOS is not a guide service and a person should only go on trips they feel are appropriate for their ability and experience level.

If you have questions, ask the trip organizer! Many trip organizers love to help out new members and will gladly answer any questions you have about the trip, what equipment to bring, etc. Above all else, have fun and be safe!

Here is a Welcome To Chaos document with more information: https://docs.google.com/document/d/1aLFTysl452wTZcaSYt3KP4brsqsqL867Cos1xZ2gavg/edit?hl=en_US

Many past and present members believe that CHAOS enormously improved their "young adulthood and pre-family" phase of life. To ensure that this wonderful opportunity remains for future members, they should be in their 20's, 30's or 40's when they join CHAOS.

If the members’ ages or the group’s style don’t feel like a good fit for you, we suggest you check out one of the other great clubs in Boulder like the Flatirons Ski Club, the Boulder Outdoor Group, the Colorado Mountain Club, the Boulder Nordic Ski Club, the Sierra Club, or the C.U. Hiking Club (office in UMC).

Please be respectful when you RSVP to events, and only RSVP if you know you will make the event; especially if there is a limited number of spots available. If you end up with three no-shows; whether it's a no call/no show, or a cancel at the last minute; you will be removed from the group.

Vegan CHAOS Potluck ~ Share your Outdoor Tales over a cozy dinner!

A CHAOS tradition has been to have a monthly potluck. It is a great opportunity to meet new friends, hear about upcoming trips and plan new ones. ~ Please BYO plate, cup and fork to be good to the environment. ~ Consider coming by bike or bus. The Skip and 204 stop 1 min walk away! ~ Bring a main course, desert, or drink to share with 4-8 people. (Reminder that vegan means 'no animal products,' so no meat, milk, fish, eggs, honey, or other pesky ingredients, like 'whey.') - BONUS: Bring a map to share a trip you really enjoyed or one you would like to do soon! I'm looking forward to connecting over dinner and planning more outings soon! Looking forward to seeing you!
