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.

Royal Arch (Post work hikes)

Chautauqua Trailhead

Let's stretch our legs after work, and go for late hike. Royal Arch is one of my favorite hikes in Chautauqua Park, beautiful challenging short hike (3.75 miles out and back, with 1380 feet of elevation). https://www.alltrails.com/trail/us/colorado/royal-arch-trail Bring water and your MASK. Bad weather postpone.

Front Range 13ers: Pettingell Peak (13,553') via Herman Lake *DAY HIKE*

THIS IS A STRENUOUS HIKE!! Join us for a hike of Pettingell Peak, a 13er near I-70 before the Tunnel. Pettingell is notable only for being the highest point in Clear Creek County. On our way up, we'll pass by Herman Lake, a pretty lake. It's a class 2 to get to the summit with no exposure. The total distance is roughly 8.5 miles RT and about 3200' of gain. Meet at the Eldo Park n Ride and carpool to trailhead. Trailhead is off of Exit 218 on I-70 at Herman Gulch Trailhead. You can meet us there around 7am or so. Bring microspikes, snowshoes, gaiters!

(International) Bolivia Mountaineering Expedition 2017
Needs a date and time

Needs a location

Located near the city of La Paz, the Cordillera Real offers some of the best mountaineering in South America. Easy access, stable weather, excellent climbing conditions, interesting culture and relatively easy to moderate routes makes this a good place to start climbing peaks over 14,000'. We would go down for aprox two weeks (with prior acclimatization here in CO) somewhere between June and August. Prices would range somewhere between $1500- 2500 pp, not including airfare, but I'm still working on logistics. Looking for 2-3 climbers to form a rope team. Prior experience with; snow/ glacier travel, crevasse rescue and Avy level 1, 2 or both. Wilderness First aid, WFR or other medical training is a bonus. Spanish would be incredibly helpful. Possible objectives; Pequeno Alpamayo (17,618), Huayna Potosi (19,974) and Illimani Pico Sur (21,125). These are not technically hard and are fairly strait forward peaks. However they are challenging due to the high altitude and glacier travel.
