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.

Upcoming events (4+)

After-Work Paddleboard/SUP > Union Reservoir in Longmont

Needs a location

We will meet at 6 PM at the boat ramp at Union Reservoir (which is near the entrance gate) for introductions. And then we will launch from the boat ramp after introductions for an enjoyable after-work paddle session.

Bring dinner or snacks in a dry bag, and perhaps a headlamp, depending on how long we want to be out there. And be sure to bring a PDF (per reservoir regulations).

Sunset is at 8:34 pm on Monday, June 27. And the high in Longmont is 85 degrees that day.

There is a fee for your car to enter ($10/weekdays) and there is a fee per paddleboard.

- Rocky Mountain Paddleboards, which is located near the entrance gate, are unfortunately open from only 9 am to 6 pm so that is not an option.
- You can rent a paddleboard from Crystals in Boulder, CO.

- We will check the weather on Monday afternoon, and if the winds are high or are forecasted to be high that evening, then I will cancel this event.

And this is what to expect for wind, wave and weather for Longmont (Union Reservoir), for a local forecast:

I hope that you join us!

Lower and Upper Crater Lakes (JPW) SUNSET HIKE

Needs a location

The Crater Lakes consist of three lakes in the James Peak Wilderness area. This hike will take us up to the Upper Lake, which sits in a gorgeous basin just below the rugged cliffs of the Continental Divide.

The total length is roughly 7 miles with about 2000' of gain.

The portion up to the Lower lakes is a nicely maintained trail. The portion to the Upper lake is a rougher, steep trail.


Meet at the Nederland Park n Ride at 4pm to coordinate carpool

Bring the usual hiking kit and a headlamp!

Sunday day hike Rock Creek, Gore Range Silverthorne 13 miles off-trail

Let’s avoid I-70 traffic by going on Sunday! This a 13-mile (3432’ ascent) loop in the Gore Range, above Silverthorne. It’s mostly elk trails (“off trail”). I’ve done it five or six times. The highlights are the ponds and meadows along South Rock Creek and going over the ridge from South Rock Creek to North Rock Creek. Trekking poles are recommended as some sections are steep and there are several creek crossings.

Driving time from Boulder is about two hours each way.

Directions to the trailhead: From I-70 take Exit 205, Silverthorne / Dillon, and travel north on HWY 9 for approximately 7.7 miles. Turn left onto Rock Creek Road (FDR 1350) across from the Blue River Campground. Follow the gravel road for approximately 1.2 miles and turn left at the road marked “Rock Creek”. The winter trailhead parking lot is immediately on your left. Drive up the 4WD road for approximately 1.7 miles to the Rock Creek Trailhead and parking lot.

The Trails Illustrated map is 108.

Rock Scramble of 12ers Mts Neva and Jasper (IPW)

Needs a location

Mts Neva and Jasper are high 12ers in the Indian Peaks wilderness. They are accessible via the 4th of July Trailhead.

Note: Only taking about 10 people on this hike due to group size restrictions in IPW.

Starting at the 4th of July TH, hike up towards Lake Dorothy and start ascending the ridge to Mt Neva. Follow the 3rd class ridge along to Mt Jasper, then descend down back to standard trails.

This hike features nice trails, off trail scrambling and stunning views. Along with "the usual" hiking gear, bring a helmet because we will be scrambling. This hike is not appropriate for people who have a fear exposure.

The total distance is 10 miles with about 3600' of gain.

Meet at Nederland Park n Ride at 6am.
