There are a few ways of joining…

Membership allows you to borrow gear from our gear shed for mailing-list-announced trips, borrow books and maps from our library, subscribe to our email list, organize and attend trips. Membership is open to the general public — association with UC Berkeley is not required! And it’s only $10 per year!

By Mail

If you can’t make it to a meeting, you can still join by mail! Send us a letter with your

  • Name
  • Email address, and
  • University Affiliation, if any (Undergraduate, Graduate, Postdoc / Faculty / Staff, None / Community Member)

along with a check for $10 made out to “ASUC / CHAOS” to:

CHAOS
P.O. Box 4354
Berkeley, CA 94704
United States

Note: please don’t mail cash! It tends to disappear before it gets to us.

In Person Easiest!

CHAOS has weekly meetings in the courtyard outside of La Val’s Pizza and La Burrita in Northside Berkeley. While meetings are certainly not mandatory, they’re a great opportunity to hang out with CHAOS members, grab dinner and a drink, and chat about the outdoors!

Meetings happen every Wednesday at 7:30pm, rain or shine, 52 weeks a year. Talk to an officer at the meeting to join! (Don’t forget to bring $10, cash, or check made out to “ASUC / CHAOS”)

Online

We currently do not support online sign-ups, but we’re working on making it available as soon as possible. Keep an eye out!
