Welcome to the Sierra Club Cimarron Group! 

The largest of Oklahoma’s three regional groups, Cimarron Group is based in Oklahoma City and serves  members in the northwest third of Oklahoma, including the OKC metro, Stillwater, Ponca City, Enid, Weatherford and all the way out to Guymon. Cimarron Group encompasses over 1400 members and communicates regularly with several thousand more supporters. We are all one Club—When you join Sierra Club, you will be a member of the National, State and Local entities. 

Cimarron Group General Meetings

Due to the continuing Covid-19 pandemic, we have decided to extend the current response plans through February 28, 2022 and that includes no general meetings for the time being.  We will continue on the path we launched in July--slowly ramping up small outdoor events & in-person activities in keeping with national guidelines on Covid safety. Please sign up for our enews on the right or check our facebook page to keep informed on smaller, outdoor events and other ways to be involved with our group.
