The Mazamas roots are in mountaineering. Founded on the summit of Mt. Hood in 1894, we have been reaching summits for well over a century. We offer a variety of mountaineering opportunities through the year with the bulk of our climbs being offered from April–October.
You'll find climbs of Mt. Hood, Mt. St. Helens, Mt. Adams, the Sisters, and so much more! On the right hand side of this page you will see upcoming climbs on the calendar. You can view the entire lineup of upcoming climbs by clicking the calendar link at the top of the page and applying the Climb filter.
The foundation of our climbing program is to be a service to our climbers and the community, provide climbing education, experience, and fun.
