Organizational Structure

The Mazamas consists of a Board of Directors, staff, and volunteers. 

The board consists of between nine and 13 persons and is elected by the membership. The board is responsible for hiring the Executive Director, who is in turn in charge of hiring and managing the staff. Volunteers hold a variety of roles at the Mazamas, including climb and hike leaders, instructors, class coordinators, and much more. 

Classes & Education

Each year we teach a variety of courses in mountaineering related fields for students of all levels. For most classes, you do not need to be a member, and most classes have lectures open to those who are not in the class.  We offer classes in basic and intermediate mountaineering, advanced rock climbing, advanced snow and beginning ice climbing, ski mountaineering, first aid, nordic skiing, and much more. 

Mountaineering & Climbing

Mountaineering is the primary activity enjoyed by our members. Climbs are open to members who meet the qualifications set by individual leaders. We offer climbs on everything from Mount St. Helens and South Sister to Forbidden Peak.


Hiking is one of the most popular activities of our members, with more than 700 hikes organized each year. In 2017 there were hiking opportunities on 83% of the days of the year! Our hiking program includes moderate hikes, strenuous conditioning hikes, trail tending (work trips), backpacks, snow bivouacs, snowshoe trips, street rambles and short, family-oriented walks around Portland. Most of the hikes are within easy driving distance of Portland, with several offered each weekend, as well as weekday and evening hikes. 

Trail Tending

The Mazamas actively promotes the establishment and maintenance of hiking trails through its trail tending work. Trails such as Trapper Creek, Chetwoot Loop, and Mazama Trail were created by and are regularly maintained by the Mazamas. Mazama Trail Tenders were instrumental in re-opening many trails in the Columbia Gorge which had been hit hard by the devastating storms of early 1996. We expect to be heavily involved in helping the Columbia Gorge recover from the destructive fire of 2017. 

Outings (Travel)

The Mazamas regularly lead travel adventures, both foreign and domestic, that allow our members to experience other cultures, ecosystems, mountain ranges, and the natural world in a safe and affordable manner.  Our travel program is commonly referred to as "Outings" and all travel opportunities are available to members and nonmembers.  Outings are defined as trips that last for five days or more, and may include hikes, walking tours, camping, kayaking, cycling, climbs, etc.


In addition the recreational activities of the Mazamas, conservation is central to the Mazamas’ mission. Since inception, the Mazamas has played a significant role in preserving wilderness areas for posterity. Historically we played a role in establishing Crater Lake and Mt. Rainier as national parks, in the preservation of the Oregon Caves as a national monument, and in setting aside the original 4,000 acres in the city of Portland as Forest Park.

The Mazamas endeavour to maintain a close liaison with officials in all land managing public agencies to insure that the viewpoint of those who access and enjoy outdoor areas is clearly understood by authorities. 

Used Equipment Sale

A used equipment sale is held annually in the spring. This is a great opportunity to find bargains in gear for hiking, camping, climbing and skiing; and a great way to sell surplus outdoor clothing and equipment and support the Mazamas at the same time.
