Mountaineers Adventure Club - Seattle - 2024

Youth Program

Mountaineers Adventure Club

The Adventure Club is a year-round outdoor adventure program for youth of ages 14-18.

The Club

The Mountaineers is proud to host an Adventure Club in Seattle and Tacoma. The Adventure Club is a year-round outdoor adventure program for youth of ages 14-18. Currently youth from more than 15 high schools - from Everett to Issaquah and West Seattle to Tacoma - make up our Seattle and Tacoma Clubs. Members meet multiple times monthly to plan outings, learn skills needed to participate, and go on trips. 

The youth members plan all of their outings, with guidance from adult advisers. From single-day outings to week long camping trips, activities have included rock climbing, backcountry skiing, backpacking, hiking, car camping, snow-cave camping, cross-country skiing and mountaineering. While attendance at all meetings and trips is not required, the more meetings and outings you attend, the more you get out of the program!


MAC membership is $2,200 annually for students joining in the fall. Students joining in the winter will be prorated. The standard payment structure will be a 100% up-front payment upon registration. Upon request, members may opt-in to a 4-installment payment plan. This is an annual club.

To join, members must pay the entire course fee on this page when registering. If members wish to opt-in to the payment plan, they will make that request upon being offered a spot after the lottery. In that case, registration will be handled manually by staff in order to bypass the full course fee and begin with installments. Interested members will have the opportunity to join in on at least trip before paying and committing.

We offer financial assistance! To apply for financial assistance click here.




Our registration process is outlined in our enrollment lottery. Anyone wishing to join MAC needs to have completed an enrollment lottery submission. This applies to returning and prospective new members. After families have been notified of lottery results, staff will offer families spots in the program which may be accepted here on this page. 

Here is a video that demonstrates the registration process for individual trips, which will be a helpful reference after accepting your offer to join the club, which will be extended manually by staff according to lottery results. Note: The video shows the Junior MAC course, but the process is the same for all of our youth clubs. 


To register for the Seattle MAC Kick-Off Trip, visit the activity page for that trip which is listed as a stand-alone seminar in order to allow prospective members to register. 

Families who have been awarded a spot through the enrollment lottery will be able to register here for the Kick-Off Trip here, which is September 15th - 17th.
