Junior MAC - Seattle - 2023

Youth Program

Junior MAC

Junior Mountaineers Adventure Club (Jr. MAC) is a year round program for youth ages 12 - 13.


Jr. MAC is a year-round outdoor adventure program for youth ages 12-13 who want to learn new outdoor skills and make lasting friendships with fellow adventurers. The program is designed to expose youth to a variety of outdoor activities, including climbing, hiking, paddling, xc skiing, and more. While both parents/guardians are not required to attend outings, parent/guardian chaperone support is required for all trips (this could be another Jr. MACer's parent/guardian). This is a great opportunity for you to get outside with your Jr. MACer!

We also offer climbing skills sessions and leadership opportunities for the parents! Starting this year, parents will have the opportunity to take part in a climbing skills series, learning what it takes to set up and take down ropes from the top of a climb. We will also be offering a leadership series, providing the tools and guidance in planning and leading trips for the clubs.


Jr. MAC membership is $1100 for families joining in October. Students joining in the winter will be prorated. The standard payment structure will be a single payment of the total amount 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 may make that request upon being offered a place in the club after the lottery. In that case, registration will be handled manually by staff. 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.



For those who were a part of the youth clubs during the 2022-2023 program year, please fill out our enrollment lottery. Anyone wishing to join Jr. MAC must have completed the enrollment lottery, regardless of participation in the clubs for 2021-2022. On September 15 at 12pm, the lottery will close and placement in the club will be offered the following morning. 

 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 per lottery results.


To register for the Jr. MAC Kick-Off Trip, register on the activity page, which is listed as a stand-alone seminar in order to allow prospective members to register themselves. 

Register here for the Kick-Off Trip on Sept 30 - Oct 2, 2022.


We also offer Explorer/Jr. MAC combo trips! These trips are open to both Explorers and Jr. MACers. Combo trips will unfortunately not be visible here on the course page. To see the combo trips offered, check out the Explorers/Jr. MAC Calendar.
