Backpacking Building Blocks (B3) Course - Foothills - 2025

Backpacking Course

Backpacking Building Blocks (B3) Course

Jump-start your backpacking dreams with the Backpacking Building Blocks (B3) course, sponsored by The Mountaineers Foothills branch. In it's 13th successful year, this comprehensive season-long course supplements basic gear and skills lectures, gear demonstration and practice, with mentor groups to give you season-long support and community, and optional seminars to help you 'dig deeper' in areas like ultralight gear, food planning and prep, tips for women, trip planning, navigation and more. Whether you're a new or returning backpacker, we'll give you the knowledge and skills to become capable and confident on overnight or longer trips with the club or on your own. Open to members from any Mountaineers branch! PRE-REQUISITE: To register for B3, you must be comfortable day-hiking at least 5-miles and 1000 feet of elevation gain on a typical backcountry trail (uneven surface with roots, rocks, mud, steep gravelly slopes, fallen logs, sometimes water crossings) at a pace of at least 1.5 miles per hour, carrying at least a day-pack. If you aren't already comfortable with this type of hike, so we'd encourage you to start with the Mountaineers GoHike course, focused on helping beginners build hiking and trail experience starting with easy trails and building up. Then you can take your newfound trail skills into B3 in 2026!

PREREQUISITE:  

To register for B3, you must have prior experience day-hiking at least 5-miles and 1000 feet of elevation gain on a typical backcountry trail (uneven surface with roots, rocks, mud, steep gravelly slopes, fallen logs, sometimes water crossings) at a pace of at least 1.5 miles per hour, carrying at least a day-pack. If you aren't already comfortable with this type of hike, so we'd encourage you to start with the Mountaineers GoHike course, focused on helping beginners build hiking and trail experience starting with easy trails and building up. Then you can take your newfound trail skills into B3 in 2026!

REGISTERING FOR B3:

AT THE TIME YOU REGISTER FOR THE B3 COURSE, PLEASE ALSO REGISTER FOR THE REQUIRED "BASICS" LECTURES AND DEMO DAY.  WE ALSO ALSO ENCOURAGE YOU TO REGISTER IN ADVANCE FOR  ANY OF THE OPTIONAL  SEMINARS OR CLINICS YOU ARE INTERESTED IN.  

  • At your earliest convenience after registering for the course, please complete and submit the required mentor group information form to help us tailor the course to our students' needs and inform your mentors of your interests, priorities and background.  
    • This form MUST be completed by no later than Feb 28 or you will lose your spot in the course, even if you don't care about being in a mentor group.  The form will be easiest to complete on a tablet or computer, more clunky on a smartphone, though certainly can complete either way.
  • If you absolutely can't attend one of the four required components, email Cheryl Talbert at cascadehiker12@gmail.com  and we'll discuss your options to get that information or experience another way - we're here for you and know that schedules can be crazy!
  • If  you can't commit to one of the seminars or clinics shown within the course listing at the time you register for the B3 course, you may come back and register later if space is available by opening the B3 course listing, scrolling down, and clicking on Manage My Registration.  Space is limited so reserve your spot as soon as you can.  Students will also have access to recordings of the lectures and seminars after they are held - but you'll want to attend in person if you can so that you can get involved in Q&A and breakout discussions.

B3 GRADUATION REQUIREMENTS:

To graduate, students must complete all of the four required components plus 3 backpack trips {of which at least one is two nights or more}.   

  • Any Mountaineers backpack trip including B3 student-only backpacks and mentor group backpacks count, as do Mountaineers overnights for the scramble course! 
  • One of the three backpack trips can be a private trip as long as the student does the primary planning, supplies and carries their own gear, sets up their own camp and plans-carries-prepares their own trail food; the other two can be any Mountaineers-led backpack. 

To graduate we also ask that you complete the free online Low Impact Recreation course offered by the Mountaineers, and at least one stewardship activity.

  • Stewardship trips are available in quantity on the Washington Trails Association and Mountaineers websites and are easy to get onto but you must register!  You may complete your stewardship even before the first course lecture if you'd like, and stewardship activities completed in the past 6 months for other courses can count.

YOU MUST SIGN UP FOR TRIPS, GET YOUR LOW-IMPACT RECREATION BADGE AND COMPLETE A STEWARDSHIP ACTIVITY TO GRADUATE FROM THE COURSE! 

  • You have as many years as you need to complete the requirements without having to retake the course.

GROUP BACKPACK TRIPS!

Beginning in the early spring, a range of exciting backpacking trips from overnights to 5 days or more led by our amazing volunteer leaders will be offered  on the backpacking activity page  of the Mountaineers website.  You'll find trips ranging from easy to challenging, and these trips will help you expand your backpacking skills and confidence, and introduce you to our favorite places in the amazing PNW backcountry with experienced Mountaineers leaders and trail companions you will come to know and trust.  

  • These trips are open to all qualified Mountaineers members, but we'll show you how to get on an email list so that you find out about new and interesting trips as soon as they are listed!

Required Equipment

Students will need to have at east a basic backpacking gear kit to go on backpacking trips - The Mountaineers do not provide gear.   A suggested gear list will be provided to students in advance of the start of the course as well as a set of resources for finding good gear at a discount.   We will provide lots of support and guidance during the course to help you choose the gear that suits your needs, objectives and budget.  You are very welcome to use whatever gear you already have. or to borrow or rent gear, until you have an idea of what you want.  A basic gear starter kit could be bought for $500 or possibly less if you're willing to purchase gently used and/or heavier items from non-name brands, though you could spend $2000 or more for a full set of lightweight name brand gear.

To go on backpack trips you will need your ten essentials plus a tent or other shelter, sleeping bag or quilt and pad, basic stove or cooking system and mug, bowl and spoon, a way of carrying water for the trail, basic water treatment, an overnight pack (usually approx 50-60L), hiking shoes or boots, raingear and both hiking and overnight clothing.  Other gear may be required for specific trips.
