outside climbing classes
For some, climbing is on the bucket-list, a taste of adventure or just a fun afternoon. For others—it’s a lifelong pursuit of movement, problem-solving, and adventure. Whether you're drawn to local crags, towering cliffs, or far-off mountain ranges, every climber follows their own path.

Prerequisites: none!
Dates: 2.5 days - May 29-31, 2026
As the opening course in our series, we will take you through the basics of equipment, harnesses, safety checks, tying the figure 8 knot, using the GriGri and ATC, belaying and basic outdoor climbing tips such as following a climbing route, identifying good and not-so-good rock, mastering smearing, using your feet effectively, and straightening your arms. We do ask that you bring your own shoes, harness, belay device and helmet, although we can lend you some of it if you ask ahead of time. Whether you're brand new to climbing or looking to brush up on your skills, this Intro to Outside is perfect for anyone ready to take their climbing outdoors!
Looking for a Family-Friendly way to learn the ropes? If an adult registers for our Intro to Climbing Outside course, they can add a dependent (age 7-13) for just $150 to learn alongside them! Parents will gain hands-on experience setting up climbs, identifying safe top-rope areas, and belaying, while kids learn to harness up, tie in, and everyone gets to climb! Ages 12+ can also learn to belay with a similar-weight partner, and teens 14+ should register for the full course themselves. It’s the perfect way to build skills and confidence together in the great outdoors!
Price: $200 Member, $250 non-member

These are not registered or certification level courses, and are offered only as a way to grow your knowledge and safety when climbing outside. They do not certify you to instruct others. Please bring your own gear to all classes: harness, belay device, helmet, and shoes. If you do not have a piece of equipment, please let Stonetree or your instructor know before your class begins, and we will do our best to find you some loaner equipment.
These classes require a minimum of 4 participants. If there are less than 4 participants 5 days before the start of class, we will have to cancel with a full refund to participants. Alternatively, if you have your own group of 4 that are interested in a special session of ANY of these courses, we’d be happy to build a custom course for you based on the availability of our instructors.
If you have to cancel your booking, please see our Cancellation Policy. Any other questions, don’t hesitate to ask.
Why Outside?
We all start somewhere—tying in for that first top rope climb, learning to trust the rope, and feeling the exhilaration of moving on real rock. From there, the journey may unfold in any direction: stepping into lead climbing, managing our own protection, and perhaps falling in love with the elegant lines of traditional climbing. Maybe it’s the aesthetic of granite cracks, the lure of alpine summits, or simply the desire to climb farther, higher, and with greater independence. Wherever your path leads, one thing is certain—gaining the skills to climb confidently and safely unlocks new possibilities. Stonetree’s outdoor climbing classes are designed to guide you through this progression, giving you the tools to explore, push your limits, and develop true self-reliance.
This is your journey. Let’s take it outside.

Haven Hoffman
A Helena-valley local and an American Mountain Guide Association certified Single Pitch Instructor with 10+ years of climbing experience. Before becoming a bona fide trad dad, he spent nearly a decade working as a shipboard maritime engineer where the only thing to climb was heavy equipment and Abrams tanks. With experience climbing around North America, from grain silos in Indiana to multi-pitch ice in the South Fork of the Shoshone, he’ll be glad to share his knowledge with you, and we're psyched to have him as a part of Stonetree.
