Safety is at the core of our business. We outfit climbers with mandatory helmets, harnesses, safety glasses, foot holds and ascenders, all of which meet international climbing standards of the International Climbing and Mountaineering Federation (UIAA). We comply with Tree Climber's International standards.
Since the founding of recreational tree climbing in early 1980’s, there have been no known serious accidents or death from recreational tree climbing in more than 30 years with proper equipment, protocols, and while under supervision of an instructor. Simply stated, recreational tree climbing is amazingly safe. As long as you follow the basic rules, protocols and have the right equipment, tree climbing is far safer than most daily activities like riding a bike.
It is the goal of our tree climbing program to go above and beyond the standards. For example, the American National Standards Institute has requirements that arborist rope have a minimum breaking strength of 5,000 pounds, while all of our ropes are rated to at least 6,000-12,000 pounds of breaking strength. All of our climbing systems and anchors are also redundant, which is an extra and uncommon safety feature of only our program.
We are currently hiring for tree canopy climbing and rock climbing guides for our 2020 season. If you would like more information about positions please email
