About the GOTC

Founded in 2007, the Global Organization of Tree Climbers has members, recognized facilitators, and recognized instructors around the world.

The GOTC supports recreational and professionals in the following areas:

  • Promoting safe practices for rope and harness tree climbing.
  • Providing learning opportunities and services for individual climbers.
  • Increasing access for tree climbing.
  • Facilitating professional growth and accreditation for instructors and program leaders.
  • Forging links with outdoor experiential organizations and the public.
  • Fostering wilderness, environmental and climber ethics.

Our signature event, the Tree Climbers Rendezvous, is held in different locations across the US and worldwide each year, working together with local organizers. This unique event brings new and old climbers together to share, learn, network, and have fun in the trees.

In 2007 a group of some of the most experienced tree climbing instructors and facilitators came together with the goal of creating an inclusive, non-profit, and democratic organization to serve our growing community. From that initial meeting arose the Global Organization of Tree Climbers, an organization dedicated to serving the recreational, adventure, experiential and educational tree climbing communities.
