In the Fall of 2016, we started our inaugural High School Climbing League for students in grades 9 - 12 at Onsight Rock Gym. We are Knoxville’s premier, full-sized, one hundred percent climber-built gym. Our facility offers 50+ foot high lead climbing walls and has a diverse layout of top roping, lead climbing, and bouldering. With more than 12,000 square feet of climbing surface, students will never run out of new routes and boulder problems to climb and practice on. We employ professional route setters who create fun and challenging climbs that cater to all levels of climbing (from 5.6 to 5.13). Our bouldering area features 15 foot high angled bouldering walls with over 18 inches of seamless padding to cushion falls. We also offer fitness and yoga classes weekly and have a climbing specific training area.

Purpose: The High School Climbing League is designed to introduce high school age students to a team sport that emphasizes teamwork while fostering personal growth and the foundation for a healthy lifestyle. Climbing provides a fun physical challenge in a safe environment where students will be inspired to explore their personal best with the support of their teammates.

The lessons learned in rock climbing can and do apply to all other areas of life, and can have a profound impact on the lives of some of your students! Climbing teaches discipline; it shows students how to self-monitor and will improve their overall confidence. Rock climbing also teaches team dynamics very effectively. Climbers quickly realize that, through the belay partner process and the encouragement/support factor, they have to trust and work cohesively with others if any significant goal is to be achieved.  Consequently, climbing provides a positive avenue for overall self-improvement and character building!  In addition, rock climbing has the potential to appeal to those fringe students who may not feel like they fit into other extra-curricular activities, or simply may not have the abilities or the skills to make it onto the mainstream sports teams, but still would benefit greatly from pursuing an athletic endeavor.
