Our Vision

Built for Climbers, by Climbers


To foster a welcoming and friendly community of individuals who support each other through our shared passion for rock climbing.


We commit ourselves to providing the highest quality climbing experience possible for every guest by creating a supportive, engaging, and community driven space that welcomes inspiration, diversity, self discovery, and personal achievements.


Onsight Rock Gym was conceived and created with the help of our friends and family with various personal and professional backgrounds, many of whom are avid rock climbers with a lifelong passion and love for the sport. Together, we are committed and passionate in making Onsight Rock Gym a state of the art facility. By working alongside Walltopia, one of the leaders in the climbing wall industry, we have meticulously designed and created a facility we are honored to bring to Knoxville, TN. We have hand-picked our management and development team, who want to share their passion with you. Our love for rock climbing and our dedication to providing you with the best experience possible will resonate throughout the facility - from the warm welcome you receive upon entering the gym to your experience with our friendly, professional staff who aim to motivate and support you through your progress. 

We are bringing you a facility that all of us would be proud to climb at and be a part of. Having been in the sport for more than a decade, we stand behind our expertise and experiences to bring you the best climbing wall design, expert route setting, innovative program development, and above all, an unforgettable experience. We are community focused and driven by our passion for rock climbing to build a gym that will not only be a climbing facility, but a social hub for the ever-growing rock climbing community in Knoxville. We want our gym to be a place you come to build lifelong friendships, set goals, reach new heights, and inspire others. Whether you are an experienced climber or just trying out the sport for the first time, we want you to be part of our community. We are a team of forward thinkers, innovators, and creators, committed to keeping the community motivated, involved, and psyched about rock climbing. We are so excited to share our vision with you and welcome each and every one of you to the Onsight family.
