Beta is the largest, full service indoor bouldering gym in Northern Arizona. We opened our state-of-the-art facility in the Fall of 2012 to provide the growing climbing community a place to train, socialize, and get fit. Our spacious facility was designed specifically for bouldering, meaning the majority of our climbing walls do not require ropes or any complex gear besides rock climbing shoes and a chalk bag. 


At Beta, we strive to provide something for everyone, from the beginner to the hard-core climber. You will learn to set goals, improve your risk-taking skills and increase your mental sharpness, all while training your body and cementing new friendships. To get the most out of your climbing experience, tour our site to see our flexible rates and customized programs for most ages and all skill levels.

Assumption of Risk: Rock climbing involves many risks and dangers that are inherent and integral to the sport. The exercise of good judgment, common sense and the proper use of equipment can help reduce these risks. However, you can do everything right and still be seriously injured, or killed. Please seek professional instruction before attempting this sport. Remember, your safety is your responsibility. The Beta does not require the use of a helmet at the gym, though we do provide them at no charge.
