Simply put, there’s no better resource for climbers in Colorado – this outfit is the largest climbing operator in the region, has the most expert guides and is the only organization allowed to operate within Rocky Mountain National Park. It has a clutch of classes taught by world-class instructors.
Basic courses, such as an introduction to rock climbing, are a great way for novices to deeply experience the Rockies. There are multiday training expeditions for those with some experience. Courses are taught in an ideal setting – whether it be a towering granite peak in the park or the 10,000-sq-ft indoor climbing facility in Boulder. You can also stay on-site in dorm lodging ($30).
