Climbers negotiate a web of routes that snake up walls that stretch as far as 25 feet toward the roof inside Dyno-Rock Indoor Climbing Center’s cavernous, air-conditioned space. The center sprawls to 16,000 square feet in all, including 2,000 square feet dedicated exclusively to bouldering. Climbers of all stripes will find challenges suited to their skill level, from straightforward routes with large handholds for beginners to inverted ceiling climbs for advanced spider people. The center’s staff also regularly scrambles the routes and handholds to keep climbers on their toes. All first-time visitors must take a quick course that helps them climb confidently, understand gym rules, and ensure a safe experience for everyone in the gym.
