At the dawn of the world, everyone rock-climb-commuted to work. It was only after the invention of falling, however, that rock climbing became thrilling, sexy, and glamorous. Today's Groupon invites you to live the life of a rock star: for $25, you get a two-week unlimited pass, including all rentals and a safety lesson for first-timers, at Climb Kalamazoo (a $50 value).

Open 365 days a year, Southwest Michigan’s premier climbing gym functions as a 10,500-square-foot climber’s sanctuary. The state-of-the-art climbing center, which touts 30-foot walls and routes up to 65 feet in length, offers beginning belayers and skilled shale shimmiers alike the chance to reach the summit of impressive rock formations. Using hands and prehensile carabiners, climbers support their own weight and engage upper and lower body muscles for the ultimate endurance test. Whether pass holders are aiming to enhance current scaling skills or aspiring to rescue a few more tree-cats this season, Climb Kalamazoo can satisfy desires in a safe, comprehensive manner.
