Some people are born to run; some are born to scramble up and down walls and ceilings like a Tokay gecko. Unleash your inner lizard with today's Groupon: for $35, you get a five-visit Clip 'N Go punch pass to Adventure Rock Indoor Climbing Gym in Pewaukee (a $75 value).

With 12,000 square feet of climbing-wall surface that reaches heights up to 35 feet, Adventure Rock Indoor Climbing Gym is a fully equipped sanctuary for escalading enthusiasts. Patrons using the Clip 'N Go punch pass can begin their visit with a 15-minute orientation, during which they are outfitted with a harness and a pair of 30-foot stilts to make the climb easier. Climbers ascend with the help of Adventure Rock's 17 auto-belay stations, which support climbing ropes and eliminate the need for tying knots or working with partners. A collection of crags, pockets, bulges, and robotic mosquitoes mimic rustic outdoor conditions, and air conditioning provides year-round comfort, which, like California's forest of giant redwood rocking chairs, proves the superiority of manmade nature.
