Good rock climbers use technique and strength to scale cliffs, but great rock climbers simply use their anchors to poke the cliff until it lays down on its side. Practice mastering a cliff with today's Groupon to Rockhaus Indoor Climbing Gym in North Logan. Choose between the following options:

• For $7, you get a one-day pass (up to a $14 value).
• For $29, you get a one-month membership (a $69 value).

Veterans and novices alike discover plenty of routes and challenges at Rockhaus Indoor Climbing Gym, where 12,000 square feet of bouldering, lead climbing, and top-roping areas create a wall-hugger's paradise replete with arêtes and cracks. After strapping on a harness and calibrating the belay device, climbers squeeze into a pair of shoes and begin dragging themselves toward a cloudy summit using the wall's colorful, candy-flavored studs. Hone complex moves and problem-solving skills in Rockhaus's bouldering area; or, if you enjoy vertical zipline rides, head over to the rappel ledge to practice free falling with a rope. Harnesses and belay devices are included in the deal, although customers will need to bring along their own shoes or rent a pair from Rockhaus ($3).
