Phoenix Rock Gym

Phoenix Rock Gym's personable owner Paul "Dief" Diefenderfer has been scaling the big buttes around Arizona for 30 years -- he favors Pinnacle Peak and the giant domes of Cochise Stronghold near Tucson -- and he designed his indoor rock gym, now situated just across from the APS power plant on University Drive in Tempe, as a small-scale replica of his favorite canyons, cliffs, crags and crevices.

Phoenix Rock Gym was the first indoor climbing facility in the state, and still carries the most cred with the outdoor extremists. On weeknights, once the kids have cleared out, the 15,000-square-foot mini-canyon is filled with Dief's pro bouldering buddies. But the 17-foot overhang in the spacious beginners' area is designed to bring home the thrill of the big-time climb to the lil' lowlanders. "The kids love it, 'cause when you fall, you kind of swing out, and go for a ride," Dief says. "As long as you've got a rope on, falling is fun!"
