Great for Students and the Community.
The Gym available at the University of Pennsylvania is not only open to students of the school, but to all members of the surrounding area. The five dollar day pass makes this one of the cheapest in Philadelphia rock climbing. For those who find themselves in love with the sport, there's also a year pass available for a cool hundred bucks.
