The secret to this Delaware Riverfront facility's popularity is that it makes rock climbing so stinkin' accessible to beginners, with daily intro classes, friendly staff, and climbing routes more than four stories high. If (when?) you get hooked, enroll in the gym's climbing school, with sessions covering everything from lead climbing to route setting. It's no wonder so many drop-ins become regulars.
