The Climbing Wall Inc. has a new bouldering area; it's one of the larger ones I've seen. The gym also features a separate top roped area with 10 or so top ropes. There's a structurally sound leading area with an overhang. The gym is housed in a warehouse, so there's not much in the way of a/c during the summer. It gets a bit hot, but they're aren't really any other gyms around. I think it's pretty good for Pittsburgh. Rates are $10/day with monthly and yearly rates. Shoes and harness rentals available.
