This is the only Rock Climbing gym I've been to so my review might be a bit biased.
The gym itself is very nice. A bunch of walls with all kinds of paths to take. I usually grab on to whatever rock I can reach. The next time I go I will try sticking to paths. They recently created a bouldering wall on the second level but that is only available to members. They do have a small bouldering section in the back corner that is available to everyone. A lot of the walls/ climbs require two people. One person that is climbing and the other is belaying. If you go in by yourself, you're kind of limited to the auto-belay climbs (I believe there are 4) and the bouldering section.
The overall price for rental and day pass is around $17-20. If you do plan on going there more than twice in a month, I highly suggest you sign up for their membership which is $35 and you can go as many times you want through out the month. Plus you get access to the upstairs bouldering room.
