Fun for all ages! Went here today (using their Groupon) for the first time and had a blast. Took about 20 minutes to watch a safety video, learn the harnesses, etc. and then you were free to climb as you please. I highly recommend going in pairs or else you will have limited options of ropes or need to have a stranger that you can pair up with. However, I saw two auto hookups where you could just climb on your own. Climbs are labeled by difficulty so you have a heads up what you're getting yourself into.
Got there around 3 on a Saturday and it was pretty crowded. Most ropes were in use. However by 4pm there weren't many people there. I would recommend going early or later on in the day. Will definitely be back.
