This review is from my 9 year old grandson. He loves going to Rocktopia in the Encore Gym in Concord to climb on the climbing wall. The staff is great and you can be sure all safety precautions are being taken care of. They strap you into a safety harness and there are two adults nearby at all times. It seems like a great place to have a party. We see large groups everytime we have gone in. My grandson is fearless, but this wall is high and even he was a bit nervous at first. Now, after a few sessions, he is eager to try more and more challenging walls. We’ll see. For now, this is a fun and safe place to go and have a neat experience you can’t get everyday. The price is good too!
