A few months ago, I discovered an amazing program at Chelsea Piers for my son who is 6 years old. It is called Rock-N-Rolls and consists of 45 minutes of rock climbing and 45 minutes of gymnastics. He gets to do his two favorite activities in one 90-minute session! My son loves the  colossal foam pit and racing his friends to the top of the rock-climbing wall. He talks about the Rock-N-Rolls class for weeks after he goes and can't wait to go back!
