I saw the Groupon offer & I loved it. This was my first time experiencing this so I thought it was fun & it was also a bit of a workout for me. The small walls (or bouldering) were a nice warm up & it made me realize my upper body strength is at an all time minimum. They have the walls color coded and labeled to let you know if it's considered easy or challenging. The amazing part was the huge wall climbing that is something everyone should experience at least once.
