The extreme center is basically composed of a basketball court, tennis court and many other activities. The center has many great activities that are not apparent unless you ask. These include roller skating, archery, ping-pong, bicycle riding, rock climbing and many others. I attempted to try most. Basketball was a favorite of our family and we played it multiple days during our stay. Some family members opted to go bicycle riding and others tried archery. None tried the rock climbing. I contemplated doing it but never got the nerve to do it. The archery was a lot of fun. At first you feel apprehensive, but once you get the hang of it, you are hooked and do not want to put the bow down. Now this setup is not professional in any way and is inviting. I notice that very few hotel guests took advantage of this amenity as most stay absorbing the main attraction; the sun, pool, beach and food. Getting a break from doing nothing is sometimes healthy and very enjoyable. I highly recommed trying some of the activities I mentioned if you stay at the Hard Rock in Punta Cana.
