Roller Skate Circle is used only on Saturday, Sunday and holidays. You can get there walking from 72nd Street Station on your way to Bethesda Terrace. Staffs in purple T-shirts run roller skate circle from 14:30 to 18:30 on Satruday, Sunday and holidays. Lots of sightseeing tourists gather there. Everyone can roller skate. Children are required to wear helmets. It is one of the most interesting spots in New York. I have found the homepage of Central Park Dance Skaters Association.
