The High Line was already one of our favorite outdoor places in New York City. Now it’s gotten better: The 1.45 mile promenade, built on a stretch of elevated railroad track on Manhattan’s West Side, has added an outdoor roller-skating rink. The High Line Rink–some 8,000 square feet of skating space at West 30th Street and 10th Avenue –will be open only through Monday, September 26. Hours are 11 a.m. to 10 p.m. Sunday through Wednesday, and 11 a.m. to 11 p.m. Thursday through Saturday. Regular admission is $10 for children under age 13 and $12 for adults, which includes rental skates (you can bring your own, but there’s no discount). Children under age 13 must be accompanied by an adult, but the rink waves the admission fee for non-skating parents or guardians. You can bring your own snacks or treat the kids to something from the food trucks. The High Line posts a note about which trucks are going to be near the rink every day here.
