We love a good spooky theme—and good thing, because this year’s Halloween Harvest Festival theme is Día de los Muertos! There will be a performance by Ballet Folklórico Mexicano de Nueva York, and the opportunity to add personal mementos to ancestral altars set up throughout the park. Shaman Mama Donna will be on site giving harvest blessings to pets. Pooches are welcome of course, for the annual Canine Costume Contest. All ages.
