If you're exhausted from your journey and need a good spot to simply lay on your backs and watch the stars, wander down to the Hester St. Playgroundtrack by Canal Street. Chill AF on summer nights.
This is a large play area with sections for the smallest kids up to basketball and handball courts. If you took a long trip with kids to get to Grand St, this is a good spot to let them unwind.
On Jan 26th, join HSC to celebrate the New Year at their annual Lunar New Year Party! For children and adult activities: http://hesterstreet.org/2011/12/08/lunar-new-year-party
Best playground?! This one is disgustingly dirty. Litter and garbage everywhere. Not as bad as the other playgrounds north of it in Sara Delano park, but absolutely stay away.
