Celebrate Earth Day by helping to keep Liberty State Park clean. We will walk along the beach and clean-up any trash that has come ashore. Please dress to work outdoors, wear old shoes that can get wet and muddy, and bring work gloves if you have them. The program will begin at the Nature Interpretive Center on Freedom Way. Parking is available in the lot across the street from the building. For more information or to register, please call 201-915-3400 x202 or email LSPNatureCenter@dep.nj.gov.
