Volunteers may register for the event via our Eventbrite listing (forthcoming). Volunteers will pick up/ rake litter located around the mosaic benches lining Grant's Tomb, pick up trash and litter in the surrounding area, and remove weeds from nearby trees. The cleanup will take place over the course of 2.5 hours and will include a tour of the Memorial given by a National Park Service Ranger. The National Parks of New York Harbor and Riverside Park Conservancy look forward to working with you!
