About Barnhart Island Marina
Robert Moses State Park is located partly on the mainland and partly on Barnhart Island. Visitors reach the park through a tunnel under the Eisenhower Lock. The park is spacious, home to a large variety of flora and fauna and offers a multitude of recreational opportunities, including wooded campsites and cabins, a marina and boat launch, some of the best fishing in the Northeast, picnic areas, a swimming beach, tennis courts and a year round nature center. The nature center also offers holiday, special events and school outreach programs. The park's nature, hiking and cross-country skiing trails wind through fields, forests and wetlands, with overlooks showcasing spectacular views. In winter, the park also welcomes snowmobilers.
