"Jamaica Bay is part of the Gateway National Recreation Area, a major urban wildlife refuge on 9,155 acres of salt marsh, upland field and woods, fresh and brackish ponds, and a massive bay full of small islands. The park is home to hundreds of bird species, rare coastal flora, over sixty butterfly species, and nearly fifty species of fish. The bay is located at the confluence of several estuaries, contributing to the ecological richness and diversity of the area.
This is a fairly flat ride on mostly car-free bikeways through a beautiful section of Brooklyn and Queens, near the JFK airport. Starting at Canarsie Pier, the trailhead is just before the entrance, extending left and right. Facing the park entrance and sign, turn left, heading northeast, to begin the ride. This portion of the trail runs parallel to the Shore Parkway, separated by a wide grassy median and highway railings on the left. The trail makes three scenic bridge crossings in a row, leaving Brooklyn into Queens on the final crossing, overlooking the Old Mill Creek on the right."
