Officially named the Jacqueline Kennedy Onassis Reservoir in 1994, the Reservoir is famed for the 1.58 mile track that encircles the 106-acre body of water. It covers approximately 1/8th of the park and holds over a billion gallons of water.
The Reservoir offers runners one of the best views of the city skyline, and it also allows birdwatchers a great location in which to spot herons, egrets, coots, and loons.
