South Mountain Reservation, covering 2,110, 2,112, 2,000, 2,100, or 2,047 acres (8.539, 8.546, 8.094, 8.498, or 8.284 km2) depending on who you ask, is a nature reserve on the Rahway River that is part of the Essex County Park System in northeastern New Jersey. It is located in central Essex County, New Jersey within portions of Maplewood, Millburn, and West Orange. It borders South Orange between the first and second ridges of the Watchung Mountains. Carved from wilderness at the end of the 19th century, designed by Olmsted Brothers, and developed over a few decades, the reservation has changed only slightly through the years. Preserved primarily in its wild state, woodlands abound in a variety of hardwood trees, and tall hemlocks tower above streams, creeks and ponds, and waterfalls. Higher points, such as Crater View, offer vistas of the New York and Jersey City skylines, Elizabeth, Union Township, and Staten Island. Recreational complex Richard J. Codey Arena and Turtle Back Zoo are located within the reservation's boundaries. The recreation area was expanded to include Safari Minigolf and the Treetop Adventure Ropes Course in 2010, and McLoone's Boathouse Restaurant abutting the Orange Reservoir was added in 2011. In 2013, a paddleboat concession was added, accessible from Cherry Lane, across from the Oakdale Picnic Area, and paths from the restaurant and zoo. Orange Reservoir Orange Reservoir is a reservoir located in the reservation's northern tract. Within the borders of West Orange, it is owned by the City of Orange and operated and maintained under contract with United Water. It was originally developed during the intense urbanization of northeastern New Jersey in the late 19th century, drawing from the Rahway River. The man-made lake is no longer part of the water-supply system and since the late 2000s (decade) various proposals have been made to allow its use as a recreational resource as part of the Recreational Complex. The complex abutting the reservoir includes a miniature golf course, and a boathouse-restaurant opened in 2011. Proposals were complicated by the fact that while owned by one municipality, it lies within the borders of another, and it is unclear whether it is taxable. Offers by the Essex County Park System to buy or lease property were put in place as a possible resolution. The county was able to reach an agreement to lease the reservoir from the City of Orange until 2032. In November 2013 it
