Fort Monmouth is a former installation of the Department of the Army in Monmouth County, New Jersey. The post is surrounded by the communities of Eatontown, Tinton Falls and Oceanport, New Jersey, and is located about 5 miles from the Atlantic Ocean. The post covers nearly 1,126 acres (4.56 km²) of land, from the Shrewsbury River on the east, to Route 35 on the west; this area is referred to as 'Main Post'. A separate area (Camp Charles Wood) to the west includes post housing, a golf course, and additional office and laboratory facilities. A rail line, owned by Conrail, runs through Camp Charles Wood and out to Naval Weapons Station Earle. The post is like a small town, including a Post Exchange (PX), health clinic, gas station and other amentities.
