Trails to Try

A Little History

The Tourne is the last undeveloped piece of the Great Boonton Tract, land bought in 1759 by David Ogden, colonial New Jersey's attorney general. Clarence Addington DeCamp (1859–1948) later inherited and acquired much of what is now the park, built roads to the summit using hand tools, and invited neighbors on hikes, earning a reputation as one of the county's first conservationists. The Morris County Park Commission bought its first parcel on July 24, 1958, and opened the park to the public in 1960.
