The park entrance road was built in 1767 to bring iron ore from the mines in Hibernia to the iron works in Boonton.

The Morris County Park Service says:

The name "Tourne" is derived from the Dutch word meaning lookout or mountain. The Tourne is the only remaining undeveloped fragment of the Great Boonton Tract, purchased by David Ogden, Colonial Attorney-General of New Jersey in 1759. McCaffrey Lane, which serves as the main entrance to the park, was created in 1767 by Samuel Ogden to haul iron ore from Hibernia's mines to his iron works in Old Boonton. Within this historic region, cannon balls were manufactured for use by the Continental Army during the American Revolution.

Clarence Addington DeCamp (1859-1948) inherited and acquired during his lifetime much of the land now preserved as Tourne County Park. The Park Commission guide to the Tourne describes the history of this trail... Using hand tools and levers, Mr. DeCamp built two roads to the top of the Tourne and encouraged the citizenry to enjoy the forests and fields with him, thereby becoming one of the first conservationists in Morris County.

In 1958 Morris County Park Commission acquired the intial 219 acres from Logan Steele of the Bugbee Corporation and Dr. Lewis Hull. The park was opened for public enjoyment in 1960.


The De Camp Trail takes you to the top of the Tourne. The trail continues down the other side of the Tourne, and returns to the parking lot, for a total of about 1.3 miles. Other trails can be combined for walks of two to three miles.

Follow the entrance road to the last parking lot, where there is a posted trail map. Walk across the road and up the path that passes the rest rooms. Turn left for the DeCamp Trail to the top of the Tourne. There are views at the top in several directions, and it's a good place for a picnic. The NYC city skyline is visible on a clear day. The views also includes a still-rural west outlook toward the Rockaway Valley section of Boonton Township, a more suburban look south toward Parsippany and Morristown, and a view to the east overlooking Boonton. The trail continues down the other side of the Tourne, and returns to the parking lot, for a total of about 1.3 miles. Other trails can be combined for walks of two to three miles.

Among the interesting features is the Mouse Cradle Balancing Rock, a glacial erratic which rests on the southwestern summit of the Tourne and is balanced on two points of ledge rock and a hidden wedge stone. This imposing 54 ton boulder was named by Mr. DeCamp in 1897, when he discovered a mouse nest in a cleft of the rock. He adjusted the boulder with jack screws so the rock could be tilted a few inches with a lever when a hidden wedge was removed.

Here is the Emilie K. Hammond Wildflower Trail. It is a mile of winding paths through varied terrain where you can learn about woodland flowers and ferns native to the eastern United States. Over 200 wildflowers and shrubs. Named after the botanist Emilie K. Hammond, who aided in its development with the cooperation of local garden clubs, the trail is easily reached by entering the Tourne at Powerville Road.
