Rockland County , NY

Nike Overlook Park I and II - Tweed Boulevard - Orangeburg

Situated atop Clausland Mountain, Scenic overviews, picnicking, open play areas, camping overnight for groups by permit and hiking.


Waters from the Palisades flow along Clausland Mountain Road and then south into Sparkill Creek.


The area was named after the Indian, Jans Claus. His Indian name was Tackamack. Claus was a sachem of the Wickquaskeeks with headquarters at Dobbs Ferry, Westchester County. Jan Claus sold about 7,500 acres in 1677 to David Demarest. The land included what is now Oradell, Bergenfield, Dumont and New Milford, New Jersey.

1969  --  Rockland County purchased the land.

early 1970s  --   The Clausland Mountain Preservation Association formed by the Alison family and a group of friends in order to preserve some 450 acres of Clausland Mountain summit from a development proposed at that time.

1981  --  Three small adjoining tracts were acquired in 1981.


The Long Path comes out of the south from the Rockland Cemetery and the path along the ridge to Mt. Nebo, once a Nike missile site.

7/06/02 Parked at Tackamack Park and crossed Clausland Mountain Road following the blue blazes of the Long Path. Descended to cross over a stream on a bridge. Then cross over another stream. Then it was mostly uphill to the top of the mountain. Took the orange trail further up the hill to the old Nike base. It provided a nice change of habitat from the constant woods walk of the Long Path. My wife complained that the walk was boring, but I thought it was alright, even though not the greatest. She was disappointed that there were no views from this walk like most of the other Palisades walks.

Threat to the Area:

Clausland Mountain Preservation Association reports that:

The original seller of this land held back 50 acres of the high summit of this mountain for future development. This land remained in a passive state until just recently when a new developer became involved who would now like to place 18 new luxury homes on this summit. Plans to clear-cut 50 acres on the summit of Clausland Mountain would the mountain's priceless vista for generations to come. There's still a chance to save the mountain - and we need your help!

A builder has captured this property. But thanks to the splendid initiative launched by our colleagues at Scenic Hudson, Inc. and others, $1.5 million dollars has been pledged to purchase this land and convert it to passive park land and open space. But unless the balance of $650,000.00 can be found, development will proceed. . . and that forested area, soon to be covered with roofs, will be lost to you forever.  To help, contact:  Scenic Hudson, Inc./Clausland, Post Office Box 166, Palisades, New York 10964.
