Dunderberg Mountain and the Timp Hike

Distance: 8 miles
Time: 5.5 - 7 hours (group), 4.5+ - individual
Difficulty: strenuous (over 1500' total elevation gain)

Take the Ramapo-Dunderberg Trail (RD, red blazes) which is found just south of the parking area. The Timp-Torne trail (blue blazes) also starts at the same place on the road but we are only interested in the RD trail for the next few miles.

You will pass the Cornell (blue blazes) and 1777 Trails (red blazes) but continue straight on the RD trail. At the intersection of RD and Timp-Torne (TT, blue blazes) trails at the base of the Timp, follow (veer right onto) the Timp-Torne Trail to go up to the Timp.

The turn-around point the top of the is “The Timp” (with its panoramic views).

Retrace your route from the Timp, veering onto the Timp-Torne Trail (TT, blue blazes). Stay on the TT trail until you reach the road. Your car will be up the road northward (make a left and walk a small distance).Suggested lunch spots are either the top of Bald Mountain or The Timp (better view but later in the hike).

NOTE: The same hike done in the reverse direction is described in The Timp & Bald Mountain hike.

Take the George Washington Bridge to the Palisade Interstate Parkway North, exit at exit 15, turn left (eastward) towards Stony Point (Route 210 East which is also State Route 106 East at this point), at the end of Route 210, turn left onto Route 9W North (if you went straight by accident you would enter a shopping center).

After about 4.4 miles watch carefully for a Dead End sign on the right side that says Jones Point below it. Park in the parking lot on the left side of Route 9W (opposite the Dead End sign/turn-off for Jones Point). You will pass a large ship anchor monument on the right before reaching the parking area (GPS: N 41.28109, W 073.96301).

If you pass the entrance to Bear Mountain State Park, you have gone a few miles too far (turn around and go back south on Route 9W and look carefully on the left for the Dead End sign that says Jones Point below it). The total driving distance from NYC to the trail head is about 44 miles.
