Mt. Tammany makes up the New Jersey side of the Delaware Water Gap. It is a very popular mountain for people from the NY, NJ, and PA area. Also the Appalachian Trail runs in the valley next to it so during the summer months you can meet a through hiker or two on almost everyday, I usually do when ever I am there. There are 3 trails to the summit: The Red Dot Trail, Blue Dot Trail, and The Mt. Tammany Fire Road. Besides trails there are many climbing routes on the cliffs that are on the south and east faces making Mt. Tammany a very popular mountain for climbers. Here is some info from on Mt. Tammany There are also some good scrambles to the top on the east side. It is the closest thing to a real mountain in NJ that I have done and I live in NJ.
Also check out the Mt. Minsi Page. for info on the P.A. side of the "Gap".


Tammany refers to Chief Tamenend.

1683 (June 23): William Penn and Delaware Chief Tamenend signed a peace treaty in Shackamoxon, Pennsylvania. Tamenend renown for his honor, was also called Tammany. (Tammany societies were named in his honor.) The treaty gave William Penn a large portion of land. Thank You Google.

Natural features:

Sunfish Pond - High on top of the Kittatinny Ridge is a blue lake, Sunfish Pond, a relic of the Wisconsin Glacier (which gouged out a hollow that later filled with water) around 18,000 years ago.


In 1870 Sunfish Pond was described as "a sheet of pure transparent water . . . strangely and unaccountably situated on the very Summit of the mountain." (quoted in Pepper 1965:158)

1903 -- millionaire businessman Charles C. Worthington, president of the Worthington Pump Corporation, acquires 8,000 acres on both sides of the river in the Delaware Valley. He erected a small mansion (called Buckwood Lodge) on a hillside half way between the river and Sunfish Pond (which supplied the water for the mansion). At that time, he called the pond: Buckwood Lake.

Worthington used the state forest area as a deer preserve for hunting.

Dunnfield Creek- Dunnfield Creek is a natural trout stream with deep ravines. The Dunnfield Creek Trail can be combined with the Appalachian Trail for a nice loop.


New Jersey- Take 80 East to Columbia, New Jersey( exit #4) their is a bunch of fast food places right off the interstate that includes: MacDonalds, Taco Bell and Pizza Hut.
P.A.- Take 80 West and exit at the first exit and follow signs for the town of Water Gap, PA. their are a few resturants in the town.


Supplies / Gear:

PA- The nearest outfitter is the Pack Shack in the town of Water Gap. To get to it take the first exit in P.A. and follow the road into town it is on your right.
New Jersey- The nearest outfitter in NJ that I know about is Ramsey Outdoor Store In Ledgewood NJ, about 30 miles away on 80 East.

Getting There

It is the easiest mountain to get to, i think, in the world. It is right next to I-80. It is good for accibility but bad for the noise, you can hear the 18-wheelers all the time.
From I-80 east get off on the first Exit in NJ and park at the Infromation center on your Right and go hiking.
From I-80 west get off at the second to last exit in NJ and park. the trails start from the end of the parking lot.
