. Though the US National Park Service manages the National Recreation Area, portions of the water gap are also patrolled by New Jersey Division of Parks and Forestry. The park does not charge an entrance fee but does have expanded amenity fees, including vehicle season and daily passes, bicycles amenity fees, and charges for beach use. Most of the park is open 24-hours a day, with most day-use areas within the park open sunrise to sunset (such as trailhead parking lots, Millbrook Village, and all picnic areas).


Geology

A water gap is a geological feature where a river cuts through a mountain ridge. The Delaware Water Gap formed 500
million years ago Million years ago, abbreviated as Mya, Myr (megayear) or Ma (megaannum), is a unit of time equal to (i.e. years), or approximately 31.6 teraseconds. Usage Myr is in common use in fields such as Earth science and cosmology. Myr is also used w ...
when quartz pebbles from mountains in the area were deposited in a shallow sea. The Martinsburg Shale on the eastern side of what was to be Kittatinny Mountain was uplifted 450 million years ago when a chain of volcanic islands collided with proto-North America. These islands slid over the North American plate, and deposited rock on top of the plate, forming the Highlands and Kittatinny Valley. About 400 million years ago, a small continent collided with proto-North America. The heat from the pressure melted the quartzite, which allowed it to bend the quartz pebbles. This layer was then uplifted and cracked over thousands of years. During this period, the Delaware River slowly cut its path down through the shattered and cracked quartzite. If the quartzite had not been cracked, the river would not have been able to cut its path through the mountain to form the gap. Millions of years of rain, ice, snow, and wind erosion shaped the area.

Martinsburg shale. Sedimentary rock is along the river. The Bloomsburg Red Beds, a red shale, are at the gap under Dunnfield Creek. The Delaware Water Gap is nearly wide at river level and about wide from the top of Mt. Tammany to the top of Mt. Minsi. It is more than from mountaintop to the river surface. The river through the gap is above sea level. The ridge of the Appalachians that the Delaware River crosses is called the Blue Mountains in Pennsylvania and the Kittatinny Ridge in Warren County, New Jersey. This is the first major ridge of the Appalachian mountains. New Jersey's mountain is Mount Tammany, named after the Lenni-Lenape Chief Tamanend. The Pennsylvania mountain is Mount Minsi, named after the

Transportation

Steep rock walls prohibited foot travel through the gap until a road was built on the Pennsylvania side of the river in 1793. In 1830, a road was built on the New Jersey side through the gap and north toward Pahaquarry. Interstate 80 passes through the gap on the New Jersey side as of the early 1970s via the Delaware Water Gap Toll Bridge, and occupies the former right-of-way of the New York, Susquehanna and Western Railway. The Pennsylvania portion of the New Jersey Cut-Off mainline of the Delaware, Lackawanna and Western Railroad comes into Slateford, Pennsylvania. The Pennsylvania Northeast Regional Railroad Authority owns the trackage in the Water Gap area. Delaware-Lackawanna Railroad operates the lines that run through the gap. Pennsylvania Route 611 occupies the right-of-way of a former trolley line. Martz Trailways has a bus station within the municipal boundaries of Delaware Water Gap. There are also numerous jitneys that stop there on their route between

authorized the building of a dam across the Delaware River at Tocks Island, upstream of the water gap. Meant to control hurricane-related flooding, it was never built. The land for the proposed reservoir, which had already been purchased, was used to create the Delaware Water Gap National Recreation Area in 1965. There are two visitor centers, one in New Jersey near the Delaware River bridge and the other in Dingman's Ferry, Pennsylvania. Headquarters is located on River Road in Pennsylvania. The New Jersey side of the gap is also protected within Worthington State Forest, a forest wholly contained within the recreation area.


Hiking trails


Mount Tammany Trail

One of two trails leading up 1,200 vertical feet to the summit of Mt. Tammany. Once completed, one can see views of Mt. Minsi in Pennsylvania on the other side of the gap.


Pahaquarry Trail

The second trail to the top of Mt. Tammany. The most challenging hike in the park is to combine the Red Dot and Blue Blaze trails into a loop. Park Services suggest ascending the Red Dot and descending the Blue Blaze, and the Blue trail is less steep.


Dunnfield Creek Trail

Dunnfield Creek Trail departs from the Appalachian Trail above the Delaware River, follows the creek for two-thirds of its length with numerous stream crossings. The trail then climbs a ravine to rejoin the Appalachian Trail at Sunfish Pond.

Rock climbing

The gap is a popular place to rock-climb in New Jersey. The climbs are . Most climbing is done on the New Jersey side due to easier access. There are about one hundred climbs on the New Jersey side. Climbs range from 5.1 to 5.14 on the Yosemite Decimal System scale. Climbers follow the gray dot trail along Route 80, then pass the large rock face, then go up the path to the route they choose. Beginning in 2010, the Pennsylvania side has been periodically closed to climbing during the nesting season for the

operated Weygadt Scout Reservation at the base of Mount Tammany from 1931 until 1968. The Reservation was originally home to two Scout camps—the Easton Council's Camp Weygadt on the southern part of the reservation and the Minsi Trails Council's Camp Minsi on the northern section of the reservation. In the later part of the 1930s, the Bethlehem Council moved their camp to the Poconos, and the entire reservation in the Water Gap became Camp Weygadt. Camp Minsi is now located in Pocono Summit, Pennsylvania, on the shores of Stillwater Lake. Pahaquarra Boy Scout Camp was located on the New Jersey side of the Delaware Water Gap on Old Mine Road at the abandoned Pahaquarry Copper Mine. The camp served Boy Scouts from the George Washington Council. Just north of this camp was Camp Cowaw Boy Scout Camp which served Raritan Council Boy Scouts.
