The Delaware River is a major river in the Mid-Atlantic region of the United States and is the longest free-flowing (undammed) river in the Eastern United States. From the meeting of its branches in Hancock, New York, the river flows for 282 miles (454 km) along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay.

The New Jersey Pine Barrens, also known as the Pinelands or simply the Pines, is the largest remaining example of the Atlantic coastal pine barrens ecosystem, stretching across more than seven counties of New Jersey. Two other large, contiguous examples of this ecosystem remain in the northeastern United States: the Long Island Central Pine Barrens and the Massachusetts Coastal Pine Barrens. The name pine barrens refers to the area's sandy, acidic, nutrient-poor soil. Although European settlers could not cultivate their familiar crops there, the unique ecology of the Pine Barrens supports a diverse spectrum of plant life, including orchids and carnivorous plants. The area is also notable for its populations of rare pygmy pitch pines and other plant species that depend on the frequent fires of the Pine Barrens to reproduce. The sand that composes much of the area's soil is referred to by the locals as sugar sand.

South Jersey comprises the southern portion of the U.S. state of New Jersey located between Pennsylvania and the lower Delaware River in the west and the Atlantic Ocean in the east. The designation of South Jersey with a distinct toponym is a colloquialism rather than an administrative definition and reflects geographical and perceived cultural and other differences between South Jersey and the northern part of the state. South Jersey is part of the Philadelphia metropolitan area, the seventh-largest metropolitan region in the nation with 6.288 million residents in the core metropolitan statistical area and 7.366 million residents in the combined statistical area as of 2020. South Jersey is known for containing the unique ecoregion known as the Pine Barrens, which remains largely undisturbed despite its location within the Northeastern megalopolis. The South Jersey Pine Barrens are the largest remaining example of the Atlantic coastal pine barrens ecosystem.

A 1950s proposal to construct a dam near Tocks Island across the Delaware River was met with considerable controversy and protest. Tocks Island is located in the Delaware River a short distance north from the Delaware Water Gap. In order to control damaging flooding and provide clean water to supply New York City and Philadelphia, the U.S. Army Corps of Engineers proposed building a dam. When completed, the Tocks Island Dam would have created a 37-mile (60-km) long lake between Pennsylvania and New Jersey, with depths of up to 140 feet. This lake and the land surrounding were to be organized as the Tocks Island National Recreation Area. Although the dam was never built, 72,000 acres (291 km²) of land were acquired by condemnation and eminent domain. This incited environmental protesters and embittered local residents displaced by the project's preparations when their property was condemned. After the Tocks Island Dam project was withdrawn, the lands acquired were transferred to the oversight of the National Park Service which reorganized them to establish the Delaware Water Gap National Recreation Area.

At the area's southern end lays the Delaware Water Gap, a dramatic mountain pass where the river cuts between Blue Mountain and Kittatinny Mountain.
