Location & Getting There

Delaware and Raritan Canal State Park is located New Jersey. The park’s coordinates are 40.500565, -75.0531541.

Things to Do

New Jersey state parks defy the state’s industrial reputation, protecting vast tracts of wilderness including the unique Pine Barrens, Appalachian ridgetops, and wide Atlantic beaches. Visitors can hike sections of the Appalachian Trail, kayak through the tea-colored waters of the Pinelands, swim at ocean or glacial lake beaches, fish in well-stocked streams, and camp in deep forest. The state also preserves crucial moments in American history, offering tours of key Revolutionary War sites, battlefields, and historic villages.

Best Time to Visit

Fall (September–October) is arguably the best time, offering cool hiking weather, beautiful hardwood foliage in the northern parks, and fewer bugs in the Pine Barrens. Summer (June–August) is peak season for coastal parks and lake swimming, but inland parks can be hot, humid, and buggy. Spring brings excellent birding during the coastal migration and good conditions for trout fishing. Winter is quiet, perfect for solitary hikes and, occasionally, cross-country skiing when snow falls.

Visitor Tips

Entrance fees are typically charged from Memorial Day through Labor Day ($5-$10 per vehicle for residents, $10-$20 for non-residents). A State Park Pass ($50 for residents) covers parking for the season. In the heavily forested Pine Barrens (like Wharton State Forest), ticks are extremely common from early spring through late fall; use strong insect repellent and perform thorough tick checks. Coastal parks like Island Beach State Park often fill to capacity by mid-morning on summer weekends, so arrive very early.
