This page lists 6 river swimming holes in New Jersey, where the swim season runs june through early september. Open each listing for directions, fees, and current conditions before you travel.
New Jersey has 6 documented river swimming holes in this directory — a river swimming hole is a deep bend, eddy, or slack-water pool in moving water — the pocket beside the current rather than the current itself. The New Jersey swim season runs June through early September, peaking July to August. Access points cluster near New Hope (pa), Lambertville (nj), Stockton (nj), Paterson, and Clifton. Every listing below links to a full page with directions, fee notes, access rules, and safety context.

Bulls Island Recreation Area on the Delaware River near Stockton, New Jersey (D&R Canal State Park) offers river swimming, trails, and camping. NJ State Parks day-use / parking fees typically apply — confirm dep.nj.gov before visiting.
View detailsPeople who know that the best natural experiences often come without a parking lot or a fee booth. You'll arrive to find a scene that feels genuinely wild for a place so close to the urban sprawl of northern New Jersey.
View detailsThe river moves with quiet authority here, its current neither lazy nor aggressive, but steady and purposeful, the way a great river should feel in summer.
View detailsDesignated a National Wild and Scenic River, this storied waterway carries with it centuries of history. From its deep roots in Lenape culture to its role in shaping the communities that grew along its banks.
View detailsThe centerpiece is a historic railroad trestle that arches over the river. Weathered iron and timber framing a sky that shifts from bright summer blue to the burnished gold of autumn.
View detailsDeep in the heart of the New Jersey Pinelands, the Mullica River threads quietly through Wharton State Forest like a secret the locals have kept for generations.
View detailsThe northwest highlands hold the river and gorge swimming — the Delaware Water Gap, Buttermilk Falls, the Musconetcong — and the Pine Barrens hold the cedar-water blue holes.
In this directory, Bulls Island State Park, Devils Hole, and Milford are among the river spots we document in New Jersey. The full list below reaches New Hope (pa), Lambertville (nj), Stockton (nj), Paterson, Clifton, Montclair, Cedar Grove, and Easton (pa).
Pine Barrens water is tannin-dark but exceptionally clean; the famous blue holes are cold, deep, and clear.
Check the nearest USGS gauge before you drive. Flow in cubic feet per second tells you more than any photograph: a stretch that is a calm green pool at 200 cfs can be an unswimmable chute at 900 cfs.
Give a river 24 to 48 hours after heavy rain. Runoff raises both the current and the bacteria count, and it pushes new strainers — submerged trees and branches — into places that were clear last weekend.
Read the surface. Smooth, glassy water moving fast is stronger than choppy water. A line of foam or debris shows you where the main current runs; swim on the inside of the bend, not the outside where the channel scours deep.
In New Jersey, the New Jersey Department of Environmental Protection publishes the water-quality and algal-bloom advisories that apply to these waters. Check them alongside the live gauge data rather than instead of it.
If the current takes you, do not try to stand up. Foot entrapment in moving water is a common drowning mechanism. Roll onto your back, point your feet downstream to fend off rocks, and ferry across the current at an angle rather than fighting it head-on.
Strainers are the river hazard people underestimate — a fallen tree lets water through and holds a body against it. Stay well upstream of any woody obstruction.
Avoid swimming below low-head dams entirely. The recirculating hydraulic at the base is uniform across the width and is very difficult to escape.
New Jersey blue holes are old sand-mining pits — very deep, very cold below the surface layer, with sudden drop-offs from the shallows. Several are posted no-swimming with active enforcement.
Cold water deserves more respect than most swimmers give it. The National Weather Service notes that cold shock can be as severe at 50-60°F as at 35°F, and that the involuntary gasp reflex can be triggered by water as warm as 77°F — which is why entering slowly matters even on a hot day.
New Jersey swims june through early september, with the most reliable water july to august. Pine Barrens ponds warm early; northern gorges stay cold.
Rivers peak in danger during runoff and peak in quality in late summer, when flow drops and pools clear and warm.
6 of these listings carry their own best-time note from the land manager or from reader reports — open them for the specifics rather than relying on the state-wide window alone.
What to bring: Sticky-soled water shoes, a dry bag, and a throw rope if your group swims regularly in current.
We document 6 river swimming holes in New Jersey. That is the number with enough verified detail — access, directions, and conditions — to publish, not the total number that exist. They cluster near New Hope (pa), Lambertville (nj), Stockton (nj), and Paterson.

Of the 6 listed here, 4 free, 2 varies. Fees are usually a state park or day-use charge rather than a swimming charge, and they change season to season — open the individual listing before you drive.
Three things: the live flow or level at the nearest USGS gauge, the current advisories from the New Jersey Department of Environmental Protection, and the forecast for anywhere upstream of you. New Jersey blue holes are old sand-mining pits — very deep, very cold below the surface layer, with sudden drop-offs from the shallows. Several are posted no-swimming with active enforcement.
Generally no, not straight away. Runoff raises the current, pushes new debris into familiar pools, and spikes bacteria counts. Give moving water 24 to 48 hours to clear after heavy rain.
