You’re driving up Route 29, the river is on your left, and if you blink, you might miss the turn for Raven Rock. Most people just keep going toward Frenchtown or New Hope. They shouldn't. Tucked right between the Delaware River and the Raritan Canal, Bull’s Island Recreation Area is this weird, beautiful, and slightly rugged slice of New Jersey that feels more like the Pacific Northwest than the Garden State.
It’s tiny. Honestly, it’s basically just a 79-acre spit of land, but it punches way above its weight class.
Whether you’re a serious hiker or just someone who wants to eat a sandwich near some water without being harassed by a swarm of flies, this place matters. It’s the kind of spot where you can see a bald eagle and then immediately see a guy struggling to untangle a fishing line from a sycamore tree. It’s real. It’s unpolished.
The Suspension Bridge Everyone Is Afraid Of (And Why You Should Cross It)
If you visit Bull’s Island Recreation Area and don’t walk across the footbridge to Pennsylvania, did you even go? This bridge is the centerpiece. It’s a suspension bridge that connects New Jersey to Lumberville, PA.
It swings.
Not in a "the world is ending" kind of way, but enough to make you grab the railing if a jogger passes you. It was built by the Roebling family—the same folks who did the Brooklyn Bridge—so it’s got that heavy-duty 19th-century engineering vibe. When you stand in the middle, you’re looking down at the wing dams and the ripples of the Delaware. You’ve got the Black Eddy on one side and the calm canal on the other.
Once you get to the Pennsylvania side, you’re in Lumberville. Most people walk straight to the Black Bass Hotel or the Lumberville General Store. It’s a great way to pretend you’re a rugged outdoorsman for twenty minutes before sitting down for a $15 latte.
The Ghost of the Campground
If you look at old reviews or talk to someone who grew up in Hunterdon County, they’ll tell you about camping at Bull’s Island. You can't do that anymore. Well, not on the northern section.

After some massive floods—specifically the 2004, 2005, and 2006 trio that absolutely wrecked the Delaware Valley—and a tragic accident involving a falling tree limb in 2011, the northern half of the island was permanently closed to camping. The New Jersey Department of Environmental Protection (NJDEP) basically let it go back to nature.
It’s eerie.
You can still see the remnants of old paved paths being reclaimed by the woods. It’s a "rewilding" project that wasn't exactly planned, but it worked. This area is now a massive sanctuary for migratory birds. If you’re into birding, this is your Super Bowl. We’re talking Cerulean Warblers, Yellow-throated Vireos, and American Redstarts. They love the sycamores. These trees are massive—some of the biggest in the state—and their white, peeling bark makes the whole forest look like a skeleton in the winter.
Boating, Fishing, and Getting Muddy
Look, the boat launch at Bull’s Island Recreation Area is one of the most reliable spots to get a kayak or a motorized boat into the Delaware. But here’s the thing: the river is moody.
One week it’s a lazy stream where you can practically walk across the rocks; the next, it’s a brown, churning monster that will eat your oars. Always check the USGS gauge at Stockton before you head out.
Fishing here is legit. You’ve got:
- Smallmouth bass (the kings of the river)
- Striped bass (when they’re running)
- Walleye (if you’re lucky and know where the deep holes are)
- Channel catfish (mostly near the canal inlets)
The D&R Canal side is different. It’s stagnant, quiet, and full of turtles. It’s where you go if you want to paddle without worrying about a current taking you halfway to Trenton.

The D&R Canal Trail: 70 Miles of "Why Are My Legs Sore?"
The island serves as a major trailhead for the Delaware and Raritan Canal State Park. This trail is a beast. It’s flat, crushed stone, and it runs for nearly 70 miles.
From Bull’s Island, you can bike south toward Stockton and Lambertville. It’s about 6 miles to Stockton (go to the Stockton Market for food) and another 4 to Lambertville. It’s a straight shot. No hills. Just you, the canal on one side, and the river on the other.
The coolest part about this section of the trail? The lock houses. You’ll see these small, historic stone buildings where the lock tenders used to live back in the 1800s when the canal was a major highway for coal. It’s a weird feeling to realize that the quiet path you’re biking on used to be a loud, filthy, industrial corridor.
Things People Actually Get Wrong
Common misconception: You can swim here.
Nope. Don’t do it. The NJDEP is pretty strict about this. The Delaware River has nasty undercurrents, and the "beaches" are mostly silt and sharp rocks. If you want to swim, go to a pool. If you jump off the bridge, you’re probably going to get arrested or, worse, hit a submerged rock.
Another mistake is thinking the island is "just a park." It’s actually a fragile ecosystem. Because it sits in the middle of the river, it gets hit with everything—invasive species, flood debris, and heavy foot traffic.
Why the Sycamores Are Dying (And Staying)
You’ll notice some of the giant trees look a bit rough. Between the Emerald Ash Borer killing the ash trees and various fungi hitting the Sycamores, the canopy is changing. But the park rangers and environmental groups like the Delaware Riverkeeper Network argue that leaving these "snags" (dead standing trees) is better for the owls and woodpeckers. It’s messy, but it’s healthy.
Parking Is a Nightmare (The Truth)
Let's be real. If it’s a Saturday in July and the temperature is 85 degrees, you aren't finding a parking spot at 11:00 AM.

The lot fills up fast. People bring their entire extended families, three grills, and a gazebo. If you want peace, go on a Tuesday morning. Or go in November. Bull’s Island in the late fall is incredibly underrated. The mist coming off the river at dawn makes the whole place look like a scene from a movie.
What You Need To Pack
Don't be that person who shows up in flip-flops and realizes they have to walk two miles to find a bathroom.
- Bug Spray: The mosquitoes near the canal don't play. They are the size of small drones.
- Water: There are fountains, but they are sometimes turned off in the shoulder seasons.
- Binoculars: Even if you aren't a "bird person," seeing an Osprey dive for a fish is cool.
- Cash: If you walk across to Pennsylvania, some of the smaller spots prefer it, though most take cards now.
How to Actually Spend Your Day There
Start at the main parking lot and head straight for the bridge. Get your photos. Cross over and walk the trail on the PA side for a bit—it's called the Delaware Canal State Park (confusingly similar name, I know).
Come back across and head north into the "Natural Area." This is the closed-off campground area. It’s quiet. Follow the loop through the overgrown sycamores. You’ll eventually hit the point of the island where the river and canal split. Sit there for a minute.
Then, head back and hop on the D&R Canal trail heading south. Walk for about a mile, then turn around. By then, you’ve seen the best of the river, the history of the canal, and the weird "forgotten" vibe of the northern island.
Real Insights for Your Visit
- The Flood Marks: Look at the side of the buildings or the bridge supports. Sometimes you can see markers indicating where the water reached in 2005. It’s terrifyingly high. It puts the power of the river in perspective.
- The "Raven Rock" Name: The area is technically Raven Rock. The "island" was created by the canal construction, which cut it off from the mainland.
- Winter Value: The park stays open year-round. Cross-country skiing on the canal path after a fresh snow is arguably better than biking it in the summer.
Actionable Next Steps
If you’re planning a trip to Bull’s Island Recreation Area this weekend, do these three things:
- Check the River Stage: Visit the National Weather Service river forecast for the Delaware River at Stockton. If it’s above 12 feet, the trails might be muddy or partially submerged.
- Download the Merlin Bird ID App: Since this is a premier birding spot, the app will help you identify the weird calls you’re going to hear in the canopy.
- Arrive Early: Aim for 8:30 AM. You’ll get the best light for photos on the bridge and you won't have to fight for a parking spot near the boat launch.
