Expanded: 6 great one-day bike rides on central New Jersey trails

So you’re looking for a new place to ride your bike but don’t want to deal with traffic? Or you’re encouraging someone to bike who gets nervous around traffic? You need some kid-friendly options?

Central New Jersey has some great choice, and more trails are coming (it’s just not a fast process, unfortunately). I think these five six are fabulous; I hope you’ll love them too. I’ve listed them in no particular order and updated them for 2025.

Of course there are more trails than just these, so keep exploring and add your favorite to the comments section.

D&R Canal towpath

This is the big one — at 34 miles just on the main canal from New Brunswick to Princeton to Trenton, you can make a ride as long or as short as you like. I keep discovering ways to use it to help go somewhere else; think of it as Route 1 for bikes but far more relaxing.

It can get busy around Princeton, so give yourself some space and explore other sections. If you’re starting at Turning Basin Park in Princeton (big parking lot), try heading south instead of north, for example. Or park instead at the southern end of Princeton where the trail crosses Quaker Road.

Honestly, there are so many places to park and ride that you have no excuse to explore the entire length. (If you’re car-free, your train stations are New Brunswick, Princeton and Trenton. Princeton Junction too if you’re more comfortable with traffic.)

As you bike, look for turtles sunning themselves on logs. You might spot a blue heron too. Can you find this historical marker?

The route isn’t paved so you might encounter some mud after it rains. But much is crushed stone dust I’ll ride it with a road bike and 28 mm tires.

If you’re curious about canals, just know that this one is wider and deeper than the Erie Canal. By connecting the Delaware and Raritan rivers, it sped up the transportation of gods between New York and Philadelphia in the 19th century and was far safer than venturing into the Atlantic Ocean.

If you want to make a weekend of it in Princeton, I’ve got you covered.

And if you want to do loops between New Jersey and Pennsylvania, that’s further down the list.

Lawrence Hopewell Trail

This one is my favorite: a wonderful 20-mile loop that’s getting close to finished. The gorgeous 0.4-mile new boardwalk, curve and all, has opened in Maidenhead Meadows Park on the Lawrence Township side, eliminating the need to bike on busy Princeton Pike. Now the detour caused by construction of the Pike Town neighborhood is no more too. You still need to bike on some road sections, though, should you want to tackle the full loop, as I did. Here’s a Ride With GPS route of the full loop.

But it’s easy to do out-and-backs that are all trail (some paved, some crushed stone). Park in downtown Lawrenceville or at Mercer Meadows Park and you can ride for miles. The kid-friendly reward is ice cream and/or the bakery in downtown Lawrenceville. OK, not just for kids.

I actually biked to two of New Jersey’s best bakeries using the LHT and some quiet roads in Pennington.

Bonus: The LHT connect to the D&R Canal towpath near Brearley House. Normally you can ride traffic-free between there and downtown Lawrenceville, but the route through the Lawrenceville School is currently closed because of campus construction. Once that’s done, a bigger kid-friendly challenge is to bike from Turning Basin Park in Princeton to ice cream.

I’ve used the combination of the D&R and the LHT for bike rides to “weird” beer (here’s one) as well as to the more established River Horse Brewing. Just know you’ll need to deal with roads (mostly, but not entirely, low-traffic or with shoulders).

Loops across the Delaware River using the D&R and D&L trails

There are trails along both sides of the Delaware River from Frenchtown south to Trenton. Use the bridges, and you can turn a ride into a two-state loop of as little as 7 miles. Since that photo was taken, the bike path on the new Scudders Falls bridge has opened so there’s one more way to cross state lines.

You may catch a polo match if you’re doing a loop at the northern end!

Take that 34-mile option to New Brunswick noted on the bottom right of that sign with a grain of salt: this section doesn’t directly connect with the main Delaware and Raritan Canal towpath. You’ll need to bike into Trenton for that.

But the 10 miles south to Bristol on the Delaware & Lehigh Trail are lovely, more so now that the small but annoying gap in Morrisville has been closed. Unfortunately, cyclists and pedestrians not allowed to use the Burlington-Bristol Bridge to get to New Jersey. There seems to be a walkway, but it is locked.

Curious about Morrisville to New Hope on the Pennsylvania side, across to Lambertville and down to Trenton? I’ve done it.

Middlesex Greenway

It’s 3.5 miles out, 3.5 miles back, with a challenging bridge over the highway to get your heart rate up. When the kids complain, tell them they’ll love going downhill!

Start in Metuchen (parking at Greenway Park on Middlesex Avenue, or the Metuchen train station is a few blocks away); there’s only one way you can go — east.

You can stop around midway, just before going over U.S. 1, at the Tano Mall (Lotte Market, the anchor, is an Asian supermarket) or reward the kids afterwards with a slice of pizza or something else from one of the many eateries on and around Metuchen’s Main Street.

I love using this trail as part of my epic global food ride from Newark to New Brunswick (mostly) following the East Coast Greenway route. Portugal, India and more … all without leaving New Jersey.

Delaware River Heritage Trail: Crystal Lake Park to Roebling

This fantastic new section of the Delaware River Heritage Trail finally opened after some who-know-why last-minute delays involving crossing the River Line train track.

Park at Crystal Lake and follow the trail on its U-shaped route through the park, along a stretch on quiet road (or jump on the sidewalk) and back to trail that goes under U.S. 130. After the railroad crossing, you’re at the Delaware River and the site of an Roebling factory.

All told, this jewel of a trail is about 5 1/2 miles long.

If you’re comfortable with a few miles on the road, start your ride in Bordentown near the River Line station. Take Farnsworth Avenue, then turn right onto Bordentown Road until it runs into U.S. 130. Cross at the light, follow the trail that goes off to the right and you’ll land in Crystal Lake Park.

Bonus: From Bordentown, you can head north on an orphan section of the D&R Canal for several miles until it ends at Canal Road, which in turn leads to Lamberton Road by the Delaware River. For the more ambitious, you can bike on quiet roads and trails all the way to the baseball stadium. I’ve ridden it in the other direction. And here’s my experience biking just between Riverside and Roebling.

Columbia Trail

We can argue about whether this is in central Jersey, but we can agree that this 15-mile trail gets lots of love from riders. It’s an old railroad line, so nothing too steep. It’s unpaved, and I’ve found that the Hunterdon County side is better maintained that the Morris County end.

But what really stands out for me is something off the trail: an observatory run by the New Jersey Astronomical Association in Voorhees State Park jus a few miles away.  How a bunch of amateur astronomers built a big telescope in the 1960s, down to grinding the glass for the mirror, is a fascinating story and one I included in my trail report.
