Biking around Valley Forge is the best way to visit. You have to take time to stop at various monuments and read everything. This trail has some very steep grades both up and down.
Beautiful Trail! Bridge out in Pennpack Park
I have cycled the D&R numerous times from Frenchtown to Washington Crossing and from Lawrence Township to New Brunswick. I have not ridden through Trenton because I have been told it isn't very safe for a lone rider who doesn't know exactly where the trail begins and ends. The trail along the Delaware is beautiful and very well kept. The trail is wide with crushed stone and easy to navigate on any kind of bike. The trail along the Raritan is nice until you get closer to New Brunswick. The trail is rockier with many potholes and not as well kept, plus there are a few spots where you need to dismount your bike and walk. I highly recommend the D&R for biking, hiking and running.
I have cycled the D&L from Washington Crossing to Uhlerstown a few times. The scenery is beautiful, but the trail itself is not well taken care of. Some parts are completely grown over or only allow one hiker/cyclist to pass at a time. There are also miles of large gravel that I think would be very difficult for road bikes, non-hybrid bikes of hikers with balance issues. It is also very crowded on the weekends.
Have a comfort bike with wider tires 24 speeds. There are in most parts of the trail 2 tracks. Mostly unkept so poor for biking. Trail is grass and like I said 2 bike tire tracks. However would be great for hiking.
During the past two decades, I have been on numerous urban trails that link parks, historical sites and cultural centers, helping to revitalize old neighborhoods and improving quality of life to residents of our cities.
This Frankford Creek Greenway, unfortunately, is not one of these trails. Most of the trail's route runs past salvage yards and other industries in a sketchy part of town. The site of the colonial-era Wheatsheaf Tavern, which was demolished in 2007, is now an overgrown, trash-strewn lot marked by a hand made sign and the only real green space is the strip of vegetation between Lewis St. and active Norfolk Southern/NJ Transit RR tracks. One positive feature of this section is that it provides opportunities for railfans to get good views of freight and commuter trains that frequently pass by.
Although most of the trail's asphalt surface is in good condition, the same cannot be said about the short concurrency with Richmond St. As of mid-2026, the markings directing cyclists to use the street and pedestrians onto the sidewalks have faded and are hard to make out as sections of both have crumbled away. Both the street and sidewalk are now very rough and badly in need of repairs.
In all fairness, the trail does provide a mostly offstreet link from Aramingo Ave. to the Port Richmond Trail and will eventually be extended northwest to the Tacony Creek Greenway. It is also part of both The Circuit and East Coast Greenway and will likely get more attention once all of these trails are joined together. In the meantime, it serves as little more than a connector to other, more scenic paths.
Very scenic good ride , if your biking I would recommend ride early otherwise you encounter many walkers , strollers etc which can be a hazard if you are biking and cone around a corner the a surprise.
Nice trail to get in 10 round trip , scenic , rest areas , food .
We really enjoyed riding on the D&L Trail once we were on the trail. We planned to stay in Bethlehem and pick up the trail there. However, we stayed on the south side of the river because by the map, it looked like hotels were closer to the trail from that side. It took us about 3 miles of riding before we could finally connect with the trail. The signage in Bethlehem was terrible. We then rode out to Rieglesville and had a beautiful ride. And then rode back to Bethlehem, and again trying to find how to get across the bridge from the trail was another 3 mile ride. We thought it would be easier coming from the trail but it wasn't. This should be a great marketing tool for the city and we fully expected better signage. We will definitely ride this trail again but won't be staying in Bethlehem.
My wife and I walked the trail after dinner tonight. It’s a fine 12 foot wide trail, very well maintained and great for moms running with strollers or teaching kids to ride a 2 wheeler. Too short for a serious adult bike ride and it’s not terribly scenic but it’s nonetheless a nice addition for the community. It does lack mileage markers which would be helpful.
26 flat miles between Jim Thorpe and White Haven. The section from White Haven south to Rockport is crushed stone and we did it on road bikes with 25mm tires no problems. Going north from Jim Thorpe, there were washouts filled with sand and wider tires would have been nice.
The trail goes downhill 1-2% as you head south.
