If you want one easy outdoor habit that pays off in every season, it is hard to beat the Delaware and Raritan Canal towpath. It runs flat and quiet along the old canal, it is shaded for long stretches, and it threads right through our part of New Jersey. You can walk a slow mile or bike for hours, and either way it costs nothing.
A lot of people who live near it have only ever used a short stretch close to home. That is fine, but it is also worth knowing what you are actually standing on.
A long ribbon of history
The D&R Canal State Park stretches about 70 miles, crossing five counties and dozens of towns. The towpath is the old path where mules once hauled canal boats, which is why it is so reliably flat and so pleasant to walk. The main towpath has a natural surface of finely crushed stone over hard-packed dirt, level enough that most people find it easy going, whether on foot or on a hybrid or mountain bike.
It connects historic towns that played real roles in the American Revolution, so a ride along it doubles as a slow tour through the region's past. You are not just out for exercise. You are tracing a route that mattered.
What you'll actually see
Part of the charm is how much wildlife shares the corridor. Along the canal you can spot turtles sunning on logs, frogs, beaver sign, and a serious roster of birds, including great blue herons, osprey, and bald eagles. Early mornings are best for the quiet and the animals, before the weekend crowd arrives.
If you do not have a bike, the bigger towns along the route can sort you out. Lambertville and Frenchtown both have rental options, which makes a spontaneous river ride genuinely doable. Pack water, wear something you can layer, and you are set.
Make it a loop
The towpath really shines when you string it together with a town. Ride or walk a stretch, then duck into Lambertville or one of the canal towns for lunch and a wander, then head back the way you came. The flat grade means the return trip is just as easy as the way out, which is not something you can say about most trails.
For the shops and cafes along the canal towns, that trail traffic is a quiet but steady gift. People come for the ride and stay for a meal, a coffee, a bit of browsing. It is a reminder that the best customers are often the ones who were just passing through and found a reason to stop. The towpath has been giving the towns along it exactly that, day after day, for longer than any of us has been around to notice.
