A natural gas pipeline runs quietly beneath this bike path, and it gave the whole route its name. Above it, an old iron ore railroad bed now carries bikes, strollers, and trail runners instead of freight.
The ride follows a trout river through a rocky gorge in northwest New Jersey. One stretch crosses a high bridge where the water rushes far below.
I like that the views show up without any steep climbing.
Then there’s the lunch math. Small towns sit along the way, so your sandwich stop can land right in the middle of the ride.
I can’t imagine a better excuse to pedal a few extra miles.
So how does a former mining line turn into one of the friendliest rides in the state? The answer starts at a tiny railroad town.
An Old Railroad Bed Built for Easy Pedaling
Columbia Trail runs about 15 miles through Hunterdon County and into Morris County, New Jersey. It links High Bridge to the Long Valley area along a former railroad corridor.
Railroads don’t like steep hills, and neither do most casual riders. That shared preference makes the grade here gentle and steady from end to end.
The surface is mostly packed crushed stone. Hybrid bikes and mountain bikes handle it well, while skinny road tires may feel a bit nervous.
You’ll share the path with walkers, joggers, and folks on horseback in some areas. The trail is wide enough for everyone, so a friendly bell ring goes a long way.
Hunterdon County Parks manages the Hunterdon section, and Morris County Parks handles the stretch beyond the county line. Two park systems, one continuous ride.
Distance is flexible too. Many riders pick a short out-and-back, while stronger legs tackle the full length and turn around for the return.
Either way, the trail feels approachable from the first pedal stroke. It’s the kind of route that welcomes beginners without boring experienced riders.
Iron Ore Roots Beneath Your Tires
Long before anyone packed a trail snack here, trains hauled iron ore along this valley. The Central Railroad of New Jersey built its High Bridge Branch in the 1870s to serve mines in the region.
Iron was big business in northwest New Jersey back then. The railroad gave those mines a direct line to the industrial world beyond the hills.
Passenger trains used the route too, stopping in small towns that grew up around the tracks. Some of those towns still show their railroad roots today.
Freight service eventually faded, and the rails came up. That could have been the end of the story.
Instead, a gas company laid a pipeline under the old corridor. The surface above it became a public trail, and the Columbia name stuck around from that pipeline connection.
Knowing this history changes the ride a little. Those gentle curves and cuts through rock were carved for heavy locomotives, not for weekend cyclists.
Every flat, smooth mile is a gift from engineers who worked over a century ago. Not bad for a former ore route.
Riverside Company Almost the Whole Way
Water makes good company on a bike ride. The South Branch of the Raritan River keeps showing up beside you for long stretches of the route.
Sometimes it’s a bright glimpse through the trees. Other times the river sits right next to the path, close enough to hear every ripple.
That steady soundtrack makes the miles go by faster. It also keeps the air feeling a little cooler on warm summer days.
The South Branch is known for trout fishing, especially near the gorge. Don’t be surprised if you spot anglers standing in the current with their lines out.
Fields, farms, and woods trade places along the banks too. The countryside feels peaceful in a way that’s easy to underestimate until you’re actually in it.
For birders, the river corridor is worth a slow pedal. Keep your eyes open along the water’s edge and in the treetops.
Riders who like scenery more than speed will feel right at home. This is a route built for noticing things.
Rolling North Toward Long Valley
North of Califon, the trail keeps going into Morris County. The scenery shifts toward more open countryside as you approach the Long Valley area.
This section tends to feel a bit more rural. Farms and woods take turns along the corridor, and the ride stays pleasantly steady.
Morris County Parks manages this part of Columbia Trail. The handoff between counties is smooth, so you won’t notice much change underfoot.
Long Valley sits in Washington Township and offers another chance for food or a rest. It’s a handy turnaround or finishing point for longer rides.
Some riders arrange a car shuttle between ends. That trick lets you enjoy the full length one way without doubling the distance.
Others ride the whole thing out and back for a hefty workout. Both approaches work, depending on your legs and your patience.
Either way, this northern stretch adds variety to the journey. It proves New Jersey can deliver wide open country, not just busy roads.
Friendly Ground for Families and First-Timers
Kids, grandparents, and new riders can all find their rhythm here. The gentle grade removes the dreaded uphill struggle that ends so many family rides early.
The wide path also helps nervous riders feel secure. There’s room to wobble a little without causing trouble.
Since cars aren’t part of the trail, parents can relax more than they might on a road. Road crossings do exist, so teach young riders to stop and look.
Short sections work great for little legs. Riding from Califon toward the gorge bridge makes a memorable goal without an exhausting distance.
Walkers and runners love the surface too. Strollers with sturdy wheels can handle the packed stone in many spots.
Leashed dogs often join their humans on trail outings. Bring bags and water for your four-legged friend.
The best part might be the built-in rewards. A bridge, a river, and a snack stop make excellent motivation for any reluctant young cyclist.
Seasons That Change the Scenery
Autumn on Columbia Trail can look like a painting. Leaves glow above the river, and the hillsides around the gorge fill with color.
Fall is a natural time for a ride paired with a small-town lunch. Cool air makes the miles feel easy, and a warm meal feels extra earned.
Spring brings fresh green leaves and a livelier river. Wildflowers and birds add to the show along the corridor.
Summer leans on shade. The tree canopy covers long stretches, which helps on warm afternoons in New Jersey.
Winter rides are possible on milder days. The bare trees open up wider views of the river and rocky valley walls.
Conditions change with weather, though. Mud, puddles, or fallen branches can appear after storms, so adjust your plans accordingly.
No single season wins outright. Each one gives the same route a different personality, which is a pretty great reason to come back.
Know Before You Roll
Good news first: Columbia Trail is free to use. No ticket booth stands between you and those river views.
The trail is generally open during daylight hours. Check with Hunterdon County Parks or Morris County Parks for current rules and any temporary closures.
Parking areas sit near several access points, including High Bridge and Califon. Spaces can fill on pleasant weekends, so earlier arrivals have an easier time.
Restroom options along the route are limited. Plan stops in town if facilities matter for your group.
Bring a helmet, water, and a basic repair kit. A flat tire miles from the car is much less fun without a spare tube.
Wider tires suit the crushed stone best. A hybrid or mountain bike will feel more comfortable than a racing setup.
Respect trail etiquette with a friendly greeting or bell when passing. Shared paths stay pleasant when everyone looks out for each other.
A Ride Worth Planning a Saturday Around
Some outings need a long list of reasons. Columbia Trail only needs three: easy riding, river scenery, and lunch waiting in a friendly little town.
The old railroad history adds depth to every mile. Knowing iron ore once rolled through here makes the quiet feel even more special.
Ken Lockwood Gorge delivers the wow moment. That bridge over rushing water gives New Jersey residents something genuinely impressive to show off.
The towns deliver the comfort. High Bridge, Califon, and Long Valley turn a workout into a relaxed day trip.
Beginners can ride a few miles and feel accomplished. Experienced cyclists can stretch it out and still enjoy every scenic turn.
I believe the best local adventures are the ones you can repeat often. This trail fits that idea perfectly, season after season.
So pump up the tires and pick your lunch stop. The river will be there, rushing along like it’s been waiting for you.
