A dark tunnel hidden in the woods that most people walk right past daily. I almost missed the entrance because it is covered in leaves and quiet shadows.
My phone flashlight barely cut through the cold darkness waiting inside those old stone walls. The railroad tracks are gone but the tunnel still whispers about trains from long ago.
Water dripped from the ceiling and landed on my jacket with tiny cold splashes. I walked slowly because slipping on wet rocks inside a dark tunnel seems dumb honestly.
The far end opened up to a view that made my whole hike worth everything. A train used to blast through this mountain and now only curious explorers come here.
I stood in the middle and yelled just to hear the echo bounce around me. This hidden piece of history feels like finding a secret that nobody else knows about.
The Forgotten Railroad That Built This Tunnel
Not many people know the name Duluth, Winnipeg and Pacific Railway, but its legacy is literally carved into the hillside. This railroad line, commonly called the DWP, was built in the early 1900s to move iron ore and timber through the rugged terrain west of Duluth.
The tunnel near Ely’s Peak was a key piece of that operation.
Engineers blasted through solid rock to create the passage, which allowed trains to navigate the steep and unforgiving landscape. It was serious work, done by serious people, in conditions that were far from easy.
The tunnel stands as a quiet monument to that era of industrial ambition.
At some point, the line was abandoned as rail traffic patterns shifted and the economic need faded. The tunnel stayed behind, slowly becoming part of the forest.
Today, hikers walk through it and feel that strange mix of curiosity and awe. History has a way of hiding in plain sight, and this tunnel is proof of that.
Finding the Trailhead Without Getting Lost
Getting to the DWP Railroad Tunnel is half the adventure. The most common starting point is the small parking lot off Beck’s Road, just south of Duluth near the I-35 corridor.
It is easy to miss, and the signage does not exactly shout about the tunnel waiting up the trail.
Look for the Ely’s Peak trailhead markers. The lot is small, so arriving early on weekends is smart.
A map board is posted there, though it does not always highlight the tunnel as a destination, which adds to the mystery.
Another option is parking at the Grand Avenue chalet and biking or running the DWP trail, which adds about four miles each way. That route follows the old railroad grade, making it mostly flat and easy to follow.
Blue trail markers help keep you on track when the path gets a little confusing. Either way, once you find the start, the journey feels immediately worth the effort.

The Hike Itself Is Short But Rewarding
The walk from the Ely’s Peak parking area to the tunnel is roughly one mile. It is not a brutal hike by any measure.
The trail gains some elevation, but the grade is gentle enough that most people handle it comfortably, including kids and older hikers.
The path follows the old railroad bed for much of the route, which keeps things relatively smooth underfoot. That flat, wide stretch feels almost meditative.
You can hear birds, feel the breeze off the ridge, and really settle into the walk.
Side trails branch off toward rockier terrain and the peak itself. Those options add challenge if you want it.
The forest around the trail is thick and beautiful, full of birch, pine, and maple that shift dramatically with the seasons. Fall turns this hike into something almost cinematic.
Spring brings mud but also wildflowers pushing up along the edges of the path. Every season offers a completely different version of the same mile.
Stepping Inside the Tunnel for the First Time
Walking into the DWP Railroad Tunnel for the first time is genuinely memorable. The air changes immediately.
It drops in temperature, even on a hot summer day, and the sound shifts to something hollow and echoey. The stone walls close in just enough to feel dramatic without being claustrophobic.
Light filters in from both ends of the tunnel. You can always see the exit, which gives the passage a glowing, almost cinematic quality.
The rough-cut rock overhead has a raw, unfinished texture that reminds you this was blasted out by hand and dynamite, not machines.
Colorful graffiti covers much of the lower walls, which some people love and others find jarring. It adds a layer of modern character to the historic bones of the place.
Kids tend to sprint through it, laughing at their own echoes. Adults slow down and look up.
The tunnel is only a few hundred feet long, but the experience lingers much longer than the walk through it takes.
Rock Climbing Anchors Hidden in the Stone
One of the most surprising things about this spot is the rock climbing. The cliff faces near the tunnel and along the trail to Ely’s Peak are studded with old carabiners and anchors left by climbers over the years.
It gives the whole area an adventurous, layered energy.
A local rock climbing club has been known to set up here during summer. Beginners can sometimes join after signing a waiver and making the hike up.
The rock faces are varied enough to challenge different skill levels. Watching climbers work their way up the stone while you stand on the trail below is its own kind of entertainment.
Even if climbing is not your thing, the geological character of the cliffs is fascinating. The exposed rock shows the ancient structure of the hillside in a way that feels raw and real.
You can run your hand along the stone and feel millions of years compressed into a single surface. It is the kind of detail that makes a hike feel like more than just exercise.
The Views From Ely’s Peak Are Worth Every Step
Reaching the top of Ely’s Peak feels like a reward the trail quietly earns for you. The summit is rocky and open, with wide views stretching across the St. Louis River valley.
On clear days, Lake Superior shimmers in the distance like a silver mirror tilted toward the sky.
The peak sits at a modest elevation, but the surrounding terrain is low and open enough that the views punch well above expectations. Standing up there, wind in your face, forest spread below you in every direction, it is genuinely hard not to feel something.
The trail to the peak from the tunnel area is a bit more rugged than the flat railroad grade. Roots and loose rock make you pay attention to your footing.
Wear shoes with grip. The effort is short but real.
Most people spend time up top just sitting and taking it in. Some forget to take photos entirely, too absorbed in the actual view to think about documenting it.
That is a good sign.
What the DWP Trail Feels Like on Two Wheels
The DWP trail is not just a hiking route. Cyclists use it regularly, and the old railroad grade makes for a smooth, mostly flat ride that feels effortless on a good day.
The four-mile stretch from the Grand Avenue chalet out to the tunnel is a favorite for local riders.
The trail surface varies between packed gravel and dirt. It handles well in dry conditions.
After rain, some sections get soft and muddy, so timing matters. Biking in allows you to cover more ground and still have energy left to explore the tunnel and surrounding cliffs on foot.
The rhythm of pedaling through dense northern forest, with birch trees lining both sides and the occasional rocky outcrop breaking the treeline, is quietly wonderful. There is no car traffic to worry about.
No noise beyond wind and birdsong. It feels like the city of Duluth has completely disappeared, even though you are only a few miles from I-35.
That contrast is part of what makes this trail so easy to love.
Seasonal Changes That Transform the Trail
Every season at the DWP Railroad Tunnel tells a different story. Summer brings lush green canopy and that refreshing cold air pouring out of the tunnel like a natural air conditioner.
It is a genuine relief after working up a sweat on the trail.
Fall is spectacular here. The maples and birches turn the hillside into a riot of orange, red, and gold.
The light filters differently through bare branches. The whole place takes on a quieter, more contemplative mood.
It might be the best time to visit.
Winter closes the tunnel access sometimes, and the trail becomes icy in sections. Traction devices for your boots are smart to bring.
Spring thaws create muddy stretches along the railroad grade, but the smell of the forest waking up is hard to beat. Wildflowers start pushing through the leaf litter by May.
Each visit feels genuinely different from the last, which is why locals come back again and again without feeling like they are repeating themselves.
Why This Place Stays Off the Radar
Part of what makes the DWP Railroad Tunnel special is how quietly it keeps its own secret. The signage at the parking area does not mention the tunnel at all.
First-time visitors often have to ask someone coming off the trail just to confirm they are headed in the right direction.
That lack of promotion is both frustrating and charming. It keeps the crowds manageable.
On most weekday visits, you might share the trail with just a handful of other people. The tunnel never feels like a tourist attraction because it has never been packaged as one.
Local hikers have passed the knowledge of this place along through word of mouth, social media posts, and occasional trail conversations. It has built a loyal following without any formal marketing behind it.
That grassroots reputation feels honest and earned. The tunnel does not need a sign because the people who find it tend to tell someone else about it.
That quiet chain of discovery has kept it alive and beloved for years.
Tips for Making the Most of Your Visit
A few practical notes go a long way at this spot. Park in the Ely’s Peak lot off Beck’s Road, not the Munger Trail parking area.
The two are close together but lead to very different starting points. Getting the right lot saves you confusion and extra distance.
Bring a light jacket even in summer. The tunnel air is noticeably cold, and if you plan to spend time exploring the cliff faces or the peak, wind can pick up fast on the ridge.
Layers are always a good call in northern Minnesota.
Wear shoes with actual grip. The rocky trail sections and the loose stone near the peak are not forgiving to flat-soled sneakers.
Start the hike in the morning if you want the trail mostly to yourself. Weekends draw more people, especially in fall.
Bring water, a snack, and your curiosity. The whole experience from parking lot to tunnel to peak and back can be done comfortably in two to three hours.
It is a perfect half-day adventure.
