You’re standing on a metal grate barely wider than a pizza box. Below your boots? Nothing but eighty-five meters of mountain air and a very rocky ravine. It’s the Charles Kuonen Suspension Bridge, and honestly, it’s the kind of place that makes your palms sweat just looking at a photo.
People call it the "Europabrücke," but most hikers just call it terrifying.
Located near the sleepy village of Randa in the Swiss Alps, this steel giant stretches a massive 494 meters across the Grabengufer ravine. For a few years, it held the crown as the longest pedestrian suspension bridge in the world. Even though other bridges have since nudged it out of the top spot for length, none of them quite match the raw, high-altitude drama of the Mattertal valley.

Why this bridge even exists
Switzerland didn't just build this for the "likes" on social media. It was a necessity. There used to be a shorter bridge here, but nature had other plans. In 2010, massive rockfalls absolutely wrecked the previous structure just weeks after it opened.
The hiking route it serves—the Europaweg—is basically the holy grail for trekkers moving between Grächen and Zermatt. When the old bridge failed, hikers had to detour deep into the valley and climb back up. It added hours of grueling work.
To fix this, the community got together. They needed something higher, longer, and tougher. A local psychologist and winery owner named Charles Kuonen stepped up as the primary sponsor, which is why his name is plastered on the entrance. Swissrope, a specialized engineering firm, managed to build the whole thing in just ten weeks.
Ten weeks.
Think about that next time your kitchen remodel takes six months. They used "assembly sleds" and helicopters to move eight tons of cable into a wilderness area with zero road access.
Hiking to the Charles Kuonen Suspension Bridge
You can't just drive up to this thing. Sorry. If you want the view, you've got to earn it.
Most people start in Randa. It’s a quick train ride from Zermatt. From the station, you’ll see yellow signs pointing toward the "Hängebrücke."

The climb is no joke. You’re looking at about 600 to 800 meters of elevation gain depending on which loop you take. It’s steep. Like, "why-did-I-skip-leg-day" steep. The trail zigzags through dense larch forests that smell incredible in the summer, but the grade is relentless.
Which way should you go?
There’s a bit of a debate about the "best" direction for the loop.
- The Anti-Clockwise Route: This is the "official" recommendation. You hike up through the shade of the forest toward the Höüschbiel side. It keeps you cool during the hardest part of the climb. Plus, the bridge reveal is more dramatic.
- The Clockwise Route: If your knees hate descending steep slopes, go this way. The climb up Lärchberg is much steeper, but it’s arguably easier on the joints to go up the vertical stuff and down the more gradual switchbacks.
Expect to spend about four hours total for the round trip. If you’re feeling ambitious, you can add a detour to the Europahütte (Europe Hut) for a slice of cake and a coffee. It sits just above the bridge and offers the best vantage point for photos of the structure stretching toward the Weisshorn.
Engineering and the "Wobble" Factor
Let’s talk about the fear.
The bridge is only 65 centimeters wide. If you meet someone coming the other way, someone is going to have to get cozy or lean into the mesh.
It’s built with a patented vibration-damping system. Basically, they’ve tuned the tension so it doesn't swing like a playground toy every time the wind blows. It feels remarkably stable, but it is a suspension bridge. It moves.
The floor is a see-through metal grate. It’s designed that way so snow doesn't pile up and weigh the bridge down, and so wind can pass through it. But for your brain, it just means you can see exactly how far you’ll fall if the steel gives way. (It won't, but try telling your lizard brain that.)
Real Talk: Can you do it with vertigo?
Honestly? Maybe not.
I’ve seen grown adults freeze mid-way and have to be coaxed across. If you have "true" vertigo—the kind where your balance actually fails—this is your nightmare. But if it’s just a general fear of heights, keep your eyes on the orange markers at the far end. Don't look at your feet.
The bridge is a massive shortcut. What used to be a four-hour detour through the valley floor is now a ten-minute walk across the sky.
Essential Survival Tips for the Trail
Don't be that person who shows up in flip-flops. I've seen it, and it’s a recipe for a twisted ankle.
- Check the weather. Do not be on this bridge during a thunderstorm. It is a 494-meter lightning rod made of steel. If the sky looks dark, stay in the valley.
- Bring water. There are no fountains on the trail. Once you leave Randa, you’re on your own until you reach the Europa Hut.
- The Season. The bridge is usually open from May to October. In the winter, they often close it because of avalanche risks and snow loads.
- Timing. Get there early. By 11:00 AM in August, the trail is a conga line of tourists. If you want that "lonely mountain" photo, be on the trail by 7:30 AM.
What it costs
The best things in Switzerland usually cost a fortune. A train to the Jungfraujoch? That'll be your firstborn child.
But the Charles Kuonen Suspension Bridge is free.
There’s no turnstile. No ticket booth. You just walk up and cross. It’s one of the few world-class experiences in the Valais region that doesn't require a credit card, though you’ll definitely pay for it in sweat.
The Gear List
- Sturdy Boots: The trail is full of roots and loose rocks. You need ankle support.
- Trekking Poles: Your knees will thank you on the 800-meter descent back to Randa.
- Sunscreen: Even in the forest, the Alpine sun at 2,000 meters is brutal.
Beyond the bridge
If you’re doing the full Europaweg, the bridge is just one highlight. The trail continues toward Zermatt, offering views of the Matterhorn that most tourists never see. You’ll pass through tunnels carved into the rock and over old rockslides where the mountain is still actively shifting.
It’s a reminder that the Alps are alive. The bridge isn't just a tourist trap; it’s a triumph over a landscape that is constantly trying to wipe away the paths we build.

Actionable Next Steps:
Check the current trail status via the Zermatt Tourism website before you head out, as rockfalls or maintenance can close sections of the Europaweg without much warning. Pack a windbreaker even on sunny days—the wind whipping through the Grabengufer ravine can be significantly colder than the temperature in Randa. If you’re traveling by train, use the SBB app to time your arrival at Randa station; the regional trains from Visp or Zermatt run like clockwork, usually every 20 or 30 minutes.
