Schwarzwasserbrücke — A Wild Canyon 30 Minutes From Bern
There's a moment on this hike where you stop and look up. You're standing at the bottom of a sandstone canyon, next to a river that sounds louder than it should, on a trail that feels like it belongs in a nature documentary. And somewhere high above you — maybe 170 meters up — a steel bridge from 1882 crosses the gorge, with a railway bridge right next to it.
Thirty minutes ago, you were at Bern's main station.
Schwarzwasserbrücke is one of the most underrated day hikes near Bern. Not an Alpine postcard — something rawer. A deep gorge carved by a river called "Black Water," sandstone walls rising almost vertically, gravel beaches, old bridges, and a protected landscape where the river still flows freely, the way it has for thousands of years.
Why It's Worth the Trip
The canyon
The Schwarzwasser river has cut deep into soft sandstone over millennia, creating a gorge that feels surprisingly wild for how close it is to the capital. Vertical rock walls, narrow forest trails along the water, cool shade even on hot summer days, and gravel banks where you can sit, swim, or have a Swiss-style riverside picnic (Brätli).
Above, the Bernese Plateau — farms, villages, fields. Below, a different world entirely. The contrast hits you the moment you start descending.
Three bridges, three centuries
This is the detail that makes Schwarzwasserbrücke special — and that most visitors don't fully appreciate until they see all three from the canyon floor.
The old stone bridge (1832) — at the bottom of the gorge, right next to the river. Before the high bridges existed, the road descended in steep switchbacks to the valley floor and crossed the water here. Originally wooden, rebuilt in stone in 1832. Today it's a hiking landmark — atmospheric, quiet, surrounded by forest and sandstone.
The steel road bridge (1882) — a high arched steel structure spanning the entire gorge from above. It replaced the old descent: instead of zigzagging down and back up, the road now crossed the canyon in a straight line, roughly 170 meters above the river. It's still in use today and is protected as a historical monument.
The railway bridge (1907/1979) — built right next to the road bridge for the Bern–Schwarzenburg railway line. The original 1907 steel bridge was replaced in 1979 with the current reinforced concrete structure. Today, the S6 S-Bahn stops at Schwarzwasserbrücke station — which means you can literally step off a train and be at the edge of a canyon.
Standing at the bottom, looking up at both high bridges while the river rushes past the old stone bridge at your feet — that's the moment where you feel the scale of this place and the story of how humans conquered this gorge over 200 years.
The confluence
Where the Schwarzwasser meets the Sense river, the landscape opens up. Wide gravel beaches, shallow water for wading, and space for picnics. The Sense is one of Switzerland's longest rivers with a completely natural, unregulated riverbed — rare in a country that engineers almost everything. In summer, this is one of the best swimming and picnic spots near Bern.
The Hikes
1. Short loop from Schwarzwasserbrücke (best for first-timers)
The simplest option. Start and finish at the same station. No planning needed.

Distance | 9 km |
Elevation | ±158 m |
Difficulty | T1 (easy) |
Highlights | Descent to the old bridge, river walk, Sense confluence, suspension bridge, return |
Good for: a relaxed walk with time to sit by the water. Not a sport hike — a nature pause.
2. Niederscherli → Schwarzwasserbrücke (best river walk)
A linear walk along the Sense river to the point where it meets the Schwarzwasser. The bridge towers ~70 meters above the valley at the end — a dramatic finish.

When to Go
Best season: May through October. Dry days are ideal.
Summer is the best time — the gorge provides shade on hot days, and you can swim at the confluence. The combination of hiking and river swimming makes this one of the best day trips from Bern in July and August.
Autumn is beautiful for the forest colors and soft light on the sandstone walls.
After rain: don't hike the lower trail. Water levels in the gorge can rise quickly, even in summer. Rocks become slippery, riverside paths get muddy, and what was a calm river an hour ago can become dangerous. Wait at least a day after heavy rain before going to the canyon floor.
Rules — This Is a Protected Area
The Sense–Schwarzwasser zone is a Naturschutzgebiet (nature reserve). These rules are enforced and matter:
Fire: only on gravel banks close to the water. Forbidden in forest, bushes, and wherever signs indicate. No large barbecues.
Dogs: on leash from May to July (nesting season). Keep them close to you at all times near water and forest.
No boats or inflatables on the Schwarzwasser — banned year-round by Canton Bern.
No climbing on the sandstone walls unless specifically marked as permitted. No rappelling, no ice climbing.
No cars off designated roads. Park only in marked areas.
General: stay on trails, take your trash, don't disturb wildlife, keep noise down. This is a nature reserve, not a festival ground.
Practical Information
Detail | Info |
|---|---|
Best starting point | Bahnhof Schwarzwasserbrücke |
Getting there | S-Bahn S6 from Bern HB → Schwarzwasserbrücke (~25 min, every 30 min) |
Region | Sense–Schwarzwasser nature reserve, Canton Bern |
Season | May – October |
What to bring | Water, snacks, trash bag, light jacket, towel (summer), grippy shoes |
Swimming | Yes, at the confluence (summer). No inflatables on the river |
Brätli/picnic | Yes, on gravel banks by the water. No fire in forest |
For your first visit, take the short loop from Schwarzwasserbrücke station — 2 hours, easy, no planning. Descend to the old bridge, walk along the river, reach the confluence, and come back. Don't rush it. The point isn't to complete the trail — it's to sit on the rocks, listen to the water, look up at the bridges 170 meters above you, and realize you're half an hour from the Swiss capital.
If you loved it — come back for Stage 1 of the Schluchtenweg (Schwarzwasserbrücke → Schwarzenburg). It's the most rewarding single-day hike near Bern that almost nobody talks about.
In summer, bring a towel. The swimming spots at the Sense confluence are genuinely good — clear water, gravel beaches, shade nearby. A hike with a swim in the middle is the best kind of day trip.
And check the weather before you go. The gorge is beautiful when it's dry. When it's wet, it's dangerous. Respect the river — it's called Black Water for a reason.
