Scenic Jetboat Ride on Lake Brienz: 50 Minutes You Didn't Plan For

You've probably already seen Lake Brienz. From the train between Interlaken and Meiringen, from the road, maybe from a café terrace. That colour stops people mid-sentence. Blue-green, almost too bright, even when the sky is overcast. Most visitors look at it, take a photo, keep moving.

Fair enough. But from the water, the lake is a different place entirely.

50 minutes on the jetboat, and you'll see cliffs that drop straight into the lake, the Giessbach Falls from close enough to feel the spray, and coves along the north shore that no path reaches. Your captain has done this run hundreds of times. He still knows exactly where to slow down, and where to push it.

Lake Brienz doesn't get as much attention as Lake Thun. It has less infrastructure, fewer boats, no big hotels along the shore. That's exactly why it looks the way it does.

Little motorboat traffic. The water stays clear down to 260 metres. The glacial meltwater feeding it keeps the temperature low enough to hold that blue-green colour through every season. Iseltwald, the small village on the north shore, has about 400 residents. It got a wave of international visitors after a Korean TV series filmed a key scene on the jetty there. If you've seen the show, you'll recognise the spot immediately from the water.

On the south side, the Giessbach Falls drop roughly 500 metres across 14 steps. The hotel beside them opened in 1874 and is still running. When the boat stops in front of both, nobody talks for a few seconds.

The meeting point is at the quay in Bönigen, about five minutes from Interlaken Ost station. Show up 5 to 10 minutes before departure. The captain runs a short briefing, and everyone wears a life jacket. Rain gear and a jacket are available at the base if you need them. On a warm day, you probably won't. But you will get wet. That's not a side effect, that's part of it.

The first few minutes are relaxed. The captain points out what you're passing: why the water holds this colour, what's behind the Iseltwald story, which cargo ships used to run this route. Then the throttle opens. Up to 60 km/h on open water, cliffs rising on both sides, wind loud enough that you stop trying to talk.

First stop: the Giessbach Falls. The boat holds position close enough for the mist to reach you, far enough that you can take in the hotel above. Then the captain turns back, and the return is where it gets fun. 360° spins, sharp direction changes, spray from every angle. He reads the group and adjusts, but most people end up grinning whether they expected to or not.

The seats at the back get the strongest forces and the most water. When the captain asks who wants to sit there, he means it.

Phones stay on shore. There are free lockers at the base. It sounds annoying at first, but on the water you notice the difference: you actually look at what's happening instead of holding a screen up.

You still leave with something. The crew takes a souvenir photo during the ride, free to download online. If you want the video, a professionally cut 60 to 90 second clip in vertical format, it's CHF 29 at the base. It captures the ride better than a shaky phone clip ever could.

Included: life jacket, rain gear (optional to wear), safety briefing, free souvenir photo, lockers at the base.

Bring: clothes that can handle water. In warm weather, a t-shirt and shorts are fine. When it's cooler, wear layers that dry fast. Leave anything loose in the lockers.

If you have time after the tour, Iseltwald is worth the walk. The path from Bönigen along the lakeshore takes about an hour, flat and signposted. You saw the village from the boat. Seeing it on foot afterwards puts it in perspective.

There's a restaurant in the village right on the water. The jetty from the Korean series charges a small entrance fee now, but the rest of the village is open. After being on the lake at speed, walking the shore feels like a different version of the same place.

Most people who visit Interlaken see this lake from a window. That's a fine memory. But 50 minutes on the water turns it into something else. You don't just look at the lake. You're in it.
