Posted by The Trümmelbach Falls are one of the most spectacular natural attractions in Switzerland and a true highlight of the Lauterbrunnen Valley in the Bernese Oberland.
This valley is famous worldwide for its waterfalls – no fewer than 70 cascade down the steep rock faces – with the best known being the Staubbach Falls and the Trümmelbach Falls.
What makes the Trümmelbach Falls unique is the fact that they flow inside the mountain. Unlike most waterfalls, the water is not visible from afar. Instead, visitors walk through tunnels, galleries and stairways carved directly into the rock, following the powerful glacier water as it rushes through the mountain.
What Are the Trümmelbach Falls?
The Trümmelbach Falls are a system of ten glacier waterfalls that drain the meltwater from some of the highest peaks in the Bernese Alps.
The water comes mainly from the glaciers of the Eiger, Mönch and Jungfrau mountains and plunges deep inside the mountain toward the valley floor.
At peak times, up to 20,000 liters of water per second thunder through the narrow rock channels. The sound, the spray and the vibrations make the visit a dramatic experience, especially in summer when the glaciers melt most intensely.
Walking Through the Waterfalls
One of the great advantages of the Trümmelbach Falls is that they are fully accessible to visitors. A system of tunnels, stairs, platforms and bridges allows you to walk safely through the mountain and observe the waterfalls from very close range.
An elevator takes visitors up part of the route, reducing the number of steps and making the visit manageable for most people in average physical condition. Nevertheless, there are still stairs and uneven surfaces, so sturdy shoes are highly recommended.
Opening Season and Best Time to Visit
The Trümmelbach Falls are only open during the warmer months. The typical visiting season runs from April to October, depending on weather conditions and snow melt.
During the winter months, from early November until the end of March, the waterfalls are closed for safety reasons.
Opening hours:
Usually from 9:00 am to 5:00 pm. In high summer, opening times are often extended from 8:30 am to 6:00 pm.
The best time of day to visit is either in the morning or later in the afternoon, when larger tour groups are less common.

How to Get to Trümmelbach Falls
Trümmelbach is located a few kilometers south of Lauterbrunnen, directly in the
Lauterbrunnen Valley.
Getting there is very easy, as there is only one road through the valley, running between steep mountain walls.
By car:
Drive through Lauterbrunnen toward Stechelberg. Shortly after leaving Lauterbrunnen, you will see signs for Trümmelbach. A large, free parking lot is located on the left side of the road.
By bus:
The local bus from Lauterbrunnen to Stechelberg (line 141) stops directly at Trümmelbach, making public transport a convenient option.
Facilities at Trümmelbach
Near the parking lot, you will find a large restaurant with outdoor seating, ideal for a break before or after your visit. On the short walk (about 200 meters) to the entrance, you pass a souvenir shop offering local products and postcards.
The ticket office is located directly at the entrance to the waterfalls. Toilets are available near the entrance area.
Is the Visit Worth It?
Yes – especially if you are already visiting the Bernese Oberland. The Trümmelbach Falls offer a very different experience compared to classic outdoor waterfalls. Being inside the mountain, surrounded by roaring water and smooth rock walls, makes this attraction unique in Europe.
Visitors who enjoy nature, geology and dramatic landscapes will find the entrance fee well justified. Those who prefer open views and easy walks may enjoy the free waterfalls of the Lauterbrunnen Valley more.
Combine Your Visit with Stechelberg and Mürren
If you are already in Trümmelbach, it is highly recommended to continue to the end of the valley at Stechelberg. From here, a cable car takes you up to
Mürren, a beautiful car-free mountain village with stunning views of the Alps.
This combination makes for a perfect day trip: waterfalls in the morning, mountain scenery in the afternoon.
