The Trummelbach Falls are impressive. Sure, you have seen waterfalls before. The kind that tumbles down steep hills or over a cliff. But have you seen one that is underground and so powerful it makes you want to hold onto the railing?
The Trummelbach Falls are quite unique, so it is not surprising that they are also a World Heritage site. They are also in fact Europe’s largest underground waterfalls and feature a series of ten waterfalls that are fed directly from the impressive Bernese alps above.
The glacial meltwater from the Eiger, Mönch and Jungfrau provide a jaw-dropping 20,000 litres (5200 gallons) of water per second to these ear-pounding falls. They certainly won’t disappoint!
It does pay to be prepared before you head out to the falls, so here is all the important information you need.

Useful Information
The Trummelbach falls are actually 10 waterfalls at varying heights inside the mountain which can be accessed by a lift or stairs. They are wheelchair accessible, which is great news. The modern tunnel lift takes you to a mid-point in the mountains around waterfall number 7.
The stairs are only moderately steep, but you should be in reasonable shape if you want to see all these glacial waterfalls. The stairs also have handrails which is super handy and help with safety as you can imagine, it gets very wet inside the mountain. If you are traveling with children, keep an eye on them around the falls.
Given how slippery it can get I would recommend you wear shoes with good grip, something like a hiking or outdoor shoe is the best idea. Slippers or sandals are not the best in this situation.
Also, keep in mind you will encounter a lot of spray, so bring a waterproof jacket which you can put on if you find there is too much spray.

Best Time to Visit
Trummelbach Falls can be visited most months of the year except for winter. This is due to ice and snow that can form in the waterfalls.
So, the best time to visit the Trummelbach Falls is in summer when they are at full flow and things are at the driest inside the tunnels. The only challenge with this is that this is peak season. So, I would suggest May or June, or September and October are ideal.
Try to get to the falls early to avoid the crowds and the organized tours which tend to arrive a little later in the morning, but still early enough.
How long does it take to visit the Trummelbach Falls?
Most people spend around 1-2 hours inside the Trümmelbach falls, depending on how much time you spend at each waterfall and how slowly you take the stairs. You can also spend some time at the restaurant’s outdoor seating area and enjoy the sunshine after you exit the complex.
