What the Trümmelbach Falls are
The Trümmelbach drains the glacier walls of the Eiger (3,970 m), Mönch (4,099 m) and Jungfrau (4,158 m). Its catchment area covers 24 square kilometres, up to half of it under snow and ice. The water has cut into the rock and plunges in ten stages through a narrow gorge – not down the outside of a cliff like the Staubbach Falls, but inside the mountain. Switzerland Tourism calls them the largest underground waterfalls in Europe.
During the melt, according to the operator, up to 20,000 litres per second roar through the cleft, plus, according to Lauterbrunnen Tourism, 20,000 tonnes of scree a year. The falls have been open to visitors since 1877. Today a tunnel lift takes you inside; from there you climb stairs past the individual falls. The falls are part of the Swiss Alps Jungfrau-Aletsch UNESCO World Heritage Site.
- Location
- About three kilometres beyond the village of Lauterbrunnen, on the valley road towards Stechelberg.
- At the entrance
- Large free car park, self-service restaurant with viewing terrace, small souvenir shop.
- Water
- Ten glacier waterfalls, up to 20,000 litres per second.
Trummelbach Falls tickets and opening hours 2026
Tickets are sold at the till at the entrance; the operator does not mention online sales. It explicitly offers no group rates. With the Lauterbrunnen guest card (issued by your accommodation) you get 10% off, according to Lauterbrunnen Tourism. Prices are in Swiss francs, not euros.
| Trümmelbach Falls | Detail |
|---|---|
| Adults | CHF 18 |
| Children and teenagers 6–15 | CHF 8 |
| Children under 4, dogs | no admission |
| With Lauterbrunnen guest card | 10% off |
| April – June, September – end of season | daily 09:00–17:00 |
| July and August | daily 08:30–18:00 |
| Season 2026 | early April to 9 November |
None of the sources says what children aged four and five pay – ask at the till. Opening in spring and closing in autumn depend on the weather; according to Jungfrau Region Tourism the site closes temporarily every spring because of extreme seasonal conditions.
Honestly: From December to March, according to the operator, the Trümmelbach carries hardly any water – and the falls are closed anyway. Even in April and October, after frosty nights, only a few dozen litres per second come down. If you want the roar, come between June and September, when the glaciers are melting. In April or early November, don't just turn up on the off chance – check first that it is open.
How to get to Trummelbach Falls from Lauterbrunnen
By train you first go to Lauterbrunnen: 22 minutes from Interlaken Ost, every 30 minutes, no change. At the station, bus 141 towards Stechelberg leaves for the Trümmelbachfälle stop, seven minutes away; it too runs every 30 minutes (SBB timetable, travel date 5 October 2026).
| Route | Journey time | Frequency |
|---|---|---|
| Interlaken Ost – Lauterbrunnen (train) | 22 min | 30 min |
| Lauterbrunnen station – Trümmelbachfälle (bus 141) | 7 min | 30 min |
| Trümmelbachfälle – Stechelberg, Schilthornbahn (bus 141) | 5 min | 30 min |
By car, take the Wilderswil exit, head towards Lauterbrunnen and carry on for about three kilometres beyond the village. Parking at the entrance is free – cheaper than any car park in the valley.
On foot it is about three kilometres up the valley floor from Lauterbrunnen. Neither the operator nor the tourist office gives a walking time; for the way back, simply take the bus.
Rule of thumb: If you are in Lauterbrunnen anyway, the detour costs you the admission, a bus ride and a good hour and a half. It is worth it – during the snowmelt and in high summer.
How long does a visit take – and who can go in?
Lauterbrunnen Tourism and Jungfrau Region Tourism allow one hour, Switzerland Tourism one to two hours. With the trip from Lauterbrunnen and a coffee on the terrace, that is half a morning.
- Children
- Babies and children under four are not allowed in, for safety reasons. From six they pay CHF 8.
- Dogs
- Not allowed in, also for safety reasons. Plan for someone to wait outside with the dog.
- Accessibility
- Switzerland Tourism rates the site as “partially accessible”. Besides the lift there are stairs; ask the operator beforehand what exactly can be reached with a wheelchair or pushchair.
- Clothing
- Sturdy shoes. The paths can be wet and slippery.
Trummelbach Falls in the rain: is it worth it?
Yes. The falls are inside the mountain, and the paths there are wet anyway. After rain, according to the operator, the Trümmelbach also carries more water. If you don't want to go up to the Jungfraujoch on a rainy day because the top is in cloud, this is a real alternative for CHF 18.
Honestly: Rain does not spoil the falls, but it does spoil the rest of the day: you won't get the view from Wengen or Mürren. And on wet stairs it matters even more – sturdy shoes, not sandals.
Combining Trümmelbach Falls with Lauterbrunnen, Mürren and the Schilthorn
The falls lie right between the village of Lauterbrunnen and the Schilthorn cable car valley station in Stechelberg. The day almost plans itself: in the morning to the Staubbach Falls in the village, at midday into the mountain, in the afternoon on by bus to Stechelberg (five minutes) and by cable car via Gimmelwald to Mürren or all the way up the Schilthorn.
| Schilthorn cable car from Stechelberg | Adults | with Half Fare Card |
|---|---|---|
| Stechelberg – Mürren, return | CHF 23.60 | CHF 11.80 |
| Stechelberg – Schilthorn, return | CHF 115.00 | CHF 57.50 |
Note for autumn: from 19 to 30 October 2026 the Stechelberg – Gimmelwald – Mürren cable car is closed for maintenance; a replacement bus with limited seats runs instead. If you would rather go to the other side of the valley, take the cog railway from Lauterbrunnen to Wengen and Kleine Scheidegg.
“After the falls I want to carry on up the Schilthorn – with the ticket already in my pocket.”Cable Car Roundtrip to Schilthorn
Honestly: The operator charges CHF 115 for the same route, CHF 57.50 with the Swiss Half Fare Card – Tiqets knows neither the Half Fare Card nor the Swiss Travel Pass. According to the provider, the Tiqets ticket cannot be cancelled. For the Trümmelbach Falls themselves you don't need to book anything in advance: guided tours from Interlaken cost over €200 for what you can do on your own with a train, a bus and CHF 18 admission.
