  • cosy fondue evening and overnight at the comfortable cave bivouac
  • a winter favourite (available from November until March)


It’s an opportunity to unwind and get away from civilisation for a couple of days. Longer tours heighten the senses and make such tours a more intense experience. Longer tours also give us the opportunity to look deeper into the cave’s uniqueness. We’ll have time to talk about the earthworm “Octolasium transpadanum” or the “Niphargus” a little amphipod. Discover the miraculous “gallery 800” or “Arabian nights”, traverse the “Höllental” with its fantastic dripstones. You’re moving though a world of rock formations more than 120 million years old which were formed and shaped over the past million years!

The bivouac is our little island of comfort in this isolated subterranean world. Particular emphasis was placed to environmental issues when building the bivouac. However – there’s running water in the kitchen and there are toilets (even though special ones). There’s comfortable spots to sit and cosy places to sleep at with optimal insulation.

Nothing better or cosier than a chat over a lovely fondue. And often just before we go to sleep, when all is quiet and the lights are out we cannot help but to reflect on the fact of being thousands of meters inside a mountain in another world.

The next thing you know will most probably be the lovely smell of coffee on the next morning. A healthy breakfast later we’re on the way to discover more of this magical world of the Hölloch.

With more than 200 explored kilometers in length, the Hölloch is one of the world’s largest cave systems.

Discover how the water has carved its way relentlessly through nooks and crannies over close to a million years to finally create the cave we explore today on our various tours.

For people who fear that claustrophobia might be a problem we can reassure to some extend: There are a number of narrow spots, however, for people who fear comfortable travelling in a normal 4 person lift, there shouldn't be any anxiety issues. For the small percentage of people with stronger claustrophobia we refer to our guided short trips.

Fear of heights: You will be adequately secured in all those areas that are a little more exposed. Your guide will also be able to help and assist.  

The temperature is a constant 6 degrees Celsius and the humidity is close to 100 %. 

The Hölloch cave ist situated in 6436 Muotathal, in the area of Stalden.

Arrival by car: you can use the parking in front of the  restaurant Hölloch in Muotathal/Stalden. The coordinates for your navigation system are: "Stalden 15, 6436 Muotathal" or "Restaurant Hölloch, Muotathal".

Can I visit the Hölloch unguided?

No. The Hölloch is not generally open for public and you will need a specialised guide for a tour.

Are there any toilets at the Hölloch?

On longer or multi-day tours there are certain spots that are equipped with a toilet and of course at the Dom bivouac (with limited comfort of course).

Can one smoke in the Hölloch?

The air at this cave is wonderfully clean. In earlier days there were talks of offering cures for lung patients. It would be a shame to spoil the good and healthy breathing air. We do ask you to refrain from smoking (if possible). On longer tours with overnights at the bivouac some exceptions can be granted if not possible otherwise.

Can I bring my dog on a guided short tour?

No, you cannot bring your dog or pet. Also for the safety of your furred friend. 

Do I need climbing experience to go on a Hölloch tour?

No. All the spots that would involve climbing are equipped with ladders and ropes. So no climbing experience required, however a basic physical fitness is of advantage.

Can I cancel my booking for a Hölloch tour?

As soon as you've made a definite booking and we've confirmed it, the contract is binding and subject to the terms and conditions listed. Cancellations need to be made in written and by indicating the reasons for a cancellation.

Safety First

Our motto is very simple: "Safety First"!
Indeed we offer many adventurous programmes, but when it comes to your safety, we are no adventurers. We've worked this way for more than thirty years now and have no intention to change our ways on this subject. Trekking Team was the first outdoor company in Switzerland to receive the security certificate "Safety in adventures."

The company's senior management is actively involved in all programmes and takes full responsibility for all areas of security and checks the compliance with the company's security concept on a regular basis. We prioritise the training of our staff and put guides in charge who are trained and specialised for the specific areas and activites. Guides are trained and certified by the Swiss Outdoor Association (SOA) and for the cave part by the speleology school "Schweizerische Schule für Höhlenbefahrungen Hölloch" (SSH).

Hölloch Kurzführung

Unser Guide war äusserst kompetent, sehr unterhaltsam, grossartig. Er hat unsere Ansprüche in jeder Beziehung voll und ganz erfüllt. Seine Ausführungen waren unserem Wissensniveau angepasst. Sie waren gut verständlich, interessant und gespickt mit echtem Muotathaler Humor. Es ist ihm gelungen, sein enormes Wissen über die Entstehung der Höhle, über die Geologie, über die Erforschung der Höhle, über die Tierwelt in der Höhle in einer Art und Weise zu präsentieren, die alle Teilnehmenden fasziniert hat. Er wäre ein hervorragender Lehrer (als langjähriger Sekundarlehrer und Teacher Trainer kann ich das beurteilen). Es war eine reine Freude, ihm zuzuhören, und seine inspirierende Art der Führung hat sich in kürzester Zeit auf die ganze Gruppe übertragen. Das konnte man auch an den vielen Fragen der Teilnehmer feststellen. Im Auftrag meiner Kolleginnen und Kollegen, aber auch in meinem eigenen Namen, danken wir ganz herzlich für diese einmalige Führung..
