Hölloch – Biggest cave system in Europe

With 210 kilometres of explored length, the Hölloch is not only the largest cave system in Switzerland and Europe, but one of the largest caves in the world. Since speleogists discovered a new spectacular link in August 2020, there are now 1033 metres of altitude between the lowest (551 m) and the highest (1584 m) point of this world-famous cave system – a new world record! 

This big cave system offers unforgettable cave experiences for outdoor lovers, companies, schools and other groups. Adventurous or relaxing – let yourself get infected by the enthusiasm our expert cave guides bring across. Let yourself be enchanted by this fascinating hidden jewel of a cave. 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. Whether you choose to do a short tour or a longer expedition, we guarantee amazement!

GENERAL INFORMATION 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". The road to the parking lot at the restaurant Hölloch can also be reached with bigger coaches.

Arrival by public transport: by train to Schwyz and from there take the bus no. 501 to “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.
The following cancellation fees apply:
29-20 days prior to the tour: 20 % of the full price.
19-14 days prior to the tour: 50 % of the full price.
13-1   days prior to the tour: 80 % of the full price. Same day cancellations will be charged with 100 % of the full tour price.

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).

Short Tour 

This is not something you do every day. This was a unique experience for our team. Especially, turning off our lamps in the middle of the cave. 🙂 I will recommend this event to other departments for sure.

Short Tour with cave raclette and fire show

It was an unforgettably beautiful, exciting and interesting event! The atmosphere at the raclette dinner is a dream, the service was great. The Fire Devil was a complete success!
We would like to thank all contributors for the super effort. All 25 guests were thrilled. Also the barbecue we were allowed to use at the end of the party was very nice. Many thanks for EVERYTHING

Hölloch Parcours

 
Everything was top! I will certainly recommend the tour and possibly even book a longer tour. It was just great, thank you for this great experience!

Anna, September 2021

Hölloch Short Tour

Our guide was extremely competent, very entertaining, great. He fully met our requirements in every respect. His explanations were adapted to our level of knowledge. They were well understandable, interesting and peppered with genuine Muotathal humor. He succeeded in presenting his enormous knowledge about the formation of the cave, about geology, about the exploration of the cave, about the fauna in the cave in a way that fascinated all participants. It was a pure joy to listen to him and his inspiring way of leading spread to the whole group in no time. This could also be seen from the many questions asked by the participants. On behalf of my colleagues, but also on my own behalf, thank you very much for this unique tour.
