This Hölloch cave tour is an adventurous and exciting short expedition following the foot steps of the first explorers. It starts in the developed part of the cave, then you walk along splendid side paths where the first Hölloch pioneers explored over more than hundred years the “Widmer”- and “Saxergang” with nail shoes and candle laterns. We move on to places where we cannot walk upright anymore, areas where we have to crawl or climb up and down ladders and slip through narrow passages. This makes this tour somewhat expedition-like. But don’t worry, it’s not that tight and the requirements (rather sporty / rather leisurely) can well be adapted to the needs/abilities of the group.

You’ll hear about the formation of this huge cave system and the creatures that live within, there are stalactites and sinter formations to admire. Your guide will have you turn off your lights and experience complete darkness and stillness. There’s a myriad of fascinating things to discover on this tour. Join in!

To round off your tour, groups have the possibility to book a cave aperitif or  a cave raclette with us. Nothing better than having a chat over glass of wine surrounded by candles and music.

Or if you’d rather have a BBQ before or after your tour, there is a BBQ spot next to the Hölloch. There is no additonal charge for the use of the BBQ area but you’d need to book ahead.

Meeting point: Hölloch Wärterhaus in 6436 Muotathal Stalden.

Requirements: This tour is well manageable with a normal fitness/condition; comparable to a mountain tour with easy crawling and climbing passages. Climbing sections are partly secured with chains and ladders. During the tour there are two narrow shafts (Otterkamin and Teufelswand) Also suitable for children from about 9 years.

To bring: Warm wool socks; long thermo underwear (shirt and trousers) and/or a thin turtle neck pullover and a pair of leggings/joggings*. Over that: old, warm, durable clothes that are robust enough to endure wear & tear. Additional reserve clothes for the journey back home because cave clothes can get very dirty. (Alternative: rental of cave overall for CHF 25.00 per person). If available, bring your knee pads.

*Please note – the temperature in the cave is constantly at 6°C, the air humidity at almost 100%. As long as you move you normally feel warm enough. Generally it’s recommended for people who are sensitive to cold to wear for example the combination thermo underwear AND thin turtle neck pullover under the cave overall/under your own clothes.


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).

Is smoking possible 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 simply "safety first"! We offer numerous - also adventurous - programmes, but we are not adventurers. This has been the case for the last 35 years of our outdoor activities and will remain so in the future. Trekking Team was the first outdoor company with the "Safety in adventures" certification.

We have set high standards for the quality of our programmes, the training of our guides and especially for safety aspects. The top management - all active guides and instructors - is directly responsible for these central areas. The cave guides are trained at the Swiss School of Caving Hölloch (SSH).

The company's safety policy is based on the following principles and procedures:

  • The safety of guests and employees is a top priority. It has priority over economic considerations. To prevent accidents during adventure and outdoor activities, everything must be done that is necessary according to experience, feasible according to the state of the art and appropriate to the given conditions.
  • Safe procedures for all adventure and outdoor activities are ensured through the application of an operational safety concept. With the help of this concept, any inadequacies are systematically identified and improved, thus keeping the safety level constantly high.
  • Accident prevention and protection of the health of guests and employees are essential to maintain and strengthen competitiveness.
  • We undertake to comply with all generally recognised national and international standards concerning the practice of adventure and outdoor activities as well as the relevant directives of the competent authorities.
  • We recognise the safety policy and the protection goals of the "safety in adventures" foundation as the basis for safety planning.
  • The processes and activities of our adventure and outdoor activities and the infrastructure and support work operated for them are continuously analysed (process analysis).
  • For all processes and activities of our activities and at all implementation locations, the relevant influencing factors and critical control points (CCP) are clarified with regard to safety (risk analysis).
  • For all identified critical control points, measures (e.g. controls, fixed procedures to be followed, reserved decisions, etc.) are defined that are suitable for eliminating hazards that exist at this point and minimising risks that arise at this point due to critical influencing factors.

Despite competent and safe implementation of the activities, accidents cannot be completely ruled out. The organiser cannot accept any liability for this; participation is at the participant's own risk. Participants must have sufficient health and accident insurance themselves. For Hölloch expeditions we also recommend membership of a recognised Swiss rescue organisation (e.g. REGA) or the conclusion of special rescue insurance.

Expedition Glitzertor

Our guide was a great treasure!
We had a lot of fun with him, as he himself is a wonderful person who takes and solves possible difficulties with humour. The pace was just right for all of us participants. He even had a good time with our son: it was a unique day in our lives without grumbling 🙂

Expedition Innominata

A Hölloch tour is always a super experience. Hans is a very experienced guide with a lot of background knowledge. We felt very well looked after with him. Despite the circumstances that the planned Innominata tour could not be carried out due to the water level (which we were informed of in advance), we were offered an interesting and challenging alternative tour. Everything was perfectly organised and we had a lot of fun!

We loved our cave short expedition!! Fabian was such a great guide, and made sure he repeated everything in English for us. We felt well taken care of. You could sense his love for being there as well. Thanks

Expedition Glitzertor

Good morning dear trekking team!

I am not a fan of questionnaires, so I prefer to answer with personal words. We drove back to Munich yesterday after our 9h tour, it was a long day that we will certainly not forget for the rest of our lives. Everything was super organised and ready for us in advance. The best decision was to rent the overalls, what would we have done "without" them!

A thousand thanks to Urs and Tobias, who accompanied and guided us safely in every situation and made this day an unforgettable one, a mama-sons experience in a class of its own! Thank you for letting us do this with you! We had incredible fun, certainly reached our limits a bit in terms of fitness, the sporting challenges such as the ladders, rope sections and sliding on the seat of our trousers were a lot of fun without stressing us out. This tour was the highlight of 2021.

Thanks to all of you! We will be back, for sure, maybe for one of the shorter tours. I've already got a few ideas from the guides!

We wish you a wonderful 4th Advent, a Merry Christmas and all the best for 2022. Stay healthy and we look forward to seeing you again!

Best wishes from Upper Bavaria to Switzerland!

Your family K. December 2021

2-Day Expedition

Martin adapted the programme to our needs and wishes without us even having to express them. He knows the corridors inside out and can tell us a lot of interesting things about the cave and everything else. Although he is about 40 years older than us, he seemed to have taken the whole tour more easily than we did, impressive!

Short Tour

The feedback from my work colleagues was all very good! The enthusiasm of the tour was very great. Many thanks for the great insight into the enormous cave system.

Hölloch Parcours

A top guide, Chrigu was the ideal companion on our adventure. He was able to tell us a lot of interesting facts about the cave and took us to many great places. If we come back, then definitely Chrigu again :-).

Everything worked out great.
