Participated in the 10h long Expedition Innominata. Honestly, while tiring, it was an amazing experience - lots of crawling, climbing, sliding and exploring different corners of Hölloch cave system. The guides were extremely knowledgeable and helpful. Good fitness is required, but it will surely be an experience to remember!

It's a great experience, definitely worth a tour, Petra is an excellent guide, told us lots of interesting stories. Apero in the cave is also a unique experience worth to try.

You look for a adventure look no further. Marcel is a experienced guide with great knowledge about the the development and history of the cave. The tour was amazing. We will come back for more :)

We made a Short tour with a friend. It was a fun experience and I would ago again once there is opportunity. My favourite part was when we turned off the headlamps and stood in an absolute darkness.😍

Inside view of a 200km long cave. Shortest tour (2 hours) can be easily accomplished.

An unforgettable experience for sure and a need to come back and explore more we couldn’t ask for something else.Our guide Michael was super helpful with everything and all of our guestions.The power of the cave is magnetising.A natural wonder that scream to be seen.Kids friendly too.We are definitely coming back.

We did a 2 day expedition with trekking.ch into the cave system of the Hölloch. We had a great time with our fantastic guide Marcel. Walk, creep and climb trough different areas of the cave, have a fondue in the evening and a great night in the 5 Star biwak:) Even it's quite pricey it's absolutely worth it!

I had a great time with the trekking team. They are pros. And this place is the highest in Europe. 220m!!! I jumped down with many other people. The scariest experience I had so far. You need a lot of bravery to jump down from the top of Verzasca dam. Or can I say Daammnn? :) Anyway it's a really good experience. Don't hesitate. JUST DO IT!!!
