Hölloch Expedition Water Dome (Winter Expedition)

This all-day guided expedition will take you through the Hölloch cave system to the spectacular underground waterfall, Wasserdom.

At the Hölloch restaurant, you and your group will meet your certified cave guide. You’ll be equipped with everything you need for this expedition. Helmets, climbing gear, headlamps, and more will be provided.

During the 7-hour expedition to Wasserdom, you’ll follow the massive main passage to the Giant Hall. From there, you’ll climb to the old Dombiwak and take a well-deserved meal break. After that, you’ll visit Wasserdom and its 30-meter high underground waterfall. Here you’ll discover the “Nyphargus,” a small cave shrimp that has lived here for thousands of years. Then, you’ll gradually make your way back.

One of the largest caves in the world is hidden in the beautiful Muotathal in the canton of Schwyz: the Hölloch. Over 200 km of the cave system have been explored so far, and a large part of it can also be discovered by amateurs.

The Hölloch was formed by underground water. Over a million years, this cave system has been created. Explore this fantastic and mystical underground world with a guide and let yourself be enchanted by stalactites and rock formations. The route of the short tour is accessible via stairs and paths. You can't explore the atmosphere of the Hölloch in an easier way.

At the Hölloch Center, you can also visit an interactive exhibition to learn more about this fascinating cave world.
