Holloch in Muotathal SZ
With a length of more than 200 kilometers, Holloch in Muotathal SZ is the eighth longest cave system in the world. The stalactite cave owes this to groundwater that has eroded the rocks for almost a million years.
The fairy tale cave is open to visitors but is still used for research purposes. For example, a new animal species, the brown and white fake scorpion, was discovered in Holloch in 2010. There are several guided tours and excursions that you must register in advance.
Lac Souterrain de Saint-Léonard VS
There is a 300 meter long lake between Sion VS and Sierre VS. However, this is not found in any ordinary landscape map as it is located underground. It hides under a vineyard in the middle of the Valais Alps. Lac Souterrain de Saint-Léonard is the largest underground lake in Europe.
The water cave is accessible by boat, allowing visitors to enjoy a unique view: everything is accompanied by a geological and historical lesson by the boatman and a light show on the cave wall. Prior online registration is required to visit the cave.
Cave mill Col-des-Roches NE
The marshy area at Le Locle NE is rich in water, but the area is not well suited for waterworks as it is only a small river. Or is it? More than 400 years ago, three millers decided to take advantage of the last section of the river. There the water flows in a waterfall into the natural limestone basin of the Col-des-Roches gorge. It was converted into a cave mill by the millers.
Even today it is the only cave factory in Europe. There is now a museum in the cave where visitors can learn about the unique cave work. If you want an individual tour or are planning a group trip, you should clarify this in advance by phone or email.
Kesslerloch SH
Kesslerloch is a 200 square meter cave in Herblingertal SH. At first glance, the cave is quite inconspicuous. However, if you have some prior knowledge, you can see the importance of the region in terms of traces of settlement from the Ice Age. Bones from 53 different animal species have been unearthed so far. Among other things, from extinct animals such as mammoths and woolly rhinos. The finds are now on display at the All Saints Museum in Schaffhausen. The forest area where the cave is located is freely navigable.
Caves of Mont Vully FR
The Lamberta Caves are located in Haut-Vully FR. The tunnels dug into the sandstone appear to have been made by giant animals. In fact, it dates from the First World War and was man-made in 1916. They were created for the defense of the Swiss Mittelland. The 200-meter-long tunnels were later occupied by the infantry.
Today the place is a popular playground for children to play hide and seek.
Caves of St. Beatus BE
According to legend, it was once St. A dragon lived in the Beatus Caves. But when Saint Beatus confronted him with a cross, the creature escaped and drowned in Lake Thun. According to the story, Beatus lived in the stalactite cave until his death.
Today, one kilometer of the 14 kilometers discovered in the cave is open to visitors. Thanks to the cave lighting and light arrangement, the cave system seems to hold something magical and fairy tale-like.
Grotte aux Fees VS
The Grotte aux Fées in Valais is freely accessible to the public. Although the walking part of the cave is only one kilometer long, the 50-meter-high waterfall is the main attraction. The cave owes its existence to him for digging the waterway in this way.
It is not hard to believe that fairies were once suspected here, due to the light flowing down the legendary fairy fountain along with the waterfall, and the magical curves in the rock.
Hell caves in Lorzentobel ZG
Höllgrotten in Lorzentobel, near Baar ZG, was discovered in the 19th century when an attempt was made to build a railway tunnel. The calcareous water that formed the cave was later discharged, preventing the development of the cave.
Not entirely smooth today, the cave offers a unique experience to watch the special rock formations.
