The Hölloch is a 200.4 kilometres long cave in the Muotathal municipality in Switzerland. It is also notable for having a depth of 938.6 metres and being the second longest cave in Europe. The initial exploration started in 1875 and was led by Alois Ulrich.
A large part of the exploration of this cave was led by one of the pioneers of speleology, Alfred B?gli. The explored length of the cave increased from 25 kilometers in 1952 to 100 kilometres in 1968 (it was the first cave in the world where the explored length reached 100 km). Until 1970, it was thought to be the largest cave complex in the world, this title now held by Mammoth Cave.
Don't try this one without a guide - you will easily get lost! The 192 km of caves place the Hölloch in 4th position on the international cave ratings list - something which would surprise mountain farmer Alois Ulrich, who found the first entry hole and began the first explorations in the middle of the Muotatal karst rock formations, way back in 1875. Today, professional guides take visitors from the Hölloch centre in Muotatal above Schwyz into the cool underworld - only 6° warm - with its fantastic rock formations, fossilizations and caverns.
You can count on a little more sunshine during a trip into the B?dmeren natural forest, further down the Silberen Tw?renen karst area. Also a record-holder, its 600 hectares are home to western Europe's largest spruce forest.
