The Arbeitsgemeinschaft Hoellochforschung AGH association is exploring the Karst area of the Muotha Valley with its caves in Central Switzerland.

We do not organize tours to the caves, please contact the Tourist Office in Muotathal or check the Links to other organisations (Trekking Team AG - Hoelloch Caves).

We would like to show you the world of Caving and the interesting history of the Hoelloch-Exploration.

Some links to related web sites are offered here.
