Opis:
This tour leads us into the Grotte des Cavottes near Montrond le Chateau in the French Jura region. The cave is for the most time orientated in horizontal directions but also got some vertical shafts where different levels of the cave intersect. This leads to a total depth of 115m where the cave ends at a big underground lake. To reach that point you first have to pass a narrow and super exhausting meander.
