This natural site has been made accessible for visitors to explore the caves, admire the 150ft waterfall or even have a go on the zip-line!


This natural site, which has been made accessible to visitors, is the only underground gallery in Haute-Savoie open to the public. Follow a guide through more than 800ft of galleries and tunnels. You can also admire the 150ft waterfall, whose source can be found in the tumultuous waters of the St Ruph river. Or why not have a go on the 500ft-long and 130ft-high zip-line! A friendly and dynamic team is on hand to show you the ropes! Enjoy a local speciality out on the patio or visit the windmill exhibition to discover more about the local history and traditions.
