Thonon Les Bains

Thonon-les-Bains sits beside Lake Geneva in the Haute-Savoie region of southeastern France. While not a coastal dive destination, the city serves as a gateway to nearby freshwater diving opportunities in Lac Léman (Lake Geneva) and surrounding quarries in the region. Local dive activity centers around training and access to nearby freshwater sites, with a few centers providing courses, equipment rental, and guided dives. Expect cool freshwater visibility, with species typical of large alpine lakes and occasional thermoclines. For divers, Thonon-les-Bains is primarily a base for freshwater diving excursions and accessing nearby dive sites rather than a traditional sea dive hub.
