Thonon-les-Bains is a sophisticated lakeside city located on the southern shores of Lake Geneva, serving as the sub-prefecture of the Haute-Savoie department. As the historic heart of the Chablais region, the city has a rich Savoyard identity that is evident in its grand architecture and cultural traditions. Thonon is uniquely built on two levels: the historic upper town perched on a cliff and the pretty fishing port of Rives below, connected by a 19th-century funicular. The city gained prominence as a premier hydrotherapy destination, with its thermal baths attracting elite visitors since the Belle Époque. The Château de Ripaille, set amidst vast vineyards, remains the city's most prestigious landmark, reflecting its past as a ducal residence and a religious retreat. Today, Thonon-les-Bains is a thriving community that benefits from its proximity to Geneva, integrated into the Léman Express rail network. It features a high quality of life with numerous nautical activities, mountain excursions, and a bustling local market that showcases the finest alpine produce, making it a gateway to both the lake and the high mountains.
