Lake Annecy
Auvergne-Rhône-Alpes
Lake Annecy is a glacial lake located in the Haute-Savoie department of the Auvergne-Rhône-Alpes region in Southeastern France. It is the second largest glacial lake in France, renowned for its remarkable water clarity and scenic beauty framed by the surrounding Alps. The lake was formed at the end of the Würm glaciation between 17,000 and 15,000 BCE, with inflows from seven mountain streams and a powerful underwater spring. Its northern tip is bordered by the city of Annecy, often called the "Pearl of the French Alps," known for its canals and historic charm. The lake's waters drain through the Thiou river into the Fier and eventually the Rhône. Lake Annecy supports a rich diversity of recreational activities, including boating, swimming, and paragliding, making it a popular tourist destination. The lake's environment is carefully managed to preserve its natural beauty and water quality, contributing to its reputation as one of Europe's cleanest lakes. A 33-kilometer dedicated cycling path, the "voie verte du lac d'Annecy," runs along its western shore, offering visitors spectacular views and access to the surrounding nature. The lake's shores are dotted with charming villages and natural reserves, including the regional natural park of the Bauges massif on its western side, providing a blend of cultural heritage and outdoor adventure.

History
Lake Annecy was formed during the last glaciation period of the Würm, around 17,000 to 15,000 years ago, as glaciers retreated and melted.
The lake's name historically referred to the northern part, while the southern section was known as Lake Duingt in medieval times.
The city of Annecy, situated at the lake's northern tip, has been inhabited since Roman times and rose to prominence in the Middle Ages as the seat of the counts of Geneva and later the counts of Savoy.
Over centuries, Annecy developed a rich cultural and religious significance, notably during the Counter-Reformation when it became a Catholic stronghold.
The lake area transitioned into a major tourist destination in the late 20th century, with efforts to preserve its natural environment alongside growing recreational use.
