Not allowed to be visited

In a breath-taking setting facing Mont-Blanc, Combloux lake has been the first ecological lake opened to bathing in France. The lake is filled with water sourced from the local drinking water network and is naturally heated by the sun rays.

More than 10,000 plants and a gently running cascade ensure the highest quality of water to the 1500 m² of swimming area. A special flooring helps saving the natural heat of the sun to keep the water's temperature between 19 and 26°C. With a maximum depth of 1.80m and an access via a gentle slope into the water, Combloux ecological lake is the ideal place to spend time with your family. The lake itself is surrounded by a grass area, next to a restaurant and benefits from a stunning view of the Mont-Blanc massif.

To ensure the highest quality of water, the access has to be limited to 500 entries per day. Please note that no reservation can be made, but you can purchase your ticket using one of the following methods:
- The day before via our website (www.combloux.com)
- Between 9:00 am and 10:00 am at the Tourist Office
- Directly at the lake from 11:00 am.

Tickets purchased in advance will not be refunded or exchanged.

At the entrance, you will be given a bracelet which allows you to enter and exit as many time as you like during the day.
