Châtel cultivates a tradition of hospitality since 1860 with sulphurous and ferruginous thermal spring and health tourism, recognized for their therapeutic virtues. In 1862 a "Hotel des Bains" intended to receive curists is built. Other family hotels are built, and compete with imagination to welcome guests coming to "restore their health". Fashion is for wellness and enjoyment of free time. Then, Châtel becomes a  climatic spa resort, referenced since 1880 in touristic guides for its pure and balsamic air, the benefits of its waters, its rejuvenation treatment with milk and Chablais grapes, healthy food, but also for hunting and its wonderful landscapes.
In the 1920s, a new era with the practice of the mountain and the advent of skiing gives a new impetus to the village. Then after the Second World War, the creation of the Super-Châtel altitude site and the equipment of the Morclan slopes are inaugurated with great fanfare by the Director General of Tourism. Thus, the installation of the first cross-border ski lifts in Europe, gives Châtel the status of great winter sport resort.

It is then sponsored by the new radio station "Europe N°1" created in 1955 and which took up its winter quarters in Châtel (its national broadcast frequency on the territory will correspond to 1625, the altitude of Super-Châtel). Many stars and show-biz personalities flock every years, contributing to the notoriety of the resort.
The following decades are promising and constructive...

Their children Jean-Marc and Nathalie, join them after their learn at hotel school of Thonon-les-Bains and many times in other fine House. An extension of the kitchen and the restaurant was carried in 1986, the design of a wellness and balneotherapy area in 1989. The swimming pool was built for the summer of 1991, then covered for the winter of 1993 and extended with terraces the next summer.

In 1998, to complete the offer, Jean-Marc and Nathalie are partner to create Le Bois Prin. The old family alpine chalet, perched high up in the mountain, has been renovated and becomes a cosy altitude restaurant on the slopes of Plaine-Dranse and the ski link with Avoriaz in the heart of Portes-du-Soleil.
 
In 2000, to celebrate the millennium and the beginning of the new century, the pool was decorated with allegorical frescoes glorifying water, source of life and well-being, fountain of youth and health, reminding that it was the initial thermal and climatic vocation of Châtel.

In 2021, major work to raise and expand the BOIS PRIN is being undertaken, enhancing the high-altitude chalet restaurant and bringing a real touch of emotion and comfort to visitors.
