In the early sixties Jean Vuarnet was asked by his hometown of Morzine to help develop the skiing-area around the town. He did that by creating the purposebuild resort of Avoriaz together with a group of young architects. Around Avoriaz he developed a new area for alpine skiing later linked to other areas in France and Switzerland known as The Portes du Soleil. Jean Vuarnet's has given name to the exclusive Vuarnet sunglasses which meanwhile belong to the alain mikli group.
In 1958, he married Edith Bonlieu, three-time French women's ski champion. His wife Édith and his youngest son Patrick were among the members of the Order of the Solar Temple cult who committed suicide in 1994.
