The origin of the place name is unclear: it could derive from the Latin word "aquatica" or from the dialect word "gias" (resting place for the flocks). A Winter sports resort in the Valley of Evançon located in a valley at the foot of Monte Rosa, Ayas is composed of approx. 35 settlements, including some really famous ones such as: Antagnod, Saint Jacques, Crest, Frachey and Champoluc. In the recent decades, the tourism has developed considerably and radically changing the look of the valley, which is now known not only for the great natural wealth but also for the vast skiing area. The modern and functional Monterosa Ski plant links the Val d'Ayas to Valle Gressoney through Col Bettaforca. The whole area offers excellent tourism facilities and infrastructures. Ayas proposes itself as the best location for a holiday in all Seasons: besides skiing and skating, the area offers great possibilities for skydiving and paragliding.
The area was part of the Kingdom of the Burgundians and in 515 it was donated to the monks of the Abbey of Saint Maurice d'Agaune and belonged to the fief of Graines. Later when the populations of Saint Jacques from Switzerland immigrated into the area, they gave the area the name, still current, of Canton des Allemands: In the XIII century it became the feud of Challant, the most illustrious noble family from Val d'Aosta.
