Located 15 kilometers northwest of Annecy, Choisy belongs to the natural area of "Les Usses".

It is situated at an altitude of 390 meters, between a brook to the west, known as "les petites Usses", and Mandallaz Mountain to the east.

The demographic changes are mainly due to the arrival of new inhabitants who work in the Annecy and Geneva areas.

About thirty artisans and tradesmen work in Choisy, the vast majority belonging to the construction sector.

Agriculture remains the dominant activity, with about thirty dairy farms in operation.
