- His situation :
- Halfway between Annecy and Geneva, Copponex is situated below the slopes of Saleve and Mount Zion and delimited downstream by Usses.

- The landscape is dominated by a semi grove (and sometimes open fields surrounded by hedges) due certainly to the clearing time of the Allobroges or the Middle Ages.
