The greatest part with this place is the view on the french Alps with the Famous MT-Blanc. On the other side you can see the Jura mountains and right in between is Geneva with it's lac Léman right by the DropZone.
Denis, and Titou are just great, has well has the whole rest of the team. Titou,for those who know him, (he was my instructor when i started,i'm proud about it) left the center though this year to make his own in Challon.
The landing area is very small, and restricted compared to other skydive centers.
With only one plane, the time in between two jumps can sometimes be long, especially in full summer season.
There are no campgrounds nearby the center, but if you ask you should be able to find some reasonable cheap hotel.
Supermarkets and cafeteria are right close by if you want to eat.
Even though there are a few cons, the place is definitly worth it and a must if you are going through France.
Hope this answered you out a bit.
Have fun!
