Option 1 : We recommend an amazing day trip to Chamonix-Mont Blanc, the roof of Europe.
Depending on the weather, climb to the Aiguille du Midi (3800 m) by cable car, or “mer de glace” and exploration of the glacier by cogwheel train. In this case, a second night in Annecy or Geneva is recommended for a saturday departur.
Option 2 : Return to your country. Geneva International Airport is 30 minutes from Annecy by taxi, or you can join Lyon airport by bus, or Paris by fast train (TGV).
