The best way to go to Annecy in summer is to use the free bus from Duingt. The Line 50A-50B line takes you every 30 minutes: you avoid traffic jams and paying carparks in the city centre.

Maps are available at the “Bonlieu” tourist office. Annecy is very family-friendly with its many squares designed for children. Our advice: take a picnic to eat on the grassy areas of the Jardins d’Europe or the Pâquier then enjoy a good homemade ice cream from one of the many ice cream parlours in town.
