Tourism office by Martinewezel
The office doesn't only provides brochures and information about the several "must do" activities, but also they organize (English)guided day excursions by touring bus to Switzerland and Italy. For instance to Aosta and the Lago Maggiore.
Also for a free map of the city, this is the place to go.
Location of the office: next to the church, at the "Place du Triangle de l'Amitié, 85"
