Cailler has been making chocolate since 1825 and its factory tours take visitors on an extravagant twirl through its history, including, naturellement, a chance to taste and visit to the factory shop. Best up are Cailler's chocolate workshops - themed, one- to 2-1/2 hours long, some designed for children. Workshops cost Sfr20 to Sfr75 including factory tour, and must be reserved in advance via email or telephone. Find the Cailler factory in Broc, 2km north of Gruyères; follow signs for Nestlé.
