The good weather is coming from the west, so I headed west. I took the train and bus to Broc fabrique gare. From here I headed to Gorges de la Jogne. The hike through the canyon was beautiful. The tour around the Lac de Montsalvens was ok. Most of the time you were just too far away from the lake, and didn't had a nice view to the lake.
Maison Cailler had a nice introduction to the history of chocolate, and of course the history of Cailler. Bring sone headphone with you, it's more comfortable than having the device on your ear to listen to the stories.
