Family visit: Broc, Gruyères, Montreux

We are having guests this week - my sister and cousin have come to us from Szczecin. They will be here only for a couple of action-packed days. The very first one -a must on a map of the nearby attractions - Broc, Gruyères, Montreux tour. Radek did the exact same tour with our friends (see this post), now it's my turn with family.
We started with a Cailler chocolate factory in Broc followed by Gruyeres cheese house and the village of the same name. Our last destination was Montreux- always beautiful, but truly spectacular by the sunset.
