Broc village and Nestle Factory.
There are trains from Bulle to Broc and thn on to the Cailler/Nestle chocolate factory, from the last station a short walk takes you to the entrance for a tour of the factory.
A small charge for adults to take the tour, which is primarily one where you view videos of the whole production, there is little viewing of the actaul production of the chocolates. At one point there are several trays of chocolates from the Cailler line and one can sample as many as your digestion can accept.
A final video of the factory thru the ages and then a chance to purchase boxes of chocolates or chocolate bars.
Most mornings start of with some mist or fog or low lying clouds that eventually burn off in the morning. My tour was in the morning and as I left to walk up to Broc, I tool the 2 photos , one of the location of the factory amid the mountains, the other one shows a very misty bridge along the river Sarine, that is in places wide enough to be called a lake.
The photo 4 is a distant view of the castle and village of Gruyere, it is located west of broc and maybe about 5 kms away as the crow flies.
