The Maison Cailler tour was absolutely fantastic - I'd highly recommend it for both children and adults.

The first stage is a trip through history - a series of themed rooms with moving props and excellent narration (it looked like there were almost a dozen languages available).

The second stage was a self-guided area where you can listen to stories from those involved in the production of Cailler chocolate. There were also stations around the room to see, smell, and touch the different ingredients used.

Next you could see an example assembly line in action, with thorough descriptions, and you were given chocolates fresh from that line at the end of the hall. You could watch the factory workers active in a larger room following that, though they were only working on one type of chocolate when we were there.

Following that, there was a hallway that gave step by step instructions on how to 'properly' taste test a small chocolate bar - it was great to slow down and really enjoy the experience. But that wasn't the end - the final room was a surprise - LOTS of chocolate varieties to taste test, so much that we were a bit overloaded and didn't try every one.

Maison Cailler also had an option to make your own chocolate, but that was a bit pricey for our family, but we could see the 'chocolatiers in training' through a glass window having a lot of fun.

This was probably the best tour of this type we've ever been on!
