During one of my tours through the Provence I had the opportunity to visit the Lavender museum !
The video at the beginning teaches you all about the essential oil and it is possible to listen to it in Chinese !
The best is at the end with the boutique offering a wide range of products including fine lavender. They explain you all the benefits of those products and my personal favourite is the pure essential oil that can be used at so many different ways !
As the Lavender museum is not easily reachable by public transportation means, the best way to visit it, is to book a minibus excursion. Provence Reservation includes the entrance ticket for this museum in several tours, have a look at their website and make your choice !
