Neuchâtel is one of the 26 cantons which make up the Swiss Confederation. The canton is situated in the northwestern part of the country. Its principal geographic feature is Lake Neuchâtel. The lake, which is prominently featured in the video, is nearly 40 km long (about 28 mi.) and has a maximum depth of about 150 meters (500 ft.). It's the largest lake that sits entirely within Switzerland. You can see this beautiful region from a bird's eye perspective in this drone video by AboveTheClouds.
