With more than 55,000 inhabitants, the bilingual city of Biel/Bienne is the largest city within the Three-Lakes Region and belongs to the canton of Bern. Neuchâtel in the canton of the same name is the second largest city with just under 45,000 inhabitants and Yverdon-les-Bains comes in third with 30,000 inhabitants. Also in the region is the pretty city of Solothur, considered the most beautiful baroque city in Switzerland.
The Three-Lakes Region is known for its good wine. It grows on the southern slopes of the Jura on Lake Neuchâtel and Lake Biel, but also on Mont Vully north of Lake Morat
In the Jura, two smaller towns stand out. La Chaux-de-Fonds and Le Locle were included in the UNESCO World Heritage List as urban landscapes of the watchmaking industry
Near these two towns, to the northwest of Lake Neuchâtel, is the Creux du Van rock arena. The nature reserve consists of cliffs about 200 meters high over a length of about 1400 meters. It is located at the end of a valley above wild gorges created by the Areuse River.
