Top 15 Marvelous Facts About Lake Geneva

One of the most amazing lakes in the world straddles the border of two European countries. It’s one of the magnificent Alpine lakes that is located just north of the most famous mountain range in Europe.

In this article, you’ll discover some of the most interesting facts about Lake Geneva, an incredible feat of nature on the European continent.

1. It’s located on the border of Switzerland and France

Lake Geneva is named after the second-most populous city in Switzerland which is located in the utmost southwestern corner of this magnificent lake.

The city of Geneva borders France and the same applies to the lake, making it one of the most famous lakes in France as well. This is in the western part of Switzerland and just east of the second-most populous metropolitan area in France, Lyon.

60% of the lake is located in Switzerland, within the cantons of Vaud, Geneva, and Valais, while the other 40% is located in France, in the department of Haute-Savoie. It borders the Alps in the eastern part.

2. The French name for the lake was already used during the times of Julius Caesar

The French name of Lake Geneva is “Lac Léman,” a name that was derived from the Latin name of the lake “Lacus Lemanus.” The exact origins of this name remain unknown.

We do know that this large body of water was already referred to as such during the time of Julius Caesar in the 1st century B.C. That’s quite an extensive history.

The name transitioned to “Lacus Lausonius” during the Roman Empire, the same name given to a town in the region. This eventually became Lac de Lausanne in the Middle Ages which is the French name of the English name of the lake.

3. It’s the largest lake on an important river in Europe

The lake has a surface area of 580.03 square kilometers (224 square miles) which makes it the largest lake in Switzerland.

The approximately 60% of the lake’s surface area in Switzerland is 345.31 square kilometers (133.32 square miles) while the remaining in France covers 234.71 square kilometers (90.62 square miles).

It’s also the largest lake that is situated on one of the most important rivers in Europe, the Rhône River.

This river emerges from the amazing glacier fittingly called the Rhône Glacier and flows west and south through Switzerland and France. It eventually releases into the Mediterranean Sea near the city of Arles in southern France.

4. The lake is divided into 3 geographical regions

The crescent-shaped lake is located within 3 distinctively different geographical locations. That’s why it’s divided into 3 regions as well:

  • Upper Lake (Haut Lac) – The eastern part of the lake that borders the Alps.
  • Large Lake (Grand Lac) – The central part of the lake that is the deepest and covers the biggest area.
  • Small Lake (Petit Lac) – The utmost southwestern part of the lake near the city of Geneva.

5. Which part of the lake is the most beautiful to visit?

The lake is situated within a mountainous region, but some parts of the lake are simply more beautiful than others. The southern shore borders the Chablais Alps, one of the multiple mountain ranges in the Western parts of this magnificent range.

Some parts of the lake allow views of the highest peaks in the region, including the Mont Blanc. This is the highest mountain in Western Europe with an elevation of 4,807.81 meters (15,774 feet) above sea level.

It’s fair to conclude that the eastern part of the lake, which borders the Western Bernese Alps, is the most beautiful because here you can admire the lake with the true Alpine landscape as its background. This is reminiscent of the Alpine lakes in Italy such as Lake Garda.
