Beautiful Lake Leman is the most striking feature of Geneva with its Jet d'Eau, a water jet, in the middle. Well, the water jet may not be that special, but it is undeniable that the lake is spectacular. A very interesting way to cross it is in one of the cruise ships. The views of the lake, the city and the Alps are very beautiful, and if it is a clear sunny day, the trip is really worth it. Indeed, the Geneva Tourist Office sells packages for hotel + transport card + lake cruise that are really well priced.
