The Mouettes Water Taxis in Geneva are an excellent (and are free with a travel pass provided by your hotel if you're visiting) way to cross the lake. The boats run frequently and on time, and the short trip offers beautiful views of the city from the water. Staff are friendly and helpful, making it a convenient and enjoyable experience for tourists.
Highly recommended for an easy connection between lakefront areas offering a pictureseque experience and great views of the Jet D'eau.
