These yellow boats function as transport between the different shores of Lake Leman in Geneva and are a delight for tourists as well as locals. Tourists enjoy a pleasant lake crossing, and locals use them as a convenient and cheap method of transportation to get to work. The same bus ticket (3.50CHF) can be used in any of the 4 lines: M1: Pâquis - Mollard - Pâquis. M2: Pâquis - quai Gustave Ador - Pâquis. M3: Pâquis - Genève-plage - Pâquis. M4: Genève- plage - Perle du Lac - Genève-plage. They run every 10 minutes from 7.30 am - 18:00 pm (approximately and depending on the line) and I advise going on a sunny day, as the lake is calmer.
