Lausanne Transport Card
If you stay in a hotel and you pay the overnight “taxe de séjour”, you get automatically the Lausanne Transport Card for free. It gives you free and unrestricted access to all public transport services in the city (bus, train, metro). It is valid for the duration of the reservation, including the arrival and departure days (maximum 15 days). In the event of checks an identity document must be presented.
Moreover, you benefit from substantial discounts on the boat crossing between Lausanne-Ouchy and Evian, souvenirs and the admission price to various municipal and private museums.
Be careful! If you take the public transport with a bike, you have to pay an added fee which represents the price of a full price ticket.
