Mobility Ticket
Each guest staying in a hotel in Basel, receives a Mobility Ticket upon check-in. This allows free use of the public transportation system in the city of Basel and its environs (zones 10, 11, 13 and 15, incl. the way to and from the Airport). The ticket is valid for max. 30 days. On the day of arrival, the reservation confirmation from the hotel guarantees a free transfer by public transport from the train station or the EuroAirport. So please don't forget to print your hotel confirmation and to take it with you on the tram or bus!
