The Basel-Mulhouse-Freiburg airport, or EuroAirport, is operated by France, Germany and Switzerland. Though located in France, the airport has two sections- one Swiss and one French. To get to Saint-Louis, one must exit from the Mulhouse Bale airport at the French side (with the code MLH). On reaching, rent a car from the Sixt counter in the arrival hall. Whether you plan on driving straight to your hotel in Saint-Louis, or want to go sightseeing, a car rental service proves to be cheap and convenient.
