And if your work in BSL
, on your way to Strasbourg, don't forget to visit Colmar, the villages around, and have a meal in Illhausern, at the Auberge de l'Ill.
And if you don't have it, just don't forget the Musuem pass. It gives you free access to about 140 museums in Basel area, Alsace and Germany.
(When you know the price of the Auto Museum in Mulhouse, or the Ecomusee d'Alsace, in 3 to 4 days, it is reimbursed, and the pass is valid for 1 year)
Sorry, but the link is only in French and German
