With some terrific road trip options in the surrounding area, having your own car makes good sense. Without one, it’d be much more difficult to explore everything that Old Town Colmar, 45 miles away, has to offer. Little Venice ought to be high up on your list here. Colmar Christmas Market and Collegiale St-Martin are interesting attractions too. Don’t skip Karlsruhe City Centre either! Just 40 miles away, Karlsruhe Zoo, Schloss and Botanical Garden are must-sees here.
