With some terrific day trip options in the surrounding area, renting a car makes sense. Without one, it’d be much more difficult to explore all that Old Town Colmar, 45 miles away, has to offer. Little Venice should be at the top of your to-do list here. Colmar Christmas Market and Collegiale St-Martin are awesome attractions too. Karlsruhe City Centre is another great option. It’s 40 miles away and offers a range of interesting things to do. Karlsruhe Zoo, Schloss and Botanical Garden are just the start.
