If you have more time, don't miss a visit to the Strasbourg Museum of Modern and Contemporary Art or explore the area surrounding the Parc de l'Orangerie. For an extra dose of culture in Colmar, visit the Toy and Little Train Museum or take a 30-minute train ride to the charming town of Riquewihr. If you have less time, prioritize visiting the Notre-Dame Cathedral and Unterlinden Museum as these are the highlights of each city.
