You could explore Liechtenstein in one day
With just 62 square miles, the Principality of Liechtenstein is the fourth-smallest country in Europe. That’s smaller than most major cities around the world, about half the size of the city of Atlanta, with a little less than 10% of Atlanta citizens. This is not a big place. But Liechtenstein has museums, quaint mountain villages, great skiing, and beautiful mountains, just like its larger neighbors. It’s just as picturesque and makes a perfect day trip!
It may be a doubly landlocked country (surrounded by countries that are also landlocked), but the beautiful Rhine River flows along its border. If you also have a bucket list for world travel, it’s easy to add a day trip to Liechtenstein if you’re already in northern Switzerland. Currency, language, and transportation are all the same or similar to Switzerland, so you don't need extra planning.
Liechtenstein and Switzerland are both parts of the Schengen area, even though neither is in the EU. This means their borders are more relaxed. Therefore, when you arrive at the airport and go through customs and passport control, there will be less fuss.
