While Europe’s major cities are always fun and full of attractions, day trips can sometimes enhance travel experiences. We’ve taken it a step further many times and visited the neighboring country. The close proximities of countries in Europe makes it easy to visit multi-country visits in one day. Day trips are defined here as between 30 minutes to two hours from the city center by train, bus, car or boat. These are day trips we have actually taken with the kids and enjoyed. Of course, these city pairs can also be done in reverse. We hope these ideas will help with your day trip plans when visiting these cities.
