Written for Explore: Rome, Italy, known as the Eternal City, truly lives up to its name with an endless array of activities, sights, and culinary delights that could keep you busy for an eternity.
However, if you only have a one-day trip planned for Rome, you’ll have to be more selective with what you see and do. One thing to consider when visiting Rome for only one day is how much walking you are comfortable doing. While many of the locations we recommend are within walking distance of one another, if you would rather take a cab or car service, you’ll want to plan for travel time between areas.
