When you visit the Eternal City, prepare to cross a few must-see attractions including the Colosseum, the Trevi Fountain and the Pantheon off of your bucket list. Additional treasures, such as St. Peter Basilica and the Sistine Chapel, can be found in nearby Vatican City. Escape the tourist crowds by taking a twilight stroll along the cobblestone streets of Trastevere, or head to Mercato Centrale Roma to sample local delicacies like gelato and pizza.
