Start the bachelorette party with a visit to the Trevi Fountain, the largest Baroque fountain in Rome, and make a wish while throwing a coin over your left shoulder. Then, head to the Spanish Steps, where you can take stunning photos at the top and enjoy a gelato or coffee at one of the many cafes nearby.
Spend the morning visiting Vatican City, home to St. Peter's Basilica and the Sistine Chapel, where you can admire the incredible artwork of Michelangelo. After lunch, head to Castel Sant'Angelo, a historic fortress that offers great views of the city and hosts frequent events and exhibitions.
See one of Rome's most iconic landmarks, the Colosseum, where ancient Romans entertained themselves with gladiator fights and other spectacles. Next door is the Roman Forum, a fascinating excavation site of ancient commercial and government buildings.
End the bachelorette party with a visit to the picturesque neighborhood of Trastevere, known for its winding cobblestone streets, colorful houses, and artisan shops. Then, explore the nearby Piazza Navona, a lively square filled with artists, street performers, and cafes.
If you have more time, consider visiting other popular sites such as the Pantheon, the Borghese Gallery, or the Catacombs of Rome. If you have less time, skip Castel Sant'Angelo and spend more time at the Colosseum and Roman Forum. Don't forget to wear comfortable shoes and bring plenty of water, as Rome can get hot and crowded during peak tourist season.
