Public transportation in Rome is provided by buses, metro, and trams. Consider buying a multi-day pass for convenience. Taxis are readily available, but they can be expensive. Rome is also walkable, and renting bikes is a great option to explore the city.
Cost: €30 for a 7-day public transportation pass.
If you have more time, consider visiting **Ostia Antica** for a day of ancient Roman ruins. If you have less time, remove the trip to **Tivoli** and **Villa Borghese Gardens**. Reserve tickets in advance for popular sites such as the **Colosseum**, **Vatican Museums**, and **Borghese Gallery and Museum** to avoid long lines. Remember to dress appropriately for religious sites.
