I always recommend visiting the Park of the Aqueducts and the Ostia Antica archeological site.But I think the Colosseum, Trevi Fountain, and Mouth of Truth attractions are overcrowded...I would never say certain attractions have no merit. But after years of interacting with travelers, I understand that people want alternatives.Luckily, Rome has priceless art and artifacts around every corner.Here are five popular attractions that are worth visiting... The Capitoline MuseumsBasilica di San Giovanni in LateranoThe Park of the AqueductsBasilica of Sant'AgostinoOstia Antica ...and five you might want to skip.. Vatican Museums are overcrowdedYou can get a good view of the Colosseum...
