Raphael house (open 3-5 pm or by appointment ), Archeology Museum, historic churches, Corso Centocelle and Corso Marconi shopping areas, public markets. For best pizza-Mastro Titta, best gelato-Chalet del PIncio. My favorite restaurants are Da Baffone, Corso Garibaldi for al fresco dining , and Bistro at Hotel San Giorgio in the evening. Locals favorites include Trinity Pub on Via Trieste , Holo's vegan cafe, Via Istria. For beaches -Locals go to rocky San Agostino, a short taxi ride away, or Santa Severa, a 10 minute train ride south towards Rome, with sandy beaches and a castle .
Mornings are best for shops, museums, churches and markets are open. In summer, avoid the hottest midday hours and don't miss the spectacular sunset on the sea.
Civitavecchia is very safe with lots of pedestrian areas. Watch out for motorscooters and buses when crossing streets.
