The Roman harbour was rebuilt in the 1980s and is now a marina for yachts and tourist boats. From the 2nd century BC, it was Antalya's more important transportation route until the end of the 20th century, when it was replaced by a new port 12 kilometers west of the city. There is a marina for cruise ships in the harbour of Rome. Some tours go to Kemer, Phaselis, Olympos, Kale (Demre) and Kaş. There are a variety of short sailing itineraries, including 1-hour, 2-hour, or 6-hour cruises, including visits to the Lower Duden waterfalls, Antalya Islands bays and some swimming beaches.
