About Sirena
Sirena joined Oceania Cruises in 2016 after sailing for another line, making her the most recent addition to the fleet’s R-class quartet. She was extensively refurbished on arrival and later updated with Oceania’s newer interiors, giving her a fresh, contemporary feel while preserving the intimacy of the original design. Sirena is a little different from her sisters in dining, offering Red Ginger and Tuscan Steak as her specialty restaurants. She sails a wide mix of itineraries, from the Mediterranean to the Caribbean and South America, appealing to guests who enjoy a small ship with excellent food.
Best for: Travelers who want a refreshed, small ship with Oceania’s food-first approach and a relaxed, adults-oriented atmosphere.
