The Carnival Vista features three main swimming pools, each offering a different atmosphere for passengers. The primary pool is the Beach Pool, located mid-ship on Deck 10 (the Lido Deck), which serves as the social heart of the ship with music, the "Dive-In Movies" screen, and easy access to the BlueIguana Tequila Bar. At the rear of the ship is the Tides Pool, which offers a quieter vibe and stunning views of the ship's wake. The third pool is the Havana Pool, an exclusive, infinity-style pool located at the aft of Deck 5. In 2026, access to the Havana Pool is restricted to guests staying in the "Havana" staterooms and suites during the day, though it may open to the public in the evenings. In addition to these three pools, the ship features six outdoor whirlpools and the "Carnival WaterWorks" park, which includes the Kaleid-O-Slide and other interactive water features. For those seeking true relaxation, the "Serenity Adult-Only Retreat" offers additional whirlpools, though not a full-sized swimming pool, providing plenty of options for cooling off in the Caribbean sun.
