It’s included in standard admission and is perfect for creating unforgettable family memories. Families can go multiple times throughout the day, as long as queues allow. The experience mimics a real reef dive but in a controlled, lifeguard-supervised environment ideal for first-timers.

Little Steps Insider Tip: The water can feel chilly at first — warm up in the wave pool or lazy river beforehand. Masks can fog or leak slightly; practice fitting them properly on the edge before starting your lap.
