Little Steps Insider Tips:

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.
Relax and let the gentle current carry you along for a longer, calmer experience.
Arrive early! Rainbow Reef can get busy — go first thing in the morning for shorter queues.
Check the weather before going. Outdoor attractions may pause during lightning — pick a sunny day for the best experience.
Stay calm, move with the current and never try to touch the fish — they’re friendlier when you let them swim past naturally
If you have a favorite snorkel mask, bring it along! You can use it.
