Make the most of your underwater adventure
Hawaii law requires reef-safe sunscreen. Look for mineral-based products without oxybenzone or octinoxate. Many tours provide it.
Morning offers the calmest water, best visibility, and most active marine life. Afternoon winds often create choppier conditions.
Keep 10 feet from sea turtles and 50 feet from monk seals. Never touch coral—it's alive and fragile. Look, don't touch.
Spit in your mask and rinse before entering the water. Or use baby shampoo. A fogged mask ruins the experience.
Better sun protection than sunscreen, and it keeps you warm in the water. Most tours last 2-4 hours—you'll be glad you wore one.
The best snorkel spots are offshore. Tours provide gear, instruction, and take you to locations you can't reach from shore.
