Bring reef‑safe sunscreen
The course is exposed and sun reflects off the water—use reef‑safe SPF and reapply after water play.
Wear closed water shoes
Grip matters—slick surfaces and climbing elements are easier with snug, non‑slip water shoes.
Know the age rules
Kids 4–6 are limited to the Keiki Course; ages 7+ can access the full course, so check ticketing before arrival.
