Admission runs about $40 for adults and $27 for children ages 3-12, with toddlers under 3 free. This is the go-to indoor backup on Maui when it rains or when the sun is too intense for little ones. The walk-through shark tunnel and open-ocean tank are absolute showstoppers that even babies respond to. Allow 2 to 3 hours and use the stroller throughout since the facility is fully flat and accessible. Grab lunch at the on-site restaurant with ocean views to round out the visit.
