If you've had your fill of sun and sand, laying on the beach, or hiking through the rain forests of Maui and are looking for a relaxing indoor recreation, this is a good place to stop.
It's a little bit pricey at $18.50 for adults and $12.50 for children, but if you can afford it, this is a great substitute for scuba diving to see the local marine life.
It's a very well-put-together Ocean Center with some very impressive specimens. The seahorse tank I found incredibly interesting, and there aren't many who won't appreciate the 750,000-gallon open ocean tank, where you can stand and watch a host of sharks swimming along the glass, and wander through the tunnel in the tank, where you can get a 240-degree view and manta rays swim right overhead.
They have an excellent gift shop and free parking. This would be a great thing to do with the family or for an informative and relaxing afternoon indoors.
They are open daily from 9 to 5pm. And as with most things on Maui, it is fairly easy to get to.
Take Highway 30 from west Maui toward south Maui, and just past the Ma'alaea Harbor turn right on Ma'alaea Road.
