Bumper Tube

$52 per person. You are on your tummy, your face just inches from the water and the wake of a jet ski. Sound wet enough?  Don’t let go!

Bumper Tube: Want Wetter? Try Submerging!

You Didn’t Come to Hawai`i to Stay Dry

You are on your tummy, your face just inches from the water and the wake of a jet ski. Sound wet enough? Whether you are in Maunalua Bay or the Hawai‘i Kai Lagoon, our advice is simple: don’t let go! The result will be momentary, total immersion. In Hawaiian waters!

This Can Be a Family Experience

Lot of kids challenge their elders to join in. This is one of the reasons we want even would-be observers to wear a bathing suit.

Want Something Slightly Dryer?

Banana Boats are a bit more tame. You get to stay in a seated position, assuming you master hanging on! Everyone wears a life vest.
