About

Amazing undersea garden sights await adventurers aboard the semi-submersible Nautilus, designed after America's first nuclear powered submarine, the USS Nautilus. Join our captain and his crew on an exploratory mission that is both educational and entertaining. This vessel features a fish food feeding system launched by torpedo buttons so you can feed the fish from your seat (for an additional charge).

Fire One! Fire Two! You have not entered enemy waters; you are now in a marine preserved sanctuary where a feeding frenzy delight seafarers. Seasonal evening missions may also be offered for viewing nocturnal sea creatures active only after dark!

Tours are approximately 45 minutes and leave from the green Pleasure Pier. Seasonal evening missions may also be offered where explorers can view nocturnal sea creatures active only after dark.
