Peek into Kona’s underwater paradise without getting wet. Cruise aboard the Marian -- a 36-foot glass-bottom boat specially designed for viewing the clear waters of Kona. Your tour begins as you board the vessel at Kailua Pier.

Gliding over the reef, you will see and learn about the vibrant tropical fish, coral colonies, and other underwater wonders.

Have your camera ready as the boat approaches Ship Wreck Rock, where the glass is inches from a majestic pinnacle teaming with colorful marine life. Marian was custom-made to glide right over the rock making for some special photo opportunities.

At the "drop off", you’ll see the bottom fall away to more than 100 feet deep.

Frolicking dolphins or winter humpback whales are always a special bonus.

The on-board naturalist and friendly crew share their love of the sea. This tour is a marvelous choice for those interested in a relaxing way to learn about and see Hawaii’s aquatic wonders.


This excursion was voted ‘#1 Travelers Choice’ by Trip Advisor. Wear comfortable shoes. The boat features easy boarding and shaded, cushioned seating. Wildlife sightings are likely but are not guaranteed.
