Glass-Bottom Reef Tour

Explore Hawaii’s underwater paradise without getting wet. Ride aboard the Marian, a 36-foot glass-bottom boat specially designed to cruise within inches of the reef. Throughout your adventure, an onboard narrator will share fun and interesting facts of the sea, historic points of interest, Hawaiian history, and other fascinating information about the area.

Have your camera ready to capture pictures of the stunning coral reef, colorful tropical fish, and fascinating marine life. Take in the breathtaking vistas of the island's rugged shoreline as the boat cruses along the historic Kona coast. Sometimes spinner dolphins or seasonal humpback whales (December to April) visit the bay near enough to view. The Marian is designed for comfort, with shaded seating as well as an open-air bow to catch some sun. The boat departs directly from the Kailua Pier, allowing you time to enjoy other excursions or a stroll through the village.
