Sea Paradise runs the Hoku Nui, a 50-foot sailing catamaran, from Keauhou Bay each afternoon on a 3 hours round trip to the Captain Cook Monument. The sail south covers about four miles of Kona coastline and takes roughly 45 minutes. Between December and April, humpback whales are commonly spotted on this stretch. Spinner dolphins use the bay year-round. On calm afternoons, which are frequent on the leeward side, the crew motors rather than sails. Either way, the destination is the same.

Kealakekua Bay has been a State Marine Life Conservation District since 1969. The reef reflects that: dense coral, consistent fish populations, and clear water. The captain selects the snorkel sites within the bay. Before anyone enters the water, the crew gives a site briefing and adjusts masks and fins individually. On a recent trip, a crew member called out and identified a white-spotted eagle ray as it crossed under the group. The crew stays in the water with guests throughout.
The boat holds a maximum of 44 guests. Full-face snorkel masks are not permitted on board. The Hoku Nui is a shoe-less boat: wear sandals or shoes that are easy to slip off. The tour is not accessible for guests with mobility limitations.
Tour departure information
Crew meets guests at the end of the pier at Keauhou Bay approximately 15 minutes before departure. The Hoku Nui departs at 2:00 pm and returns by approximately 5:00 pm. Allow extra drive time: Kailua-Kona traffic can be slow on the way to Keauhou. Public restrooms are at the east end of the Kaleiopapa Street parking lot and onboard. Bring swimwear, a cover-up, sunglasses, a hat, and a towel.
What is included with the tour?
Inclusions cover everything you need: mask, fins, snorkel, flotation noodle, life jacket, and fish identification cards. Water, soft drinks, and local juices are served throughout. Light snacks, or pupus, are available on the return leg. A fresh water rinse station is on deck after snorkeling. Alcoholic beverages are available for purchase with a credit card after the water portion. BYOB is not permitted.
Sea Paradise has been running manta ray and snorkel tours out of Keauhou Bay since 1985. They are a member of the Sustainable Tourism Association of Hawaiʻi and contribute time and funding to the Surfrider Foundation and the Hawaii Wildlife Fund, two organizations active in reef and ocean conservation on the island.
