You reach the reef below the Captain Cook Monument only by boat or by a two-mile paddle across the bay from Nāpōʻopoʻo. Sea Paradise runs the Hoku Nui, a 50-foot sailing catamaran, there from Keauhou Bay each afternoon on a 3 hours round trip.
The crew stays in the water with you for the whole snorkel and points out and names the fish for kids and first-time snorkelers. Before anyone gets in, they run a site briefing. On a recent trip one of them called out a spotted eagle ray as it crossed under the group.
The Hoku Nui leaves Keauhou Bay at 2:00 pm and covers about four miles of Kona coastline to the bay, roughly 45 minutes. The leeward water is usually calm in the afternoon, so the crew hoists the main sail but motors much of the way south. The trade winds pick up on the return north, and the boat sails that leg. Snorkeling in the bay runs about an hour.
Kealakekua Bay has been a State Marine Life Conservation District since 1969. The reef has dense coral and heavy fish life in clear water. Over the coral you’ll see yellow tang, Moorish idols, moray eels, and humuhumunukunukuapuaʻa, the reef triggerfish. Spinner dolphins turn up on the sail south often enough that the crew watches for them, and humpback whales pass this stretch between December and April.
The Hoku Nui is licensed for 49 guests, and a full boat can feel crowded. Sea Paradise says it usually runs closer to three quarters of that, so full afternoons are the exception. Full-face snorkel masks aren’t allowed on board, a safety rule. It’s a shoe-less boat, so bring sandals you can slip off. The tour isn’t accessible for guests with mobility limitations.
Where to meet the boat at Keauhou Bay
Check in at the finger pier at Keauhou Bay about 15 minutes before departure; the crew wears blue shirts. Parking on Kaleiopapa Street is free and a 3-to-5-minute walk from the pier, and public restrooms sit at the east end of the lot and on board.
The Hoku Nui departs at 2:00 pm and is back by about 5:00 pm. Allow extra drive time, since Kailua-Kona traffic slows on the way to Keauhou. Bring swimwear, a cover-up, sunglasses, a hat, a towel, and reef-safe sunscreen.
What comes with the tour
Everything you need for the water is included: mask, fins, snorkel, a flotation noodle, a life jacket, and fish identification cards. Water, soft drinks, and local juices are poured throughout, and light snacks, or pupu, come out on the return leg. A fresh-water rinse station on deck washes off the salt after you get out.
Alcoholic drinks are available for purchase with a credit card once the water portion is done; BYOB isn’t permitted. GoPro rentals are available on board, and the 16GB SD card is yours to keep.
The tour is $125 for adults and $75 for youth; infants are $45. Cancellations need 24 hours’ notice, or 72 hours for private charters and groups of ten or more.
