Kona Afternoon Snorkel to Captain Cook Monument at Kealakekua Bay
An Afternoon Sail to a Protected Reef
Depart Keauhou Bay at 2:00 PM aboard the Hoku Nui, Sea Paradise’s 50-foot luxury sailing catamaran, and head north to the Captain Cook Monument at Kealakekua Bay. The bay has held Marine Life Conservation District status since 1969. No fishing. No anchoring.
That protection shows underwater. Coral grows without anchor damage, and marine life density runs noticeably higher than at snorkel sites open to general access. Sea Paradise has been sailing this coastline since 1985, so the crew reads afternoon conditions well and knows where the water usually sits calmest.
Keep your mask ready on the way in. Spinner dolphins sometimes appear at the bay entrance, and the reef below holds spotted eagle rays, Moorish idols, yellow tang, humuhumunukunukuapuaʻa, Hawaiian green sea turtles, and moray eels tucked into the coral. Before anyone enters the water, a marine naturalist runs a full reef briefing so you know what you are looking at and how to float without touching it.
Honestly, the trip back is the part guests talk about. Afternoon trade winds fill the sails, and the Hoku Nui motor-sails whenever the wind goes slack. You step off at Keauhou Bay around 5:00 PM. One detail worth knowing: this tour does not stop at the Red Hill Area.

Keauhou Bay: Check-In and Departure
Check in at 1:45 PM at the finger pier at the end of Kaleiopapa Street. Do not check in at any buildings, since the crew meets guests at the end of the pier about 15 minutes before departure. Board the Hoku Nui, the 50-foot catamaran with the blue sail bag, and cast off at 2:00 PM.
Kealakekua Bay: Captain Cook Monument Snorkel
About an hour of snorkeling in the pristine water near the Captain Cook Monument, inside the marine sanctuary. Gear is aboard: mask, fins, and flotation noodle. The naturalist briefing covers the reef before you get wet.
Second Reef Session in the Bay
A second in-water session, roughly an hour, working another stretch of reef near the monument. Crew stay with the group and keep watch the whole time. Confident swimmers only, per the operator’s rules.
Sail Back to Keauhou Bay
Trade winds typically build through the afternoon, so the return passage runs under sail. Snacks come out, drinks are available for purchase by credit card, and the boat ties up again around 5:00 PM.
Before You Go
Allow extra drive time for traffic on the way down Kaleiopapa Street. Public restrooms sit on the east side of the street near the end parking lot, and there is also a restroom onboard. All snorkelers must be confident swimmers, non-swimmers cannot enter the water, and children wear life jackets. Full face masks are not permitted on this tour. Guests sign a release form before boarding, so review the health guidelines at seaparadise.com/medical/ first, and tell the staff about dietary restrictions at least 48 hours ahead. Parking at the bay fills on busy afternoons, another reason to arrive early.
