Starting Point and Logistics

The adventure begins at Honokohau Marina North Boat Ramps, a straightforward location about 4.5 miles south of Kona Airport. It’s easy to find, with clear signage after turning into Honokohau Harbor. The check-in involves a short walk to the pavilion next to the public restrooms, where you’ll meet your crew and get ready for the trip.

What makes this tour stand out is its small-group environment—only 24 passengers maximum—making it easier to enjoy personalized attention from guides and crew.
