Holo Holo Charters is a pretty diverse boat tour operation. They are professional and offer a range of tour options with their fleet of boats. For an action experience, the rigid inflatable is a perfect choice. Choose the sail or power catamaran for a more calm, relaxing cruise. This is another operation that has been around for quite awhile.
Holo Holo offers charters to Napali and Niihau.
The only setback for taking this tour is the long drive from Princeville to Port Allen. Give yourself at least 1.5 hours for the drive.
