Rare boat access to waters near Ni'ihau, the private 'Forbidden Island' closed to independent visitors
Combines with the dramatic Napali Coast cliffs in one long day trip
One of the longest, most ambitious boat itineraries in this dataset
Ni'ihau is a privately owned island closed to independent tourism, making boat trips like this one of the only ways to see it at all (from the water, not landing). Pairing that with the Napali Coast - Kauai's dramatic, roadless cliff coastline only accessible by boat, helicopter, or a strenuous multi-day hike - makes this one of the most complete single-day ocean itineraries in Hawaii.
Tripreviewall's Take
One of the most genuinely unique full-day boat trips in Hawaii - just prepare for open-ocean crossings and a long day.
Good for
Travelers who prioritize seeing the Napali Coast and want the added rarity of Ni'ihau
Confident boat travelers comfortable with a long day on open water
Worth knowing
This route crosses genuinely open ocean channel water, which can be rough - seasickness precautions (medication, a good breakfast, avoiding the boat's stern) are worth taking seriously
This is a full, long day - pace and sun exposure should be planned for accordingly

Google Maps — Summarized by Our Team
Ni'ihau/Napali combination boat trips are widely recognized across independent Kauai travel resources as one of the island's premier full-day excursions, specifically because Ni'ihau's private status and the Napali Coast's roadless geography make both areas otherwise inaccessible to typical visitors.
