Kaumalapau Harbor, nestled on Lana’i's leeward side, offers a unique blend of natural beauty and historical significance. Originally constructed in the 1920s by James Dole for pineapple shipping, the harbor now stands as a testament to Lana’i's industrial past. The distinctive breakwater, adorned with white Core-Loc armor units, adds to the harbor's charm.

While not a typical tourist destination, Kaumalapau Harbor offers unparalleled sunset views from its stone walls. Between December and May, visitors might be lucky enough to spot whales swimming in the nearby waters. The journey to the harbor provides scenic vistas of Lana’i's dramatic sea cliffs.

It's essential to note that Kaumalapau Harbor lacks typical beach amenities like restrooms and showers, and access is restricted on certain days due to freight activity. However, its raw beauty and tranquility make it a captivating spot for those seeking a secluded escape.
