Smith’s Fern Grotto Cruise

For a relaxing, peaceful couple of hours, take a short cruise up the scenic Wailua River to the lush Fern Grotto, a fern-covered lava cave. During the two-mile cruise on Smith’s open-air boats, you will be treated to live music and stories of Hawaii. Once there, you will disembark and take a short nature hike to the grotto where you will spend time on the observation deck. The entire trip takes about an hour and a half to two hours.

The Fern Grotto tours are conducted by Smith’s Kauai, also famous for their garden luau. Boat tours depart Monday, Wednesday and Friday from the Wailua Marina State Park at 9:30 A.M., 11:00 A.M., 2:00 P.M. and 3:30 P.M. If you are going to the luau after the boat tour, select the 3:30 P.M. time.

The Fern Grotto is a popular site for weddings. At one time the weddings were performed in the grotto, but today weddings are performed on the observation deck. See Smith’s Kauai website for details.

See a filming location for Raiders of the Lost Ark on the Fern Grotto river cruise. This is where Harrison Ford runs from natives in the Peruvian jungle at the beginning of the movie.


Seasickness is usually not an issue on this slow and smooth boat ride.
