A casual cruise up the Wailua River to the Fern Grotto aboard a motorized riverboat is one of Kauai’s oldest and most popular attractions.

River cruises depart about every half hour throughout the day from the south side of the Wailua River.

Most tour companies share with passengers the music, dance and legends of the Wailua area, which is considered one of the most sacred areas of Kauai. Every seat aboard the riverboat offers a great view during the 40-minute trip to the Fern Grotto.

Tropical grasslands line the river and cloud-capped Mt. Waialeale looms in the background, adding an element of mystique to the trip.

Upon arrival at the lush, green Fern Grotto, you disembark and take a short walk to a platform within the fern-draped cave mouth.

There, Hawaiian musicians serenade you with “The Hawaiian Wedding Song” and other traditional music. The acoustics within the grotto are remarkable and greatly enhance the singing and guitar playing.
