• Fern Grotto - River Boat
  • Features

    Fern covered, lava rock grotto on the Walua River with daily boat tours.

Only accessible by boat or Kayak, the Fern Grotto is located about two miles up Kauai’s Wailua River, the only navigable river in the State of Hawaii. The grotto is a cave of lush ferns growing on the cave walls as a result of moisture seeping from the irrigation of sugarcane growing on the cliff plateau. When the sugar industry had its last days, the ferns began to die off until restoration efforts returned moisture to the area. Hurricane Iniki and a severe flood in 2006 also wreaked havoc upon the cave.

The best way to get to Fern Grotto is to take one of the Wailua River Cruises. On your twenty-minute trip up the river, you will learn about the history of the Wailua River Valley while enjoying Hawaiian songs and entertainment. The entire tour takes about an hour and a half.  Be sure to bring your camera, as this tropical valley offers many photo opportunities that you will not want to miss.
