Fern Grotto, Kauai

#9 of 23 in Nature in Kauai
Cave Nature / Park
Surround yourself with some of the most beautiful nature the island of Kauai has to offer by visiting Fern Grotto. The lush lava-rock grotto is one of the island's natural wonders--a natural amphitheater renowned for its acoustics, it's considered one of the most romantic locations in the whole of Hawaii. The only way for visitors to reach the sight is by taking a boat on the Wailua River. There are numerous companies that organize river cruises, while the more athletic visitors can also kayak to the grotto. For safety reasons, entering the grotto itself is prohibited, but there is a viewing platform from where you can admire the sights and sounds. Our Wailua travel itinerary planner makes visiting Fern Grotto and other Wailua attractions simple, and helps you make a travel plan personal to you.

  • A nice day way to spend an hour or two while the rest of your family is doing something to adventurous for you! Narration on the trip to the grotto and Hawaiian music and hula dancing on the way back....  more »
  • THis is not a very expensive place to visit. Overall, it gives you a small taste of Hawaii as you learn a little of the area and are entertained as well. Is it a Vegas show? Definitley not. But for th...  more »

  • After 2 hurricanes hit the area, visitors can no longer hike up to or into the fern grotto cave. It is a beautiful tropical area.
  • My parents and husband and I took the 9:30 a.m. tour this morning (a Sunday). It was a very relaxing and enjoyable tour. My parents are in their 80's, and they were able to do the nature walk. Uncle Kimo and the performers on the boat had great warmth and "aloha spirit." They were very friendly and talented. We learned a lot about the Hawaiian history and culture from the captain. I highly recommend this tour!
  • The tour to Fern Grotto was really nice. With locals singing and dancing.
  • Beautiful river cruise, music and performers need updating.could not hear they well. Sound system old. Area and walkway around cave and fern grotto needs more beautification. Looks like it is unkempt by grounds people. But for $20, it was okay.
  • After a busy and tiring couple of days hiking and snorkeling the Smith Family boatload to the Fern Grotto was a perfect quiet afternoon adventure.
