Fern Grotto, Kauai
(2.5/5 based on 320+ reviews on the web)
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.

  • There was a band on the boat with wonderful singers who performed and hosted the boat ride. It was charming and a mellow and pleasant way to travel to the grotto. The staff were all lovely and funny. ...  more »
  • We rented a canoe from the little Hawaiian village and paddled the short 5 minutes upstream to Fern Grotto. It was a really short distance, but the canoe "parking" was very limited- and there was only...  more »
  • Did this trip just over a week ago. Not worth $20 & I wished we had spent our time & money elsewhere. There is very little to see @ the Grotto because ferns have been decimated by a hurricane.

  • Awesome experience. Friendly and knowledgeable staff. Wonderful walk through rainforest for all. Kids loved the whole experience.
  • It's a nice and easy trip up the river, but its way crowded with tourists of the worst kind (people were literally rude over seating availability to each other on the way up, really dumb). You walk like ducklings in water on the way up to the grotto after the boat ride, and again the crowds provide entertainment through stupidity by setting a turtles pace up the paved path. You can't actually walk up to or into the grotto, and the vantage point/stage they have built is so low (compared to the grotto entrance) that it literally ruins any attempt at composing a decent shot with a camera. On the boat ride, as well as in the grotto, there are some local guys and girls singing Hawaiian songs, tho at least two of the people consistently strummed the wrong chords and sang out of key. Overall I'd skip this knowing what I know now...
  • Great trip, beautiful grotto and freindly staff!
  • So beautiful and had excellent tour guides
  • The trip was saved by the local Hawaian musicians/guide on the boat ride. The cave is a bit disapointing, however the short walk is cool if you like plants and wanna see how local rainforest looks like :) Worth the 20 dollars!
