Fern Grotto, Kauai

2.6
#14 of 24 in Nature in Kauai
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. For Fern Grotto and beyond, use our Wailua vacation maker tool to get the most from your Wailua vacation.

  • The last day of our cruise was wanting for an excursion so we picked a river boat ride down the Wailua River to a heritage trail showing an interesting Fern Grotto. The ferns are now regrowing in the ...  more »
  • The cave itself is nothing special, there you enter more some years ago when it was closed due to flooding. Distinctly the nature walk. To reach it you do a boat trip. A nice experience on the only navigable river in Hawaii. The ride on the boat is with traditional dances and explanations about the history, culture and geography of the place.

  • Unfortunately we cannot enter this site, just watch out, because it closes very early 16:00. Therefore, the ideal is to go early so I could enjoy.

  • We are having a great time in Hawaii, This island is so green and lush it's unbelievable.
  • Great place to visit. Small waterfall hidden in the surroundings.
  • Great time. Well done.
  • 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!
  • 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.
