This attraction can only be reached by a boat trip up the river....and that is a very pleasant experience for an hour or so (round trip.) The grotto itself is nothing...it can't even be seen because the cave is closed to the public as being unsafe. After the boat trip up the river, one walks quite a distance on a... More

I thought this was going to be the beautiful part of our tour picked for Kauai. Big disappointment. Entertainment was tired. Main singer good. But the others acted like they couldn't wait for it to be over. My sentiments exactly. Don't bother!

I was very excited to see the Fern Grotto. It was a great boat ride up the Wailua River. But, when we arrived at the Fern Grotto's dock, this older Hawaiian lady guide started spewing negatives about not talking when she was talking (when we weren't even talking), about privacy issues and NOT posting on YouTube of people going to...

The boat ride to the grotto was about 30 minutes and was very relaxing. The staff was very friendly. They entertained us with traditional Hawaiian music one way, and the captain told some of the history on the return trip. Once you depart the boat at the grotto, the grotto is about a 5 minute walk up a paved trail.... More

The grotto is interesting, but not the best view. The boat ride is relaxing but I would recommend a kayak if you want to see it. It is difficult to hear the guide and he is not very captivating. The musicians are average. If you do go sit on a side closest to when you enter the boat. Get off... More

There are really two reviews here, the first is the boat ride. It is a great attraction. Very well organized, reasonably priced at $20 per person and entertaining. The staff is very nice, the commentaries informative and we really enjoyed the songs and dances on the way back. The grotto is pretty but after such a build up, it was... More

We were happy that we went to Fern Grotto and were prepared to see a grotto that had been severely damaged in the last hurricane. The people who run the boat ride were very nice, informative and entertaining. There was singing and dancing as well as stories and information. The trip along the river was so pretty and relaxing. It... More

Was on a Smith family boat ride with a walk into grotto. Walk in was short and not to difficult. Had music and dancers on boat that were good. If have time worth the trip.

We went on the Smith's family Wailea river cruise. I was the only one in our party of four that had been here before the hurricane and mud slides, so my view may be different than someone who had not seen it when it was in full glory. The ride was relaxing and the crew was very friendly. While on... More

Lovely serene trip on the river and only a short walk to the grotto and it is wonderful Hula dancing on the boat. Worth the time and not expensive $20.00
