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

Just weeks before I visited the area had rain so many colourful plants & flowers were seen walking from the boat wharf to the Grotto. the Sword ferns growing down form the cave roof were amazing. The group singing The Hawaiian Wedding Song was enjoyable to watch & hear. The boat trip up & back was enjoyable. A worthwhile trip... More

The ferns here grow upside down. We arrived on a boat and were treated to native musicians and hula dancers. After a short hike we arrived at the grotto to view the ferns and take pictures. The plants all around were very beautiful.

A wonderful place to visit, peaceful, scenic and the dancers and singers were superb, can understand people getting married here, at one with nature. Truly sublime.

We stopped here while visiting Wailea Area. Took a canoe ride. A little pricey but our teenagers liked it. The Grotto itself isn't a real "Wow" attraction but the overall area is pretty and worth seeing.

We traveled to Kauai during the rain/hurricane season which means a lot of rain. We decided to take the Fern Grotto river cruise because the boats were covered and the cost was only $20 a person. The boat ride is very short to the grotto. Once docked, there is a short walk through the rain forest to the grotto. There... More
