Not what it used to be.

This used to be a spectacular place with amazing hanging ferns and other plants, and you could go into the cavelike overhang with wonderful acoustics. Ever since Hurricane Iniki... read more

Rent a kyak, down load Elvis Presley singing Blue Hawaii to your phone, apply sun screen, and pack a lunch. Arrive around 10a.m. and start rowing. You have plenty of time so take your time rowing and enjoy the beauty and peace. When you get to Fern Grotto try to arrive between the big boat arrivals and park your kyak... More

We enjoyed our boat trip to the fern grotto. It's a beautiful trip with lots of history. I wish we had seen it in it's full glory!

We went on the cruise in the morning and all the way to the grotto we were treated to lovely live Hawaiian music and dance. There are some lovely places to photo as you sail along. The grotto itself was disappointing but the guide was quite funny and made it interesting. On the way back we were told stories and... More

I did this cruise 31 years ago and it was much better because you were able to go to the grotto and see the inside. Now you only can see the grotto from a distance from a platform. Sorry but this was boring and not worth our time .

If you just want a laid back afternoon, take this excursion. A nice leisurely float with a guide to point out interesting things along the way. A short walk after u arrive at grotto...nice relaxing trip

The river cruise to the Fern Grotto is well worth the modest price of admission. The tour guide gave very informative commentary on the various things we saw as we traversed the river. The Fern Grotto is a short walk from the dock on the river and is beautiful. We enjoyed the entertainment on the boat on the way back... More

After reading information that the Fern Grotto is not as impressive as it once was since the hurricanes doing damage, we still decided to go. If you book online at least 2 days before going, you get a 10% discount. Also they give a seniors discount of 10%, making the trip only $18. It was worth it. They give you... More

This used to be a spectacular place with amazing hanging ferns and other plants, and you could go into the cavelike overhang with wonderful acoustics. Ever since Hurricane Iniki and then another less powerful hurricane a couple of years ago, nearly all of the plants have been destroyed and now they don't even let you go into the cavelike area...

Several reviews mention that the Wailua River is unremarkable, and I just wanted to point out that this perception is due to the vantage you get from Smith's boats, which is what most tourists use to get to the Fern Grotto. Smith's uses covered boats that shut out the views of most beautiful parts of being on the Wailua, which... More

The boat ride was disappointing, the grotto itself is beautiful but you cant actually get up close to it anymore. Its definitely very touristy now. The most disappointing part of the whole tour was at the end when we were leaving the grotto the staff decided to have a full out yelling match with each other. We could hear them... More
