We had not returned to the Fern Grotto for 36 years, and with so many visitors, pollution, etc, did not know if we would still find it beautiful. We went upriver with the Smith boats--a family business that has been on the Wailua River for years and happily discounts seniors and special needs. It's a short walk from the pier to the grotto. And, yes, the grotto is still enchanting with its little waterfall, misty ambiance, and a little music and dance from the Smiths.

I had read about this adventure as something low cost to do on the east side of Kauai. After exploring waterfalls on the east side we ended up at the Fern Grotto boat tour. I hadn’t done enough research beforehand to look at the boat schedule or realize you can purchase your tickets online. We arrived just before the last tour at 3:30, rushed inside to buy tickets ($30/adult) and jumped on the boat. Everyone was super friendly and patient with us. I am so glad we arrived just on time. On the way to the grotto, the boat captain gave us the history of the Smiths family, the land, and the exorbitant amount of rain in the mountains. The walk to the grotto and the grotto were so picturesque. We arrived at the perfect time to see the sun shining through the dripping water, so beautiful! The musicians played music while following us on the walk path then entertained us at the grotto and entertained us more on the boat ride back. The lead singer was funny and a lovely singer, we learned a little bit of a hula dance and enjoyed the music of the ukuleles. The total time for this tour is just over an hour and highly recommended by me and my friends.

The hosts were happy to be back in business after months of being closed. In fact, we were on the trip on their first day back in business. The walk to the Fern Grotto was lush and lovely. There was adequate social distancing on the boat. One thing they could improve, however, is that they should have two lines or better instructions for people who have already bought and paid for their tickets. Apparently, we could have gone straight down to the boat for check in instead of waiting in the box office line. Perhaps they were just out of practice.

When we arrived for our boat trip to the grotto, there were two busloads of people that arrived and went on their boat trip first. We were on our way 5 minutes later with a tour bus. It wasn't too bad as our boat was half empty.

They told stories, played music, and sang and danced on the boat ride. The fern grotto was interesting and it was nice to hear the stories and of course more singing and dancing. From what they said, it wasn't as full and lush as it used to be. Still, it was very pretty.

We were treated to some wild pigs squeaking and running around on our way back to the boat. That was fun.

If you want to see the grotto, go for it. But it's not something that I would consider a must-see. We did not opt to do the luau as we had done an amazing one at the Polynesian Cultural Center in Oahu and did not want to diminish the feeling.

At first glance, the old grotto boats and the building screamed "old and touristy". However, what made my friends and I embarrassed (we're originally from Hawaii but now live in CA & OR) was the rudeness of the boat driver. When we were ready to leave the dock, one of the passengers in the back, shouted to the boat driver "can you speak up-we can't hear back here", the boat driver shook his head (in disgust) and blatantly went to the mike and said "if you cannot hear me, move up-there are plenty of seats in the front"!!
For an establishment that is coming back from the pandemic, I would expect minimum courtesy to paying patrons. Nonetheless, he displayed attitude that we (previous locals) were totally embarrassed by.
All in all, we definitely overpaid for our 'experience' plus the grotto looked unkept. However, the female singer on our way back had a beautiful voice and was entertaining - she gets a '4'.

If ambivalent about seeing the grotto you might feel the boat trip and local entertainment not worth it. For us, it was a nostalgic return to one of the places we saw on kauai honeymoon in 1991...a year before hurricane iniki tore through the middle of the island. So the ride was entertaining...local info one way and music and hula the other. Again, some may sneer, but everyone did get up to join the dance. So get over yourself! The grotto is still lovely. Kauai is just so magical and tropical.

The fern grotto reminded me of a trip to the redwoods of California. For years I saw the post card pictures of the huge tree you could drive through. Same goes for the fern grotto river Cruise. Go thirty minutes the boat takes you leisurely to the dock while you hear some history of the Smith family and some facts about the river. Once you get to the point of disbarment, you meander through a rainforest path filled with beautiful native flora then you arrive at the filled in grotto, watch a hula and are rushed back to the boat. Seems to me more than 25 minutes could be allowed to photograph and take in the beauty at least since the grotto barely baring any ferns is a disappointment. Thirty minutes back then with some entertainment. Don’t get me wrong the people/family are supper. I guess my expectations were a bit higher.

This was ridiculous. I very seldom leave reviews but I want people to know what to expect. They packed 2 large full boats onto a small wooden platform to view the grotto. Some people did not even fit, they had someone speak but most people could not hear. It could have been a good experience if they had broke this group into 4 separate groups.

The boat ride to the grotto was filled with history and stories of the River and family business. Once at the shore, it was an easy walk to the grotto where we had a quick entertaining show and more history. When we returned to the boat, we had musical entertainment on the ride back to the dock. Perfect way to see the grotto and learn more about Kauai.

Mellow cruise with the very knowledgeable Smith Family tour. Short ~150 yard walk via paved path to the grotto. Angelic Ukulele player singing the Hawaiian Wedding Song. Easy walk back.
