Great trip on the river! The captain was very informative on the local culture. The crew performed a dance at the grotto and also performed several dances on the way back on the boat. A good value.

The boat were large and covered. The bride was smooth and pretty. Interesting commentary. Good music. Fun hula dancer. The fern grotto was beautiful especially in the rain. Nice walk, not hard. All in all. An outstanding trip for a rainy days. Must be great in the sun also.

The Fern Grotto tour was a great precursor to the Smith Family Luau. The trek was interesting, and we learned some historical facts, and saw some beautiful scenery. The hula dancing was fun (to watch). It was well worth the time

Fine way to kill 2 hours but nothing special
Activity Date: 2026/02/16 | Posted on: 2026/02/18

It is what it claims. You sit and ride up the river to a short hike to a natural feature where water drips over cavernous undercut. On tour they explained a few things but the acoustics where I sat weren't great to understand everything. Between that they sang some Hawaiian songs. All fine. Just wouldn't expect too much.

Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula
A very fun river cruise
Activity Date: 2026/02/11 | Posted on: 2026/02/15

While in Kauai with family we decided to try the Smith Family Fern Grotto River Cruise, which was an awesome choice of entertainment. We love history and learning about places we visit, so we were pleasantly surprised when the beginning of the cruise was a full narration of the interesting history and geography of the Waimea River. The crew led us to the breathtaking Fern Grotto and enhanced the experience with beautiful music. On the way back to the dock we were entertained with music and dancing, which was very fun. The trip ended much too soon! The cost was very reasonable. We would highly recommend this trip!

Aloha KNC,

Thanks for recommending us and for the 5 stars. On our hike to the falls we ask folks to at times to "embrace the mud" and while you are, Harrison is there to keep it fun, safe and informed.

And yes…some sort of aqua shoes or beater tennis shoes should work.

Enjoyable couple of hours.
Activity Date: 2026/01/19 | Posted on: 2026/01/21

The Fern Grotto trip was a lovely experience from beginning to end. First: the price is right! There are so many expensive things to do on Kauai, but we thought the $35 per person fee was worth it. The boat is wide and very stable (no waves!!) and is covered overtop (no rain and no sunburn). However the sides are completely open and we enjoyed the air and very slight breeze. The captain gave nice narration on the way to the grotto with interesting facts about the area. On the trip back, there was a hula show with singing. It was more like a family show than a Hollywood production which was fine with us. I was amazed at the care and assistance provided to a lady in a wheelchair, several who had walkers, and some with canes. Once arriving at the Grotto, the boat crew guides you on a cement path to the viewing area. Then they sing the Hawaiian Wedding Song which was nice. My younger brother was married at the Fern Grotto about 40 years ago, so that was meaningful to me. There were restrooms at the Grotto area. No food or drink is served. Tour lasted a total of 2 hours. Plenty of parking.

This was the perfect fit for us and our 3 year old. The boat is kid friendly and the fern grotto is easily accessible with a short walk on a paved path. Great opportunity to see something up river for those with small children or any mobility limitations.

Our family of six had a great day on the paddle and hike to Secret Falls. Our guide was Harrison and he was amazing. Fun, helpful, and gave us all kinds of cool facts and stories about the flora and fauna and people of the area. He even got a bird to eat a worm out of my daughter’s hand! The falls were huge and beautiful. An absolutely great day!
