Surrounded by forests, I was able to experience things that I normally wouldn't. I also got to hear local people's songs, which allowed me to feel the essence of Hawaii.

Okay trip
Activity Date: 2024/12/06 | Posted on: 2024/12/08

This trip was fine, and thankfully inexpensive. The entertainers seemed to not want to be there. They went through the motions, but weren’t excited. The fern grotto was cool to see, and it was neat to go through a jungle.

We really enjoyed the trip on the river with the explanation for what we were seeing and the explanation of the grotto. The Captain and Crew were friendly and accommodated our special needs, my aunt with a walker. This is a tour I highly recommend for anyone visiting Kauai.

Guides were entertaining, knowledgeable, and funny! They shared lots of information about the land, and culture. The boat ride was smooth and relaxing up river, and fun coming back down river. The Grotto is breathtaking! Quick easy hike to and from the grotto.

This was a great/relaxing experience. Nice cruise up and down the river, good historical information, and easy walk to the grotto. Well worth the time. If you have any problems walking then do not try this. The walk is short but why pay just for a boat ride? This was worth MY time and I would do it again.

The Cedar Cave, wonderful hula dance.
シダの洞窟、素晴らしいフラダンス
Activity Date: 2024/08/14 | Posted on: 2024/08/16

On the last day of my stay in Kauai, I participated in this experience. From the welcome music upon boarding to the entertaining talks, the journey to the fern cave, the beauty of the cave, the songs and hula dances in front of the cave, and the music, singing, and hula dancing on the return boat, it was all very rich. The final solo by the female captain just before docking, with the waves, wind, flowers, and swaying leaves... the hula dance that conveyed the beauty of nature was truly breathtaking.

カウアイ滞在最終日に参加しました。はじめから終わりまで、入船する際のウェルカムミュージック、楽しませてくれるトークから、シダの洞窟への道のり、洞窟の美しさ、洞窟前の歌とフラダンス、帰りの船の中での音楽、歌、フラダンスと盛り沢山で、とくに女性キャプテンによる寄港直前の最後のソロの波、風、花、葉の揺れ...自然の美しさを感じさせるフラダンスは圧巻でした。

Activity Date: 2024/08/05 | Posted on: 2024/08/12

I was able to fully enjoy the nature-rich Kauai Island. I truly had a wonderful experience.

Of course, I got to see the Fern Grotto and Waimea Canyon, known as the Grand Canyon of the Pacific, as well as the valleys and waterfalls visible along the way. The lunch sandwiches were delicious too! In addition to the beautiful natural scenery, we also stopped by a Kauai coffee shop where I could enjoy some very drinkable coffee. The driver and guide were friendly and skilled at driving. I would like to sign up for a tour with Polynesian Adventure again on my future travels.

自然豊かなカウアイ島を満喫することができました。本当に良い想いをさせてもらいました。

シダの洞窟や太平洋のグランド・キャニオンと呼ばれるワイメア渓谷はもちろん、道中にて見える渓谷や滝なども見ることができます。ランチのサンドイッチも美味しかったです!また、自然豊かな場所に加えカウアイコーヒーショップに寄ることができます。とても飲みやすいコーヒーを飲むこともできます。ドライバー兼ガイドの方も気さくですし、運転も上手です。今後も旅行の際にはPolynesian Adventureさんのツアーに申し込みたいと思いました。

Relaxing and delightfully humorous

This river boat tour was very relaxing and enjoyable. Our guides were talented, insightful, and had a great sense of humor. The fern grotto was a lovely stroll. The live entertainment set the mood for the rest of our trip. If you are weary about going on this river boat, don’t be, it is a sweet smooth ride. We highly recommend doing this tour while visiting Kauai.

Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula
Budget friendly getaway from the beach (wheelchair/kid friendly)
Activity Date: 2024/07/15 | Posted on: 2024/07/18

Large boat brings you about 30 mins down river with a tour guide speaking overhead. Our tour guide was very funny and was probably my favorite part of this activity. You’ll disembark at an area with walkways/bathroom through a lush rainforest that eventually ends at an area with a large cliff/cave. APPLY BUG SPRAY! There are lots of mosquitoes in this area.
Here you’ll get a short history of the location as well as some music/hula dancing.
You’ll head back to boat and return with more traditional ukulele music/hula dancing.
Wasn’t a fan of the music myself, but enjoyed the trip overall.
If you aren’t able to do a strenuous hike, wheelchair bound, or have small children this activity is short enough to get a taste of the scenery without the hassle of a rough walking trail.

Nice relaxing ride down the Wailua River with a short, easy walk to the Grotto. Learning about the history of the boats and the area was very special, as well as having the Hawaiian music and dancing on the boat. The pilot was witty and made a couple of cute jokes. Definitely recommend for families or as an alternative for more strenous activities, or just as a nice cool break from the hot days.

At the cedar cave with my family.
シダの洞窟に家族で
Activity Date: 2024/01/01 | Posted on: 2024/07/01

We participated as a family of four (two adults and two elementary school children). We took a boat to the Fern Cave. During the round trip on the boat, there were explanations, songs, and dances about the Fern Cave, which were enjoyable. However, everything was in English, so there were parts we didn't understand. Visiting the Fern Cave on January 1st made us feel a sense of sacredness.

家族4人(夫婦と小学生2人)で参加しました。
シダの洞窟までは船で行きます。往復の船の中では、シダの洞窟の説明や歌、ダンスなどがあり楽しめます。ただし、すべて英語なので、わからないところもありました。
1月1日にシダの洞窟に行けて、神聖な気持ちになりました。

During the round-trip cruise, we enjoyed the captain's guidance, Hawaiian music, and dance. Upon arrival, the sacred scenery brought peace to my heart. The announcements were all in English, but I could understand them well enough to enjoy the experience. After arriving on Kauai, I booked the tour online for a day that looked like good weather. It's a tour with great cost performance. I highly recommend it.

往復のクルージング中は船長の案内やハワイアンミュージック、ダンスで盛り上がりました。到着後は神聖な景色に心が安らぎます。案内は全て英語ですが、なんとなく分かるので楽しめましたよ。カウアイ島着いてから天気の良さそうな日にネットで申し込みました。コストパフォーマンスが良いツアーです。お奨めです。

It was a tour where you could enjoy Hawaiian music on a boat.
ボートでハワイアンミュージックも楽しめるツアーでした
Activity Date: 2024/05/03 | Posted on: 2024/05/11

Check-in information:
Please note that the map guidance is not accurate. You can check in by providing your name at the ticket booth near the Wailua River boat launch. By the way, I was able to ride the bicycle I borrowed from the hotel and park it there.

About the tour:
On the boat, there was a sightseeing guide (historical explanation), and we all stood up and danced to Hawaiian music, creating a cheerful atmosphere. It's enjoyable even if you participate alone. I don't know what it was like when we could enter the fern cave, so compared to that, the fern volume seems a bit lacking, but it was still a good tour.

チェックインについて
地図の案内とずれているので注意です。ワイルアリバーボート乗り場のチケット売り場のところで名前を伝えれば受付できます。ちなみに、ホテルで借りた自転車でいき、停めることができました。

ツアーについて
ボートでは観光案内(歴史説明)もあったり、ハワイアンミュージックでみんなで立ち上がって踊ったり、陽気な雰囲気で過ごせました。1人参加でも楽しめます。シダの洞窟の中に入れた当時を知らないので、それに比較するとシダボリュームが貧弱のようですが、それでも良いツアーでした。
