Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula
Great trip up river
Activity Date: 2024/10/07 | Posted on: 2024/10/12

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.

Kauai ATV Waterfall Tour at Kipu Ranch - Off-Road 3-Hour Expedition
Rain made better puddles to splash through!
Activity Date: 2024/10/08 | Posted on: 2024/10/12

So much fun! The views were amazing! My husband was like a kid on Christmas morning driving around in the mud. It down poured right before we left making extra big puddles to splash though. We enjoyed the puddles more than the dust. The guides were fun, engaging, knowledgeable, and made a safe and fun environment. This is very much an off road adventure. If you’re expecting a calm drive through the park, this is not for you.

The tour to the Fern Grotto was great. Really enjoyed the Kauai Coffee Plantation. First time there. Good coffee. Rest of the tour was awesome. Our tour guide was also fantastic. She gave us a lot of great information and history. Definitely a memorable trip.

Beautiful and relaxing. We had family visiting that couldn’t do a big hike, so this was perfect. The singing was such a nice touch.

The reservation process and sightseeing went smoothly, and I had a lot of fun experiencing the cruise. Next time I go to Hawaii, I definitely want to use this service again.

Koloa 8-Line Zipline Adventure - Kauai's Most Adventurous Zip Tour
Great fun, great guides
Activity Date: 2024/09/02 | Posted on: 2024/09/04

We had such a great time. Our guides were so patient and fun. I would say to prepare for a few uphill hikes to next line but guides stayed with us all the time. Their experience, humor and knowledge made the experience a lot of fun. I would definately recommend to the new zipper and to the experienced. Just do it. Ask for Koa and Talen.

We took water but the guides had plenty. The views were amazing.

Fern Grotto
Activity Date: 2024/08/08 | Posted on: 2024/08/31

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.

シダの洞窟 観光遊覧船 ハワイ唯一の航行可能な川を行く!<英語ガイド/半日>
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。

シダの洞窟観光ツアー ワイメア渓谷&ポイプ潮吹岩&オパエカア滝 <英語ガイド>

カウアイ島の魅力を体験できる!
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。

Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula
Relaxing and delightfully humorous
Activity Date: 2024/07/29 | Posted on: 2024/08/02

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.

This was a great outing worth every penny. Definitely wear close toed shoes and bring clothes you are okay with getting red dirt Kauaui stained! An extra towel is a good suggestion as well. Water bottle and big spray if you are going to wear shorts.

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
JD

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.

Family friendly entertainment.
Activity Date: 2024/07/11 | Posted on: 2024/07/15

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.

Kipu Ranch ATV Tour – Scenic Ride Through Jurassic Park Film Locations
Fantastic side by side tour of Kipu Ranch
Activity Date: 2024/07/02 | Posted on: 2024/07/08

Fantastic tour of an amazing place. You see lots of incredible scenery and see where tons of your favorite movies were filmed. The tour is a good balance of learning about the ranch and having a great time driving the side by sides.
They definitely prioritize safety and make sure everyone is doing what they should be in order to have a good time.
You will get dirty from driving on the dusty roads. If you wear contacts be sure to use the goggles they provide to keep the dust out of your eyes.
They also provide a bandana which helps keep the dust our of your mouth/nose.

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。
