Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula

Beautiful views and educational

Reviewed by: Bill

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

Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula

Fine way to kill 2 hours but nothing special

Reviewed by: BobKondz

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

Reviewed by: Love to Travel

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!

Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula

Enjoyable couple of hours.

Reviewed by: Kelman

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.

Since I was pregnant, I had to give up hiking, but I was able to enjoy the great outdoors on this sightseeing flight tour! There were many waterfalls, and I got to see breathtaking views that I've never seen before! Also, since it was whale watching season, we were able to see several whales from the Cessna plane! The family I was with was so excited about the whales that the pilot adjusted our route to chase after them, showing how flexible and accommodating he was in the moment!

妊娠中だったため、ハイキングは断念し、こちらの遊覧飛行ツアーで大自然を楽しむことができました!
滝がたくさんあって、みたことのない絶景をたくさんみることができました!!
また、ホエールウォッチングのシーズンということもあり、セスナ機?の中からも複数のホエールを見ることができました!同乗した家族がホエールに興奮していたので、パイロットが追いかけてくれたりと、その場その場で融通がきくパイロットさんでした!

エアバン遊覧飛行 カウアイ島の絶景を上空から堪能!ワイメア渓谷、ナ・パリ・コースト、ハナペペ渓谷、ジュラシック・パークに登場の滝<英語ガイド/リフエ空港発>

The top experience to have on Kauai Island! カウアイ島で一番やるべき体験!

Reviewed by: HIROCO

When you think of Kauai, you think of the Na Pali Coast. The Na Pali Coast is a breathtaking view that can only be seen by boat, air, or through strenuous trekking. I went trekking, but I wanted to see the whole thing from a boat or by air, so I did some research and ultimately decided that seeing it from above would be best.

Helicopter tours were about twice the price, and boat tours were over 30,000 yen, while this one was in the 20,000 yen range, so I chose this option. Honestly, I felt that 20,000 yen was a great deal for such an amazing experience! I made the right choice!

The stunning views were overwhelming. I was worried about turbulence, but it felt just like being on a regular airplane, and I wasn't scared at all (the pilot was very skilled). Although I'm not fluent in English, the pilot was considerate and chatted with us, guiding us by saying things like, "We're right above here," which made the experience very enjoyable.

We were told to leave our bags in the car, so we weighed ourselves with just our cameras and essentials. There were five of us in total. The other three were all larger individuals, weighing around 70 to 100 kg, and it seemed like the heavier people got the front seats. There were three single seats in a row, and the back had two connected seats, which is where we sat.

In the end, I think the size of the windows and the wide view we had, being away from the wings and wheels, gave us the best angles for photos.

I heard that the mountains look beautiful in the afternoon when the sun is up, so I booked a 2:00 PM flight. The Waimea side was a bit cloudy, but it was absolutely stunning! It was great to see the places I had walked a few days earlier, like the Kalalau Trail and the Kilauea Lighthouse, from above again. I recommend doing this activity later in your trip.

I stayed in Kauai for six days, but the memories from this activity left the strongest impression on me, and I'm really glad I did it. Honestly, if you do this, you might feel satisfied enough not to do anything else. It was truly amazing! I highly recommend it!

カウアイ島といえばナパリ―コースト。ナパリ―コーストは船か飛行か過酷トレッキングでしか見ることができない絶景。トレッキングには行ったけれど、船か飛行で全体を観たいと思い色々調べていて、やっぱり上空からが良さそうだなと思い飛行を選択。
ヘリだと倍ぐらいの料金だったし、船だと3万円以上でこちらは2万円台だったのでこちらにしました。正直2万円台じゃ安いと思うぐらい最高な体験でした!こっちで大正解!

もう感動の絶景の嵐でした。揺れるかなと心配でしたが、普通の飛行機に乗ってるようなレベルでまったく怖くなかったです。(パイロットの運転がうまかった)
英語が堪能ではありませんが、パイロットが気遣って話しかけてくれたり、今ここの上空ですよ~とガイドしてくれたりしてすごく楽しめました。

カメラ以外の荷物は車に置いてね、ということで荷物は車に置いてカメラなど持って行くものを持った状態で体重測定。私の時は全部で5人。私達以外の3人はみんな大きい人で70~100kgぐらいありそうでしたが、体重が重い人ほど前の席という感じでした…1人席が3列あって後ろの席が2席繋がってる感じで私たちはそこでした。
でも結果的に窓の大きさと見える範囲の広さ、翼や車輪から離れているので撮れる画角は一番良かったのではないかと思います。

ナパリ―コーストは太陽が昇っている午後の方が山々の筋が綺麗に見れると聞いて14:00のフライトを予約しました。ワイメア側は少し曇っていたけれどとにかく絶景でした!数日前に歩いたカララウトレイルの場所やキラウエア灯台など、先に行った場所をもう一度上空から見れたのでよかった。旅行後半に行くのをおすすめします。
カウアイ島には6日間滞在しましたが、このアクティビティの思い出の印象が最も強く、本当にやってよかったです。なんならこれさえ押さえれば他いかなくてもいいぐらい満足できます。本当に最高でした!超おすすめします!
