Wailua River Kayak & Secret Falls Hike - Guided Kauai Adventure
Fantastic, Educational Adventure
Posted on: 2012/06/29

Kayak Kauai Outbound makes this trip an experience not to be missed. Kelly was an extraordinary guide, enthusiastically sharing his knowledge and passion for the land, the local history and ancient culture. He went out of his way to make the hike interactive and interesting. He has a real gift for this. The operation, overall, is very laid back. You're made to feel comfortable with every aspect of the tour. We highly recommend Kayak Kauai Outbound and will surely be returning on our next visit to the island!

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>
Cave of the Ferns
シダの洞窟
Posted on: 2012/05/02

I participated in an activity on the afternoon of the day I flew from Japan to Hawaii, and then to Kauai. Since I was dealing with jet lag, a calm activity like this was just right for our first day in Hawaii with the kids.

It might have been nice to combine this with the "Hawaiian Traditional Feast Luau and Sacred Ceremony Imu! Smith Tropical Paradise Luau," which is located on the same grounds. Our family watched the luau on the last day in Kauai, but among those on the same boat, quite a few were planning to have dinner and see the luau show after this boat ride.

The Fern Grotto was beautiful, but everyone in the family got bitten by mosquitoes. I recommend applying insect repellent before participating.

日本からハワイへ、さらにカウアイ島へ飛んできたその日の午後に参加しました。時差ぼけの状態なので子どもも連れてのハワイ初日はこのぐらいの穏やかなアクティビティがちょうどよかったです。

同じ敷地内にある、「ハワイ伝統饗宴ルアウと神聖な儀式イム!スミス・トロピカル・パラダイス・ルアウ」と組み合わせてもよかったかもしれません。私たち家族はカウアイ島最終日にルアウを分けて見ましたが、同じ船に乗っている人の中では、この船の後に夕食とルアウのショーを見る予定である人が結構いました。

シダの洞窟はきれいでしたが、家族みんな蚊に刺されました。虫除けを塗っての参加をお奨めします。

カウアイ島 ワイルア川カヤック&熱帯雨林ハイキング <英語ガイド/昼食付き>
It was fun!!
楽しかった!!
Posted on: 2011/11/18

It was my first time kayaking, and it was a lot of fun. We sat in a two-person boat, going upstream for about an hour. Then we walked through the jungle, during which the guide taught us various things. We had lunch in front of a waterfall and then returned to where we started by kayak.

I think it's fine to wear a swimsuit underneath with a shirt and shorts. I would recommend avoiding athletic shoes or flip-flops, as the paths in the jungle are quite muddy and your feet will get messy. We rented sports sandals from the tour company for a fee.

Of course, since the guide speaks only English, I think it would be more enjoyable if you understand English.

カヤックは初めてでしたが、とても楽しかったです。
2人乗りのボートに前後で座って、1時間弱ぐらい上流へ行きます。そのごジャングルの中を歩きながら進みますが、その途中でガイドさんが色々なことを教えてくれます。滝の前で昼食を食べその後カヤックで出発したところに戻ります。
服装は水着を中にきてシャツと短パンでOKだと思います。
運動靴やビーチサンダルは止めておいたほうが良いと思います。ジャングルの中はかなりの泥道で足がぐちゃぐちゃになります。私たちは、お金を払ってツアー会社からスポーツサンダルを借りました。
もちろんガイドさんは全て英語の為英語がわかるほうが楽しめると思います。

Excellent activity
Posted on: 2011/08/03

We enjoyed the kayaking and hiking both. The Scared Falls were well worth the hike. I recommend good water shoes for the hike. I did it in flip flops and it was a bit tricky! Jesse was our guide and he was great, very energetic and knowledgable.

very enjoyable
Posted on: 2011/02/15

We totally enjoyed the river cruise and the fern grotto. We were a little disappointed we could not actually go into the grotto but totally understand. It will be good to come back and see it again after a few years and some more fern growth.

The wailua river cruise is very unique, we saw a lot of Kauai we didnt know was there, and learned a lot from our guide. The pace of the tour is slow and relaxed.

Smith’s Fern Grotto River Cruise with Live Hawaiian Music & Hula
Even less than I expected
Posted on: 2011/01/14

The staff was very nice and the boat ride was relaxing but the Fern Grotto itself was less than I expected, and I wasn't expecting much.
You don't go inside the cave. You just look at it from a distance.
You can see ferns growing from the face of a rock cliff where the cave is located. You view it from a platform where weddings are performed these days. You can't go inside to see the area where 100 people can gather.

Perfect for first timers!
Posted on: 2010/08/23

Our first time to Kauai and we decided to try the Wailua River Cruise to Fern Grotto and we absolutely loved it! it was kinda slow but very relaxing, and such beauty surrounding you how could you not like it..
I know its got some bad reviews and I cant understand why, if you appreciate the beauty of Kauai then you will love this short and sweet experience and you can get some really great pictures too.

The Smith family embraces you with their Hawaiian charm as soon as you meet them! The river trip to the Fern Grotto was a beautiful experience. We were celebrating our 30th wedding anniversary so when the singers sang the Hawaiian Wedding Song it was very special! The Hula dancer on-board was not only beautiful, but very talented as well. Even my husband participated in the learning of the Hula dance - much to my delight! I would do this trip again if ever given the chance. Truly memorable!

The boat is kind of boring, but also very scenic. The grotto does make it worthwhile. I suggest doing the Smiths luau right after this, they are right together, so why not!
