野生のイルカウォッチング&ダブルシュノーケリングクルーズ byイルカ大学<ランチ付き/英語ガイド(日本語スタッフ乗船日あり)>
It was disappointing.
期待はずれでした
Activity Date: 2024/12/29 | Posted on: 2025/01/29

I couldn't see any dolphins, whales, or turtles, not even a shadow or a hint of their presence, and I felt no motivation to search for them. The first snorkeling spot had hardly any fish, yet we were made to swim there for a long time. The second snorkeling spot was really great, but I got cold and tired from the first spot, so I ended up spending less time at the second one, which was disappointing. The hot dog for lunch had a sickly red sausage that was surprisingly bad, and I couldn't eat it. It was the worst hot dog I've ever had; I always thought you couldn't make a hot dog taste bad no matter how you prepared it, so I was shocked. There were no pineapples. The boat was simpler than I expected and rocked a lot, making it uncomfortable to ride. I thought the quality for this price was terrible.

イルカもクジラもカメも影も形もみえず、気配さえ感じられず、なんとか探そうという気概も感じられず。一回目のシュノーケルスポットはたいして魚もいないのに長時間泳がされて、2回目のシュノーケルスポットはとてもよかったのに、一回目のシュノーケルスポットで冷えて疲れて2回目の方が短時間になってしまい物足りなかった。ランチのホットドッグが気持ち悪い赤い色のソーセージで、びっくりするほどまずく、食べられなかった。こんなにまずいホットドックはうまれて初めて、ホットドックなんてどう作ってもまずくはならないと思っていたので衝撃だった。パイナップルはなかった。船も思っていたより簡易的で揺れて乗り心地が悪かった。この値段でこの内容はひどすぎると思いました。

Dear Snorkeling Lover,

Thank you very much for participating in the Dolphin Watching & Double Snorkel tour on the Big Island the other day. We sincerely apologize for not meeting your expectations despite your visit.

We have communicated your feedback to the local crew and confirmed the situation on the day of the tour. Regarding the dolphin encounters, unfortunately, there were no dolphins spotted in the bay preferred by them near the harbor, so we moved to the first snorkeling point. Since there were no sightings reported by other tour boats afterward, we proceeded to the next point. While the Big Island is rich in wildlife, we hope you understand that there are times when encounters may not occur.

As for the snorkeling points, we selected locations considering the sea conditions and weather on the day to ensure a safe and enjoyable experience, but we regret that we could not meet your expectations. Additionally, the hot dogs provided for lunch are a local favorite made with paprika coloring, prepared as a Hawaiian local food. Unfortunately, we were unable to provide pineapple as it was sold out that day. We apologize for the crew not being able to adequately explain and apologize regarding lunch during the tour. We believe that if we could have communicated more information during the tour, you would have enjoyed it more.

We apologize again for not being able to alleviate your concerns due to the absence of a Japanese-speaking crew member. If you participate again in the future, please feel free to request Japanese support, and we will arrange for a Japanese crew member.

We will strive to provide a tour that meets your satisfaction once again. Once again, we apologize for not meeting your expectations this time.

シュノーケリング大好き様。 先日は、ハワイ島ドルフィンウォッチング&ダブルシュノーケルのツアーにご参加いただき、誠にありがとうございました。この度は、せっかくお越しいただいたにもかかわらず、ご期待に添えなかったことを心よりお詫び申し上げます。 いただいたご指摘を現地クルーに伝え、当日の状況を確認いたしました。まず、イルカの遭遇に関してですが、ハーバー近くのイルカの好む湾において、当日はイルカが見られず、最初のシュノーケルポイントに移動いたしました。その後も他のツアーボートからの目撃情報がなかったため、次のポイントに移動いたしました。ハワイ島は野生生物が豊富ですが、出会えない場合があることをご理解いただければ幸いです。 シュノーケルポイントについては、当日の海況や天候を考慮し、安全に楽しんでいただける場所を選びましたが、期待に添えなかったことを残念に思います。また、ランチで提供したホットドッグはパプリカの色素を使った地元の人気商品で、ハワイのローカルフードとしてご用意しております。 パイナップルについては、当日売り切れのためご用意できなかったとの事でした。ランチに関してツアー中にクルーがしっかりとご説明とお詫びができず、申し訳ございませんでした。お客様にツアー中に情報をお伝えできれば、より楽しんでいただけたのではと考えております。日本語を話せるクルーが不在であったため、ご不安を解消することができなかったことを重ねてお詫びします。 次回ご参加いただける際には、日本語対応のリクエストをいただければ、日本人クルーの調整を行いますので、ぜひお気軽にお知らせください。お客様に再度ご満足いただけるツアーを提供できるよう、努めてまいります。 改めて、この度はご期待に添えなかったことをお詫び申し上げます。

I would not change one thing about this tour. It exceeded our expectations. the communication before the experience was excellent. Jason was an exceptional guide - so attentive! He is an expert in astronomy and Hawaiian history which we greatly enjoyed. He had a great telescope and a cool machine that takes pictures of celestial objects in the sky that he EVEN EMAILED TO US LATER! Just wow! The chicken stew was delicious too! An overall amazing, once in a lifetime experience. Thank you! Rita and Bob

I was able to see manta rays up close.
マンタを近距離で観れました。
Activity Date: 2024/10/21 | Posted on: 2025/01/20

I participated in an English-only tour because the Japanese-speaking reservations were fully booked. The experience itself was impressive, as there are many similar tours in the area, and manta rays regularly approached us. The staff was also very accommodating. However, the time spent floating in the sea was quite long, and it can be tough if you don't have the stamina to hold onto the float. My wife had to retire midway. There were no unnecessary services, so it was relatively inexpensive, and it might be a good option for those looking for this kind of experience.

日本語対応の予約がいっぱいだっだので、英語オンリーのツアーに参加しました。
体験自体は周辺にたくさんの同じようなツアーがあるため、マンタが定期的に近づいてきますので迫力がありました。スタッフも対応が良かったです。
ただ、結構海に浮かんでいる時間が長いのと、浮き輪に捕まっている体力が無いと厳しいです。嫁さんは途中でリタイヤしました。

I went to the Onizuka Visitor Center, but the tour was canceled due to strong winds. However, I learned that I could reschedule for a fee, so I tried again the next day‼️ I was able to reach the summit safely. This was my fourth time, and I think the reassurance of having a reliable guide each time is very important. I plan to bring different guests next time and will definitely ask for your services again. Thank you!

I went on the stargazing tour for the second time this time. It was a full moon, so there were slightly fewer visible stars than last time, but I was overwhelmed by the beautiful night sky. Despite the cold, the hot cocoa they prepared was exceptionally delicious. The sandwiches provided were also tasty. Thank you very much.

This is my third manta tour, and each one has been different. This time, I felt the most at ease. Having support from Japanese staff was really helpful. The moment the manta appeared was truly breathtaking. However, it was quite cold during this season, and the return trip to the port was chilly, so those planning to go should prepare accordingly.

Brett was an excellent tour guide. Funny engaging and informative. It is a long day as the island is rather large. Greenwell Farms (coffee farm) was our first stop. Excellent coffee! Brett explained the growing and harvesting process, followed by tasting and souvenir purchases. Then on to the Punalu'u sweetbread bakery for treats. I lived the Lilikoi flavored pastry. Nice gift shop also. Next stop was Punalu'u black sand beach with a bonus sleeping turtle. Quick provided tasty lunch at a shady state park. Next into Volcano National Park. Brett has fantastic volcano pics. Kilauea was steeming and erupted hours later. Traveled down a large lava tube, very cool. Huge old lava fields. Next on to Rainbow falls and majestic Akaka falls on the East side of the island. On the North end, we visited Waipi'o lookout for sunset. It was along day, but excellent. Strongly recommend. Brett made the trip very enjoyable.

マウナケア山頂夕陽と星空観測ツアー ガイド撮影の一眼カメラ写真を無料ご提供!<夕食付き/英語ガイド>by マサシネイチャースクール
The sunset and starry sky at the summit of Mauna Kea were amazing! The guide was also wonderful. However, there was a bit of a disappointment...
マウナケア山頂の夕日と星空、最高でした!ガイドさんもすばらしかった。ですが一部残念な・・・
Activity Date: 2025/01/03 | Posted on: 2025/01/10

I saw many reviews mentioning that the weather is often bad in winter, but on January 3rd, when I participated, it was clear and we were able to reach the summit without any issues. The sunset seemed to fall into the clouds, but it was incredibly beautiful. Our guide, Sho-you, was entertaining during the journey and very considerate, making the travel time enjoyable.

As for stargazing, I thought it might be hard to see because the moon was bright, but we were able to see various constellations, and the moon, Saturn, and Jupiter looked stunning through the telescope. The guide's explanations about the night sky were very interesting for us!

The BLT sandwich we had at the summit was seasoned perfectly and tasted better than I had imagined (laughs). I haven't received the photos yet, but I'm sure they captured some wonderful moments.

The tour itself and the guide were fantastic, and we had a great time, but there was a slight disappointment. I was a bit late for the scheduled meeting time of 14:30, so I called to inform them, but the person who answered the phone (not the guide) was quite rude. In the end, we arrived almost on time, but when we got to the meeting place, the tour vehicle was not there... After several calls, it turned out that the meeting time we were given was incorrect, and it was actually 15:00. They did apologize, but I wondered if they had noticed it when I first called, it might have prevented any unpleasant feelings (the notification about the change in meeting time came later...).

Also, I had signed up for the English tour, but when we joined on the day, it turned out to be a Japanese tour. Since three out of four participants were Japanese, we ended up enjoying it, but I think it would have been better if we had been informed in advance about any changes.

So, while the tour itself deserves five stars, overall, I would rate it four stars.

冬は天気が悪い日が多いという口コミもたくさんみかけましたが、参加した1月3日は快晴で、問題なく山頂まで行けました。
夕日は雲の中に落ちる感じではありましたが、すごくきれいに見えました。
ガイドの翔陽さんの道中のトークもおもしろく、気配りも素敵な感じで、移動時間も楽しい時間を過ごせました。
星空観測も、月が明るい日だったので見えづらいかなと思いましたが星座もいろいろ見ることができ、望遠鏡で見た月、土星、木星もとてもきれいでした。ガイドさんの星空解説も、我々にとってはすごくおもしろかったです!
そして山頂でいただいたBLTサンド、塩がきいてて想像してたよりおいしかった(笑)
写真はまだいただいていないですが、きっと素敵なのを撮っていただけているはず。

ツアー自体もガイドさんもすばらしく、良い時間を過ごせたんですが、少しだけ残念だったことが。
通知されていた集合時間14:30に少しだけ遅れそうだったので電話連絡をしたのですが、電話口に出た方(ガイドさんとは別の方)の態度が大変横柄でした。結局ほぼ遅れずに到着できたんですが、待ち合わせの場所に行ってもツアーの車はおらず・・・何度か電話連絡して、結局我々に伝えられていた集合時間がまちがっていて、本当は15時だったことが判明。一応謝ってはいただいたんですが、最初に電話した時に気づいていただければいやな気持にならずに済んだのかな、と思いました(集合時間変更の通知は後から来ました・・・)。
また、英語ツアーで申し込んでいたんですが当日合流したら日本語のツアーになっていました。4人中3人は日本人だったので結果的には楽しめたんですが、変更がある場合は事前にご連絡いただけると良かったかなと思います。
ということで、ツアー自体は☆5つだったんですが、総合して☆4つにさせてもらいました。

Activity Date: 2024/08/12 | Posted on: 2025/01/05

I found information online and on YouTube that some people drive to the summit of Mauna Kea by rental car, so I was hesitant about whether to join a tour, but it was definitely the right choice to participate.

First of all, even with a navigation system, it seems easy to get lost as it gets dark, and returning at midnight while tired from the trip makes it even more challenging. The parking space at the summit is also limited, so I believe joining a tour is the best option. I actually wanted to choose a Japanese tour, but it was fully booked, so I joined the English tour instead. However, when we observed the stars through the telescope, we were at the same location as the Japanese tour by VELTRA, so I was able to listen to the explanations from their tour guide.

The tour I participated in had three Americans and seven Japanese participants. On the way back, it seemed that the local Japanese guide had selected the music, as Japanese hit songs related to the sky (like Ayaka's "Mikazuki" and Checkers' "Hoshikuzu no Stage") were playing, and I secretly enjoyed it while everyone else was sleeping.

ネットやYouTubeでマウナケア山頂までレンタカーで行く方もいらっしゃるとの情報があったので、ツアーに参加するか迷いましたが、参加して正解でした。
まず、山頂まではナビがあったとしても暗くなってくると迷いそうですし、何しろ帰りは真夜中で旅の疲れもあり眠くなります・・・。頂上の駐車スペースも狭く、個人で行くよりツアー参加がベストな選択と思いました。本当は日本語ツアーを選択したかったのですが、定員オーバーで英語ツアーに参加しました。ただ、天体望遠鏡で星を観察する時は同じVELTRAさんの日本語ツアーと同じ場所だったのでそちらのツアーガイドさんの説明を聞くことができました。私が参加したツアーはアメリカ人3人日本人7人でした。帰りの車内ではおそらく現地の日本人ガイドさんが選曲されたのか?空にまつわる邦楽ヒットソング(絢香の三日月やチェッカーズの星屑のステージなどなど)が流れていて、みんなが寝ている間密かに楽しんでいました。

Activity Date: 2024/12/26 | Posted on: 2025/01/02

Right after we set off, we spotted a pod of dolphins near the exit from the port. They even showed us some jumps. The snorkeling point seemed to be beginner-friendly since there were children, but the waves were quite rough, and there were only a few types of fish, so it wasn't a very impressive experience. As a result, some participants got seasick, and although it was a tour that included lunch, when I mentioned that I couldn't eat, nothing was provided, and the tour ended. I wasn't able to ask because my English isn't very good, but I wish they had at least asked if I wanted to take something back.

出発してすぐ、港からの出口付近にイルカの群れを発見。ジャンプも見せてくれました。シュノーケルは子供も居たので初心者向けのポイントだった様ですが、結構波が荒く、魚も数種類で感動体験とはいきませんでした。結果参加者は船酔いしてしまい、昼食付きのツアーでしたが今は食べられなそうと言ったら何も提供されないままツアー終了。英語が不慣れな事もあり聞けませんでしたが、せめて持ち帰るか?など聞いて欲しかったです。

Tips and suggestions

I wouldn't particularly recommend snorkeling. You might enjoy a dolphin and whale watching cruise more.

シュノーケルは余りオススメ出来ない。イルカ、クジラのウォッチングクルーズの方が楽しめるかもしれません。

Aloha, Yuzu. Thank you for participating in the Dolphin Watch & Double Snorkel by Dolphin University on the Big Island. We were glad to encounter a pod of dolphins and see them jump! We also appreciate you sharing your dolphin photos. However, we apologize that the snorkeling did not meet your expectations due to rough sea conditions. We will share your feedback regarding lunch with our staff to improve our services in the future. We sincerely look forward to your next participation. Mahalo nui and a hui hou!

アロハ、Yuzuさま。ハワイ島ドルフィンウォッチ&ダブルシュノーケルbyイルカ大学に参加していただき、ありがとうございました。イルカの群れに遭遇しジャンプを見せてくれて良かったです!! またイルカの写真を共有していただき感謝いたします。しかしながら、シュノーケルは海が荒れていたようであり、Yuzuさまの期待に応えることができず申し訳ございませんでした。ランチに関してはYuzuさまのご指摘をスタッフと共有し、今後のサービス向上に繋げさせていただきたいと存じます。Yuzuさまのまたのご参加を心よりお待ちしております。Mahalo nui and a hui hou!

We had a wonderful time with James! He explained things thoroughly! He did not try to rush us in any way, and took lots of nice pictures! I would highly recommend taking stargazing tour with Hawaiian eyes!

Mauna Kea Summit Sunset & Stargazing Tour with Meal, Transportation & Guide
Breathtaking sunset and star gaze!
Activity Date: 2024/12/24 | Posted on: 2024/12/26

We took the tour on 12/24/2024. It was a full car but very friendly and nice guests together! The eruption was very stunning and the star gaze - wow!
Our guide James is very helpful patient and good at photo shooting as well. He can also speak a little Japanese. Parka jackets saved our lives for sure.
The overall trip experience was excellent. The sandwich was surprisingly good as well.

Awesome experience
Activity Date: 2024/12/21 | Posted on: 2024/12/23

Host was really good, very polite and understanding.

The sandwiches were good, and the hot coco while stargazing, was delicious cherry on top of the whole experience.

The only issue I would complain about is the vehicle, because the space was really cramped up and it was a struggle to get in and out of the vehicle. Many from the back of the vehicle complained about the air conditioning, but I didn’t feel any discomfort, even though I was in the last row

The summit of Mauna Kea is wonderful.
マウナケアー山頂は素晴らしい
Activity Date: 2024/09/17 | Posted on: 2024/12/23

The summit of Mauna Kea at 4,000 meters is absolutely amazing. Aside from the fact that the oxygen is 40% thinner than at sea level, it’s an incredible experience. This is my second time reaching the summit, and I over-prepared, thinking it would be just as cold as last time. However, I realized there is a significant difference between the January ascent and the September ascent, almost like winter and summer. I was lacking information, but I still had a wonderful experience.

なんと言っても、マウナケアー山頂4000m級の登頂は最高です。酸素が下界より40%も薄いことを除けば、すごい体験です。今回で2回目の登頂になりますが、準備をし過ぎて、寒い寒いことだけが、前回の登頂で、今回も絶対寒いと思い、準備万端に出向きましたが、全回の1月登頂と、今回の9月登頂では、冬と夏ぐらいの違いがあるといううことがわかり、情報不足でした。でも素晴らしい体験ができました。

Great Memories!!!
Activity Date: 2024/11/30 | Posted on: 2024/12/21

My husband and I had a great time in the tour. We were picked up on time and the guide made the trip to the summit entertaining and we learned many different things about Hawaii during that time.
The sunset at the summit is breathtaking and our guide was prepared to take pictures that he later shared with all of us!
It got cold after the sunset…. so be ready. The hot chocolate while stargazing was a very nice addition!

It was a tour beyond my imagination.
想像以上のツアーでした
Activity Date: 2024/12/16 | Posted on: 2024/12/18

The stargazing tour allowed me to see so many stars with the naked eye that it felt like stardust was falling from the sky. The quality was extremely high, and I was very satisfied. (The photo was taken with my smartphone, so I could see about ten times more stars with my eyes.)

Additionally, the guide's explanations during the journey were clear and entertaining, providing quality entertainment throughout the day. (I was lucky that the bus I happened to be on was exclusively for Japanese guests, so I was able to receive the English tour in Japanese.)

Next time, I would love to join a tour of the recommended spots by the guide.

If I have the opportunity to come back to the Big Island, I would like to participate in the tour again. Thank you very much.

星空ツアーは星屑が空から降ってくるように感じるほどたくさんの星を肉眼で見ることができ、非常にクオリティが高く大満足でした。(写真はスマホで撮ったものなので肉眼では10倍くらい星が見えています。)

また、道中のガイドさんの案内がわかりやすく、かつ面白く1日を通して良質なエンターテイメントを提供していただきました。
(たまたま私の乗車したバスが日本人客のみのバスだったため本来英語のツアーを日本語で対応いただけたのはラッキーでした)

次回はぜひガイドのお兄さんのオススメスポットツアーがあれば参加したいくらいです。笑

またハワイ島に来る機会があればツアーに参加させていただきたいです。
ありがとうございました。

Tips and suggestions

The summit in December was really cold, so it's good to have a neck warmer and Heattech.

12月の山頂は本当に寒かったのでネックウォーマーやヒートテックなどあるといいです。

I was a bit disappointed because I thought more manta rays would gather in the light, but there were only a few. Next time, I want to see dolphins.

マンタが、もっと光に集まってくるかと思い数匹だったのでちょっとガッカリでした。
じかいは、イルカちゃんをみたいです。

Aloha! Leo. Thank you for participating in Manta University. I apologize for the delay in my response since the day of the event. I’m sorry that there were fewer mantas than expected on the tour day, and I regret that it did not meet your expectations. If you have the opportunity to visit Hawaii again, we would be delighted if you could join us for Dolphin University on the Big Island or Oahu to see wild dolphins. All of our crew sincerely looks forward to your participation again. Mahalo nui and a hui hou!

アロハ! レオさま。マンタ大学に参加していただき、ありがとうございました。参加日から時間が経っての返信に関してお詫び申しあげます。ツアー当日はレオさまの期待を下回る頭数のマンタしか集まらず残念な思いをさせてしまい申し訳ございませんでした。またハワイにいらっしゃる機会には、ぜひ、野生のイルカを見にハワイ島もしくはオアフ島のイルカ大学へ参加していただけたら幸いです。クルー一同、またのご参加を心よりお待ちしております。Mahalo nui and a hui hou!
