At an elevation of 4,205 meters, I was drawn to the starry sky closest to space and participated in the tour. The guide was fluent in Japanese, and we were able to enjoy the tour from start to finish. We were able to view both the sunset and the starry sky in the best conditions, and I felt grateful to have come to the Big Island. The tour offered a wonderful experience that I might never have again, such as being able to reach 4,205 meters by car and gaze at the starry sky closest to space. I highly recommend this plan to anyone considering a visit to the Big Island.

標高4205メートル、宇宙に一番近い星空に惹かれ、ツアーに参加させて頂きました。ガイドさんも日本語が堪能な方で、終始楽しくツアーを終えることもでき、夕日も星空もベストなコンディションで鑑賞することができ、ハワイ島へ来て良かったと思いました。また車で4205メートル地点に行けることや宇宙に一番近い星空を眺めることなど、人生で二度とできないかもしれない素晴らしい体験ができるツアーでしたので、ハワイ島観光を検討されている方に是非お勧めしたいプランです。

The best starry sky of my life.
人生最高の星空
Activity Date: 2025/08/16 | Posted on: 2025/08/17

The tour on the 16th was guided by Mr. Sho Yo. This was my third time at Mauna Kea, but this was the best experience I've had so far. I think I've heard explanations many times before, but this time they were very easy to understand. The guide provided accurate information at great points. I listened in both English and Japanese, which was also good. I saw the most beautiful starry sky for the first time in my life, and I clearly recognized the Milky Way for the first time. The constellations and star names that I've heard many times finally sank into my head and heart!

16日のツアーです。ガイドさんは、翔洋さんでした。
マウナケア、3度目ですが、今回が、これまでで最高の体験でした。これまで何度も説明聞いていたとは思うのですが、説明がとてもわかりやすかった。またいいポイントで的確に教えてくれる。英語と日本語、両方で聞いたので、それも良かった。星は人生で初めて、あんな綺麗なほしぞらをみましたし、天の川を初めてハッキリと認識しました。星座、星の名前、何度も聞いているものが初めて頭、心に入りました!

It was the best experience, thanks to James, our guide, who was very attentive, and the favorable weather. The route from the Onizuka Center to the summit was quite off-road, so it was definitely the right decision to join the tour. The outerwear we were provided was very warm. The sandwiches and cocoa for dinner were also delicious.

Activity Date: 2025/08/14 | Posted on: 2025/08/15

We participated as a family of four. On the day of the event, we were worried because the forecast predicted cloudy weather, but just as the guide explained, the clouds cleared, and we were able to see a magical sunset. The stargazing was breathtaking, and it was a good time of year, so we were able to see many shooting stars. The guide's explanations about the stars were also very good. They served us warm cocoa, which warmed us up and was delicious. I recommend that when you visit the Big Island, you take the time to see the starlit sky and the sunset.

家族4人で参加しました。
当日は曇りの予報で心配していましたが、ガイドさんの説明のとおり雲がはけ、幻想的なサンセットを見ることができました。星空観測は圧巻で、時期も良かったそうで流れ星も多数見ることができました。ガイドさんの星の説明もとても良かったです。温かいココアを出していただき身体も温まり、美味しかったです。

I participated in the same tour 10 years ago, signing up without thinking, just wanting to see the starry sky. The weather was perfect, and I was able to take beautiful sunset photos. However, I realized for the first time how bright a full moon can be. It was so bright that it cast shadows. This time, I researched the moon phases and planned a comeback after 10 years. Miraculously, the clouds cleared, and I enjoyed a stunning night sky. I was able to see the Milky Way, shooting stars, and fully enjoy the starry sky. The BLT sandwich and cocoa provided by the tour were delicious, especially in the cold. Thank you, guide Shoyou.

10年前に同じツアーに参加しましたが、何も考えずに星空が見たいと申し込み、天気は最高でサンセットも綺麗な写真が撮れた。ところが、肝心の星空は、、、満月の月があんなに明るいなんて初めて知りました。月明かりで影ができるほど。今回は月の満ち欠けも調べて10年ぶりのリベンジ。奇跡的に雲もなくなり、満点の夜空を満喫。天の川に流れ星とフルコースで星空を楽しめました。ツアーで用意してくれたBLTサンドと寒い中でのココアは美味しかった。ガイドのショウヨウさん、ありがとうございました。

They guided us to several observatories, and the sunset viewed from the summit was very beautiful. We did some stargazing a little below the summit. Unfortunately, it was a full moon, but we were still able to see many stars. They explained the stars and showed us the moon through a small telescope, making it a very good experience.

Activity Date: 2025/08/06 | Posted on: 2025/08/15

It was a valuable experience, but it felt too commercialized, and I wasn't moved by it. There were about 40 participants in the tour I joined, and there were many other boats from different companies in the area. Right below us, there was also a group diving. Due to the timing, we could definitely see a lot of manta rays. They appeared one after another and even spun right in front of us.

貴重な体験でしたが、あまりにも商業的な感じがして、感動はありませんでした。私の参加したツアーの参加者は40人くらいで、現地には他社の船もいっぱいでした。私たちの真下では、ダイビングしているグループもいました。時期的なこともあって、確かにマンタはたくさん見ることができます。次から次へと現れて、目の前で回転してくれたりもしました。

The scenery is breathtaking, and you can easily reach mountains over 4,000 meters. They provide excellent cold weather gear. The guide's attention to detail was wonderful! Although the guide was foreign (English-speaking), it wasn't a problem as long as you could understand a little. Instructions were given in Japanese at key points.

Please experience the scenery and highlights for yourself. An impressive landscape and a grand panorama await you. It probably won't come across in photos...

It was almost a full moon, but if there's a next time, I'd like to aim for a new moon!

圧巻の風景で、気軽に4000m以上の山に到達できます。
寒さ対策もバッチリして貰えますし。ガイドさんの気配りが素晴らしかったです!
外国人ガイド(英語)でしたが、少しのヒアリングが出来れば問題無かったです。
要所では日本語で指示して貰えます。

風景や見どころは行ってみて体験してみてください。圧巻の風景と大パノラマが広がります。
写真ではきっと伝わらないでしょう。。。

ほぼ満月の時でしたが、次回あるなら、新月の時を狙いたいです!

They provided courteous service.
丁寧に対応してくださいました
Activity Date: 2025/08/09 | Posted on: 2025/08/14

I was worried because I hadn't received a confirmation email for the tour (I contacted VELTRA and they followed up for me).

However, on the day of the tour, I was about 20 minutes late for the meeting time, but they kindly said, "It's okay!" and allowed me to join (I did call ahead). After boarding the boat, they provided a briefing on the sizes of the snorkeling equipment and how to use the camera correctly. They also prepared Japanese instructions, so even though my conversational skills are very basic, I felt comfortable participating.

The waves felt a bit high, but they designated a snorkeling area, and during the snorkeling, staff members were patrolling on a paddleboard, which showed they were very attentive to safety. It seemed like the tour was fully booked, but there were plenty of floatation devices and life jackets available. Although I could see to the bottom, there weren't many fish, likely due to the high waves, but we still had a great time as a family!

Since it was a large boat, I didn't experience seasickness, and the cruising to and from was enjoyable. I felt from our conversation that they have a great respect and consideration for the ocean. After getting wet, the cruising felt cold, so I think it would be good to have a separate towel that doesn't get wet. I found the free water a bit difficult to drink. Also, since there were no warm drinks available, if you're worried about getting cold, it's better to bring your own.

The staff were kind, and they were accommodating even with my limited English skills. It was fun!

ツアーまでは、予約確定のメールが来ていなかったりで心配でした(ベルトラさんに問い合わせして、フォローいただきました)。

が、ツアー当日、集合時間から20分ほど遅れてしまったのですが、『大丈夫よ!』と言ってくださり心よく参加させてくださいました(事前に電話はいれました)。
船に乗った後は、シュノーケルの物のサイズや、正しい動画の使い方をレクチャーしてくれます。日本語の案内も用意してくれるので、すごく簡単な会話しかできない私でも安心して参加できました。

波は少し高いように感じましたが、シュノーケルエリアも指定してくださり、シュノーケリング中も職員の方がサップに乗って巡回されていたりして、安全にはすごく気を配っているのが伝わりました。
ツアーは満席だったように思いますが、浮き輪や救命胴衣も十分に用意されてました。
波が高かったからか、底まで見渡せたもののお魚はそんなに多くみられませんでしたが、それでも充分家族で楽しめました!

大きなボートだったので、船酔いもなく、行き帰りのクルージング楽しかったです。
海への敬意や配慮もすごくされているのだとお話しから感じました。
濡れた後のクルージングは寒く感じるので、羽織るタオルは濡れてしまうのと別にあると良いと思いました。
フリーで用意されているお水が少し飲みにくいと感じました。あと、温かい飲み物はないので、冷えてしまうことが心配なら自分で用意して行った方がいいと思います。

スタッフの方も親切ですし、拙い英語力でも対応してくださいます。楽しかったです!

There was a very rare trouble, so I couldn't see the sunset, but I was able to enjoy the beautiful scenery with a gradient from orange to blue after the sun had set. I was worried about the weather for stargazing, but we were blessed with clear skies during the viewing, and I was able to see a sky full of stars, including the Milky Way. The guide's explanations about the history, culture, and nature of the Big Island were very clear and made for a truly enjoyable time. Thank you very much.

We participated with four adults, including my son and his wife. Since it was a full moon night, I was worried about whether we would be able to see the starry sky, but it turned out to be a great decision. When we were looking at the stars, the moon had not yet risen, and after taking photos of the starry sky, the moon appeared. The sight of the full moon rising above the clouds was magical and just as moving as the starry sky. Since it was an English guide, I couldn't understand everything, but I appreciated that our guide, James, made an effort to use some Japanese.

息子夫婦を含む大人4人で参加しました。
満月の日だったので星空が綺麗に見えるか心配しましたが結果的に大正解でした。星空を見てる時は月はまだ出ておらず、星空を見て写真を撮って頂いた後に月が出てきました。雲の上から満月が出てくる様は幻想的で星空と同じくらい感動しました。英語ガイドなので全て理解する事は出来ませんでしたが、ガイドのジェームズが使える日本語は使おうという努力をしてくれ感謝です。

On the day, there were four of us, including my son. The guide provided instructions in English for the other couple and mixed in some Japanese for me.

Although we were a bit slow at times with the unfamiliar kayaking, they always kept an eye on us and waited. The waves were a bit high, so we couldn't jump from the rocks, but we were able to enter the cave as far as we could while ensuring safety.

They also made sure to allocate enough time for snorkeling, and everyone enjoyed it. It was clear that they really love interacting with Hawaii's nature and people. I definitely recommend this experience.

当日は私と息子を含めて4人。別のカップルと息子には英語で、私には日本語も交えてガイドして下さいました。

慣れないカヤックで途中遅れたりもありましたが、いつも目を配り待っていてくれたり。波が高めで岩からのジャンプは出来ませんでしたが、安全確保をしながら洞窟もギリギリまで入る事が出来ました。

シュノーケルも時間をしっかりとって下さり、みなさん楽しんでいました。ハワイの自然や人と関わる事がとても好きな様子が伝わって来ました。是非オススメします。

Tour guide was informative. Ride was comfortable. BLT bacon was really good. Veggie burger was more filling than the BLT. Stargazing was minimal due to full moon but fun. Best not to go during around full moon time. Download a star app like Night Sky to help enhance the experience. Dress for cold wind. You are going to want to take a lot of pictures so if if your hands get cold easily, bring mitts!

The guide was entirely in English, but since the guide was of Japanese descent, I was very grateful for the simple Japanese explanations provided. I was very satisfied to see the beautiful sunset and starry sky. I rated it one star less because I wouldn't be able to obtain the photos taken unless I posted this review (it seems that posting a review is mandatory when booking through Veltra).

すべて英語でのガイドでしたが、日系のガイドさんだったため簡単な日本語で案内していただき、大変ありがたかったです。
綺麗な夕陽と星空を見ることができ、大変満足でした。
星マイナス1としたのは、この口コミを投稿しなければ、撮影いただいた写真を入手できないためです(ベルトラでの申込の場合は口コミ投稿が必須のようです)。

Tips and suggestions

At the summit, temperatures can drop to around 6°C even in August, so a long-sleeved jacket is essential (you can borrow down jackets and ski pants). Since dinner is served early, before 5 PM, I think

頂上は8月でも6℃ほどまで下がるので、長袖の上着は必須です(ダウンやスキーパンツは貸していただけます)。
夕食の時間が17時前と早いため、軽食も持っていくと良いと思います。

Mauna Kea Summit Sunset & Stargazing Tour with Meal, Transportation & Guide
Excellent Tour Guide, Some disappointment

No doubt of the beauty of Hawaii and God’s Creation. Tour Guide (Francis) was excellent…knowledgeable, fun and caring (we had one participant having trouble with altitude so had to return to welcome center taking about 1 hour of the group’s time to go back and travel back up, however, care extended by Francis is to be commended).
Disappointed in that part of the tour was to look through a telescope (explicitly listed as part of the tour) but that did not happen. Vans were “dated” but did the job. Overpriced in our opinion of what the experience provided.

Kona Manta Ray Night Snorkel Tour - Small-Group Adventure from Keauhou Bay
Night manta ray
Activity Date: 2025/08/03 | Posted on: 2025/08/05

Really cool experience for the family. Adult kids of 23,21,18 really enjoyed it as well. Very friendly staff, manta rays got within inches of your face and even brushed up against you on occasion. Definitely an excursion that doesn’t take up a whole day or afternoon and you can squeeze in if your looking for something to do after dark

We had a fantastic time on the nighttime stargazing and sunset tour with James! We learned so much and had a memorable night - the sandwiches, sunset and stars were top notch!

I was able to see a lot of fish, and it was a wonderful experience. My son really remembers how delicious the chips we had on the boat were, to the point that he wanted seconds.

Just as we were returning to the port, there was a tsunami due to an earthquake in the Kamchatka Peninsula, which made us a bit anxious, but they safely returned us without any issues. I feel like I want to participate again.

魚もたくさん見られて、とても良い体験をせて頂きました。
息子は、船上で頂いたチップスが美味しくてお代わりしてしまうほどだったことがすごく記憶に残っているようです。

丁度港に帰る頃にカムチャッカ半島の地震の影響で津波が来たタイミングで、多少慌てましたが、問題なく送り返して頂きました。
また参加したいと感じています。

The ship was larger than I expected, and there were many people participating. Since there was no Japanese support, there were fewer Japanese people, but it was great for us to experience the overseas

Mauna Kea Evening Stargazing & Daytime Solar Viewing Tour with Dinner
Good guide but fell slightly short of expectations
Activity Date: 2025/07/31 | Posted on: 2025/08/01

I was disappointed with this tour for lack of hospitality, communication and false advertising. The tour guide is not an astronomer or someone who writes articles for astronomy mazagines or even a local Hawaiian. They are very knowledgeable, patient and friendly guides but also lack communication with the tour company. For instance, we had 10 people in our tour and they were told only 6 so he wasn’t prepared with enough hot chocolate or parkas. It may also be the reason he didn’t offer snacks or water to anyone and tried to get more people to drink coffee at 9 pm! I was also disappointed that we didn’t go to the Kona coffee farm as advertised in the itinerary and confirmed when they called. You also have to select your meal prior to arrival or seeing the options which is undesirable. Finally, when they called to confirm they told me not to bring anything - no water, jacket, hiking boots etc since all would be provided and tennis shoes were enough. First off, I came prepared with everything in my luggage but since they said not to bring a big bag or too many items we were underprepared. My son was freezing because the parkas are huge and they were passed out but left for people to get when they were freezing. Our tennis were covered in dirt and sand because we stopped at a beach and walked the sand. I would have to be informed in advance that we’re going to a beach and not the coffee farm and to have proper attire. The stargazing was nice and we saw a lot of stars and constellations but it was not pleasant because of the lack of preparation. I do not recommend this tour. If you book, don’t listen to their advice and come prepared with attire, water and snacks on top of the exorbitant price you pay. Or you could ask to go with the tour that matches the advertisement but I tried that already. Heed the warning. I didn’t and while we don’t regret it we regret the company.

The best sunset/stargazing experience.
最高の夕日/星空体験
Activity Date: 2025/07/30 | Posted on: 2025/07/31

The air at 4,207 meters was very clear and delicious, and I was able to see a beautiful sunset! A little lower down, I was able to observe the starry sky, and I saw shooting stars and satellites. The cocoa provided was also very tasty, and this was an activity that is hard to experience in Japan, including the environment! The guide was a local person who explained things in both Japanese and English, so I was able to enjoy the tour without any difficulties.

4,207メートルの空気はとても澄んでいておいしく、綺麗な夕日を見ることができました!少し降りたところで星空も観測でき、流れ星や人工衛星を見ることができました。支給されたココアも非常においしく環境も含めてなかなか日本では体験できないアクティビティでした!ガイドさんも現地の方でしたが日本語も交えて説明してくださり何不自由なくツアーを過ごせました。

Activity Date: 2025/07/30 | Posted on: 2025/07/31

The summit was very clear, and both the sunset and the starry sky were beautiful, which made me very satisfied. Since it was a crescent moon, it was 70% visible, so I could see it well, but with a full moon, the moonlight makes it harder to see the stars, so it might be good to check the moon's condition. There were eight Japanese participants, so we had a guide who spoke Japanese, which made it stress-free and very enjoyable.

山頂はとても澄んでいてサンセットも星空もとてもきれいで、とても満足しました。三日月だったので70%の見え方だったのでよく見られましたが、満月だと月の光で星はみえにくくなるので、月の状態を確認するのもいいのかも。日本人が8人参加したので、日本語ができるガイドさんで、ストレスがなくとてもよかったです。

I thought it would be better to confirm the phases of the moon and then decide on the schedule.

月の満ち欠けを確認して日程を決められるなら、その方がいいと思いました。

Such an amazing experience! Pictures don’t do justice of being up so high above the clouds. The sunset was gorgeous, the sandwich was good, the stars were incredible!

Shoyo was very kind and took great pictures!

人生を変える体験

I was moved to discover such a beautiful place on Earth. I'm glad I decided to participate.

I had always wanted to climb Mauna Kea, but since it's a difficult place to reach on my own, I joined a tour.

The breathtaking views at Mauna Kea are beyond words, enveloped in a quiet atmosphere that made time feel like it was stretching on, creating a sense of immersion.

The transformation from the blue sky in the afternoon to the sunset and then to the starry sky was magical, and it was so beautiful that it took my breath away.

The tour was conducted in English, but our tour guide, Shoyou, also provided explanations in Japanese, which made it easy to understand.

The light snack sandwiches were served near the summit rather than at the visitor center, and it was delicious to eat while watching the sunset!

The most enjoyable part was the stargazing. With the telescope provided, I was able to see the beautiful moon and stars, and the guide carefully explained how to identify the constellations and their origins, making for a very meaningful and fun experience.

I truly recommend this to anyone who is considering participating! Thank you very much.

地球上にこんな美しい場所があるのかと感動しました。思い切って参加して良かったです。

もともとマウナケアに登ってみたいと思っていましたが、自力で行くのは難しい場所のためツアーに参加しました。

マウナケアは言葉で表現できないくらい美しい絶景を見ることができ、静かな空気に包まれていて時が経つのが長く感じられ、没入感がありました。

午後の青空からサンセット、そして星空へと表情を変えていく様子は幻想的で、ため息が出るほど美しかったです。

ツアーは英語での催行ですが、ツアーガイドのしょうようさんが別途日本語でもご案内をしてくださったので、分かりやすかったです。

あと軽食のサンドイッチは、ビジターセンターではなく山頂付近で提供いただきましたが、夕陽を見ながら食べられて美味しかったです!

特に楽しかったのは天体観測です。ご用意頂いていた望遠鏡で、美しい月や星を見ることができたり、満点の星空に浮かぶ星座の見方や由来を丁寧に説明してくれたりと、とても有意義で楽しい体験ができました。

参加を迷われている方にも本当におすすめします!
ありがとうございました。

Tips and suggestions

As you ascend to the summit, the air becomes thinner, and the unpaved sections of the path can be bumpy, so it's a good idea to bring motion sickness medication for peace of mind. I participated in Ju

山頂へ行くにつれ空気が薄くなり、途中の道は舗装されていない箇所で揺れたりするので、酔い止めを持っていくと安心です。
7月の参加でしたが、薄手のセーターを着ていても寒く、集中するためにも防寒は必須です。
