Mauna Kea Summit Sunset and Stargazing
マウナケア山頂サンセット・星空
Activity Date: 2025/12/16 | Posted on: 2025/12/21

The weather forecast was bad, but the sunset at the summit was wonderful with a salmon pink sky! The starry sky also defied the weather forecast, and I was able to observe the Milky Way, which made me very satisfied. The guide was fluent in both English and Japanese, and the explanations were easy to understand, allowing us to have a truly wonderful time!

天気予報は悪かったのですが、山頂でのサンセットはサーモンピンクの空が広がりとても素敵でした!星空も天気予報を覆し、ミルキーウェイも観察できて、大変満足でした。
ガイドの方も英語・日本語堪能で、解説もわかりやすくとても素敵な時間が過ごせました!!

It was the best starry sky of my life.
人生で1番の星空でした
Activity Date: 2025/12/17 | Posted on: 2025/12/18

The stars were very visible. I have seen stars from the 8th station of Mount Fuji in the past, but this time there were more and they were more beautiful. I'm glad I participated in the tour.

The sunset was beautiful, but it felt just as I expected.

The BLT sandwich we were given for dinner was something I wasn't expecting, but it was packed with ingredients and delicious, haha.

星が非常によく見えました。
過去に富士山8号目から星を見たことがありますが、今回の方が綺麗かつたくさん見れました。ツアー参加してよかったなと思います

夕日も綺麗でしたが期待通りといった感じ

夕食として配られたBLTサンドは期待していなかったですが、具沢山で美味しかったです笑

Mauna Kea's sunset and starry sky
マウナケアの夕日と星空
Activity Date: 2025/12/16 | Posted on: 2025/12/18

It was an English tour, but I appreciated that they provided explanations in Japanese here and there. The sunset at Mauna Kea was truly beautiful, and as we drove up, I could feel the temperature dropping gradually with the increasing elevation, which made me realize just how high the mountain is. I can't believe we could drive all the way to the summit!

The photo opportunities were fantastic, with many great poses suggested, and the friendly service was reassuring. We were the only Japanese people in the car, so I was very grateful for the care we received. The night sky was also breathtaking, with the Milky Way visible—it was an emotional experience!

I participated in a similar tour with a different company about ten years ago, but I noticed some great differences this time: the sandwiches were delicious, they took a lot of photos, and the number of silversword plants at the Onizuka Center has significantly increased thanks to conservation efforts. I definitely think this is a must-do tour on the Big Island!

英語のツアーでしたが日本語でも所々説明してくれて助かりました。
マウナケアの夕日は本当に美しくて、たどり着くまでの車の中でも少しずつ標高が上がるたびにだんだん寒くなってくるので本当に高い山なんだなと実感します。
頂上まで車で来られるなんて信じられない!
写真はたくさん素敵なポーズを提案してくれてフレンドリーな対応にホッとしました。車の中で日本人は私たちのみでしたがケアいただいて大変ありがたかったです。
夜の星空も天の川が見えて感動的でした!
昔10年前も別の会社の類似ツアーに参加しましたが、サンドイッチが美味しいこと、たくさん写真をとってくれること、オニヅカセンターの銀剣草の数が保護の甲斐あってとても増えていることなど良い違いを感じました。
ぜひハワイ島にはマストなツアーだと思います

If you have down jackets and pants to lend, the cold won't be a problem at all. The women's restroom at the Onizuka Center gets quite crowded, so it might be better to go early.

オニヅカセンターの女子トイレはかなり混むので早めに行ったほうがいいかも。

The sunset and starry sky from the summit were breathtaking and truly moving. I was able to understand the explanations about the stars well since they were provided in Japanese.

I was a bit worried about the altitude and altitude sickness, but I was comfortably taken care of with a car ride and was lent warm clothing, so I was able to enjoy my time there. Thank you very much!

Bite Me Sportfishing Trip - Kona Shared & Private Charters from Honokohau Harbor
Nice day on the ocean
Activity Date: 2025/11/20 | Posted on: 2025/12/13

Crew was so nice & helpful. Very disappointed that we didn’t even get one bite. They said they usually have live bait to try also but didn’t bring any that day. I know that no one can control the fish but I wish they would have had an alternative to try. It was a beautiful ride on the boat & very comfortable shaded area. I would try them again.

The sunset viewed from the sacred summit of Mauna Kea was the best, and the starry sky was truly beautiful and moving. The summit was much colder than I expected, so I recommend going dressed warmly. The hot cocoa enjoyed at the top of the mountain was also fantastic! I took some great photos, which became wonderful memories. Thank you to our guide, Shoya.

The sunset and starry sky were breathtaking, and I was truly moved. I was a bit worried about the cold and altitude sickness, but I had such a wonderful time that it didn't bother me at all. I wanted to capture the stunning scenery in photos, so I brought a camera and tripod, even though I'm a complete beginner. With the support of the guide, I was able to take many beautiful pictures.

The sunset from the summit of Mauna Kea was amazing! I couldn't join the Japanese guided tour due to scheduling conflicts, so I participated in the English guided tour, but I was able to listen to the explanations about the observatory and the stars in Japanese. Thank you so much! I was able to see my zodiac sign, Capricorn, and received explanations about it. I encountered Subaru, Betelgeuse, and many stars. It truly became a wonderful memory.

I signed up to enjoy the sunset and stargazing from the mountaintop. Since we traveled by car, it was easy to head to the summit, but in reality, reaching an altitude of 4,200 meters involved a 20-minute journey on a gravel road, along with battling the invisible threat of altitude sickness, which was quite the challenge! After enduring headaches and slight breathlessness, a breathtaking view awaited us at the top!

Fortunately, we were blessed with good weather and were able to enjoy the most beautiful sunset and a sky full of stars, making it a perfect 120-point tour experience! Lastly, I experienced mild altitude sickness for the first time, but I found that listening to the staff's advice helped alleviate the symptoms. However, I recommend not overexerting yourself and moving around too much.

山頂からのサンセットと天体観測を楽しみに申し込みました。
車での移動でしたので手軽に山頂へ向かうことができますが実際には、標高4200mの高さまで辿り着くには20分ほどの砂利道を通ったり、見えない高山病との戦いもありました笑
頭痛がしたり若干の息苦しさを耐え忍んだ暁月には壮大すぎる絶景が待っています!!
私たちは幸いにも天候に恵まれ、最高の夕焼け、満点の星空を眺めることが出来、120点満点のツアーを体験することができたことに感謝します!
最後に初めて軽度の高山病になりましたが、高山病はスタッフのアドバイスを聞き、楽になりますが調子に乗って動き回らないことをお勧めします。

I was able to enjoy a world I've never seen above the clouds! The stars were so numerous when it got dark that I couldn't even recognize the constellations, which was very moving. Our Japanese guide explained about the observatory and the stars in a way that was easy to understand, and they patiently helped us until we could find the constellations.

The road to the summit was bumpy, and I felt a bit of discomfort at the top, but having the tour guide with us made me feel at ease.

I'm really glad I participated in this tour!

It seems that during any season when the moon is out, it's difficult to see the stars. I recommend checking the time more than just the moon phases before participating.

The sunset viewed in the clear air was truly beautiful. It might have been the first time I focused solely on the "sunset" without needing to think about anything else. It was simply beautiful. The stunning scenery before and after the sunset allows for a wonderful time that lasts longer than expected. Additionally, I was able to see the Venus Belt when I looked back, but this time, due to volcanic gas, I couldn't see the green flash. I would like to participate again the next time I visit the Big Island of Hawaii.

澄んだ空気の中見る日没は本当に美しかったです。
何かを考える必要のない中で「日没」に集中したのは初めてかもしれません。ただただ美しいものでした。
日没の前後で美しい景色は広がっているので、想定よりも長い間、素敵な時間を過ごせると思います。

Loved this tour - our tour guide was very accommodating and knowledgeable and we saw some beautiful spots of the island. Definitely recommend this trip as you get to see a lot in one day.

This tour was highly recommended! The view from the summit was amazing, and the experience of watching the sunset and stargazing really lifted my spirits. Additionally, the guide covered the challenging parts, which made it much easier on both my body and mind.

The tour takes half a day, but during the travel, I listened to the guide's explanations, and at each spot, we took our time to thoroughly explore Mauna Kea, making for a fulfilling experience. I think preparing to go on your own would be quite difficult, but this tour takes care of altitude acclimatization, time management for descending, providing warm clothing and telescopes, as well as sandwiches and hot cocoa. Plus, I could rely on them for the long drive, making it a very convenient experience.

Being able to drive to this altitude is rare worldwide, and this tour minimizes the burden while maximizing the experience. Overall, it was fantastic, and there were no inconveniences at all.

とてもオススメできるツアーでした!
頂上からの眺めは素晴らしく、日の入りも星見も気分が上がる体験です。
そして、大変な部分をガイドさんがカバーしてくれて、心身の負担が少なかったです。

ツアーは半日を要しますが、移動ではガイドさんの説明を聞き、各スポットではそれぞれ時間をとって、マウナケアをしっかりと見て回り、充実した時を過ごせました。
個人で行くには準備が大変だと思いますが、このツアーでは高地順応な下山の時間管理、防寒着や望遠鏡の準備、サンドイッチやホットココアの用意もしていただき、また長距離の運転もお任せできるので、とても手軽に体験ができるようになっています。
そもそもこの高度に車で行ける事自体が世界的に稀ですが、さらに負担を少なく、体験を最大化してくれているツアーです。

You can borrow winter clothing, but you should still bring your own winter inner layers and hand warmers. The summit is freezing cold, so if you're not prepared, you won't be able to stand outside.

防寒着は貸してもらえますが、それでも冬用のインナーやカイロなどを持っていくべきです。頂上は凍てつく寒さなので、準備しなければ外に立っていられません。
