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 best sunset and starry sky.
最高のサンセットと星空
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。
ハワイ島に行かれた際は星空とサンセットを見ていただくことをお勧めします。

Tips and suggestions

It was August, but I equipped myself with a lightweight down jacket and winter tights, and wore the borrowed cold-weather gear. I think it's better to be prepared for the cold.

8月でしたが、薄手のダウンと冬用のタイツを装備し、お借りした防寒着を着用しました。防寒対策はされた方が安心だと思います。

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.

いくつかの天文台を案内してくれて、また山頂から見たサンセットがとても綺麗でした。
山頂少し降りたところで天体観測をしました。

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!

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. It was an experience I will remember for a lifetime.

大変レアなトラブルがあり、夕日が沈むところは見れませんでしたが、沈んだあとのオレンジから青のグラデーションかかかった美しい景色をみることができました。
星空も空模様が心配でしたが、観賞時には晴天に恵まれ、満天の星空をみることができ、天の川もみれました。
ガイドの方のお話も、ハワイ島の歴史や文化、自然についてわかりやすく説明いただき大変楽しい時間でした。ありがとうございました。

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。

Mauna Kea Summit Sunset & Stargazing Tour with Meal, Transportation & Guide
Great memories were made!

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).

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
Activity Date: 2025/08/02 | Posted on: 2025/08/07
L&H

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.

The horses were beautiful and cute, and the female guide was very friendly, speaking slowly and kindly, which made it a lot of fun. I participated again this year, just like last year. It was truly enjoyable, just like before. There were also flush toilets, and they had a good selection of rental items like windbreakers, which was helpful. Additionally, the pet dogs and cats were unbelievably friendly, and they brought me a lot of comfort.

馬も綺麗で可愛くガイドの女性も非常にフレンドリーでゆっくり丁寧に話してくれて、とても楽しかったので、昨年に続き参加しました。前回同様本当に楽しかったです。水洗トイレもあり、ウインドブレーカーなど貸し出し用グッツもそろっていて助かりました。またペットの犬猫達も信じられない位人懐っこい性格で、彼らにも癒されました。

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 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.

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。

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!

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

Activity Date: 2025/07/05 | Posted on: 2025/07/28

We participated as a family of four. The other three members were beginners at horseback riding, but the staff was very attentive, and above all, the horses are smart, which made us feel at ease. The trail for the outdoor ride offers beautiful scenery with views of the sea, forests, hills, and rivers. They also take photos at a stunning viewpoint with the sea in the background, so even if you don't have the time to take pictures yourself, you can relax. During the ride, they provide explanations about the plants and animals. Although it's not a Japanese tour, if you can manage everyday conversation in English, you'll be able to enjoy the conversation fully.

家族4人で参加しました。私以外の3人は乗馬初心者でしたが、スタッフが気配りしてくれるのと、何よりお馬さんが利口なので安心です。外乗するコースは海、林、丘、川辺と景色が豊かで楽しめます。海をバックにした絶景ポイントで写真も撮ってくれるので、自分では写真を撮れる余裕のない方でも安心してください。外乗中は植物や動物についても解説してくれます。日本語ツアーではありませんが、日常会話程度の英語ができる方ならば十分に会話も楽しめます。

It's worth a visit.
They provided warm clothing, light snacks, and cocoa, and the guide actively encouraged us to take photos.
Additionally, the guide had extensive knowledge about the observatory and the night sky, and the explanations were very thorough, deepening our understanding.

I was moved!
The guide was bright, knowledgeable, and reliable, the scenery was wonderful, and the night sky was covered with unbelievable stars.
The sandwich at the summit and the cocoa under the starry sky were all so enjoyable.

ハワイ島 乗馬ツアー 3段に流れるウマウマ滝でハイキングや滝壺遊びもあり! <午前・午後/英語ガイド>

It's a tour without a Japanese guide, but you can enjoy it without any problems.

First, there is a lecture about horseback riding. Then, each child gets to ride a horse, and they are very gentle, so my son had no issues riding.

We lined up and went through the grasslands, moving into the woods. Along the way, there were horses grazing, which was very cute.

After passing through the woods, we took a break at the waterfall basin. You can wear your swimsuit in advance and swim in the river or ride a paddle boat. We had about 30 minutes, so we were able to enjoy it at a leisurely pace.

After the break, we returned the way we came, and the tour ended. The entire experience was in English, and I didn't understand most of the explanations along the way, but the experience itself was very good!

日本語ガイドが居ないツアーですが、問題無く楽しめます。

最初に乗馬についてのレクチャーがあります。続いて子供も1人一頭馬に乗りますが、とても大人しいので息子も問題無く乗っていました。

一列に並んで草原を抜け、林へと進みます。途中草を喰む馬も居てとても可愛かったです。

林を抜けて滝つぼの所で休憩。予め水着を着ておいて川で泳いだりパドルボートに乗ることが出来ます。30分ほど時間があるのでゆっくり楽しめました。

休憩後、来た道を戻ってツアーは終了です。
全編英語で途中の解説はほぼ分かりませんでしたが、体験自体がとても良かったです!

Tips and suggestions

Since there is no shuttle service, you need to come by rental car. I recommend the malasadas at Tex Drive In along the way; they were delicious!

送迎が無いので、レンタカーで自力で来る必要があります。途中のTex Drive Inのマラサダが美味しかったのでオススメです。

The tour included a visit to the Onizuka Visitor Center, sunset viewing at the summit, a tour of various observatories from around the world, stargazing at the best spots, and sandwiches. At the summit, a sea of clouds spread out, and the sunset behind the observatory painted the clouds in shades of crimson, which was incredibly beautiful. The countless stars filling the sky were a sight that could only be seen by coming this far, and it was truly moving. Additionally, our guide, Mr. Shoyou, was Japanese, so his explanations about the night sky were easy to understand, and he was supportive in every aspect. The rental of warm clothing was also very helpful.

オニヅカビジターセンターの見学、頂上でのサンセット鑑賞、各国の天文台の見学、ベストスポットでの星空観察とサンドイッチ付きと全て揃ったツアーでした。
頂上は雲海が広がり、天文台をバッグに沈む夕陽は雲を茜色に染まりとても美しかったです。今にも降り注いでくるかと思うほど空一面に広がった星の数々はここまで来ないと見られない光景で感動しました。また、ガイドのショウヨウさんは、日本人の方なので、星空の説明も分かりやすく、全ての面において心強かったです。防寒着のレンタルも助かりました。

I can't catch even a mahi-mahi, let alone a marlin. Wouldn't it be better to move the boat closer to where the baitfish are? Am I watching too much of "Ooma's Tuna Fishing" on TV? (laughs)

I think it depends on the weather.
天気によると思います。
Activity Date: 2025/07/19 | Posted on: 2025/07/20

Unfortunately, due to the weather, I couldn't see the sunset from the mountaintop, but I was able to see it a little lower down. The starry sky, of course, has a number of stars that can't be compared to those in Japan, but it wasn't different from the night sky visible from the hotel where I stayed. However, thanks to our guide, Shoyou, who diligently searched for spots to view the sunset and stars and provided detailed explanations, I was able to participate enjoyably.

あいにくのお天気で、夕陽は山頂から見れず、少し下ったところで見ることができました。
星空も、もちろん日本とは比にならない星の数ですが、宿泊先のホテルから見える夜空と変わりませんでした。
でも夕陽や星空の見えるところを一生懸命探して、詳しい説明もしてくださるガイドのショウヨウさんのおかげで、楽しく参加させていただけました。

We are a family of 4 with 2 teenagers, we had a great time with our guide at the stargazing tour. Our highlights were the lava caves, watching the sunset as well as stargazing. The sky was unbelievable and we learned a ton with our very knowledgeable guide.

Highly recommend.

The guide was fluent in Japanese and talked about altitude sickness measures and various topics during the ride, which made me feel at ease and enjoy the experience. The weather was great, and it was the best experience. I want to go to Hawaii Island again! Next time, I want to join the sunrise tour! ☺︎

I signed up for the tour because there was only an English option, but it seems a certain number of Japanese participants gathered, and they held a Japanese tour for us. I was glad to receive explanations in Japanese about altitude sickness and the stars, which were quite specialized. Our guide, Sho-chan, was friendly and made it enjoyable. The timing for the sunset and stargazing was perfect, and I'm really glad I participated in the tour.

英語でのツアーしかなかったので申し込みましたが、日本人参加者が一定数集まったそうで日本人むけの日本語ツアーを開催してくださいました。高山病へのアテンションや星の説明など専門的な話を日本語で説明受けれてよかったです。ガイドのしょうちゃんはフレンドリーで楽しかったです。

Tips and suggestions

Even in mid-summer, the summit can be below freezing, so bringing warm clothing is essential. I brought a fleece, and even though I was lent a down jacket, it was still cold.

真夏での参加でも山頂はマイナスになるので防寒具の持参が必須です。フリースを持参して、ダウンジャケットを貸してくださっても寒かったです。
