Blue Cave Snorkeling Tour

I was worried about the heavy rain on the day of the event and called in advance, but I was told, "The sea in Shakotan is calm with no waves, so there’s no problem." As the rain intensified during the journey, I felt a bit anxious.

I walked to the beach wearing the marine boots and wetsuit that I had pre-ordered. The sea was not as cold as I expected, and we swam to the cave with the help of a friendly instructor. The water was very clear. Along the way, the instructor explained the marine life …
I was worried about the heavy rain on the day of the event and called in advance, but I was told, "The sea in Shakotan is calm with no waves, so there’s no problem." As the rain intensified during the journey, I felt a bit anxious.

I walked to the beach wearing the marine boots and wetsuit that I had pre-ordered. The sea was not as cold as I expected, and we swam to the cave with the help of a friendly instructor. The water was very clear. Along the way, the instructor explained the marine life we found, let us hold some, and we passed through shallow areas where seaweed stretched up to the surface.

The cave we aimed for was much narrower and darker than I had imagined. We all held onto a rope and moved deeper with our eyes closed. It was a bit scary since I couldn't gauge the distance and there were rocks if I reached out. This cave was also home to bats, which surprised me as there were so many. Please check the actual colors on-site.

Even those who can't swim can safely enter the water with a life jacket, so there's no need to worry. For those who lack confidence in swimming, you can be pulled along. This experience is also recommended for those who are a bit unsure about swimming. It’s nice to receive the data from the underwater camera as well. (The attached photos were taken with my own camera.)

I regret forgetting to have someone take a photo of us swimming from the sea floor.

Next, I want to challenge myself at Lake Shikotsu.

The staff were very kind when explaining the way to the equipment and swimming.
当日地元の天候が大雨で開催されるか心配し、事前に電話連絡するも「積丹の海は波もなく穏やかなので問題ないです」との事、道中雨が強くなったりする度にそわそわしながら伺いました。
事前に申告してあったサイズのマリンブーツやウェットスーツ等を着て歩いて浜辺迄移動します。
海も思ったよりは冷たくなく、親切なインストラクターのおねぇさんと洞窟まで泳いでいきます。
そして、海の透明度が高かったです。
途中見つけた海洋生物を説明して下さったり、手に乗せて下さったり海藻が水面まで伸びている浅瀬を通ったり・・・。

途中見つけた海洋生物を説明して下さったり、手に乗せて下さったり海藻が水面まで伸びている浅瀬を通ったり・・・。
お目当ての洞窟は思ったよりもとっても狭くて暗い。
ロープを全員で持って目をつぶって奥に進みます。
これが距離感覚も無いし手を伸ばせば岩だしで、ちょっと怖い。
そしてこの洞窟は蝙蝠が飛ぶ洞窟でした。
沢山居てそっちにもビックリ。
実際の色はぜひ現地で確認してみてください。

泳げない方でもライフジャケットで沈む事は無いので安心して海に入れます。
泳ぎに自信の無い方は引っ張ってもらえます。
ちょっと泳ぎに自信がないって方にもオススメ出来る内容でした。
水中カメラで撮ってくださったデータを頂けるのもうれしいですね。
(添付した写真は自分のカメラで撮影したものです)

海底から泳ぐ私たちを撮ってもらい忘れたのだけ心残りでした。

次は支笏湖にチャレンジしたいです。

Staffs are very kind when explain way to stuffs and swimming;)

It wasn't as blue as I expected, which was a bit disappointing.

I misunderstood that the snorkeling at the Blue Cave would last 45 minutes after the cruise from the boat, so it surprisingly went by quickly at the cave close to the beach. Perhaps due to the season, the underwater visibility wasn't very good. The color of the Blue Cave didn't appear very blue, and it might have been a timing issue since I participated at 3 PM. The surface of the water didn't look blue at all; it appeared greenish.

Perhaps due to the season, the underwater visibility wasn't very good. The color of the Blue Cave didn't appear very blue, and it might have been a timing issue since I participated at 3 PM. The surface of the water didn't look blue at all; it appeared greenish. Since I was looking from the surface, I thought it would be nicer if there wasn't any trash. Are there various points in the Blue Cave? There might be more beautiful spots, but I probably won't repeat the experience. The shop staff were interesting, kind, and nice. The road from Sapporo to Shakotan was really congested, and what should have taken less than two hours ended up taking three, making me worry that I would miss lunch. There were restaurants near the shop where you could eat seafood bowls. 船からのクルーズして、そこから青の洞窟で降りてシュノーケリングが45分だと勘違いしていたので
、浜から近い場所の洞窟で以外にあっとゆう間だった。
時期的なものなのか水中の透明度は良く無い。
青の洞窟の色はあまり青く見えず、3時からの参加だったのが時間的に良くなかったのかもしれない。
水面上は全く青く見えず、水面は緑に光って見えました。
水面で見ていたので、ゴミがなければもう少し綺麗だといいなと思いました。
青の洞窟もポイントが色々あるんでしょうか?もっときれいな場所もあるかもしれませんが、
リピートはしないか…

札幌から積丹方面がすごく混んでいて2時間弱で来れるはずが、3時間かかってお昼ご飯を
食べそこなうかと思いました。ショップ付近に海鮮丼など食べられるお店は有りました。

The experience location is a very beautiful sea where you can enjoy activities like swimming, in Amami. The meeting point is easy to find, and driving along the road, there was no chance of getting lost.

This activity is suitable for beginners exploring the sea for the first time. I hadn't swum in years, so I was a bit anxious about entering the water at first, but there’s no need to worry as the instructor pulls a float for those who can't swim. With life jackets, fins, and masks provided, ther…
The experience location is a very beautiful sea where you can enjoy activities like swimming, in Amami. The meeting point is easy to find, and driving along the road, there was no chance of getting lost.

This activity is suitable for beginners exploring the sea for the first time. I hadn't swum in years, so I was a bit anxious about entering the water at first, but there’s no need to worry as the instructor pulls a float for those who can't swim. With life jackets, fins, and masks provided, there’s no concern about sinking, and I quickly got used to it. Of course, those who can swim can dive in freely.

We were divided into two large groups, with about ten people in total, and we explored underwater at a leisurely pace. We were able to see sea urchins, sea hares, and other strange marine creatures that are not usually visible. Entering the Blue Cave and going a bit deeper, I was moved when I turned around and saw the entire water surface illuminated with a divine blue light.

The duration of 1 hour and 45 minutes was quite suitable for beginners. As long as you’re not resistant to water, this is an activity that anyone can enjoy, so definitely participate and create wonderful summer memories!
体験場所は海水浴などもできるとてもきれいな海、美国。集合場所などはわかりやすく、車で道沿いを走っていくと、迷うことはありませんでした。
初めて海を探索する初心者向きのアクティビティーです。もう何年も泳いでいないので、海に入ること自体最初は少し不安でしたが、 泳ぎができない人でもインストラクターがビートバンを引いてくれるので特に心配はいりません。しっかりとライフジャケット、フィンやマスクを装備するので、沈む心配はもちろんなく、すぐに慣れました。泳げる人はもちろん、進んでどんどん潜っていって大丈夫です…

初めて海を探索する初心者向きのアクティビティーです。もう何年も泳いでいないので、海に入ること自体最初は少し不安でしたが、 泳ぎができない人でもインストラクターがビートバンを引いてくれるので特に心配はいりません。しっかりとライフジャケット、フィンやマスクを装備するので、沈む心配はもちろんなく、すぐに慣れました。泳げる人はもちろん、進んでどんどん潜っていって大丈夫です。この回は、大きく2グループに分かれて、計10名程でゆっくりと水中探索をしました。
普段は見ることのできない、ウニやアメフラシ、その他不思議な見たことのない海中生物を見ることができました。青の洞窟に入り、少し奥の方まで行き、振り返ると水面全体に神々しい青の光が見られた時は感動的でした。
1時間45分という時間も初心者レベルにはわりとちょうど良かったです。
水に抵抗さえなければ、誰でも楽しめるアクティビティーなので、ぜひ一度参加して、楽しい夏の思い出をつくりましょう。

My first sea experience in Hokkaido
I heard that the sea is beautiful and there is delicious food, so I went to Shakotan.
In a word, it was quite good!!!
Unfortunately, a typhoon was approaching, and I was worried about whether I could participate, but I was able to safely encounter the amazing Shakotan blue and its creatures!
The guide who kindly and thoroughly showed us around was wonderful too!!!
北海道での初めての海
海が綺麗、美味しい食べ物があるという情報を聞き積丹に行きました。
一言で言うと、かなりよかった!!!
あいにく台風が来ており、参加できるか心配していましたが、無事、最高の積丹ブルーと生き物たちに出会うことができました!
懇切丁寧に、案内してくれたガイドさんも素敵でした!!!

It takes a bit of time from Sapporo, but I was able to enjoy sightseeing in the Shakotan Peninsula and Otaru after the tour, so in the end, I had a fulfilling day.

Considering safety, it can't be helped, but I wanted to dive like the guide without being too buoyant in the life jacket. Since it was a tour with just two groups, we had plenty of time.安全性を考えると仕方ないけど、ライフジャケットで浮きすぎてガイドの方のように、素潜りしたかった。
2組でのツアーだったのでたっぷり時間も取れました。

Thank you for participating in the Blue Cave snorkeling! When swimming, it's natural to want to go free diving, and I understand your dissatisfaction, even if it's for safety reasons. Please come back next time for diving! We look forward to seeing you!

The guide was a really bright and pleasant person, which was great. I wasn't very good at swimming, but they helped me by holding onto a float. The Blue Cave was sunny, but it was dark inside and the surface of the water wasn't that blue. The underwater was blue. The distance from the office to the sea was quite steep and challenging. It became a fun memory.ガイドさんは凄く明るく感じの良い人でよかったです。
泳ぎがあまり上手くありませんでしたが浮き輪に捕まって手伝っくださいました。
青の洞窟は晴れていましたが中は暗く水面はそこまで青くなかったです。水中は青でした。
事務所から海までの距離が急坂で結構ありそれがかなり大変でした。
楽しい思い出になりました。

I was worried about the typhoon, but there was no wind or waves, and I was able to experience it. I was concerned because I can't swim very well, but I was able to float with the life jacket, and the instructor was watching over us closely, so I felt safe exploring the ocean.

The underwater scenery was filled with sea urchins, allowing me to enjoy the essence of Shakotan, and the Blue Cave was even more beautiful than I had imagined, leaving me very satisfied.

I would love to participate again.

台風が心配でしたが、風も波もなく体験することができました。
あまり泳げないので心配でしたが、ライフジャケットで浮くことができたことと、
インストラクターさんがしっかり見ていてくださったので、安心して海の中を見ることができました。
海の中はウニがいっぱいで積丹感を味わえ、また、青の洞窟は想像以上にキレイで大満足でした。
また参加したいです。

楽しかったです。ありがとうございました。

Thank you for your review.
Although it was unfortunately a cloudy day, the cave looked very blue and we could see schools of fish. We hope you were able to feel the charm of the sea in Hokkaido, even just a little.
We look forward to seeing you again.
Thank you very much for your visit.

Thank you for joining us!
I'm Kai, your guide.
I'm glad I could take you to a cave that’s not easy to access.
It was beautiful, wasn't it?
It was amazing, right?
I'm satisfied that I could deliver an experience that can't be captured in photos.
The sea in Shakotan looks completely different depending on the weather that day.
I hope you can experience another kind of wonder with us again!
ご参加いただき ありがとうございますww

The wind was strong, and we weren't sure if we could reach the cave, but they took us there while keeping an eye on us. We could see the fish in the sea clearly, and the cave was glowing with a fluorescent blue light. Thank you for this precious experience.風が強く、洞窟まで行けるか分からない状況でしたが、私たちの様子を見ながら連れていってくれました。海の魚たちがよく見えて、洞窟は蛍光のブルーで光っていました。貴重な体験をありがとうございました。

This is Shuuko, your guide.
Thank you for your kind words.
That day was a great success with everyone trying together!
It was a luxurious tour where we could see both many fish and the blue cave.
On a calm day, leisurely exploring underwater is also enjoyable, so please come back to the sea of Shakotan again.
I would be happy to guide you.
ご案内しましたガイドの修子です。
嬉しいお声をありがとうございます。
あの日は皆さんでトライして大成功でしたね!
たくさんの魚たちと青い洞窟、両方見られるの贅沢なツアーになりました。
穏やかな日にゆったり海中散策も楽しいですので、是非また積丹の海に遊びに来てくださいね。
喜んでご案内いたします。
