All Reviews for Japan Hidden Gems: Secret Islands

Thank you for discovering the nature of Iriomote (Amur Falcon), the water buffalo cart to Yubu Island, and the wonderful cycling tour of Taketomi Island. Next year, I will walk around Taketomi Island all day.

西表の自然（アンムリワシ）発見、由布島への水牛車ありがとう、そして竹富島を自転車で観光素晴らし。来年は、一日中竹富島を歩いて廻ります。

I learned a lot from the clear explanations about mangroves and primary forests! The guide answered various questions patiently, and the bird talks were so interesting that the day flew by. In the mangroves, I enjoyed a calming canoe tour in the peaceful natural surroundings, which was very soothing. At Kinsakubaru, I was able to see cute and mysterious plants, and I was lucky enough to spot some endemic birds, making it an unforgettable experience. Thanks to this tour, I got to know more about Amami Oshima and grew to love it even more!

マングローブや原生林のことをわかりやすく説明していただき非常に勉強になりました！いろいろな質問にも丁寧に答えていただき、鳥トークなどおもしろくて一日があっという間でした。マングローブでは、自然の穏やかな雰囲気のなかカヌー散策してとても癒されました。金作原では、かわいい不思議な植物たちや運良く固有種の鳥たちも見ることができ、本当に忘れられない経験になりました。こちらのツアーのおかげで奄美大島のことをよく知ることができて、より好きになりました！

The bus driver, who was also the guide for the mangrove tour, was driving alone, and I could feel their effort. I think it was good because I was able to hear some enjoyable stories.

バスの運転手、マングローブの運転手が一人で運転しながらガイドをしていたので頑張りが伝わって来た。楽しい話も聞けたので良いと思う。

Among the many remote islands, I was able to enjoy a compact and well-planned sightseeing experience. It was my first visit to Ishigaki Island, and I was able to fully appreciate the beauty of the nature and scenery of the Yaeyama Islands, as well as the unique charm of each island. I absolutely recommend it.

On the ferry to Iriomote Island, I paid 500 yen for a premium seat, and the view from next to the captain's seat was amazing. I was moved to be able to take commemorative photos.

The mangrove forest made me truly feel like I was in a tropical paradise, and the water buffalo on Yubu Island were incredibly cute. The relaxed atmosphere and the songs played on the sanshin added to the ambiance.

On the glass-bottom boat in Taketomi, I was able to see many fish, including the clownfish. Everything was just fantastic.

離島がいくつもある中で、計画的にコンパクトに観光ができました。初めて訪れた石垣島でしたが、八重山の自然と景色の美しさ、それぞれの島の良さを堪能することができました。絶対オススメです。西表島に渡る船では500円出してプレミアムシートにしましたが、船長席の脇から眺める景色は最高でした。記念撮影をさせていただき感動でした。
マングローブの林は南国に来た実感が湧き、由布島に渡る水牛もとても可愛いらしかったです。のんびりとした時間が流れ三線での歌も雰囲気を盛り上げてくださいました。
竹富のグラスボートではカクレクマノミ始め沢山の魚を見ることができました。とにかく全て最高でした。

The shuttle service to the hotel allowed us to efficiently visit Iriomote Island, Yubu Island, and Taketomi Island all in one day.

I don't think I could have planned such an efficient trip on my own.

The water buffalo on Yubu Island really gave me a sense of being in a foreign land, and it was a lot of fun.

Renting a bicycle on Taketomi Island was definitely the right choice! Although our stay was a bit short and we couldn't stop by any shops, I was very satisfied with visiting the beaches I wanted to see, including the Star Sand Beach!

ホテルまでの送迎もあり1日で西表島～由布島～竹富島と３島を効率よく回れました

自分でプラン立ててたらなかなかここまで効率よく回れないと思いました

由布島の水牛がとても異国を感じさせてくれて楽しかったです

竹富島は自転車借りて正解！少し滞在時間が短かったのでお店などには寄れなかったけど行きたかった海岸や星の砂のビーチを巡れて大満足です！

There was a lot of moving around, and I felt that the time spent at each sightseeing spot was a bit lacking. It might be good for those who want to efficiently visit many places in one day.

移動が多く、それぞれの観光時間が少し物足りなく感じました。効率よく一日でたくさん回りたい方にはいいかもしれません。

Canoeing and snorkeling were both my first experiences in life.

Regarding canoeing, the location was a subtropical jungle, and it felt like we were navigating through a river surrounded by mangroves.

Snorkeling was an event where we entered the beautiful sea and swam while observing cute coral reefs and fish. The guide was incredibly kind and gently pointed out the highlights, allowing us to enjoy ourselves without any prior planning. Even if you can't swim, you can still enjoy snorkeling, so I highly recommend it.

I had an amazing experience doing something I normally wouldn't get to do, and it completely cleared away my usual stress. I would love to participate again.

カヌーに乗るのもシュノーケリングをするのも人生初めてでした。
カヌーについて、場所は亜熱帯のジャングルで、マングローブに挟まれる川を潜り抜ける感じでした。
シュノーケリングは美しい海に入り、泳ぎながら可愛い珊瑚礁と魚を見るイベントでした。
ガイドの方がすごく親切で、優しくポイントを教えてくれて、事前に何も考えずに遊びに行けます。泳げなくても、シュノーケリングを楽しめられますから、非常におすすめです。
普段体験できないことを最高に体験できて、普段のストレスを一掃しました。
また参加したいと思います。

It was raining, and the boat to Iriomote Island was rocking quite a bit, but when I boarded the mangrove cruise ship, the rain lightened up and it was great to open the windows for viewing. The boat got close to the sights, and the guide was very clear and informative, which was wonderful. The water buffalo on Yubu Island were also interesting, and the guide's stories were entertaining, but it seemed that from the very back seat, the voice didn't reach very well, so I recommend sitting at the front!

雨が降っており、西表に行く船はよくゆれたがマングローブのクルーズ船に乗った時は、小雨になり窓を開けての見学はとても良かったです。近くまで船が寄ってくれ、ガイドの方も分かりやすくとてもよかったです。
由布島の水牛も、ガイドさんの話が面白くてよかったが、一番うしろの席だと声はあまり届かなかったようなので、一番前がお勧めですね♪

The explanation before the activity was thorough, and everyone was kind, allowing us to enjoy the activity with peace of mind. Additionally, we got to hear stories about the unique animals of Iriomote, which made it all the more enjoyable.

アクティビティ前の説明も丁寧で、みなさん優しく安心してアクティビティを過ごせました。
さらに西表特有の動物のお話とか聞けて、色々楽しかったです。

I was able to efficiently visit three remote islands.
(I think it would have been difficult for an individual on their first time.)
This is a recommended tour for first-timers.

離島３島をとても効率よくまわることができました。
（初めてで個人ならば難しかったと思います。）
初めての方におすすめのツアーです。

I was grateful for the shuttle service from the hotel. Although there was no tour guide, I had no trouble and was able to enjoy sightseeing smoothly. It was nice that I could use the bus to visit the village and Kaiji Beach during my free time on Taketomi Island.

ホテルから送迎があるのが有り難かったです。
添乗員は居ないけど困ることはなくスムーズに観光出来ました。
竹富島はフリータイムでしたがバス利用で集落やカイジ浜に行けたので良かったです。

The bus driver's storytelling was excellent.
The stories were so engaging that the atmosphere in the bus was lively.

This was my first time visiting, and although it was a whirlwind one-day tour,
everyone was very satisfied, especially since it was my mother's wish to go.

I have created more memories with my mother on this trip. ♡

バスの運転手さんのお話が上手。
〇み〇ろ並みのお話で、車内盛り上がりました。

今回、初の上陸、駆け足での1日のツアーではありましたが、
「行きたい」と言ってくれた母の立っての場所という事もあり、
同行者全員大満足でした。

母との旅の思い出がまた増えました♡

There is a walking course in Yufushima, and I was truly able to enjoy nature surrounded by tropical trees! The lunch was also delicious Okinawan cuisine.

由布島の中は散策できるコースがあり、まさに南国の木々に囲まれた自然を満喫できました！昼食も沖縄料理で美味しかったです。

Despite it being a night tour, the weather forecast predicted rain. The day before, we had a detailed discussion about ① the possibility of a weather forecast error, ② what to do in case of light rain, and ③ what to do in case of heavy rain. On the day of the tour, we decided to go ahead despite the "weather that might go from light rain to heavy rain." As a result, it turned out to be a very satisfying tour where we encountered seven birds. Their short ears, short legs, and gestures were incredibly moving and cute.

I was trying to spot them myself in the center of the vehicle, fully focused and alert, but it was all thanks to our guide, Mr. Kawashima, that we found them. Unfortunately, I couldn't capture any good photo opportunities, so I have no pictures to show. For those participating in the tour who want to take at least one photo, it might be better to leave the spotting to Mr. Kawashima and be ready to "click the shutter at any time."

Additionally, we saw the Amami woodcock just sitting on a tree, the calls of the Japanese scops owl, and the green snake raising its head high, among others. Thanks to Mr. Kawashima's attentive guidance and appropriate local information, we had a very fruitful and valuable experience that went by in a flash. Thank you very much.

Unfortunately, the photos I took are not good enough to upload. I apologize for that.

ナイトツアーなのに天気予報は雨。
前日から　①天気予報の間違い　②小雨の場合　③土砂降りの場合
と、綿密な打ち合わせをして下さいました。
　で、当日は「小雨から本降り　かもしれない天候」の中、思い切って決行。
結果は、7羽に遭えるという、とても満足なツアーになりました。
短い耳、短い脚、しぐさ、とても感動的でかわいい。
　車の中央で自分で見つけようと、180度神経を研ぎ澄ましていましたが、見つけたのは、すべてガイドの川島さん。シャッターチャンスを上手くつかめず、残念ながら1枚も写真が残りませんでした。
ツアーに参加される方で、1枚でも写真を残したい方は、発見は川島さんにお任せし、「何時でもシャッター」で、スタンバイされた方が良いかもしれません。
　その他、ぼーっと木に止まっているだけのアマミヤマシギ、声だけのコノハズク、鎌首を思いっ切りもたげたアオヘビ、等々。
ガイドの川島さんの、丁寧なご対応と適切な現地案内のお陰で、
あっという間の、とても実りのある貴重な体験をさせて頂きました。
本当に、ありがとうございました。
なお、残念な写真ばかりで、アップロードに耐えられません。申し訳ございません。

The guide was very kind and attentive, providing thorough explanations all the way to Taiko Rock. As a trekking beginner, I caused various inconveniences, but I am sincerely grateful for the opportunity to participate. Thank you very much.

とても優しい気遣いのあるガイドさんで、太鼓岩まで丁寧に説明していただきトレッキング初心者で色々とご迷惑をおかけしましたが参加させて頂き心から感謝しています。ありがとうございました。

I was able to efficiently explore each island in a short amount of time while truly experiencing their charm. I would like to request this again.

短時間で効率良く回りながら、それぞれの島の魅力もちゃんと感じることができました。またお願いしたいです。

I was able to relax on Iriomote Island and Taketomi Island in just one day. The colors of the sea and sky were wonderful, so I've decided to go again in June. Next time, I want to experience the sunset and stargazing.

1日で西表島と竹島をゆったりできました、海や空の色が素晴らしく6月に再度いくことにしました。
次回はサンセットや星空観察など体験したいと思います。

It was very beautiful!
The person was very friendly, and we were able to take photos in a fun atmosphere!
I think I will ask again when I come to Miyako Island!

とても綺麗だった！
とても気さくな方で楽しい雰囲気で撮影することが出来ました！
また宮古島に来た際はお願いしようと思います！

I participated with four friends, and it was fun to feel the power of nature in the mangroves while canoeing. The weather was great, so we were able to snorkel in the best conditions and create wonderful memories! The instructors were friendly and easy to talk to, which was nice! Thank you very much! ^_^

友達4人で参加しましたー、カヌーはマングローブの自然のパワー感じれて楽しいかったですし、晴れたので最高のコンディションでシュノーケリングできていい思い出ができました！インストラクターのお兄さん達も話しやすくて明るくてよかったです！ありがとうございました^_^

I was very satisfied that all the places I wanted to visit were included. It was a plan that would have been impossible to organize on my own; truly a professional from the area.

行って見たかった場所がすべてそろっていて大満足でした。個人で計画は無理なプランさすが現地のプロです。

You can efficiently explore Mishima in one day, and there are plenty of highlights to see. I recommend it for those visiting Yaeyama for the first time.

The boat from Ishigaki to Iriomote can be quite rocky for a while after departure, so be cautious. Now, it feels more like a roller coaster ride, which is amusing.

Yufu Island feels like a paradise of tropical plants and butterflies. The lunch was also delicious.

If I come to Taketomi Island again, I think I will rent a bicycle.

１日で三島を効率よく回ることができ、しかも見どころ沢山。初めて八重山に行く方にオススメです。
石垣から西表に向かう船は、出発からしばらく凄く揺れるのでご注意。今となっては、ジェットコースター感覚でご愛敬という感じ。
由布島は熱帯植物と蝶々の楽園という感じ。お昼ご飯もおいしかった。
竹富島は、今度来ることがあればレンタサイクルを借りようと思う。

I participated in this trip because I wanted to see the islands of the Yaeyama Islands during my first visit to Ishigaki Island.

It was great to efficiently tour Iriomote Island, Yufu Island, and Taketomi Island in one day.

The lunch on Yufu Island was delicious, featuring a variety of Okinawan dishes. It was also fun to leisurely cross while listening to the sanshin and songs on the water buffalo cart.

On Taketomi Island, I chose the free walk plan, but I took a shuttle from the port to the village to tour the area by water buffalo cart, which was relaxing. After that, we went to see the ocean, so I missed the 4 PM boat and took the 5 PM boat instead. I was able to enjoy a lot of sightseeing, which was very nice.

初めての石垣島旅行で、八重山諸島の島を見てみたくて参加しました。

西表島、由布島、竹富島を効率よく1日で観光出来て良かったです。

由布島でのランチも沖縄のお料理盛りだくさんで美味しかったです。
水牛車で、三線と歌を聴きながらのんびり渡るのも面白かったです。

竹富島ではフリーウォークプランを選びましたが、港で集落を水牛車で周る観光の送迎車で集落へ行き、ゆっくり水牛車で周りました。
その後、海も見に行ったので、16時の船には間に合わず17時の船に乗りました。
たっぷり観光出来てとても良かったです。

This is an efficient tour for first-timers. I understand that it's important to manage a lot of tourists smoothly, but it was a bit disappointing to hear comments like "Everyone is waiting!" or "Please take photos later!" in a somewhat harsh tone when some people were a little slow. On the day of the tour, the weather was bad; we managed to avoid the rain, but the strong winds made the waves high, and the high-speed boat was quite shaky. I took motion sickness medication, but I still felt a bit unwell. I think it's safer for those who get seasick to bring their own medication. I don't think it's possible to visit all three islands in one day on your own, so I believe this is a good tour. The bus driver and the mangrove guide were easy to understand and shared enjoyable stories.

初めての方には効率よく回れるツアーです
たくさんの観光客の方をスムーズに回す為なのはわかりますが、少し遅い方がおられると「みんな待ってますよ！」とか「写真は後にしてください！」など若干キツイ口調なのが残念だした　当日は天候が悪くなんとか雨は逃れたものの強風で波も高く高速船がかなり揺れて酔い止めを飲んでましたが少し気分が悪くなりました　船酔いされる方は薬を持って行かれた方が安心かと思います
個人では3島を1日で回れないと思うので良いツアーだと思います　バスの運転手さん、マングローブのガイドさんはわかりやすく楽しいお話でした

My companion got injured partway through and had to descend, but the guide kindly accompanied us down, which was a great help. (Fortunately, the injury was minor.) Perhaps because we avoided the busy times, we encountered a group of Yakushima macaques and Yakushima deer at the village ruins! Although we didn't reach the summit, we thoroughly enjoyed the nature of Yakushima.

連れが途中で怪我をして下山することになりましたが、ガイドさんがフォローのため一緒に下山してくださり大変助かりました。
（幸い怪我も軽く済みました）
混雑する時間をはずれていたからか、集落跡でヤクサルとヤクシカが集まっているところに出会えました！完登はしなかったものの、屋久島の自然を十分楽しめました。

I didn't expect the water buffalo carts on Yubu Island to be so crowded. In the posters I often see, there's usually just one buffalo, so I was a bit surprised. It looked like they were racing.
I wanted to take my time to observe the changes in the tide at Nakama River.

　由布島の水牛車が、あんなに混んでいるとは思わなかった。よく見かけるポスター等では、一頭のみが多いので、少し驚いた。レースをしているようだった。
　仲間川は干満の違いが、分かるほど時間をかけてみたかった。

I participated with my 5-year-old child. There was no prior communication, and we were guided to board the bus at the hotel on time and check in at the travel agency counter at the terminal for the island trip. There, we received tickets for each attraction and stickers to wear on our chests before departure. There were staff members at various locations who provided proper guidance, so there were no issues at all.

We traveled to the island by boat. There are first and second floors, with the second floor being paid seating (500 yen for adults, free for preschoolers). Even in March, there were many tour guests, so the first floor was crowded, and we opted for the paid seating on the second floor. It’s recommended as you can also go out to the terrace and see the sea.

We enjoyed a slow ride on a water buffalo cart to Yubu Island. We savored the Okinawa time while crossing the transparent sea at a leisurely pace. My child said that the water buffalo cart was the most fun part of this trip.

On Yubu Island, we had 90 minutes to explore, but since that included meal time, we couldn’t take our time as much as we would have liked. If we had about two hours, we could have walked around the entire island a bit more, which was a bit disappointing. There are beautiful beaches, so I think bringing sandals, water for washing feet, and towels would make it enjoyable for children. There’s also a gelato shop with flavors like awamori, island lemon, and brown sugar-soaked rum raisin, which were all very delicious.

There’s a secret base (like a treehouse, swings, etc.), feeding the water buffalo, and many butterflies flying around, which was a lot of fun.

The mangroves on Iriomote Island were even more enjoyable with explanations provided. It was truly overwhelming, as there are mangroves everywhere; while there are mangroves on Ishigaki Island too, this was impressive.

You can go to the island on your own, but the tour took us around efficiently, which was helpful. It was particularly smooth with no waiting times.

For meals on Yubu Island (bento), children order on-site. There were options like curry and Okinawa soba, so there was no trouble finding something to eat, but I don’t think there was anything like a children's lunch. The bento was a mix of Okinawan cuisine, with many things I had never tried before, and it was delicious. Some items like tempura were cold, but since it was a group meal, I thought it was sufficient.

The bus back to the hotel departed an hour after we arrived at the terminal, so we took a taxi home. There are many shops near the terminal, so I think it would be nice to stroll around before heading back. For those who want to take the return bus, it seems you can apply at the counter on the day of the trip.

Thank you for the wonderful memories of a fun trip.

5歳の子供と参加しました。
特に事前連絡はなく、当日ホテルで時間通りにバスに乗車し、離島行ターミナルの旅行会社のカウンターで受付するように案内されました。
そこで各アトラクションのチケットと、胸に貼るシールももらい出発。
各地に案内のスタッフさんがいて、きちんと案内してくださるので何も問題なかったです。

離島までは船で移動します。１階と２階とあり、2階は有料席です。（大人一人500円、未就学児は無料）
3月でもツアー客などが多く、１階は込み合っていたので２階の有料席に。テラスにも出て海の様子が見られるのでお勧めです。

水牛車にゆっくりと揺られて由布島へ。ゆったりとした歩みで透き通った海を渡る、沖縄時間を味わいました。子供は今回の旅行で水牛車が一番楽しかったと言っています。
由布島では９０分散策ですが、食事時間も入っているので、案外とゆっくりとはできません。２時間くらいあればもう少し島全部を回って歩けるのに、と残念でした。
綺麗な海岸もあるので、サンダル・足を洗う用の水・タオルを持っていくとお子様も楽しめると思います。
ジェラート屋さんもあり、泡盛や島レモン、黒砂糖漬けラムレーズン味などがありとても美味しかったです。
秘密基地（ツリーハウス風のもの、ブランコなど）、水牛への餌やり、蝶もたくさん飛んでいて、とても楽しかったです。

西表島のマングローブは、解説付きでさらに楽しめました。本当に一体マングローブだらけで石垣島にもマングローブはありますが、圧巻です。

自分で島にも行けますが、ツアーであちこち連れて行ってくださったので効率的に回ることができ、助かりました。特に待ち時間もなくスムーズでした。

由布島での食事（弁当）は子供は現地で注文です。カレーや沖縄そばなどがあり、食べるものには困りませんが、お子様ランチのようなものはなかったと思います。
お弁当は沖縄料理の詰め合わせで、初めて食べるものも多く、おいしくいただきました。天ぷらなど冷めているものもありますが、団体客のお弁当なので十分だと思います。

帰りのホテルまでのバスは、ターミナルに到着してから1時間後の出発だったためタクシーで帰宅。ターミナル付近はお店もたくさんあるので散策して帰るのもいいと思います。帰りのバス希望の人は、当日にカウンターで申し込めばよいようです。

楽しい旅行の思い出をありがとうございました。

It was a very satisfying tour that allowed us to fully enjoy the islands in just one day, departing from and returning to Ishigaki Island. The perfect schedule was clearly designed to be manageable, making it possible to experience everything we wanted to see and do.

石垣島出発、帰着で、1日で離島を満喫できた内容で、大満足のツアーでした。
明らかに個人では困難であろう無理のない完璧なタイムスケジュールで、見たいもの、やりたいことを全て満喫できました。

The weather in February tends to be cloudy, and on the day we participated, the sky was overcast and it started to drizzle in the afternoon.

Kayaking on the Miyara River was a relaxing experience as we enjoyed forest bathing in the mangrove forest with the SAP experience group. The snorkeling focused on the coral reefs, and we occasionally spotted some fish.

We received a message the day before, so we couldn't go to the Blue Cave.

For kayaking, there was water accumulating in the seating area, so I recommend wearing clothes that can get wet. Also, since you'll be changing footwear for both activities, beach sandals are better than shoes.

2月の天気は曇りの日が多いらしく、私たちが参加した日はどんよりした空模様で午後は小雨も降ってきました。
宮良川でのカヤックはSAP体験の方と一緒にのんびりマングローブ林で森林浴を楽しみました。シュノーケリングはサンゴ礁がメインで時々魚が見える感じでした。
前日に連絡があり、青の洞窟へは行けませんでした。

カヤックは座るところに水が溜まっていたので、お尻が濡れても大丈夫な服装で行かれることをお勧めします。あとどちらも履き替えるので靴ではなくビーチサンダルの方が良いです。

I have previously cycled around both Lake Biwa and Awaji Island, and I believe that those who have completed these rides should have no significant physical issues with the Jomon Sugi tour. The guide provides appropriate breaks and explanations of the sights along the way, so you can consider it comparable to a cycling event that is about 100 km long with a decent elevation gain.

However, if you usually only exercise on a road bike, please be cautious on the return from Jomon Sugi. On a road bike, you typically ride on paved roads, so as long as you are straddling and braking properly on descents, you should be fine. But on the Jomon Sugi tour, you will need to descend rocky areas and stairs on foot, which puts significant strain on your ankles, knees, and hips for about four hours. (I experienced pain on the outside of my knee, which I believe is what is referred to as runner's knee.)

As a precaution, I recommend strengthening your core and using trekking poles to find a descent method that minimizes strain on your body before participating in the tour. I used trekking poles for the first time on the day of the tour, but since I wasn't accustomed to them, there were moments when they actually added to my burden.

Regarding meals, I requested two bento boxes (two rice balls, fried chicken, sausage, fish, and pickles) as part of the tour options for breakfast and lunch. The contents were almost the same for both meals. In addition to the bento, I brought two pieces of bite-sized yokan, received some salt candies and gummies from other participants, and had oral rehydration gel to prevent muscle cramps, which may have been more than I needed.

For those who have cycled for ten hours in a day, I think less food than that would be sufficient. As for drinks, I brought two 600 ml bottles of barley tea, but I ended up only needing one and refilled with spring water along the way, making one bottle completely unnecessary.

In early March, the estimated temperature around Jomon Sugi was in the low single digits, with cloudy weather and occasional rain, including some hail. Depending on the season, hydration needs can vary greatly, so if you find that spring water is sufficient, you might consider refilling along the way to reduce your load.

Regarding restroom facilities, I took care of my needs before departure and sipped water every few minutes, which was enough to make it to the toilets set up along the route. This can vary greatly depending on the season and individual needs, so please use this as a reference. Just in case, I brought one portable toilet for emergencies and five portable urinals I bought at a 100 yen shop, but I brought too many urinals.

I hope this lengthy account is helpful for those considering participation.

自分は過去にロードバイクで琵琶湖、淡路島共に一周の経験がありますが、縄文杉ツアーはビワイチ、アワイチをこなせた方は体力的にはほぼ問題無いかと思います。
ガイドさんによる適度な休憩、道中の見所の説明等があるので、１００km程度で、それなりの獲得標高になる〇〇ロングライドと名前の付く自転車イベントと同等程度と考えていいでしょう。
ただ普段の運動がロードバイクのみという方は、縄文杉からの帰りには気を付けて下さい。
ロードバイクだと基本舗装路の為、下りは跨がって、適切にブレーキをかけていれば何とかなりますが、縄文杉ツアーの場合、岩場や階段を自分の足で降りるという行為が発生します。
どういう事かというと、ロードバイクの下りではほとんど問題無い足首、膝、股関節に非常に負荷がかかる状況が約４時間続く事となります。(自分は膝の外側に痛みが出てしまいました。おそらくランナー膝と呼ばれるものだと思います)
対策としては、体幹を鍛える、トレッキングポールを使用する等、体に負担のかからない自分に合った段差の下り方を、ツアー参加前に試して見たほうがいいかと思います。
トレッキングポールを当日初めて自分は使いましたが、使い慣れていないせいで、かえって負担になる場面もあったように思います。
あと食事についてですが、自分はツアーのオプションで朝昼のお弁当(おにぎり２個、からあげ、ウインナー、魚、漬物)２食分をお願いしました。(朝昼共内容はほぼ同じ)
お弁当プラス持参した一口羊羹２個、他の参加者の方から頂いた塩飴、グミと、筋肉の攣り対策の為持っていった経口補水ゼリーで自分は少し補給が多かったかもという感じでした。
自転車で一日十時間走った事がある方は、その時より少な目の補給食で十分かと思います。
また飲み物ですが、600mlのペットボトルの麦茶を二本持って行きましたが、結局一本と道中で湧き水を一本分補給した程度で十分間に合い、一本は完全にデッドウェイトとなってしまいました。
3月上旬、縄文杉あたりの気温推定一桁前半、曇時々雨、途中あられという天候でしたが、季節によって水分補給の状況は大きく変わるかと思いますが、湧き水で十分な方は道中で給水し、荷物の負荷を少しでも減らす事を検討してもいいかもしれません。
その他トイレ事情ですが、出発前に大を済ませ、道中の給水を一口ずつ、数十分おきでしていましたが、それで道中に設置されているトイレで十分間に合いました。
季節や個人差が大きいものなので参考程度にして下さい。
念の為、簡易トイレ用の携帯トイレ一つ、１００円ショップで買った小便用の携帯トイレ五つ持って行きましたが、小便用は持っていき過ぎでした。

長々と書かせて頂きましたが、参加しようと思っている方の参考になれば幸いかと思います。

I was taken on a tour by a veteran guide, and I was very satisfied with the experience✨ Thank you!!

ベテランガイドさんに連れてっていただいて、とっても満足なツアーでした✨
ありがとうございました！！
