龍河洞：擁有一億年歷史的鐘乳石洞，內部投射超逼真影片效果立體又震撼，是探險旅遊的最佳選擇，位於日本高知縣
【龍河洞：日本高知縣的 1 億 7500 萬年歷史遺跡，代表性鐘乳洞，享有國家天然記念物與史跡之名】
龍河洞是日本高知縣的代表性鐘乳洞之一，被列為日本國家天然記念物與史跡。洞內全長 4 公里，其中 1 公里開放給一般遊客參觀。在這個高達 1 億 7500 萬年的歷史遺跡中，遊客可以見識到神奇的鐘乳石結構以及珍貴的古跡。
龍河洞內有許多形狀獨特的鐘乳石，有長 10 公尺的、像聖母馬利亞、佛祖的、像瀑布的如玉簾瀑布、裏見瀑布、音無瀑布、飛龍瀑布等等，其中命名為天降石的鍾乳石高達 11 公尺，是龍河洞內最大的鍾乳石。此外，龍河洞內還有一個非常珍貴的古跡 - 神之壺，是二千年前住在洞內的祖先遺留下來的生活用品。石灰地形的作用，讓土器的三分之一已被埋入鍾乳石中，成為世界唯一的考古學珍貴資料，並且是龍河洞第一級寶物。
在接近出口處，設有光雕投影，洞內的鐘乳石壁化為屏幕，上映了精彩的動畫，當中意味了龍河洞的悠久歷史。投影畫面與洞內鐘乳石完美地結合，動畫充份利用鐘乳石的線條來製造立體感，為觀眾帶來穿梭於虛擬與現實之間的感覺，非常厲害。
對於喜歡刺激和冒險的遊客，龍河洞還提供了冒險路線，有工作人員帶領。遊走時有時要爬行前進、有時要爬樓梯及抓繩子，更可以手摸腳踏岩石與鍾乳石，當中有一部份行程全部人都會關掉頭燈體驗黑暗。這是一個讓你更深入了解龍河洞、感受冒險與刺激的經驗。記得要早一天跟龍河洞保存會預約冒險路線。
在龍河洞的遊覽中，您可以見識到日本古老文明的瑰寶，並且享受到大自然的鬼斧神工帶來的美景。這是一個讓您身心放鬆、感受大自然魅力的好地方
Dragon Cave: A 175 million-year-old historical site in Kochi Prefecture, Japan, renowned for its unique stalactite formations and designated as a National Natural Monument and Historic Site.
Dragon Cave is one of the most representative stalactite caves in Kochi Prefecture, Japan, designated as a National Natural Monument and Historic Site. The cave is 4 kilometers long, with 1 kilometer open for public viewing. Visitors can witness the magical stalactite structures and precious ancient relics in this 175 million-year-old historical site.
Inside Dragon Cave, there are many unique stalactite formations, such as the 10-meter-long ones resembling the Virgin Mary, Buddha, and waterfalls like the Jade Curtain, Urami, Oto-nashi, and Hiryu. Among them, the largest stalactite, named "Heavenly Stone," is 11 meters tall, making it the biggest stalactite in the cave. Additionally, Dragon Cave houses a precious ancient relic called "Kami no Tsubo," a household item left by our ancestors who lived in the cave 2,000 years ago. Thanks to the limestone formation, one-third of the pottery is buried in the stalactite, making it the only archaeological treasure in the world and the first-class treasure of Dragon Cave.
Near the exit, there is a light projection showcasing stunning animations projected onto the stalactite walls, depicting the long history of Dragon Cave. The animation fully utilizes the stalactites' lines to create a three-dimensional effect, giving the audience a sense of traveling between virtual and reality.
For adventurous visitors, Dragon Cave offers an adventure route led by staff. During the tour, visitors may have to crawl forward or climb stairs and ropes while touching rocks and stalactites. There is also a part of the tour where everyone turns off their lights to experience complete darkness. This is an opportunity to gain a deeper understanding of Dragon Cave and experience adventure and excitement. Remember to reserve the adventure route with the Dragon Cave Preservation Society one day in advance.
During the tour of Dragon Cave, visitors can witness the treasures of Japan's ancient civilization and enjoy the beautiful scenery created by nature's craftsmanship. It is a perfect place for visitors to relax and experience the allure of nature.
