Động Gyokusendo - Kỳ quan thạch nhũ tráng lệ ở Okinawa (Nhật Bản) - Văn hóa xã hội - TTXVN

Nestled within the vibrant cultural park of Okinawa World in Nanjo City, Okinawa, lies a subterranean masterpiece that captivates the imagination: Gyokusendo Cave. Known locally as Động Ngọc Tuyền or "Jewel Spring Cave," this magnificent limestone cavern is not merely a geological formation but a living testament to the Earth's enduring artistry, sculpted over hundreds of millennia. It proudly holds the distinction of being one of Japan's largest and most visually stunning cave systems, and it is rightfully celebrated as one of the seven natural wonders of Okinawa.

A Journey into Earth's Ancient Heart: The Formation of Gyokusendo

The sheer scale and intricate beauty of Gyokusendo Cave are truly astounding. Stretching for over 5 kilometers, it presents an otherworldly landscape carved from the very bedrock of Okinawa. While the full extent of the cave system remains a subject of ongoing exploration, approximately 890 meters are meticulously maintained and illuminated, offering visitors a safe and awe-inspiring journey through its most spectacular sections.

The story of Gyokusendo began over 300,000 years ago, a timeline that dwarfs human history. This incredible subterranean world was forged through a painstaking process known as karstification. Rainwater, slightly acidic from absorbing carbon dioxide in the atmosphere and soil, seeped through cracks in the island's vast limestone deposits. Over countless millennia, this acidic water slowly dissolved the calcium carbonate, gradually enlarging fissures into vast chambers and intricate passages. As the water continued to drip, it left behind minute deposits of calcite, which, over eons, accumulated to form the myriad of stalactites, stalagmites, and other speleothems that adorn the cave today.

The Dazzling Array of Speleothems

Walking through Gyokusendo is like stepping into a natural art gallery. The cave boasts an astonishing collection of over a million stalactites and stalagmites, each a unique sculpture shaped by time and water. Visitors are treated to a visual feast of formations, including:

• Stalactites: Hanging like icicles from the cave ceiling, formed by mineral-rich water dripping downwards.
• Stalagmites: Rising from the cave floor, built up by the accumulation of mineral deposits from dripping water above.
• Columns: Formed when a stalactite and its corresponding stalagmite meet and fuse, creating towering pillars that connect floor to ceiling.
• Flowstones: Sheet-like deposits formed by water flowing over cave surfaces, creating draperies and cascades of mineral.
• Cave Pearls: Rare, spherical formations found in shallow pools, polished smooth by the constant agitation of water.

Some of the most famous formations within Gyokusendo have been given evocative names, such as "Dragon God's Pond," a mystical pool reflecting the cave's grandeur, and "The Great Hall," a vast chamber that truly emphasizes the cave's monumental scale. The subtle, yet strategically placed lighting enhances the natural colors of the mineral deposits, transforming the cave into a vibrant tapestry of gold, amber, and deep earth tones, often punctuated by the shimmering "Silver Stream" where water gently flows.

Okinawa World: A Gateway to Culture and Nature

Gyokusendo Cave is not a standalone attraction but forms the centerpiece of Okinawa World, a sprawling theme park dedicated to preserving and showcasing Okinawan culture, history, and natural beauty. This integrated approach allows visitors to seamlessly transition from the ancient geological wonders of the cave to the rich cultural tapestry of the Ryukyu Kingdom.

Beyond the cool depths of Gyokusendo, Okinawa World offers a diverse range of experiences:

• Kingdom Village: A recreation of a traditional Ryukyu village where visitors can try their hand at local crafts like glass blowing, pottery, and weaving, or witness captivating Eisa dance performances.
• Habu Park: An educational facility dedicated to the Habu snake, a venomous serpent native to Okinawa, offering insights into its biology and the island's unique ecosystem.
• Tropical Fruit Orchard: A lush garden showcasing the exotic fruits that thrive in Okinawa's subtropical climate.

This holistic environment ensures that a visit to Okinawa World is a comprehensive immersion, blending the thrill of natural exploration with a deep appreciation for the island's heritage. It's a place where the echoes of ancient geological processes meet the vibrant rhythms of Okinawan tradition.

Experiencing the Wonder: Tips for Visitors

A visit to Gyokusendo Cave is an unforgettable experience for travelers of all ages. The pathways are well-maintained, making it accessible for most visitors, though comfortable walking shoes are highly recommended due to the damp surfaces. The cave maintains a consistent, cool temperature year-round, offering a refreshing escape from Okinawa's tropical heat. The gentle sound of dripping water and the cool, moist air create a serene, almost meditative atmosphere, allowing one to truly connect with the Earth's ancient rhythms.

Photography is generally permitted, offering ample opportunities to capture the cave's breathtaking beauty. However, visitors are encouraged to be mindful of flash photography, as it can be disruptive to other guests and the delicate cave environment. Taking a moment to simply observe and absorb the grandeur without the lens can be just as rewarding.

Okinawa's Natural Treasures: Beyond Gyokusendo

Gyokusendo's designation as one of Okinawa's seven natural wonders highlights the island's incredible biodiversity and geological significance. While the exact list of these "seven wonders" can vary, they generally encompass sites that showcase Okinawa's unique natural heritage, from its pristine emerald beaches and vibrant coral reefs to its lush subtropical forests and dramatic sea cliffs. These wonders collectively underscore the importance of conservation efforts to protect these irreplaceable natural assets for future generations.

In conclusion, Gyokusendo Cave is more than just a tourist attraction; it is a profound natural monument, a silent chronicler of geological time, and a dazzling display of Earth's creative power. Its intricate formations, vast chambers, and ancient history make it an essential stop for anyone exploring the enchanting island of Okinawa, offering a unique blend of adventure, education, and unparalleled natural beauty.
