Sri Lanka is home to many hidden wonders, and among them is the enchanting Nil Diya Pokuna, an underground natural pond nestled deep within the Karandagolla cave system near Ella. Translating to “Blue Water Pond” in Sinhalese, Nil Diya Pokuna captivates adventurers with its crystal-clear blue waters and serene atmosphere, making it one of the most unique and mysterious destinations in the country.
In this comprehensive guide, we’ll explore everything you need to know about visiting Nil Diya Pokuna, from the challenging trek to the caves, the fascinating history behind this mystical site, and why it’s a must-visit for thrill-seekers.
What is Nil Diya Pokuna?
Nil Diya Pokuna is a natural underground pond located approximately 800 meters beneath the surface, deep inside a cave system in the Karandagolla region. The pond is renowned for its striking blue hue, which gives the site its name. The stunningly clear waters of the pool reflect a distinct blue glow, creating an almost otherworldly atmosphere.
The cave system surrounding Nil Diya Pokuna is a labyrinth of narrow passageways and chambers, making the journey to the pond an adventurous and challenging experience. Visitors must navigate through dark, confined spaces and slippery, muddy terrain to reach the pool, which lies at the heart of the cave system.
What makes Nil Diya Pokuna even more captivating is its connection to Sri Lankan folklore, as well as its status as one of the only known underwater cave systems in Sri Lanka.
The History and Folklore of Nil Diya Pokuna
Nil Diya Pokuna was first discovered in 2003 by a local explorer, but its history stretches much further back, woven into the fabric of Sri Lanka’s ancient mythology. The caves surrounding the pond are said to be part of an underground tunnel system that belonged to the legendary King Ravana, a key figure in the Ramayana epic.
According to legend, King Ravana, who ruled over Sri Lanka thousands of years ago, used the cave system as a series of hideouts and strategic points during his reign. It’s said that the tunnels allowed his armies to move undetected beneath the surface, offering an element of secrecy in times of war. The caves are also linked to stories of King Ravana’s abductions and secret escape routes, making them an integral part of Sri Lanka’s rich mythological tapestry.
While much of this folklore remains unverified, the discovery of the Nil Diya Pokuna pond has certainly added to the intrigue surrounding these ancient tales. Locals and visitors alike are drawn to the site not only for its natural beauty but also for its historical and mythical significance.
The Cave System: A Challenging Journey
The cave system surrounding Nil Diya Pokuna is a vast network of narrow passageways and large chambers, offering an exhilarating and challenging adventure for those brave enough to explore it. The descent into the caves begins with a trek through the lush jungle, which leads to the cave’s entrance. From there, the journey becomes increasingly demanding, as visitors must navigate through confined spaces, slippery terrain, and muddy paths.
Equipped with helmets and headlights, adventurers make their way through dark tunnels, using ropes and ladders to traverse certain sections. The path can be physically demanding, requiring a good level of fitness and stamina. The narrow, claustrophobic spaces inside the caves can be challenging for even the most seasoned explorers, and the muddy conditions make footing difficult.
However, the effort is well worth it. Along the way, visitors are treated to stunning rock formations and expansive cavernous chambers. One such chamber, with its high ceiling and jagged rocks, evokes imagery of King Ravana’s underground hideouts, adding a mythical element to the journey.
Nil Diya Pokuna: The Blue Water Pond
After navigating through the cave system, adventurers are rewarded with the breathtaking sight of Nil Diya Pokuna itself. The pond’s crystal-clear waters reflect a mesmerizing blue glow, creating an ethereal atmosphere. The purity of the underground springs and the unique geological formations that surround the pond give it an otherworldly quality, making it feel like a hidden paradise.
The pond’s waters are exceptionally clear, allowing visitors to see deep into the depths. At its deepest point, the pond reaches a depth of 30 meters (100 feet), though during the rainy season, when water levels rise, the pond can become even deeper. The water temperature remains a steady 23°C (73°F), making it a comfortable spot for swimming.
Visitors can take a dip in the serene waters of Nil Diya Pokuna, enjoying a moment of tranquility after the physically demanding trek. Swimming in the pond is a unique experience, offering a sense of peace and solitude amidst the cave’s cool, dark surroundings. The enchanting blue glow of the water makes for an unforgettable backdrop, perfect for capturing memories.
Exploring the Underwater Cave System
Nil Diya Pokuna is not only a visual marvel but also a unique underwater cave system. Dharshan Jayewardene, the first person to dive into the pond, explored the underwater parts of the cave from 2017 to 2021, creating the first map of the underwater network. According to Jayewardene, the underwater cave system spans hundreds of square meters and reaches depths of up to 30 meters.
What makes the underwater cave system truly remarkable is its vastness. Jayewardene described it as a “massive space” with no visible living beings in the water. This sense of emptiness, combined with the crystal-clear waters, adds to the mysterious and otherworldly feel of the cave system.
For experienced divers, the underwater caves offer an exciting challenge. However, diving in Nil Diya Pokuna requires proper equipment and should only be attempted by skilled professionals. The underwater environment is both beautiful and treacherous, with narrow passageways and deep chambers that can be difficult to navigate.
The Trek to Nil Diya Pokuna: What to Expect
Visiting Nil Diya Pokuna is an adventure in itself. The trek begins in the village of Karandagolla, located near Ella. From there, visitors embark on a hike through the dense jungle, leading to the entrance of the cave system. The trek can be physically demanding, with steep inclines, uneven terrain, and slippery paths.
The cave’s entrance is marked by a narrow opening, through which visitors must descend to begin their underground journey. Equipped with helmets and headlights, visitors make their way through the dark, confined spaces of the cave system, using ropes and ladders to traverse certain sections.
The trek is not for the faint of heart. It involves navigating through tight spaces, climbing over rocks, and wading through mud. The conditions inside the cave can be challenging, with low ceilings, slippery surfaces, and limited visibility.
However, for those who enjoy a physical challenge, the trek to Nil Diya Pokuna offers an exhilarating and rewarding experience. The sense of adventure, combined with the breathtaking beauty of the blue water pond, makes it a must-visit destination for thrill-seekers.
