Deep beneath the misty hills of Ella lies one of Sri Lanka’s most extraordinary and challenging adventures – Nil Diya Pokuna, the legendary “Blue Water Pond” that has captured the imagination of thrill-seekers and nature lovers from around the world. This isn’t your typical tourist attraction; it’s a journey into the heart of the earth that combines physical challenge, natural wonder, and ancient legend into one unforgettable underground expedition.
What Makes Nil Diya Pokuna So Special?
Nil Diya Pokuna, which translates to “Blue Water Pond” in Sinhalese, is a captivating natural site located deep within a cave system near Ella in Sri Lanka. Situated 80 meters underground in the mountainous area of Karandagolla, this pond gets its name from the unique blue hue of its waters.
But this isn’t just any underground pool – it’s the most secret underground water pool in Sri Lanka, a pristine natural wonder that requires courage, determination, and a true spirit of adventure to reach. The pool is famed for its crystal-clear water, which exhibits a mesmerizing blue glow due to the cave’s geological formations and the purity of the underground springs.
What sets Nil Diya Pokuna apart from other natural attractions is the incredible journey required to reach it. The journey begins with a steep 300m descent into a cave that unfolds into an expansive underground complex. This isn’t a simple walk in the park – it’s a genuine caving expedition that challenges both your physical limits and your comfort zone.
The Legendary Connection to King Ravana
Nil Diya Pokuna was discovered in 2003 by a local explorer who now serves as a guide. While a recent addition to Sri Lanka’s natural attractions, this site quickly became enveloped in the tapestry of local folklore.
The cave system has become deeply intertwined with one of Sri Lanka’s most famous legends. According to these tales, King Ravana is said to have used this cave system. The folklore says that these caves were part of Ravana’s extensive network of tunnels and hideouts, possibly used for strategic purposes during his reign. Some locals think that Ravana hid an army of several thousand in the underground cave system during a war.
Legend has it that King Ravana, known for his mythical feats, may have played a role in the creation of Nil Diya Pokuna. The cave exudes an architectural presence, sparking intrigue about its origins. Whether you believe in the legends or not, there’s something undeniably mystical about descending into these ancient chambers that have remained hidden for centuries.
Your Underground Adventure: What to Expect
The Entrance: Where Adventure Begins
The journey starts with a walk through a small jungle, immersing visitors in the greenery that paves the way to the cave’s entrance. Upon arriving at the cave entrance, adventurers are greeted with a seemingly small opening, a gateway to the underground marvels.
Don’t let the modest entrance fool you – you’re about to embark on one of the most challenging and rewarding adventures Sri Lanka has to offer. Equipped with helmets and headlights for safety, visitors begin their descent. The first part of this descent is navigated using ropes.
Descending into the Depths
The real adventure begins with your descent into the darkness. The journey continues with a climb down through another, smaller hole, this time aided by a ladder. This descent marks the entry into a world unlike any other – an underground realm of darkness and mystery.
As you venture deeper, the environment becomes increasingly challenging. Inside, the cave transforms into a network of narrow tunnels where the paths are often dark and confined. In certain sections, the cave’s limited space challenges visitors to stoop or even crawl, making the journey physically engaging and adventurous.
Navigating the Underground Labyrinth
As the journey progresses deeper into the cave, the environment becomes more challenging. The path can be muddy and slippery, a reminder of the untamed nature of this underground world. The absence of safety railings along the path emphasizes the need for cautious navigation. Visitors need to be mindful of their steps, especially in areas where the cave features jagged rocks and dangerous drops.
But the challenges are worth every step. At one point, the path opens into a massive cave chamber with a high ceiling, revealing stunning rock formations. Aside from its natural beauty, this part of the cave brings to life the folklore of King Ravana’s army, adding a layer of mythical intrigue.
The Magnificent Underground Cave System
Also known as the Karandagolla Cave, Nil Diya Pokuna boasts a unique tunnel and an underground cave with a natural blue pond at its heart. This isn’t just a single cavern – it’s an extensive network that continues to reveal new secrets.
Divers have explored the pond’s depths, discovering two additional tunnels branching off its base. The interconnectedness of this subterranean system suggests a connection to the external environment, adding to the intrigue. The fact that parts of this cave system remain unexplored adds an element of mystery that captivates every visitor.
As both air and water remain fresh within the tunnel complex, the connection to the outer environment is apparent. This natural ventilation system ensures that the cave remains livable and breathable, even at significant depths underground.
The Breathtaking Blue Water Pond
After navigating approximately 1 kilometer through challenging underground terrain, you’ll finally reach the crown jewel of this expedition. The journey culminates at the Nil Diya Pokuna Pool. After navigating the challenging, dark pathways of the cave, arriving at the pool feels like discovering a hidden treasure.
The pond, aptly named Nil Diya Pokuna, owes its title to the striking blue hue that graces its surface. Nestled 52 meters deep within the tunnel complex, the pond is a testament to nature’s artistry. The surrounding cavern, with a soaring ceiling of up to 100 feet, adds to the grandeur of this hidden gem.
The visual impact is absolutely stunning. The pool’s remarkable blue glow creates a stunning visual effect that’s both serene and mesmerizing. The light reflecting off the water enhances this effect, making the pool not just a sight to behold but a truly enchanting experience.
The pond’s crystal-clear waters reflect a mesmerizing blue tinge when touched by light. The ethereal beauty of Nil Diya Pokuna leaves visitors awe-struck, as they witness a natural wonder hidden beneath the surface of the earth.
Swimming in Paradise
This serene spot offers a much-needed rest from the adventurous journey. Visitors find themselves in a tranquil haven, a stark contrast to the confining darkness of the cave tunnels. The pool provides a peaceful setting where one can relax, soak in the beauty of nature, and perhaps take a refreshing swim.
The opportunity to swim in this pristine underground pool is something truly special – imagine floating in crystal-clear blue water surrounded by towering cave walls, knowing that you’re one of the few people who have ever experienced this hidden wonder.
Is This Adventure Right for You?
Visiting Nil Diya Pokuna is not an adventure that is suitable for everyone. The journey to this remarkable natural wonder is as challenging as it is breathtaking. Let’s be honest about what this expedition requires.
Physical Requirements and Challenges
It involves traversing through the depths of a dark, confined cave. The paths inside the cave are narrow, uneven, and can be treacherous, with slippery sections, sharp drops, and jagged rocks, all without the aid of safety railings. This makes the trek particularly risky and demands good physical fitness and careful footing.
Due to its challenging nature, we advise against it for seniors or children. The physical exertion required, coupled with the potential hazards along the way, makes it unsuitable for those who may not have the agility or stamina to navigate the cave safely.
Mental Preparation
Also, the cave’s cramped and muddy conditions might be uncomfortable for those who are claustrophobic or prefer to stay clean and dry. This trip is only for people who love adventure and are not scared of small places in cave.
The Reward for the Brave
However, if you are aware of the potential risks and take precautions, you may find this journey exhilarating and a novel experience. For some, it is a unique and exhilarating experience. Also, the pool at the end of the journey is a remarkable reward.
Essential Safety Tips and Guidelines
It should also be noted that this is not regulated by the Sri Lanka Tourism Board or any such governing body. This makes following safety guidelines even more crucial:
