Deep inside the tropical rainforests of the Kerinci Seblat National Park, an exceptional beauty radiates from an enchanting lake with water as clear as the purest crystal. The lake is so transparent that it earned the local name of Lake Kaco, or in English simply meaning the Glass Lake. The lake is located at Sempur Village, Kerinci Regency, the province of Jambi.
Lake Kaco is situated approximately 1,289 meters above sea level and measures about 30 m by 30 m in total area covered. What makes this Lake exceptional is its crystal clear blue water which contrasts beautifully with the dark green foliage of the surrounding trees. There is no actual account of the lake’s depth, however one can definitely observe thousands of endemic Semah fish swimming at various depths.
As the sun sets over the horizon and darkness takes over, Lake Kaco presents its magical wonders and radiates bright gleaming lights, especially at full moon. This beautiful phenomenna attracts many visitors to camp here during full moon to experience one of nature's greatest features.
A number of scientists and researchers have conducted scientific researches here to uncover the mystifying phenomena of Lake Kaco, as to its luminous blue water and its unidentified depth. Researches who dived into the lake said that most of the oxygen in their tanks was already depleted before they reached the lake's floor.
While science has yet to find the answer to this mystery, local legend and folklore may provide a bit of explanation on the wonders of lake Kaco.
Legend has it that once upon a time a beautiful princess lived by the lake and attracted all young men in the area to wed her. Obsessed by her beauty, these infatuated youths gave diamonds and all kinds of precious gemstones and other gold pieces to Raja Gagak, father of the princess.
However, obsessed by greed, Raja Gagak violated his own daughter and drowned the princess into the lake together with all diamonds and gemstones given to him.
The myth concludes that the glowing blue color of the lake’s water comes from the sparkling diamonds submerged at the bottom of the lake. While the enchanting ambience and the unexplainable beauty of the lake are radiated by the the princess's own aura.
