From the Travel Diaries of Aitken Spence Travels team – Nil Diya Pokuna

The Nil Diya Pokuna is an adventure to be taken by the adventurous and the daring souls visiting Sri Lanka. If you are in Ella and want to explore something unique and not visited by many, do take this excursion and your efforts are not going to be in vain.

Nil Diya Pokuna is an underwater pond situated in a cave or a tunnel complex in Ella which is believed to have been built by king Ravana. The pond lies 80 meters deep inside a mountain cave in Karandagolla. The cave can be accessed via two independent entrances, of which the better-known one is situated in a forest reservation in the area. A villager then discovered a second entrance on a private property. The cave has a rabbit hole entrance through which the pond can be reached. Nil Diya Pokuna is a place to be explored by the adventurous and caution should be taken during this journey. The water of the pond is crystal clear and gives a blue tinge of color when it reflects with light.
