- The best season to travel to Ella Nil Diya Pokuna is during the dry and pleasant months from January to April. During this time, Ella has less rainfall, clearer skies, and comfortable temperatures, making it easier and safer to explore the underground steps leading to the pond. The surrounding scenery is also beautiful, which adds to the overall travel experience.
- Another suitable period is June to August, when rain is moderate but not continuous. It is best to avoid October to December, as this is the main monsoon season in the Ella region, bringing heavy rain that can make paths slippery and travel difficult. For the best visit, go early in the morning or during the daytime, when visibility is good and conditions are safer inside the underground structure.
