Bandarban, the mysterious and beautiful region of Bangladesh. What if I tell you the dragons are real?What if I tell you water can change its own color?? Both of them are unbelievable, right?As mentioned before, water can change its own color!! Surely, Water cannot change its own color– but when you will visit this insanely beautiful lake you would definitely think water can change its own color!! The simple science behind this color variation is just the surroundings depending on the sunlight, clouds, and humidity which help to create an illusion for our eyes.The lake is 2400 above sea level, and it covers 15.1 acres area and the depth is about 150 meters (502 feet). And there is no water source around this lake. The lake is bounded by three sides by mountains. Though there is not enough waterfall near the peaks it’s just a mysterious act of nature the mountain’s peak always totter with water!!
