Kaptai Upazila: History
The name of the Kaptai was derived from the Tripuri word "Kaptetoima". It is said that in the past, the river was wild and full of tropical flora and fauna. Large quantities and several varieties of canes could be found along the river bank that flows from the south, upper ridge. The river reaches its estuary at the Kainsa Khyong (Karnafuli River).
