Kaptai Lake: This large man made lake of Bangladesh spanning over an area of approximately 11000km2, was created as a reservoir when the Kaptai dam was built during the 1960s. The lake was created by flooding valleys and plain lands between numerous hills. This created a picturesque view as forested hills and plateaus rise from beneath the water. How to go : The government run tourism corporation and private operators offer Kaptai Lake Cruise Tours, which is worth of it. Other scenic spots are also accessible through the waterways.
