Nong Han, the largest natural lake of northeast Thailand, is the main source of water for irrigation in agriculture and for use of the villagers living in the locality. Declared a wetland of national importance, Nong Han is also known as “Thalay Bua Daeng”, or the Red Lotus Sea, where water lilies blossom between October and March of every year. Starting from October, the water lilies begin to put out new leaves, and flower buds emerge before fully blooming between December and February and withering and falling in March. The optimum time to enjoy the beauty of the flower-filled lake is from the early morning until 11 am when visitors can enjoy the breathtaking picture of endless water lilies blossoming and blanketing all over the lake, from which the name Red Lotus Sea is derived.
