According to local people in Chi Lang Nam, there are many interesting legends about the stork island. In the past, this area was sunken and the island was formed in the 15th century after the dyke of the Red River collapsed because of a big flood. Gradually, it became the home of different varieties of storks, herons and birds.                                            
At present, there are about 16,000 storks of six species, such as white storks, fiery storks, cattle egrets, and grey storks. There are also 6,000 herons on the island. Many rare and valuable birds can be found here such as pelicans or teals. Every year, in September of the lunar calendar when the north-east wind blows, thousands of storks, herons and birds from other places fly to the island. They often stay there until April of the following year. Therefore, the island becomes a destination of tourists and an environmental education centre is there to help raise awareness of environmental protection.

The best time to visit Chi Lang Nam Stork Island is at sunrise or sunset. At these times, visitors will have a chance to behold a beautiful painting with white storks and herons flocking out of and into the lake. Tourists will enjoy a spacious and greenish space with the peaceful landscape of a rural area. It is wonderful to mingle with nature and be away from our busy lives.
