Located on the northern side of Songhua River and in downtown Harbin City, Sun Island is the only floodplain wetland ecology in the city's center in China. In the 1980s, the song on the Sun Island by Zheng Xulan spread the name of the island far and wide.
Influenced by the monsoon climate, there is a distinction between the sceneries of different seasons on Sun Island. As the first 5A national scenic area in Heilongjiang Province, the island is the pride of the locals and the pursuit of visitors. In terms of fun, Sun Island is considered to be the paradise for ice and snow festival tour; meanwhile it is also the best natural summer venue in Harbin. When winter comes, the island is covered with snow, making it a best chance to see the Snow Carving Festival in this island.
