1100 Hill Wetland is a representative mountain wetland formed in the Hallasan highlands, with more than 16 wetlands distributed discontinuously. A wetland protection area was established along these wetlands in 2009, and it was registered as a Ramsar wetland in the same year. Information about the animals and vegetation environment of the 1100 Hill Wetland are installed throughout the trail, providing information about the wetland. Here, falcons and wild animals, which are classified as endangered species that only live on Hallasan Mountain, exist, and the water accumulated in the low areas of the wetland serves as a drinking water source for wild animals. There is a natural ecological trail made of trees within the wetland, so you can view the wetland while walking.
