Upo Marsh

Considered to be the largest inland wetland in Korea, Upo March is a must-visit site for all tourists and one of the best free tourist attractions in South Korea. It is said that this land was formed over almost 140 million years ago and it is home to about 1500 species of plants and animals too. Some of these animals are, however, currently endangered. You can also spot a few migratory birds here which are found to be flying low as you walk or bike through the land. This surely tops the list of good places to visit in South Korea
