Yeouido Park is a large recreational area located on Yeouido Island in the central part of Seoul. It was once originally covered with black asphalt, and people frequented the place for bicycling and roller-skating. The construction began in 1997, and opened officially in February 1999. It is now the place where many people in the city come to rest and enjoy strolling around, play sports, and cultural events. The park is divided into theme-based sections: the Traditional Korean Forest, Grass Square, Culture Square, and Nature’s Ecosystem Forest. In the Traditional Korean Forest, only traditional Korean trees are planted, and it has a pond and an octagonal pavilion, with a trail walk that completes the feel of an elegant Korean garden. Grass Square has a low hill, with grass field and various trails, and nearby there are evergreens and deciduous trees to reflect the changing of the seasons. Many performances and events are held at the Cultural Square, and because there are many zelkova trees lined up nearby, it is a great place to rest. One particular part of the park that is most enjoyed is the Nature’s Ecosystem Forest – it is where you can observe nature and learn from an ecologically sensitive pond and forest, right in the middle of the city. Composed of a swamp area, waterline area, grassland area, and a forest, you can observe various kinds of life forms living in these areas. One of the must-see areas is the Yunjunro Street, behind the National Assembly Building. This place is famous for having the loveliest cherry blossom street in Seoul. Cherry blossom trees, 30 to 40 years old, line up for about 6km, and is very popular in the spring.
