Seonyudo (meaning “an island where Taoist hermits play”) Park was the nation’s first recycling park. It was created using the old sewage treatment facilities on Seonyudo Islet. From 1978 to 2000, the park-site was used as a sewage treatment plant to provide tap water to the southwestern part of Seoul. Seoul Metropolitan Government closed the plant down in Nov. 2000 and spent 16.4 billion won to turn it into a park, which opened in 2004. The park features the Hangang Exhibition Hall, which briefs visitors about the history of Hangang and its flora and fauna. The Water Purification Basin, the Garden of Time and the Ecological Water Playground are also all popular destinations of the park. Once you reach the park entrance you should then cross the footbridge called “Seonyugyo” (Seonyu Bridge) to get to the park. This wooden bridge, which was the first footbridge ever built to connect an islet on the river to the land, was constructed as a joint project with France. In the evening, lights projected onto the bridge produce beautiful reflections on the river’s surface explaining why this park is especially popular with couples. The small gardens of this park feature various seasonal flowers and plants all year long.
