Yeouido is a large island in the Han River in Seoul, South Korea. It is Seoul's main business and investment banking district. The island is located in the Yeongdeungpo-gu district of Seoul, and contains the National Assembly Building, the 63 Building, and the headquarters of LG, KBS, and MBC to name a few.
But what I love about this island is the public parks within the island, most notably the Han River Public Park and the Yeouido Park. I was unfortunate to be unable to see the cherry blossoms bloom in mid-April but if you're lucky enough, it is truly beautiful. I spent many days here, mostly because it was close to home and on hot afternoons, relaxing by the river is very refreshing and cool.
I rented bikes there and rode along the Han River which was also very relaxing and affordable to be honest (about 3,000KWN/hr). You can also board the Han River cruise here that sales along the river all the way to Jamsil.Of all the places I visited in Seoul, this is in my top three favourite spots especially on a hot summer day and you're looking to escape the heat and humidity. There are also tandem bikes available for rent for couples, a great family park for picnics and barbecues, and wading pools in the fountains are especially busy on weekends.
