Things to do in Seoul in April

Jinhae Gunhangje Cherry Blossom Festival

One of the top attractions in Seoul in April is the Jinhae Gunhangje Cherry Blossom Festival. Over two million visitors come to Seoul every year to watch the blossoms, which typically happen between late March and early April.  There are numerous places throughout Seoul to admire the blossoms, which almost appear to be fake at first glance.  The cherry blossom festival also includes a cultural Victory Parade, reenacting the Joseon victory march after the Imjin War.  The Yeojwacheon Starlight Festival paints the cherry blossoms with laser lights and traditional illuminations, and nearby there is an impressive fireworks display that takes place the first week of April.

Biking the Han River

April is finally warm enough to enjoy outdoor activities.  A good, easy tour is bicycling the Han River.  April is an especially beautiful time to do this activity, as the flowers and trees start to bloom.  The ride is 15km long and takes approximately three hours.  It starts at the Yeouinaru station and ends at Yeouido Park.  There are several bike shops at the beginning where you can rent bicycles specifically for this ride.  The ride will take you past beautifully manicured island parks, cafes, a marina, and traditional Korean gardens.

Lotus Lantern Festival
