When the weather gets warm, locals flock to Yeouido Park to cool down by the breezy Han River. The park becomes even more of a magnet from March through October, when it hosts the Seoul Bamdokkaebi Night Market on Friday and Saturday evenings. In addition to craft vendors, there’s a Food Truck Zone where dozens of vehicles line up to sell sweet and savory treats from around the world. Once you’ve selected your dinner, spread out a blanket on the lawn and enjoy a picnic alongside live music and entertainment. The surrounding roads are jammed with traffic on market nights, so plan to arrive by subway and disembark at Yeouinaru Station.
