Seoul International Fireworks Festival
One of the city’s flashiest festivals is the Seoul International Fireworks Festival, held every October. Teams of pyrotechnicians from as far away as Sweden join forces to create an explosive extravaganza that lights up the sky over the Han River. Warning: It gets very crowded. Arrive at the park way before dark if you expect to stake out a prime viewing spot, or book ahead at one of the many top-floor restaurants or bars, such as Mariposa or VVertigo, for the best seats in Yeouido.
