Insider timing tips

- •The monsoon season (July-August) brings heavy rain and humidity, making it less ideal for sightseeing, though prices may dip slightly.
- •Winter (December-February) is very cold but offers lower prices and fewer crowds, except around Christmas and Lunar New Year.
- •Shoulder months like March and November can offer a balance of decent weather and fewer tourists, but be prepared for more variable conditions.
- •Major Korean holidays like Seollal and Chuseok can see significant domestic travel, leading to crowded transportation hubs and some business closures.
