What kind of travel becomes especially heavy in South Korea during the Chuseok holiday period?

Intercity travel becomes especially heavy in South Korea during the Chuseok holiday period.

Chuseok is a major family holiday, so many people leave large cities and travel to hometowns or relatives’ homes. Roads, railways, buses, and domestic flights can become heavily crowded as millions of people make similar journeys around the same dates.

The movement is often described as a national travel rush. Families may reserve tickets early, travel at less busy times, or use real-time traffic information. The pattern is also connected with South Korea’s concentrated urban population and extensive transport network.

Intercity travel means movement between cities or towns within the country. It is different from international tourism, which is not the defining travel pattern of Chuseok.
