Our pick for a first trip is five days in Seoul, or eight to ten days to include Busan or Jeju. With two weeks, add Gyeongju and a slower pace. Start with the South Korea travel guide to choose your route.
Which month should you pick?
Our pick is October. Seoul's average low and high are 10.6–20.2°C (51–68°F), with about 52mm of rain compared with 414mm in July. April is another mild option. These are 1991–2020 climate averages, not a forecast; use the Seoul guide to plan your stay.
Do you need a visa or a K-ETA?
Most visitors need one form rather than two. Nationals of eligible visa-free countries and regions are exempt from the K-ETA until 31 December 2026, and not holding a K-ETA is exactly what makes the free e-Arrival Card mandatory, submitted in the three days before you arrive. Holding a K-ETA exempts you from the card, and so does a Korean residence card. The official e-Arrival Card guide lists who must declare, the official K-ETA site holds the country list, and K-ETA or e-Arrival Card works through which applies to you.
What does getting around cost?
A Seoul subway ride starts at KRW 1,550 (Korean won) on a transit card. Busan's subway costs KRW 1,600 or 1,800 depending on the section. A T-money card works in both cities. Read the Seoul fare and transfer guide for the details.
