South Korea travel guide: what to know before you go

Most Western travelers enter South Korea visa-free for 90 days, with the K-ETA travel authorization currently waived through December 2026 for many nationalities. Spring cherry blossoms and autumn foliage are the two best windows to visit.

South Korea has been gaining momentum alongside Japan as a 2026 travel favorite — efficient, easy to navigate, and increasingly on people's radar beyond just Seoul.

Best time to visit

Spring (March-April) brings cherry blossoms and mild weather; autumn (September-November) brings fall foliage and equally comfortable conditions. Both are the most popular windows and book up fast for accommodation. Summer (July-August) is hot, humid, and monsoon season; winter is cold but good for skiing near Pyeongchang.

Getting around

Seoul's subway is fast, cheap, and has English signage throughout — genuinely one of the easiest metro systems for first-time visitors. The KTX high-speed train connects Seoul to Busan and other major cities in a few hours, making a multi-city trip easy without renting a car.

Top things to do

Budget tips

Convenience store meals (편의점) are genuinely good and cut food costs significantly. Guesthouses and mid-range hotels near subway stations, rather than tourist-district hotels, stretch a budget noticeably further.

Where to stay

Myeongdong is convenient for shopping and central sights but busy and touristy; Hongdae suits a younger, nightlife-focused stay; Ikseondong offers a quieter, more local base close to the palaces.

Frequently asked questions

Do US and UK citizens need a visa for South Korea?

No for short stays. Visa-free entry covers 90 days for tourism, and the K-ETA travel authorization requirement is currently waived for US, UK, and many other nationalities through December 31, 2026 β€” confirm current status before flying since this is an extension, not a permanent exemption.

What is South Korea's e-Arrival Card?

A mandatory digital arrival form required from January 1, 2026 for all foreign visitors, replacing the old paper form previously filled out on the plane or at the airport.

What's the best time of year to visit South Korea?

Spring (March-April) for cherry blossoms and autumn (September-November) for fall foliage are the two most popular and scenic windows, both with mild, comfortable weather. Avoid July-August's monsoon humidity if possible.

Do I need an eSIM for South Korea?

It's worth having one. South Korea has excellent mobile coverage nationwide, and a travel eSIM keeps navigation and translation apps working immediately, which matters given how much signage relies on Korean.
