South Korea is one of Asia’s most exciting travel destinations in 2026 – a country where ancient temples stand alongside glass skyscrapers, where street food vendors serve meals that rival Michelin-starred restaurants, and where the latest technology exists in harmony with centuries-old traditions. This South Korea travel guide for 2026 covers everything you need to know before your trip, from entry requirements and visa information to top attractions, best times to visit, and practical travel tips.
Entry Requirements for South Korea in 2026
Before planning your trip, confirm your entry requirements. Most major nationalities – including US, UK, EU, and Australian citizens – are currently exempt from the kETA (Korean Electronic Travel Authorization) through December 31, 2026. This means you can enter South Korea visa-free without any pre-travel authorization.
However, all travelers must complete the mandatory K-ETA e-Arrival Card before their flight arrives in Korea. This digital form is submitted at k-eta.go.kr and replaces the old paper arrival cards. It is free and takes about 10 minutes to complete. See our full Korea entry requirements 2026 guide for details.
If your nationality is not covered by the exemption or if you need kETA, the kETA application costs only KRW 10,000 (~$7.50 USD) and processes in minutes.
Best Time to Visit South Korea
South Korea has four distinct seasons, each offering a different experience:
- Spring (March – May): The most popular time to visit. Cherry blossoms transform parks and streets into pink landscapes. Temperatures are mild (10-20°C), making sightseeing comfortable. Book well in advance.
- Summer (June – August): Hot and humid, with temperatures reaching 30-35°C. The monsoon season (late June to mid-July) brings heavy rainfall. Summer is peak beach season on the coasts and Jeju Island.
- Autumn (September – November): Arguably the best time to visit. Crisp air, stunning foliage in reds and golds, and comfortable temperatures (10-20°C). Excellent for hiking and outdoor activities.
- Winter (December – February): Cold, with temperatures dropping below 0°C in Seoul. Snow is possible. Great for skiing in Gangwon-do and experiencing Korean winter festivals. Spring brings the lowest accommodation prices.
