South Korea Travel Guide: Seoul, Busan, Jeju & Where to Go in 2026

Most Western travelers don't need a visa for short stays — and through December 31, 2026, citizens of 67 visa-exempt countries (including the US, UK, Canada, Australia, Japan, Singapore, and most of the EU) are also exempt from K-ETA, the electronic travel authorization. You just need a valid passport, a return ticket, and the new mandatory e-Arrival Card (free, online, completed before arrival as of 1 January 2026). Most visa-exempt nationals get up to 90 days per entry; Canadians get up to 180. Nationals from non-exempt countries — including Russia, China, and India — still need a visa applied for at a Korean consulate. Always check the K-ETA waiver status closer to travel — it has changed yearly. Passport must be valid for at least 6 months.

Seven days is the minimum for a meaningful trip — four in Seoul, three in Busan, connected by the 2.5-hour KTX high-speed train. Ten days adds Jeju Island, Korea's volcanic resort island that feels like a different country (1-hour flight from Seoul or Busan). Fourteen days lets you add Gyeongju (the old Silla dynasty capital, the country's most concentrated historic site), Andong (hanok villages, traditional masks, Confucian heritage), or skiing in Pyeongchang in winter. Seoul alone deserves four days minimum — Gyeongbokgung at opening, an evening in Hongdae, lunch at Gwangjang Market, a half-day in Bukchon and Ikseon-dong, and Itaewon or Seongsu-dong for the modern side. T-Money card on day one — it works on every metro, bus, and most taxis.

Two short, perfect windows. Spring (late March to mid-May) for cherry blossoms — peak bloom is usually the first week of April in Seoul, slightly earlier in Busan and Jeju. Autumn (mid-October to mid-November) for the country's other star season — the fall foliage in Naejangsan and Seoraksan National Parks is genuinely spectacular, often more dramatic than spring. Summer (late June to mid-August) is hot, very humid, and includes a serious rainy season (jangma) in late June through mid-July — Busan's beaches are at their best but the rest of the country sweats. Winter is bitterly cold in Seoul (regularly below -10°C), but it's also when ski resorts open and Seoul's empty palaces dusted with snow are the most beautiful sight in Korea.

Start with the markets. Gwangjang Market for the iconic street-food trifecta — bindaetteok (mung bean pancake), mayak gimbap (mini rice rolls), and live octopus if you're brave. Tongin Market for the dosirak café (use brass tokens to assemble your own tray of banchan). For Korean BBQ done seriously, Yeontabal in Mapo for galbi or Saebyeokjip for hangover-soup-and-pork. For modern Korean fine dining, Mingles (Michelin three-star) is the answer — book months ahead. Gangnam is where the trendy expensive spots cluster; Hongdae and Itaewon for late-night drinking food; Seongsu-dong for the new specialty coffee and pastry scene. Always look for the long line of office workers at lunch — it's the most reliable signal in the city.

If you have 10+ days in Korea, yes. Jeju is volcanic, semitropical, and culturally distinct — Koreans treat it as their honeymoon and weekend escape destination. The main draws: Hallasan, South Korea's tallest mountain (a moderate but long full-day hike to the crater), the dramatic Seongsan Ilchulbong sunrise peak (UNESCO-listed), the lava-tube cave system in the northeast, and quiet beaches like Hyeopjae and Hamdeok. Flights from Seoul Gimpo to Jeju run nearly every 15 minutes for $40–80 one-way. Rent a car on arrival — the island is built for driving, and bus connections between sights are slow. Three or four days covers the highlights. Skip Jeju in summer if you can — it's the busiest domestic destination in Korea and beaches get packed.
