korea

South Korea is a compact country where in two weeks you can take in a megacity, beaches, mountain monasteries, and a volcanic island. The distances are short, the KTX crosses from one end to the other in 2.5 hours, and there's English on signs everywhere. This article lays out the practical boundaries for a first trip.

K-ETA: do you need it

K-ETA (Korea Electronic Travel Authorization) is an electronic entry permit for travelers from visa-exempt countries. US passport holders are on the visa-exempt list, so for short tourist stays you don't need a visa — but you do need to apply for K-ETA online before you fly. Apply at least a few days ahead; it's valid for multiple entries over an extended period, so one approval covers repeat trips.

One nuance worth knowing: if you're only transiting through Korea without leaving the airport, K-ETA isn't required. A transit with a city visit of up to 24 hours from Incheon into Seoul is handled by a separate "Korea Transit Tour" program, arranged at a desk in the airport.

Transport: KTX, buses, T-money

KTX (the high-speed train) is the spine of the country. Seoul → Busan in 2 hours 30 minutes, a ticket ₩53,000–60,000 one way. Book through Korail (the interface is in English and easy to follow). The Korea Rail Pass (KR Pass) for foreigners comes in 3-, 5-, or 7-day versions and pays off if you have 3+ long legs.

Buses — cheaper, and they go everywhere. Seoul → Busan express bus — ₩35,000, 4–4.5 hours. Useful for cities the KTX doesn't reach (Andong, for example).

T-money card — a card for everything in the city: subway, buses, taxis, even vending machines. You buy it at any konbini (CU, GS25, 7-Eleven) or subway station for ₩2,500–4,000 and top it up with cash or a card. It works in Seoul, Busan, Daegu, Daejeon, and on Jeju.

Budget

The baseline is ₩80,000–120,000 a day (roughly $60–90 USD at May 2026 rates; verify the current rate):

• Hostel / guesthouse — ₩25,000–40,000. A business hotel in Seoul — ₩70,000–110,000.
• Food — ₩20,000–40,000. Breakfast from a konbini — ₩4,000–6,000. Lunch at a kimbap bistro or cafeteria — ₩7,000–10,000. Dinner at a KBBQ or galbi spot — ₩15,000–25,000 per person.
• City transport — ₩5,000–8,000.
• Attraction tickets — ₩3,000–10,000 each.

A budget approach — around ₩60,000 a day. Comfort with dinners out and good hotels — ₩200,000+.

Route: Seoul + Busan + Jeju, 10–14 days

Seoul, 5–6 days. Palaces (Gyeongbokgung, Changdeokgung — definitely make use of the Joseon Royal Heritage Pass, ₩10,000 for all of them), Bukchon Hanok Village, Insadong, Hongdae for nightlife, Gangnam, and the DMZ as a day trip (through a tour — you can't do it on your own).

Busan, 3 days. KTX from Seoul. Gamcheon (the colorful village), Haeundae Beach, the Jagalchi fish market, Haedong Yonggungsa Temple on the cliffs. The atmosphere is far more relaxed than Seoul.

Jeju, 3–4 days. A flight from Busan or Seoul (60–80 min, ₩50,000–90,000). Hallasan Volcano (an 8–10 hour climb, with easier trails available), Cheonbang Falls, the Jusangjeolli cliffs. A car on the island is all but mandatory — public transport works, but slowly. A rental runs ₩50,000–80,000 a day if you have an International Driving Permit.

Festivals — when to plan a trip around an event

• Jinhae Cherry Blossom (Jinhae) — late March – early April. One of the best cherry blossom displays in Asia, without the Japanese crowds. Base yourself in Busan and go for the day.
• Boryeong Mud Festival — mid-July. Mud baths on Daecheon Beach, two weeks of chaos with heavy foreign participation. Budget — noticeably pricier during the festival week.
• Busan International Film Festival (BIFF) — early October, 10 days. Premieres of Asian cinema, more down-to-earth than Cannes or Venice. Book hotels three months ahead.
• Cheonan World Dance Festival — late September. If you're into folk dance from around the world, it's worth it. Otherwise, skip it.
• Andong Mask Dance Festival — late September – early October. Old Korea in its purest form; the small town of Andong comes alive for a week.

What I do when I'm not sure

Korea looks like a simple country on paper, but in practice questions come up: whether you can squeeze in Jeju on your schedule, whether the KR Pass pays off or individual tickets are cheaper, whether you fall within the cherry blossom window.
