First Trip to South Korea: A 2026 Planning Guide

2026-06 8 min read EN

At a glance — Travelers from the US, UK, Canada, Australia, NZ, and Ireland can enter South Korea visa-free and without K-ETA through December 31, 2026, but must file the online e-Arrival Card before flying. Plan a week for Seoul, add Busan, Gyeongju, or Jeju as time allows, and install Naver Map, KakaoMap, and Papago before you leave — Google Maps is heavily restricted in Korea.

When to go and how long to stay

Spring (April–May) and fall (October to mid-November) are widely considered the best windows: mild temperatures, low humidity, and frequently clear skies. They are also peak tourist seasons, so book ahead in Seoul, Gyeongju, and Busan.

Summer (late June to late August) is hot and very humid, with the monsoon arriving in July; August can feel above 95°F (35°C). Winter is dry but cold, with possible snow and sub-freezing temperatures in Seoul.

On duration: a first trip rarely fits in fewer than 7 nights on the ground, given jet lag and long-haul flight times (roughly 14 hours from the US West Coast, 11 hours from London, 10 hours from Sydney). A rough framework:

  • 4 to 5 days: Seoul only, optionally a day trip to Suwon or the DMZ.
  • 8 to 10 days: Seoul + Busan, or Seoul + Gyeongju + Busan via KTX.
  • 15 days and up: add Jeju, the Seoraksan or Jirisan national parks, or traditional villages (Andong-Hahoe, Jeonju).

Entry formalities in 2026

Three documents to keep straight:

  • Passport in good condition. Korea does not formally require six months of validity beyond your exit date, but a damaged passport may cause problems.
  • Visa: not required for tourist stays under 90 days for US, UK, Canadian, Australian, NZ, and Irish citizens (and most Western European nationalities). Confirm your specific nationality on hikorea.go.kr.
  • K-ETA (Korea Electronic Travel Authorization): Korea has extended the exemption for 67 countries — including all the above — through December 31, 2026. No K-ETA needed for tourist travel in 2026.
  • e-Arrival Card: in principle, any traveler without a valid K-ETA must submit an arrival declaration. File it for free online at e-arrivalcard.go.kr within 72 hours of arrival. The paper card handed out on board is generally still accepted as a fallback, and no official end date for the paper version has been announced.

On the customs front, some over-the-counter medications common in Western countries are restricted in Korea. Check the Korea Customs Service list if you travel with prescriptions or controlled substances (codeine, certain ADHD medications, some sleep aids).

Book ahead or wing it

A classic question for a longer trip: lock everything in, or leave room to improvise?

The practical rule used by repeat visitors:

  • Firmly book the first nights and the last night in Seoul, ideally near Seoul Station (KTX) or on the AREX line to Incheon Airport. This cushions jet lag on arrival and secures your departure.
  • Book ahead in destinations with limited inventory: national parks (Seoraksan, Jirisan, Hallasan), islands, traditional villages like Andong-Hahoe, or Gyeongju in high season.
  • Favor flexible cancellation rates: handy when your itinerary shifts on the ground, which happens often on a first trip.
  • For Jeju, domestic flights from Seoul-Gimpo run constantly (dozens of daily departures to Jeju International), but they are often non-refundable.
  • KTX trains, express buses, museum and palace tickets: bookable at the counter or online a few days ahead, often even same-day outside weekends and Korean public holidays. KORAIL opens reservations up to one month before departure.

In peak season (cherry blossoms in April, fall foliage in October–November, long Korean weekends), booking one to two weeks ahead remains sensible even for secondary cities.

A first-trip itinerary

Seoul (4 to 7 nights)

A week lets you string together palaces (Gyeongbokgung, Changdeokgung), hanok villages (Bukchon, Ikseondong), distinct neighborhoods (Insadong, Myeongdong, Hongdae, Gangnam), markets (Gwangjang, Namdaemun), and walks along the Han River. Insadong is often recommended as a base for a first visit: central, well served by subway, and close to the major palaces. Hongdae or Myeongdong suit younger travelers or those who want late-night energy.

Day trips worth considering from Seoul:

  • Suwon (Hwaseong Fortress, UNESCO-listed), about an hour by subway or KTX.
  • DMZ (demilitarized zone). Visits require an organized tour. The JSA (Panmunjeom, the blue buildings) partially reopened in summer 2025 but remains restricted-access and runs on limited dates. Standard tours include the Dora Observatory, an infiltration tunnel, and Dorasan Station.
  • Nami Island, Pocheon Art Valley, or hiking near Bukhansan National Park.

Busan (2 to 3 nights)

Korea's second city, about 2h15 from Seoul by KTX. Highlights include the colorful Gamcheon Culture Village, Jagalchi Market, Haeundae and Gwangalli beaches, and Haedong Yonggungsa temple on the coast. The city sprawls, so factor in subway and bus time between sights.

Gyeongju (2 to 3 nights)

The ancient capital of the Silla kingdom, a major site for heritage travel: royal tumuli, the Anapji-Donggung pond lit at night, Bulguksa temple, and the Seokguram grotto (about 20 minutes by car, 45 minutes by bus). Bike rentals are easy and make sightseeing efficient. A good compromise for adding a traditional dimension to a Seoul-centric trip.

Jeju (3 to 5 nights)

Volcanic island off the south coast, reached by domestic flight from Seoul-Gimpo (about 45 minutes, with departures every 5 to 10 minutes during the day). Draws include Hallasan National Park, the east and south coasts, and tiny Udo Island. Jeju measures about 45 miles (73 km) east to west, so renting a car (international driving permit required) is by far the simplest option. Buses cover the main sights but eat into your time.

Transport: T-money, KTX, subway

The T-money card

This is the universal prepaid card: subway, bus, taxi, and purchases at most 24-hour convenience stores (CU, GS25, 7-Eleven, Ministop, E-Mart 24).

  • Where to buy: vending machines and convenience stores at Incheon Airport, subway stations, and corner shops citywide. Expect ₩2,500 to ₩6,000 for the card itself depending on the design (roughly $2 to $5).
  • Top-ups: cash at subway-station machines, or card at some convenience stores.
  • Transit fares: a base subway ride in Seoul starts around ₩1,400 (about $1); buses run ₩1,200 to ₩3,000 depending on the route color.

A useful alternative is WOWPASS, a prepaid card aimed at foreign visitors that combines T-money transit functionality with retail payment, rechargeable in foreign currency (USD, EUR, etc.) via kiosks or the app. It can simplify currency exchange on arrival.

Airport transfer

Three options from Incheon to Seoul:

  • AREX Express: direct train to Seoul Station in about 43 minutes, around ₩13,000 at the gate (often cheaper if pre-booked online).
  • AREX All Stop: local train, cheaper, pay with T-money like the subway.
  • Airport limousine buses: convenient if your hotel sits on a direct route.

KTX and long-distance buses

The KTX is Korea's high-speed rail. Book online at the Korail site (letskorail.com, English interface) or via the KorailTalk app. Plan on about 2h15 for Seoul–Busan and roughly 2 hours for Seoul–Gyeongju (Singyeongju station). For shorter distances or areas the rail network doesn't reach well, express buses are comfortable and inexpensive.

Worth noting: in February 2026, KORAIL and SRT launched a pilot cross-operation (one round trip per day, with broader integration planned by late 2026). No real impact on a first trip.

Internet, payments, language: the digital toolkit

Connectivity

You will need internet constantly: navigation, translation, payments, taxis. Three options:

  • eSIM activated before departure — the simplest option for most recent smartphones.
  • Physical prepaid SIM sold at Incheon Airport or in town.
  • Pocket Wi-Fi rented at the airport, useful for couples or families.

Apps to install before you leave

  • Naver Map or KakaoMap: Google Maps remains restricted in Korea for regulatory reasons (no detailed walking or driving directions). Naver Map offers multilingual support (English, Japanese, Chinese) that many foreigners find easier to navigate. KakaoMap includes an AR walking mode.
  • Papago: Naver's translator, better at Korean than Google Translate. Handles menu and sign photos plus voice conversations.
  • KakaoTalk: the messaging app everyone in Korea uses, useful for contacting hotels, guides, or rental agencies.
  • Kakao T: the local Uber-equivalent for hailing taxis.
  • KorailTalk: KTX bookings.
  • Subway Korea or equivalents: offline subway maps.

Payments

Korea is overwhelmingly cashless: credit cards work almost everywhere, including small convenience stores and taxis. Still, carry some won (cash) for markets, small eateries, temples, or in case of a network outage. Global ATMs (Woori Bank, KB, Citibank, some GS25 stores) accept foreign cards. A no-foreign-fee debit card (Wise, Revolut, Charles Schwab, etc.) helps avoid surcharges.

Language

Korean is essential outside tourist zones. In Seoul, at major stations, and in well-known hotels and restaurants, you'll find functional English, especially among younger staff. In the provinces and smaller shops it's more hit-or-miss — Papago closes the gap. Hangeul (the Korean alphabet) takes only a few hours to learn: being able to read station names and storefronts changes how you move through the country.

Smart habits before you leave

  • Check the season's weather and pack accordingly (humid summer, cold winter, pleasant shoulder seasons).
  • Buy travel insurance that covers medical care and repatriation: Korean healthcare is excellent but billed at full cost to foreigners.
  • Photocopy or scan passport, tickets, and reservations.
  • Activate cellular data or eSIM before leaving the airport for navigation and Papago.
  • Keep some won in cash for your first rides while you wait on a T-money or WOWPASS card.
  • Register with your country's traveler program for longer trips: STEP (US), LOTUS (UK FCDO updates), Smartraveller (Australia), Registration of Canadians Abroad (Canada).
