How to Plan a Trip to South Korea

Plan a South Korea trip by deciding between Seoul-focused (3-5 days), Seoul + one region (7-10 days), or multi-region (14+ days). Book flights 2-3 months ahead, arrange a K-ETA visa waiver online ($10, takes 24 hours), and budget $60-100 per day depending on accommodation style. Spring (April-May) and fall (September-November) offer the best weather.

  1. Decide your trip length and structure. 3-5 days: Stay in Seoul. Cover palaces, markets, neighborhoods, and day trips to DMZ or Suwon. 7-10 days: Seoul plus one region—Busan for beaches and seafood, Jeju Island for nature, or Gyeongju for temples and history. 14+ days: Multi-region circuit hitting Seoul, Busan, Gyeongju, and Jeju, or add rural areas like Jeonju or the east coast.
  2. Pick your season. Best: April-May (cherry blossoms, mild weather) or September-November (fall colors, comfortable temperatures). Summer (June-August) is hot, humid, and rainy but great for beach destinations. Winter (December-February) is cold but good for skiing and fewer tourists. Avoid Chuseok (Korean Thanksgiving, usually late September) and Lunar New Year (late January-February) when transport is packed and many businesses close.
  3. Book flights early. International flights to Seoul (ICN) from major US cities run $600-1200 round trip. Book 2-3 months ahead for better prices. Direct flights exist from LAX, SFO, JFK, and others. Budget carriers like T'way and Jeju Air offer cheap domestic flights within Korea (Seoul to Busan $30-60). KTX high-speed trains are a comfortable alternative and get you Seoul to Busan in 2.5 hours for $50.
  4. Sort your visa situation. US, Canadian, UK, EU, and Australian passport holders don't need a visa for stays under 90 days but DO need a K-ETA (Korea Electronic Travel Authorization). Apply online at k-eta.go.kr at least 24 hours before departure. Costs $10, valid for 2 years. Takes 5 minutes to apply, approval usually within 24 hours. Other nationalities check visa requirements at your nearest Korean embassy.
  5. Book accommodation strategically. Seoul: Stay in Myeongdong (central, tourist-friendly), Hongdae (nightlife, youth culture), or Gangnam (modern, upscale). Hostels $20-30, guesthouses $40-60, hotels $80-150. Busan: Haeundae Beach area or Seomyeon district. Jeju: Jeju City or Seogwipo depending on itinerary. Book hotels on Agoda or Booking.com. Hanok stays (traditional guesthouses) available in Seoul's Bukchon area and Jeonju for $60-100.
  6. Plan your internal transport. Seoul: T-money card ($3) works on subway, buses, and convenience store purchases. Subway is the easiest way to get anywhere. Between cities: KTX trains are fast and punctual—book at letskorail.com. Buses are cheaper but slower. Jeju Island requires a rental car or tour buses as public transport is limited. International Driver's Permit needed to rent a car.
  7. Build your itinerary around key experiences. Seoul: Gyeongbokgung Palace, Bukchon Hanok Village, Insadong, Myeongdong shopping, Dongdaemun night market, N Seoul Tower, Gangnam district. Add DMZ tour (full day). Busan: Haeundae Beach, Gamcheon Culture Village, Jagalchi Fish Market, Haedong Yonggungsa Temple. Jeju: Seongsan Ilchulbong crater, Manjanggul lava tube, Hallasan National Park, beach coastline. Gyeongju: Bulguksa Temple, Seokguram Grotto, Daereungwon tomb complex. Don't overschedule—leave time for cafes, random exploring, and Korean BBQ sessions.
  8. Learn basic Korean etiquette. Bow slightly when greeting. Remove shoes when entering homes and some traditional restaurants. Use two hands when giving or receiving something from elders. Don't tip—it's not customary and can be awkward. Learn basic phrases: annyeonghaseyo (hello), gamsahamnida (thank you), juseyo (please/give me). English signage is common in Seoul, less so elsewhere.
