1 Week in South Korea: Seoul, Busan, and Jeju

This 1 week South Korea itinerary gives you three full days in Seoul, two in Busan, and two in Jeju, linked by KTX and short flights for a fast-paced but doable Korea travel plan. Daily costs range from roughly $70–90 for backpackers to $220–300+ for luxury in 2026.

If you want a Seoul–Busan–Jeju 7‑day route that balances culture, food, beaches, and nature, this plan is a reliable template you can copy and tweak. You’ll use the KTX bullet train between Seoul and Busan, then short hops to Jeju, all while staying connected with a Hello eSIM and tracking expenses in the Hello app.

In 2023, South Korea welcomed over 11 million visitors according to the Korea Tourism Organization, and popular routes like this are busy year‑round—booking KTX tickets, domestic flights, and hotels 2–4 weeks ahead is strongly recommended, especially in cherry blossom season (late March–early April) and autumn foliage (late October–early November).

Use this guide as your Korea trip planner: every day is broken down into morning, afternoon, and evening with transport notes, food ideas, and a quick budget overview for budget, mid‑range, and luxury travellers.

Day 1 of this 1 week South Korea itinerary focuses on getting from Incheon to central Seoul, seeing your first royal palace, and diving straight into Myeongdong’s food streets without overloading a jet‑lagged day.

Morning (Arrival & transfer)
Most international flights land at Incheon (ICN). Take the AREX Express to Seoul Station (43–50 minutes, about $9–10 in 2026) or the all‑stop train (around $4–5, 60 minutes). According to Korea Tourism Organization guidance, both run frequently from early morning to around 11:30 pm. Check into your hotel in Myeongdong or Jongno, ideal bases for first‑timers.

Afternoon (Gyeongbokgung & Bukchon)
Head to Gyeongbokgung Palace, the grandest of Seoul’s five palaces. Entry is roughly 3,000 KRW (about $2.50) and free if you’re wearing hanbok. Hanbok rental near the palace starts around $10–15 for 2 hours in 2026. Time your visit for the 10:00 or 14:00 changing‑of‑the‑guard ceremony. Afterwards, stroll through Bukchon Hanok Village for traditional houses and photo spots—remember it’s a residential area, so speak quietly.

Evening (Myeongdong food trail)
Back in Myeongdong, follow the neon streets for snacks: tteokbokki ($4–5), hotteok ($2–3), and cheese‑filled Korean corn dogs (~$3–4). A basic sit‑down dinner like kimchi jjigae or bibimbap will run $8–12. Use the Hello app to snap your first food receipts with AI scanning and start tracking your trip budget from day one.

Estimated day‑one budget (USD, 2026)

• Budget: $70–90 (AREX all‑stop, guesthouse, street food)
• Mid‑range: $120–160 (AREX Express, 3‑star hotel, palace + hanbok)
• Luxury: $220–300+ (private airport transfer $70–90, upscale hotel, guided palace tour)

Day 2 in Seoul is for ticking off the classic sights—palaces and hanok lanes by day, then either Hongdae nightlife or N Seoul Tower views after dark, depending on your style.

Morning (Palace combo & museums)
If you bought the integrated palace ticket (covers multiple palaces for about 10,000 KRW, roughly $8), use it to visit Changdeokgung and the Secret Garden. Guided garden tours cost a few extra dollars and must be timed; many travellers find this the most atmospheric palace. Alternatively, dive deeper into history at the National Palace Museum or National Folk Museum, both near Gyeongbokgung and free or low‑cost.

Afternoon (Insadong & Jongno eats)
Walk to Insadong, known for calligraphy shops, galleries, and tea houses. Try a traditional tea set for around $6–10. Lunch on kalguksu (knife‑cut noodles) or dumplings for $8–12. Wander the side streets of Ikseon‑dong, a revived hanok area packed with small cafés and cocktail bars—great for photos.

Evening options (pick one)

• Hongdae: University‑area with buskers, indie shops, and casual bars. Dinner (K‑BBQ, $15–25 per person without drinks) plus a bar stop ($6–9 per drink).
• N Seoul Tower (Namsan): Cable car return tickets are around $12–15; observatory tickets about $10–12. Come for sunset and night views over the city.

To keep your Korea travel plan on budget, log subway fares (~$1.20–1.50 per ride with a T‑money card) and dining costs in the Hello app. Multi‑currency tracking and automatic exchange rates help if you’re splitting bills with friends from different countries.

Estimated daily budget (USD, 2026)

• Budget: $60–80
• Mid‑range: $110–150
• Luxury: $220–280 (private guides, fine‑dining dinner, taxis instead of subway)

Day 3 is ideal for exploring Seoul’s modern side—Gangnam, COEX, or the Han River—or adding a DMZ tour, while also locking in KTX tickets for Busan for the next morning.

Morning (Choose: DMZ tour or Gangnam/COEX)

• DMZ tour: Many operators run half‑day tours from Seoul, typically 7:30 am–2:30 pm, costing around $60–90 in 2026. You’ll visit Imjingak, Dora Observatory, and the Third Tunnel, with hotel pickup in central areas. Book at least a week ahead, especially in peak season.
• Gangnam & COEX: Visit the Starfield Library inside COEX Mall, then Bongeunsa Temple across the street—free, peaceful, and photogenic.

Afternoon (Han River or shopping)
Head to Yeouido Hangang Park or Banpo Hangang Park to see locals picnic and cycle along the Han. Rental bikes cost around $3–5 per hour via local apps or kiosks. Alternatively, shop for beauty products in Myeongdong or Lotte Department Store.

Evening (Last Seoul dinner & KTX planning)
Enjoy a final Seoul dinner—maybe another round of K‑BBQ or fried chicken and beer (chimaek) for $15–25 per person. Then reserve your KTX tickets from Seoul Station to Busan for tomorrow morning. As of 2026, a one‑way KTX ticket in standard class is around 60,000–65,000 KRW (about $45–50) and takes roughly 2.5–2.8 hours, according to Korail timetables.

Use the Hello app as your Korea trip planner to note your KTX departure time, seat number, and expected spend in Busan. The app’s expense splitting makes it easy to divide DMZ tour fees, K‑BBQ, and taxis among friends.

Estimated daily budget (USD, 2026)

• Budget: $70–90 (local food, subway, no DMZ)
• Mid‑range: $130–170 (DMZ tour or shopping, some taxis)
• Luxury: $230–320 (private DMZ, upscale dining, spa visit)

Day 4 of this Seoul–Busan–Jeju itinerary takes you south on the KTX bullet train, dropping you in Busan by late morning to enjoy beaches, seafood, and a relaxed coastal vibe.

Morning (KTX to Busan & check‑in)
Catch a morning KTX from Seoul Station to Busan: around 2 hours 40 minutes, with standard tickets roughly $45–50 one‑way in 2026. It’s best to leave between 8:00–10:00 am so you can check into your hotel by lunchtime. Base yourself near Haeundae (beachy and modern) or Seomyeon (central and lively).

Afternoon (Haeundae Beach & Blueline Park)
Walk along Haeundae Beach, one of Korea’s most famous stretches of sand. In summer, rent parasols and chairs (~$10–15). Consider riding the Haeundae Blueline Park Sky Capsule or Beach Train, a colourful coastal train with sea views; tickets are in the $10–14 range depending on route and time.

Lunch on seafood or spicy jjampong at a local restaurant for about $10–15. Busan’s casual eateries often serve generous portions, great for sharing.

Evening (Gwangalli or Haeundae night)
Head to Gwangalli Beach for illuminated views of Gwangan Bridge, plus cafés and bars. On Saturdays, there is a popular drone show above the bay (free to watch), which has become one of Busan’s signature night experiences, according to Busan Tourism Organization updates. A seafood dinner with grilled clams or sashimi runs $18–30 per person.

Keep your costs in check by logging KTX, Blueline tickets, and shared seafood platters in the Hello app, which can automatically split everything between travellers.

Estimated daily budget (USD, 2026)

• Budget: $90–110 (standard KTX, guesthouse, simple meals)
• Mid‑range: $150–190 (3‑star near Haeundae, Blueline, seafood dinner)
• Luxury: $260–350+ (5‑star beach hotel, private transfers, upscale seafood)

Day 5 in Busan is all about the colourful hills of Gamcheon Culture Village, the chaos of Jagalchi Fish Market, and a relaxing jjimjilbang spa session to recharge mid‑itinerary.

Morning (Gamcheon Culture Village)
Start early at Gamcheon Culture Village, often called Korea’s Santorini thanks to its stacked pastel houses and ocean views. From Toseong Station, take a short bus or taxi up the hill (a few dollars). Most cafés open around 10:00 am. Budget $5–10 for coffee and a snack.

Afternoon (Jagalchi Market & Nampo)
Head down to Jagalchi Fish Market, Korea’s largest seafood market. According to Busan city guides, it remains one of the country’s best places to try ultra‑fresh raw fish. Pick your seafood on the ground floor and have it prepared upstairs; expect $20–30 per person for a generous meal. Afterwards, wander through Gukje Market and Nampo‑dong for street snacks and shopping.

Evening (Spa Land or more beach time)
If you like spas, go to Spa Land Centum City, one of Korea’s most famous jjimjilbangs. Entry is about $20 for up to 4–6 hours, with multiple themed saunas and baths. Otherwise, return to Haeundae or Gwangalli Beach for sunset, bingsu (shaved ice dessert, $7–10), and craft beer.

Local metro rides are around $1.20–1.50, and taxis within central Busan usually run $6–12 depending on distance and traffic. Track these small but frequent costs in the Hello app so your 1 week South Korea itinerary stays on‑target financially.

Estimated daily budget (USD, 2026)

• Budget: $65–85
• Mid‑range: $120–160 (seafood lunch, spa entry, some taxis)
• Luxury: $230–280 (private tour, premium seafood, spa add‑ons and massages)

Day 6 of your Korea travel plan moves you from cityscapes to volcanic landscapes as you fly from Busan to Jeju, then explore the island’s west coast beaches and cafés.

Morning (Busan to Jeju flight)
Take a morning flight from Busan’s Gimhae Airport (PUS) to Jeju (CJU). Low‑cost carriers operate frequently; typical fares in 2026 are $40–80 one‑way if booked a few weeks ahead. Flight time is about 1 hour. On arrival, either rent a car (~$45–65 per day before fuel and insurance) or use airport buses and taxis. Many visitors choose Seogwipo (south) or Aewol/west coast as their base.

Afternoon (West Jeju coastal drive)
Explore Aewol and the west coast: scenic cafés, rocky shores, and, in summer, swimmable beaches. Spots like Woljeongri Beach are famous for turquoise water and trendy cafés. A café drink is usually $5–8, while a simple lunch like abalone porridge or black pork bowl costs around $10–15.

Evening (Seafood dinner & sunset)
Drive or bus to a sunset viewpoint such as Suwolbong Peak on the west or a coastal café with terrace seating. Jeju is known for jeonbokjuk (abalone porridge) and black pork BBQ; expect $18–30 per person for dinner at a mid‑range place.

Because Jeju is spread out and public transport is less dense than Seoul or Busan, having reliable data is key for navigation. Using Hello eSIM for South Korea from your arrival means you can run maps, translation, and weather apps without hunting for SIM counters.

Estimated daily budget (USD, 2026)

• Budget: $110–140 (cheaper flight, buses, guesthouse)
• Mid‑range: $170–220 (car rental split between 2–3 people, mid‑range hotel)
• Luxury: $320–420+ (ocean‑view resort, business‑class fares, private driver)

Your final day combines a sunrise at Seongsan Ilchulbong with a few last Jeju sights before flying back to Seoul or directly home, wrapping up a full Seoul–Busan–Jeju week.

Early Morning (Seongsan Ilchulbong)
Aim for Seongsan Ilchulbong (Sunrise Peak), a UNESCO‑listed tuff cone on Jeju’s east coast. The climb takes about 20–30 minutes each way on stairs. Entry fees are around $4–5 for adults as of 2026. For sunrise, arrive at least 30–40 minutes before posted sunrise time.

Late morning (Optional: Udo Island or Manjanggul)
If time allows, ferry to Udo Island from Seongsan Port (around 15 minutes; return tickets roughly $8–10). Rent an electric bike or scooter (~$15–20) to circle the island’s beaches. Alternatively, visit Manjanggul Lava Tube, one of the world’s longest lava tunnels open to tourists, with entry about $3–4.

Afternoon (Return & fly out)
Drive or bus back toward Jeju Airport. Domestic flights from Jeju to Seoul’s Gimpo (GMP) run frequently, taking about 1 hour and often costing $40–90 depending on season and booking window. Allow at least 2 hours at the airport for check‑in and security. If connecting internationally at Incheon, planners like the Korea Tourism Organization recommend at least a 2.5–3 hour connection.

Use the Hello app to export your trip’s expense summary—handy if you’ve been splitting bills in multiple currencies and want a clean final breakdown.

Estimated daily budget (USD, 2026)

• Budget: $120–150 (public transport, simple meals, domestic flight)
• Mid‑range: $170–230 (car rental, activities, nicer lunch)
• Luxury: $320–450+ (business‑class flights, driver, fine‑dining lunch with wine)

This Q&A covers the most common questions travellers ask when planning a 1 week South Korea itinerary that includes Seoul, Busan, and Jeju, from budgets and best seasons to transport and connectivity.

Q1: Is 1 week enough for Seoul, Busan, and Jeju?
Yes, if you move efficiently. You’ll get about 3 days in Seoul, 2 in Busan, and 2 in Jeju. It’s a highlight reel, not a deep dive, but it works well for first‑timers.

Q2: How much money do I need for 7 days in Korea?
In 2026, many travellers manage on $700–900 total for budget trips (including transport and simple stays), $1,200–1,800 for mid‑range, and $2,300+ for luxury. Use the Hello app to track in KRW while seeing totals in your home currency.

Q3: What’s the best season for this route?
Spring (late March–May) and autumn (late September–early November) offer mild weather and, according to Korea’s weather agency statistics, some of the year’s clearest days. Summer is humid and hot, while winter is cold but less crowded.

Q4: Do I need to pre‑book KTX trains?
For weekends, holidays, and cherry blossom season, absolutely—Korail data shows high occupancy on Seoul–Busan runs at those times. On regular weekdays, you can sometimes book same‑day but advance booking is still safer.

Q5: Is an eSIM useful in South Korea?
Yes. Having mobile data for maps, Kakao Taxi, translation, and restaurant searches makes this Seoul–Busan–Jeju route much easier. An eSIM from Hello lets you arrive connected and avoid hunting for SIM kiosks.

Q6: Can I do this trip with friends and split costs easily?
Yes—hostels and shared Airbnbs are common, and the Hello app makes expense splitting simple across multiple currencies, with AI receipt scanning and automatic exchange rates so no one has to be the spreadsheet person on the trip.
