Seoul to Busan by KTX in a Day

Yes, Busan works as a day trip from Seoul. The KTX from Seoul Station or Suseo reaches Busan Station in about 2 hours 20 minutes to 2 hours 50 minutes, and a standard adult seat costs ₩54,400 from Seoul Station (₩52,900 from Suseo), so a return is ₩108,800. The last daily train to Seoul Station leaves Busan at 10:10 p.m. Take a train around 7 a.m. and one back between about 7:30 and 8:30 p.m., and you get roughly 10 hours in Busan: enough for Gamcheon Culture Village, lunch at Jagalchi Market and an evening at Haeundae Beach.

Which Seoul station do KTX trains to Busan leave from?

Trains to Busan leave from Seoul Station and Suseo Station, not Yongsan: Korail’s timetable from November 1, 2026 has no Yongsan departures on the Busan line. Yongsan serves other lines, such as the KTX to Jeonju (Jeonju day trip).

Pick the station nearer where you are staying. Seoul Station is in the centre, and the AREX express from Incheon Airport runs straight to it (airport to Seoul guide). Suseo is in southeast Seoul, connected directly to subway Line 3 and the Suin-Bundang Line, which suits you if you are staying around Gangnam.

Suseo’s trains, once a separate service called SRT, have run as KTX since September 1, 2026, so both stations appear in one search.

How much is the KTX from Seoul to Busan?

A standard adult seat from Seoul Station to Busan costs ₩54,400 on most trains, per Korail’s fare table from September 1, 2026. Children aged 6 to 12 pay half, and from 13 you pay the adult fare, per the passenger options on Korail’s booking site.

The fare table also lists a premium (udeung) class at ₩65,300 from Seoul Station on the trains that have it. A same-day return in standard class from Seoul Station is ₩108,800.

The cheaper fares belong to slower trains. Trains that call at Miryang and Gupo take about 3 hours, for example the 9:28 a.m. from Seoul Station, which arrives at 12:35 p.m., and trains via Yeongdeungpo and Suwon take about 3 hours 20 minutes, for example the 8:12 a.m., arriving at 11:33 a.m. For a day trip, the half hour or more you save is worth more than ₩5,000, so we’d book a faster one.

How long is the KTX from Seoul to Busan?

Most trains take 2 hours 20 minutes to 2 hours 50 minutes. The fastest is the 9 a.m. from Suseo, arriving at 11:11 a.m. (2 hours 11 minutes); it runs only on Fridays, Saturdays, Sundays and Mondays, according to Korail’s November 1 timetable. From Seoul Station, the fastest morning train is the 8:58 a.m., which runs every day and arrives at 11:16 a.m.

What is the last KTX from Busan to Seoul?

The last daily train to Seoul Station leaves Busan at 10:10 p.m. and arrives at 12:42 a.m.; the last to Suseo leaves at 11 p.m. and arrives at 1:17 a.m. A selection of evening trains back that run every day in the November 1 timetable:

We’d book the 9 p.m. to Seoul Station or the 9:14 p.m. to Suseo at the latest, so you reach Seoul before midnight, and treat the 10 p.m. and 10:10 p.m. as fallbacks: arriving after midnight, plan on a taxi from the station (Kakao T guide).

How do foreign visitors book KTX tickets?

Foreign visitors book on Korail’s English website or in the KORAIL+ app. Seats go on sale at 7 a.m. two months before the travel date, payable by credit card. You don’t need a Korean phone number: Korail’s foreign-language booking asks only for passport details and an email address and accepts Visa and Mastercard cards issued abroad. You look up your ticket later with the email address and password you entered when buying, so note both down.

On board, your ticket is the mobile ticket in KORAIL+ or a home ticket printed from the website. Korail’s FAQ says screenshots and copies of a ticket are not valid.

KORAIL+ is the old Korail Talk app under a new name: Korail replaced Korail Talk with it on August 3, 2026, in seven languages, and it searches Seoul Station and Suseo trains together. Korail said the SRT app would keep taking non-member bookings for a while after September 1, but it is closing, and the SR booking site now points Suseo bookings to KORAIL+. Use KORAIL+ instead.

You can also buy at the station: from ticket machines until 10 minutes before departure, or at the ticket office until departure. Tickets are not sold at subway stations. Boarding without a ticket costs the fare plus a penalty of the same amount again, according to the FAQ.

Book the 7:38 p.m. back at the same time as your morning train: the return sets the length of your day. You can cancel online until departure. For Monday-to-Thursday trains, cancelling is free until 3 hours before departure and costs 5% after that. For Friday-to-Sunday and public-holiday trains it costs ₩400 until two days before, 5% the day before, 10% on the day until 3 hours before and 20% in the last 3 hours, per Korail’s refund table and its Korean-language version, which gives the ₩400 minimum.

Is the KORAIL PASS worth it for Busan?

Not for one day trip on its own. The KORAIL PASS is for foreign visitors only, and the cheapest version, the 2-day select pass, costs ₩131,000 for an adult (13 and over) and ₩66,000 for a child; you choose 2 travel days within 10 days. A standard return from Seoul Station to Busan is ₩108,800, so a single Busan day does not use it up.

It pays off when your second pass day is another long return. For example, Busan plus a return from Seoul Station to Gyeongju (₩44,500 each way) would cost ₩197,800 at full fare, against ₩131,000 for the pass.

How it works on a Busan day: you reserve seats from two months before, and the pass allows up to two seat reservations per person per day, which covers one outbound and one return. If seats are sold out, you can board a standing place with the pass and your passport. Pass holders can upgrade to first class for 50% of the route’s first-class fare, per the KORAIL PASS page. Carry your passport on board; a screenshot of a ticket is not valid.

Plan pass journeys from Seoul Station. Korail’s pass notice says the pass is not valid on SRT trains, and as of November 2, 2026, Korail’s English pages had not said whether that changed when Suseo’s trains became KTX on September 1, 2026.

How do you get around Busan in a day?

Use the metro, and pay with the same T-money card you use in Seoul. T-money gets Busan’s transfer discounts, and the metro runs from 5 a.m. to 11:59 p.m. Busan Station is on Line 1, and Seomyeon is where Line 1 meets Line 2.

A ride costs ₩1,600 by transport card up to 10 km from the station where you board (section 1) and ₩1,800 beyond that (section 2); single-use QR tickets from station machines cost ₩1,700 and ₩1,900. A 1-day pass is ₩6,000, bought in the Busan Subway app rather than loaded on your card. It is not valid on the Donghae Line or the airport light rail.

The plan below uses four metro rides: Busan Station to Toseong and Toseong to Jagalchi (section 1), then Jagalchi to Haeundae and Haeundae back to Busan Station (section 2); changing lines at Seomyeon is part of the same ride. That comes to ₩6,800 by T-money before any bus-to-metro transfer discount, so the ₩6,000 day pass is slightly cheaper if you set up the app.

Gamcheon Culture Village is a hillside neighbourhood of pastel houses, settled by refugees during the Korean War and decorated by students, artists and residents from 2009. People live there, so Visit Busan asks visitors to keep quiet and not fly drones. Jagalchi Market is one of Korea’s largest fish markets, where you can eat fresh sliced raw fish, grilled fish or spicy fish stew looking out over the sea. Haeundae is the city’s best-known beach, 1.5 km of white sand that draws visitors all year, not only in summer.

How do you plan a Busan day trip from Seoul?

Our suggested plan uses daily trains and starts in the west of the city, where Gamcheon and Jagalchi sit close together on Line 1, then crosses to Haeundae for the evening. If your date falls on the first, third or fifth Tuesday, Jagalchi is closed; have lunch around Nampo instead.
