Seoul to Daejeon by KTX: Sungsimdang, Expo Park and Hot Springs

Yes, Daejeon is an easy day trip from Seoul. The KTX from Seoul Station takes roughly an hour, and Daejeon's three big draws are all a short subway or taxi ride from the station. You can buy bread at the famous Sungsimdang bakery near the station, walk around Expo Science Park and Hanbit Tower in the afternoon, and finish with a free hot-spring foot bath in Yuseong before the train back. This guide shows how to put that day together, and what to check before you go.

Getting from Seoul to Daejeon

KTX from Seoul Station or Yongsan

Most KTX trains on the Gyeongbu Line (the line to Busan) stop at Daejeon Station, so you have many departures to choose from all day. The ride is about an hour, which makes Daejeon one of the quickest KTX day trips from Seoul. Book on the official Korail website or the Korail Talk app. Both have English, and you can pay with an overseas card. Weekend mornings and Friday evenings fill up, so buy your outbound and return tickets a few days ahead if you can. If you have never booked a Korean train, our KTX booking guide for tourists walks through the same steps.

SRT from Suseo (south Seoul)

If you are staying in Gangnam or the south-east of the city, the SRT from Suseo Station also runs to Daejeon. It is a separate company with its own website and app, and the Korea Rail Pass does not normally cover it, so check before you buy.

Daejeon Station vs Seodaejeon Station

Watch the station name. Trains on the Gyeongbu Line stop at Daejeon Station, which is the one you want for this route. Some trains heading south-west toward Gwangju and Mokpo stop at Seodaejeon instead, which is farther from the old downtown. If you end up there, a taxi or the subway (from the nearby Seodaejeon Negeori stop) gets you back on track.

Express bus as a cheaper backup

Express buses run from Seoul Express Bus Terminal and Dong Seoul to Daejeon. They are cheaper than the KTX but slower, and traffic can add time on weekends. For a one-day trip, the train is usually worth it.

Morning: Sungsimdang bakery

Sungsimdang is the reason many Koreans visit Daejeon at all. The bakery opened in 1956 in front of Daejeon Station, it has stayed a Daejeon-only brand, and people come from all over the country for its bread. It now runs several shops in the city.

Which branch to visit

Main store (Eunhaeng-dong): The original flagship in the old downtown, about one subway stop from Daejeon Station. Jung-ang-ro Station on Daejeon Metro Line 1 is the closest. The area around it, with older streets, cafés and the Eunhaeng-dong shopping street, is pleasant to walk. Lines here can be long, especially on weekends, and queues sometimes start before opening.
Daejeon Station branch: Inside the station building, so it is the easiest choice if you are short on time or want to buy bread on your way home. Lines are usually shorter than at the main store, but it still gets busy at peak times.
Other branches: There are other shops around the city, including one at a department store. Check the official Sungsimdang channels for the current list.

What people buy

The two breads you will see in almost every basket are twigim soboro, a fried bun with a crumbly peanut topping and a sweet red-bean filling, and buchu-ppang, a savory bun filled with chives. Sungsimdang is also known for big seasonal cakes, which change through the year and draw their own queues. Popular items can sell out later in the day, so go in the morning if you have a specific bread in mind.

Opening hours differ by branch and change from time to time, so check the official Sungsimdang website or social media pages on the day.

Afternoon: Expo Science Park and Hanbit Tower

Daejeon hosted the World Expo in 1993, and the site is now Expo Science Park on the north side of the Gapcheon stream. The grounds are free to walk, and they make a relaxed, open break after the busy bakery.

Hanbit Tower: The Expo's symbol, a tall tower with an observation deck. You can go up for a small fee and see over the park and the city. Check current hours and fees on site.
Expo Bridge: A footbridge over the Gapcheon stream, popular at sunset and lit up at night.
Riverside paths: The Gapcheon banks have long walking and cycling paths if you want a quiet stroll.
Shopping and food: A large modern shopping and leisure complex sits next to the park, which is handy for a meal, coffee or rain.

Daejeon is also known in Korea as a "science city" because of the Daedeok research district nearby. The National Science Museum is close to the Expo area, which is a good extra stop for families.

How to get there

From the old downtown, the easiest way is a taxi of roughly 20–30 minutes depending on traffic. You can also ride Daejeon Metro Line 1 toward Banseok and then take a bus or a short taxi from a station near the park. Daejeon's metro is a single line and simple to use with a T-money card. Naver Map or Kakao Map will give you the best current route.

Evening: Yuseong hot springs and the free foot bath

Yuseong has been a hot-spring town for centuries, and today it is a district of hotels, spas and saunas a little west of the Expo area. Yuseong Spa Station on Line 1 drops you right in the middle of it.

Yuseong Foot Spa

The highlight for visitors is the open-air Yuseong Foot Spa, a public foot bath fed by natural hot-spring water. It is free, needs no ticket or booking, and is a lovely way to rest tired feet after a day of walking. Bring a small towel, as there is nowhere to buy one at the bath itself. Hours vary by season and the bath may close for cleaning, so check before you go.

Full spa or sauna

If you want a proper soak, several hotels and public bathhouses in Yuseong let day visitors use their hot-spring baths for an entry fee. Korean bathhouses are usually separated by gender and require bathing nude, so read our tips below if it is your first time.

Sample one-day itinerary

Morning: Early KTX from Seoul Station to Daejeon Station.
Late morning: Subway one stop to Jung-ang-ro, queue at the Sungsimdang main store, then walk the old downtown streets.
Lunch: Eat near Eunhaeng-dong. Daejeon is known for kalguksu (knife-cut noodle soup), and you will see many noodle shops around downtown.
Afternoon: Taxi to Expo Science Park, go up Hanbit Tower, and walk across Expo Bridge.
Early evening: Go to Yuseong for the foot bath or a spa.
Night: Back to Daejeon Station, pick up bread at the station branch if you missed the main store, and take the KTX home.

If you have a second day, the presidential villa at Cheongnamdae is a classic side trip. See our guide on how to visit Cheongnamdae from Seoul or Daejeon.

Staying connected on the day

You will lean on your phone for train tickets, map apps and bakery queues. If you do not have data yet, a local SIM or eSIM makes the day much easier. For example, the Korea unlimited data SIM on KKday can be picked up at the airport when you arrive.

Quick tips

Book your KTX return before you leave Seoul, especially on weekends.
Make sure your ticket says Daejeon (대전), not Seodaejeon (서대전).
Visit Sungsimdang early. Popular breads sell out and lines grow through the day.
Carry a small towel for the Yuseong foot bath.
Use Naver Map or Kakao Map. Google Maps transit directions in Korea are limited.
Check hours for every stop on the day, since they change by season.
