Daejeon is Korea’s fifth-largest city and its designated science and technology hub, sitting at the geographic centre of the Korean peninsula.
It is not a primary tourist destination, but it has enough to fill a half-day or full day, particularly the Expo Science Park (built on the 1993 World Expo site), Gyeryongsan National Park, and the Yuseong hot spring district. Its central position also makes it a natural transit stop between Seoul and Busan.

What to Do in Daejeon
Expo Science Park
Built on the site of the 1993 Daejeon World Expo, the park has science museums, outdoor science installations, and the Hanbitgol Lake at its centre. The Expo Science Center has interactive science exhibitions popular with families. The Expo Tower (93 metres) has a viewing platform—entry: approximately 5,000 to 8,000 won, depending on which attractions. The park is particularly pleasant in spring and autumn for the lakeside walks.
Gyeryongsan National Park
A national park approximately 25 kilometres southwest of central Daejeon, accessible by bus (approximately 40 minutes from Daejeon Station). Gyeryongsan (the mountain’s name translates roughly as Rooster Dragon Mountain) has granite peaks, Buddhist temples, and hiking trails. The main temple, Magoksa (approximately 30 minutes farther by bus from the park entrance), is a UNESCO World Heritage Site among the Silla Buddhist mountain temples. Hiking from the main entrance to the summit ridge takes approximately 2 to 3 hours return.
Yuseong Hot Spring District
Daejeon’s Yuseong neighbourhood has Korea’s most historically significant hot spring district, featuring mineral-water spas and jjimjilbang bathhouses. The Yuseong Hotel spa (open to non-hotel guests) and several public bathhouses serve the naturally occurring bicarbonate mineral spring. A spa session at Yuseong is a good reason to add an overnight to a Daejeon visit rather than a day trip.
Hanbat Arboretum
One of Korea’s largest urban arboretums is in the western part of Daejeon city. Extensive walking paths through themed garden sections, including a rose garden (best in May), a Japanese garden, and an ecological wetland zone. Free entry. Particularly good in spring and autumn.
Daejeon O-World
A zoo and amusement park combined in one large facility, popular with Korean families. Good for visitors travelling with children. Entry approximately 15,000 to 20,000 won.
What to Eat in Daejeon
Daejeon is particularly known for two dishes. Sikhaeyori (spicy fermented skate, a local delicacy for adventurous eaters) is found at traditional restaurants near Jungang Market. More accessible, Daejeon’s take on seolleongtang (milky ox bone soup) is considered among the best in Korea. The Jungang Market in central Daejeon has good street food and traditional market restaurants. See the Korean food guide.
Daejeon as a Day Trip from Seoul or Busan
The 50-minute KTX from Seoul makes Daejeon very accessible as a day trip. Gyeryongsan and the Expo Science Park together make a reasonable day. For those on the Seoul-to-Busan corridor, Daejeon is an easy stop to break the journey. See the Seoul-to-Daejeon guide for transport details.
