Seongsan Ilchulbong and Dongmun Market: Where Sea and People Meet on an Island Shaped by Volcanoes
At the easternmost tip of Jeju stands a massive tuff cone rising above the sea—Seongsan Ilchulbong. Formed about 6,700 years ago when magma erupted through shallow seawater, this hydrovolcanic formation is named 'Seongsan' (城山, 'Castle Mountain') because its rocky peaks encircle the crater like fortress walls. At 182 meters above sea level, this peak was inscribed on the UNESCO World Natural Heritage List in 2007 under the name 'Jeju Volcanic Island and Lava Tubes,' alongside the Hallasan Natural Reserve and the Geomunoreum Lava Tube System. Because the terrain rises facing east, the sunrise viewed from the summit is especially beautiful, which is why the name 'Ilchulbong' (Sunrise Peak) was added, and since ancient times, 'Seongsan Ilchul' (Sunrise at Seongsan) has been counted among the Ten Scenic Views of Jeju. You can climb to the summit along the trail that follows Jeju Olle Trail Course 1. Viewed from the shore, Seongsan Ilchulbong looks like a massive fortress, and from the summit, the entire crater and surrounding coastline come into view at once. The terrain is volcanologically unique, and as you walk, you're reminded anew that all of Jeju Island is the product of volcanic activity. Searching for Seongsan Ilchulbong on a map will immediately show the trail entrance, ticket office location, and parking information. Driving from Seongsan Ilchulbong brings you to Dongmun Traditional Market in the heart of Jeju City. Established after the Japanese colonial period, this market was destroyed by fire once in 1954 but was rebuilt on the same site under the same name. It remains the largest and oldest surviving permanent traditional market in Jeju, where you can find fresh seafood alongside Jeju specialties like Hallabong and other citrus fruits, street food, and souvenirs. Behind the market lies the Dongmun Night Market, where food trucks gather, giving the area a distinctly different atmosphere by day and by night. Located on Gwandeok-ro 14-gil, it's also a great spot for exploring Jeju City's old downtown area. The two places reveal different faces of the island. Seongsan Ilchulbong is a record left by nature through volcanic activity thousands of years ago, while Dongmun Market is a record of daily life built by people on that island. Linking the two together as a one-day course on the map lets you experience both the natural and human textures that Jeju holds.
Visit Tips
The trail at Seongsan Ilchulbong includes outdoor stairs and an uphill path, so comfortable shoes are recommended. Operating hours, last admission times, and admission fees may change depending on the season and policy, so it's advisable to check the latest information on the official Visit Jeju website before your visit. At Dongmun Traditional Market, business hours vary slightly by shop and there may be regular closing days, so if you're going specifically for seafood or certain foods, it's safer to check same-day operation status through official channels or local guidance. Both locations connect to the Jeju Olle Trail or public transit routes, so checking your route in advance with a map app will make getting around easier.
