Jeju City

Jeju City (Korean: 제주시, romanized: Jeju-si; Korean pronunciation: [tɕe̞.dʑu]) is the capital of the Jeju Province in South Korea and the largest city on Jeju Island. The city is served by Jeju International Airport (IATA code CJU).
Located on an island off the Korean Peninsula, Jeju has mild, warm weather during much of the year. The city is a well-known resort, with prestigious hotels and public casino facilities. In 2011, 9.9 million passengers flew between the two cities of Seoul and Jeju, making the Gimpo–Jeju route the world's busiest passenger air route.
Jeju welcomes over ten million visitors every year, mainly from the South Korean mainland, Japan, and China. The population of Jeju City is 486,604 people and 225,139 households (244,468 men and 245,136 women, May 2024). The population density is 503.18 (per square km, 2020).
The area of the city has played a central role in Jeju since before recorded history. The Samseonghyeol, holes from which the three ancestors of the Jeju people are said to have come, are located in downtown Jeju City.
During the Japanese rule of Korea, Jeju was renamed to Saishū.
The city has grown quite rapidly since the 1970s. Shin Jeju (신제주), or "new Jeju", was created some decades ago, up the hill from the airport and houses many government buildings. The thatched roof buildings that were common throughout the city until the 1970s are gradually disappearing.
The city was separated from Bukjeju County in 1955. However, in 2005 Jeju Province voters approved a proposal to merge the city with Bukjeju County, also merging Seogwipo with Namjeju County to create two large cities directly administered by the province. That change was put into effect in July 2006.
In 2012 Sang-Oh Kim became mayor; he was formerly the Jeju regional president of National Agricultural Cooperative Federation.
Jeju City is the principal transportation center for Jeju Province. It is home to the island's sole airport, Jeju International Airport. The Jeju-Seoul route is the world's busiest air route with more than 100 flights per day.
In addition, its port is the largest on the island, serving the great majority of passenger and cargo vessels that visit the island. It also stands at the center of the island's road network. To travel throughout the city and island, various buses are available. A bus ride from Jeju City to Seogwipo (the second largest city on the island) is typically an hour.
Due to its central position in transportation, Jeju City sees the main share of tourist traffic to the island. Many tourists arrive at the city through the port terminal or airport, stay in the tourist hotels of the Sinjeju neighborhood, and stay within the city to visit various Jeju tourist attractions. These include Dragon's Head Rock (Yongduam [ko]) along the coast; the Samseonghyeol, three holes in the downtown area; Hallasan National Park in the interior; the country's tallest mountain, Hallasan; and world's largest botanical garden, Bunjae Artpia. The 8,500-seat Jeju Baseball Stadium is near the center of the city.
The city also sells many oranges for which Jeju is famous. Jeju City is surrounded by orange and mandarin farms.
Jeju Air has its headquarters in Jeju City.
In its former boundaries, Jeju City was 19.3 kilometers from east to west, and 10.2 kilometers from north to south. To the north, it looks across the Korea Strait at the southern coast of South Jeolla Province. To the south, it meets Seogwipo at the top of Hallasan, the island's sole mountain.
The Jeju Olle Trail and Jeju Olle Walking Festival passes through the city.
The island Udo, one of Jeju's most popular tourist attractions, is located off the city's east coast. It received 2.23 million visitors in 2016. Seongsan Ilchulbong, an unusually bowl-shaped mountain, is popular for seeing the first sunrise of the year. Around that time, it hosts a sunrise festival with performances and food.
The city has Jeju Stone Park in Jocheon. The large park focuses on Jeju's cultural use of stones, its mythology, and its shamanism. The Jeju National Museum is located in the city proper, near the center. The Kimnyoung Maze Park is in the city. The Buddhist temple Yakcheonsa has a natural mineral spring claimed to have healing powers, and is one of the largest temples in East Asia. It participates in the Templestay program, where guests can stay at Buddhist temples and experience Buddhist culture.
Manjanggul Lava Tube is one of the longest lava tubes in the world and a UNESCO World Natural Heritage site. Inside, visitors can explore a section of the cave featuring stalactites, lava columns, and other geological formations created by ancient volcanic activity.
Cheonjiyeon Waterfall is located near Seogwipo and is known for its picturesque setting, subtropical plants, and legend-associated name meaning “heaven and earth meet.” The area is well-lit at night, making it a popular spot for evening visits and photography.
Camellia Hill is a large botanical garden located in the southwestern part of Jeju Island. It is known for its extensive camellia flower collection, with over 500 species on display, as well as seasonal flower exhibitions and themed photo zones.
Yongmeori Coast features dramatic volcanic rock formations shaped by thousands of years of erosion along Jeju’s southern shoreline. The walking path hugs the cliffside and reveals fossil-rich strata, creating one of Jeju’s most geologically unique coastal experiences.
