Jeju Island
A volcanic holiday island where you can climb Korea's highest mountain in the morning and eat what the haenyeo divers brought up that afternoon.
Jeju is a volcanic island off Korea's south coast, built up around Hallasan, the country's highest mountain, and ringed by lava cliffs, black-sand beaches and a waymarked walking route that circles the whole thing. Koreans have treated it as their holiday island for generations, for honeymoons, family trips and long weekends, and the pace slows to match. Underneath is a culture of its own: a separate dialect, stone grandfather figures, dry-stone walls built against the wind, and the haenyeo, women who free-dive for shellfish into old age.

Why you'll love Jeju Island
The volcano a shield mountain with a crater lake at the top, hundreds of small parasitic cones scattered across the slopes and lava tubes running underneath
The coast basalt columns, tuff cones, white-shell and black-sand beaches, and a coastal footpath that links the lot in walkable stages
The haenyeo free-diving women who still work the shallows for abalone, conch and sea urchin without tanks, and sell the catch at the water's edge
Eating black pork grilled over charcoal, abalone porridge, hairtail stew and tangerines picked off the tree in winter

When to avoid Jeju Island
August is the month to dodge: hot, sticky and the peak of the Korean summer holidays, when flights fill and the beach towns are at their busiest. Typhoons are possible from midsummer into early autumn and can ground flights and cancel the island ferries for a day or two. Wind, though, is a constant here rather than a season.
Top things to do in Jeju Island
-
Hallasan - the summit trails to Baengnokdam
hiking nature wildlife 👍 PopularThe shield volcano the whole island is piled around, topped by Baengnokdam, a crater that holds a shallow lake after rain. Only the Seongpanak and Gwaneumsa trails reach the rim; both are long walks rather than climbs, both need an advance online reservation, and rangers turn people back at the checkpoints after a cut-off time that moves with the season.
-
Seongsan Ilchulbong - the sunrise tuff cone
scenic nature wildlife 👍 PopularA crater blown out of the sea by a shallow eruption, now joined to the east coast by a sand bar, with a stepped path up the outer wall to a bowl of grass at the top. It is the island's postcard, and the name means sunrise peak for a reason. Haenyeo dive off the rocks below.
-
Manjanggul - walking inside a lava tube
nature wildlife 👍 PopularPart of the Geomunoreum tube system and one of the finest lava caves anywhere: a cold, dripping tunnel wide enough to drive through, with lava shelves along the walls and a towering lava column at the far end of the open section. Bring a jacket, the temperature barely moves all year.
-
Jeju Olle Trail - the coastal route around the island
hiking scenic ⭐ Highly recommendedA numbered set of walking routes strung end to end around the coastline and out onto a few of the offshore islands, marked with blue and orange ribbons and a small stone pony. Each stage is a comfortable day and ends somewhere with a bus stop, so you can walk one and skip the rest without guilt.
-
Haenyeo - the diving grandmothers and the seafood shacks
culture arts food ⭐ Highly recommendedJeju's divers are mostly women now in their sixties and older, working the shallows on a held breath in wetsuits and lead belts. Their culture is on the UNESCO intangible heritage list. You can watch them surface off the east coast, see the small museum near Hado, and eat conch and sea urchin at the huts by the landing rocks.
-
Jusangjeolli Cliffs - hexagonal basalt at Jungmun
scenicA wall of columnar basalt on the south coast, cracked into hexagons as the lava cooled and now taking the swell head-on from a boardwalk above. Short, spectacular and ten minutes from the Jungmun resorts.
-
Jeongbang and Cheonjiyeon falls - waterfalls at Seogwipo
scenic nature wildlifeJeongbang drops straight off a cliff into the sea, one of very few waterfalls in Asia that does. Cheonjiyeon and Cheonjeyeon, both a short drive away, fall into pools in subtropical gorges thick with ferns, and all three sit close enough to Seogwipo town to string together in an afternoon.
-
Black pork - heukdwaeji over charcoal
foodThe island's native black-haired pig, grilled thick at the table and eaten with anchovy sauce rather than the usual sesame oil. Jeju City has a whole street of it near the old town, and most visitors eat it at least once.
-
Seongeup Folk Village - thatch and dry-stone lanes
culture arts historyA living village on the mid-slopes that kept its old form: thatched roofs roped down against the wind, black lava walls, stone gates with sliding poles that say whether anyone is home, and a pair of stone grandfathers at the entrance. People still live here, so it is quieter than it looks.
-
Sanbangsan and the Yongmeori coast - a lava dome over folded cliffs
scenic nature wildlifeA blunt dome of viscous lava standing alone above the southwest coast, with a grotto temple cut into its flank. Below it the Yongmeori headland folds into layered sandstone ledges you can walk when the tide and the sea allow, which is not every day.
-
Seogwang tea fields - green tea on the volcano's flank
food scenicRows of tea planted across the western mid-slopes on volcanic soil, with a tea museum and cafes at the edge of the fields. It is the reason Jeju green tea turns up in everything on this island, ice cream and cheesecake included.
-
Bijarim and Saryeoni - forest walks
nature wildlife hikingBijarim is a dense stand of ancient nutmeg yews, some of them many centuries old, on flat gravel paths. Saryeoni is a straight cedar avenue on the road between Jeju City and the east, and both are cool, easy walking on a hot or wet day.
-
The oreum - climbing the small cones
hiking scenicHundreds of parasitic cones stud the slopes between the coast and Hallasan, most of them a twenty-minute climb to a grass crater and a view over the rest. Yongnuni, Darangshi and the ridge at Saebyeol are the ones locals send you to, and sunset is the hour.

Getting to & around Jeju Island
Getting there
Fly into Jeju City, then pick up a rental car or a bus at the terminal
Flight
Jeju International Airport (CJU)
The airport sits on the western edge of Jeju City, so arriving is minutes rather than a journey: city buses reach downtown and the ferry port in about a quarter of an hour, and airport buses run down both coasts to Seogwipo and the Jungmun resorts in roughly an hour. Most visitors collect a rental car from the lots just outside the terminal.
Ferry
Jeju Port
Car and passenger ferries cross from Mokpo, Wando, Yeosu and Busan, taking a few hours from the near ports and overnight from the far ones
Ferry
Seongsan Port
A smaller east-coast port with services from Nokdong on the mainland, handy if you are driving down the south coast
Getting around
Rental car
How almost everyone does it. Roads are good, the ring road laps the island, and parking is easy outside Jeju City
TBC
Bus
A rebuilt network of express, trunk and village routes covering the coast and the two cross-island roads; workable but slow
TBC
Taxi
Easy in the two cities and at the resorts, thin in the villages; app-hailing helps but drivers can be scarce on the east coast
TBC
Bicycle
A signed cycle route runs the full coastal ring, roughly a four-day loop, with the wind deciding which way round you go
TBC
Walking
Fine within Seogwipo, Jeju City and the Olle stages, useless for getting between sights on an island this size
Free
Day trips from Jeju Island
Udo
Full dayIsland off the island
A flat green island of stone walls, peanut fields and low cliffs, small enough to loop in a day. The draws are a beach of white coral fragments, the lighthouse headland, more haenyeo working the shallows, and peanut ice cream at every second stall. Sailings stop when the wind gets up.
Getting there
ferry | bus | car
About 15 min by ferry from Seongsan Port, then a rented buggy, bike or the island bus
Hallasan summit
Full dayVolcano summit hike
The island's headline walk and a genuine full day. Seongpanak is the longer, gentler side; Gwaneumsa is steeper and better looking. Both need an advance reservation and both enforce turnaround times at the checkpoints. Snow and crampons are normal in winter, and cloud swallows the crater more often than not.
Getting there
car | bus | walk
About 40 min by car or bus to the Seongpanak or Gwaneumsa trailhead, then a long day on foot
Gapado and Marado
Half daySouthernmost islands
Two tiny islands off the southwest. Gapado is barley fields and footpaths with Sanbangsan and Hallasan filling the view back north. Marado is the southernmost point of South Korea, an hour's walk end to end, known for jajangmyeon noodles served at the bottom of the country. Both cancel in rough weather.
Getting there
ferry | walk
About 15 to 30 min by ferry from Moseulpo on the southwest coast
The east coast loop
Full dayCoast, cones and lava tubes
The classic circuit: the sunrise tuff cone at Seongsan, the flowering headland at Seopjikoji, the beaches at Woljeongri and Hamdeok, Manjanggul's lava tube and the grass craters of the Darangshi oreum inland. Add the folk village at Seongeup on the way back over the middle.
Getting there
car | bus
A day's driving from either city, roughly an hour each way
The southwest coast
Full dayLava dome and tea fields
Sanbangsan's lava dome and grotto temple, the folded ledges of the Yongmeori coast beneath it, the crater walk at Songaksan looking out to Marado, and the Japanese-built airfield bunkers behind the dunes. Finish inland among the Seogwang tea fields.
Getting there
car | bus
About an hour by car from Seogwipo, longer by bus
A little history of Jeju Island
Jeju was its own place long before it was Korean. The kingdom of Tamna traded with the mainland and with Japan as a tributary and was only absorbed by Goryeo in the early twelfth century. Its founding story still has three demigods rising out of holes in the ground to marry three princesses who arrived by sea with grain and livestock. In 1273 the island became the last stand of the Sambyeolcho rebels, and after the Mongols crushed them they held it for a century as a horse pasture. Under Joseon it was where the capital sent people it wanted out of the way.
The twentieth century was brutal. Japan fortified the island as an air and naval base, and in April 1948 an uprising against the coming division of Korea triggered a counter-insurgency that killed tens of thousands and burned villages off the mid-slopes. It could not be spoken about publicly until the 1990s. What came after was tangerines and tourism: groves that paid for children's schooling, honeymooners on the newly reachable island, and eventually UNESCO listings for the volcano, the lava tubes and the divers.

FAQs about Jeju Island
▸ When is the best time to visit Jeju?
April, May, October and November. Spring brings the canola fields around the sunrise peak and cherry blossom in Jeju City; autumn is clear and the best walking of the year. August is hot, humid and busy with Korean holidaymakers. Winter is windy but mild at sea level, with camellias out and tangerines on the trees.
▸ How many days do you need on Jeju?
Three days covers one coast, one island and a decent share of the volcano's landscape. Five lets you lap the whole ring road without rushing, give Hallasan its own full day, and still spend one doing nothing at a beach or a cafe.
▸ Do you need a car on Jeju?
Practically, yes. The sights are spread around a ring road and the buses, while comprehensive and cheap, turn a two-hour circuit into most of a day. If you would rather not drive, base yourself in Seogwipo or Jeju City and use buses, taxis and the Olle stages instead.
▸ Can you climb Hallasan without hiking experience?
Yes. Both summit trails are long walks on maintained paths and stairs rather than climbs, but they are a full day and the weather at the top is not the weather at the coast. Book the reservation in advance, start early, and expect to be turned back if you miss the checkpoint cut-off.
▸ Is Jeju expensive?
It costs more than the mainland for the same thing, because most of it is shipped in and demand is domestic and seasonal. Accommodation and rental cars are where you feel it, especially in August. Buses, market food and almost every natural sight stay cheap.
▸ What is Jeju food known for?
Black pork over charcoal, abalone in porridge and stews, grilled hairtail, raw and grilled conch from the haenyeo, and buckwheat noodle dishes you do not see elsewhere in Korea. Then the tangerines, hallabong especially, which turn up as juice, chocolate and cake all over the island.
