Stand on the coastal path at Yongdam and the first thing you notice is how the black volcanic rock has been worn into shapes that look deliberate: a dragon's head at Yongduam Rock, a turquoise pool below a pavilion at Yongyeon Pond a hundred metres east. Jeju City works like that — a working provincial capital where the sights sit close to ordinary streets, and where the sea, the stone and the old downtown are all within a short ride of each other.
It suits travellers who want a base rather than a resort: people arriving at Jeju International Airport and staying in the Sinjeju neighbourhood, people using the city's buses and port to reach the rest of the island, and people who would rather spend a morning in a museum or a forest than queue for an attraction. Weather is mild for much of the year, wetter in summer, and cool enough in winter for snow showers.
This guide covers the places in and around Jeju City that are worth building a day around, followed by a one-day plan and answers to the questions visitors ask most.
Top things to do in Jeju City
1. Yongduam Rock and Yongyeon Pond
A large piece of volcanic rock on the coast at Yongdam, said to be the solidified remains of Yimugi, a water dragon — the surrounding suburb takes its name from it. About 100 m to the east is the lesser known but prettier Yongyeon Pond, a canyon straddling a turquoise pond with a pavilion perched overhead, where a dragon also features in the legends.
Both sites are lit up at night, so consider coming after dark if you want the spectacle rather than the daylight view. A festival is held here in May. You can wander over from downtown or Tapdong, or take the #36, #37, #63, #300 or #500 to Yongdam Junction and walk. Note that an old man out the front offers horse rides for a fee, persistently.
2. Jeju Old Government Offices
A set of Joseon-era historical buildings in central downtown Jeju City, reached by following the signs to the wooden gate. What sets the complex apart is a nicely landscaped square pond, and a history that includes being built in lieu of a well, then destroyed over a dislike of noisy frogs, and ultimately rebuilt.
It is an easy pairing with the downtown sights, including Samseonghyeol, which is also on Samseong-ro. Entry is ₩1500, and free if you are wearing Korean traditional dress.
3. Samseonghyeol
A revered site in downtown Jeju City featuring three mythical holes, believed to be the origin of the island's mythical founders. The Samseonghyeol are the holes from which the three ancestors of the Jeju people are said to have come, which gives the site a central place in how the city understands itself.
It sits on Samseong-ro, close to the Jeju Folklore and Natural History Museum, so the two work well as one stop. Entry is ₩4,000, and it is open 09:00-18:00.
4. Jeju National Museum
A history museum of Jeju Island's historical and cultural assets, near the centre of the city proper. It houses remains excavated from ruins, including relics from the prehistoric age through to the Joseon dynasty.
It is free and open 09:00-18:00, but closed on Mondays, so plan it for another day if your trip starts at the beginning of the week.
5. Jeju Folklore and Natural History Museum
Divided into four exhibition halls — natural history, folklore, special resources and an audio-visual room — this museum covers the island's natural history along with relics, animals and plants found around Jeju. The stuffed animals are popular with children.
It is on Samseong-ro, which makes it a natural companion to Samseonghyeol. Entry is ₩2,000, and it is open 09:00-18:00, closed on Mondays.
6. Jeju April 3rd Peace Park
A museum about the mass killing of Jeju islanders by government forces on 3 April 1948, part of the 1948-49 Jeju Uprising. It is a sober, serious stop rather than a light one, and it gives context to the island that the coastal sights do not.
It is free and open 09:00-18:00. Allow time afterwards rather than scheduling something immediately after.
7. Iho Tewoo Beach
Close to Jeju International Airport and near enough to reach by bicycle, this beach has white and red pony lighthouses, a gentle slope and a pine forest nearby. It is a good place for scenery and an easy walk rather than a full day out.
Because of its position near the airport, it fits neatly at the start or end of a trip, or as a stretch of the legs before a flight.
8. Halla Arboretum
Home to nearly 1,100 species of plants, including native Jeju flora and exotic subtropical species. It is free, with outdoor hours of 09:00-23:00 and indoor hours of 09:00-18:00.
The late outdoor closing makes it one of the few green spaces you can visit in the evening. It pairs well with the city's other free sights if you are keeping costs down.
9. Jeju Jeolmul Recreational Forest
A forest of both natural Japanese cedar and man-made planting, opened on 23 July 1997. It has a promenade, a waterfall, a pond, a grass square and a wood-crafting studio, and forest cabins are available for lodging.
Entry is ₩1000 and it is open 07:00-18:00, so an early start gives you the quietest walking. Staying in one of the cabins is an option if you would rather not return to the city each night.
10. Gwaneumsa Temple
A historic Buddhist temple on the slopes of Hallasan Mountain. It is free to visit and makes a calm counterpoint to the downtown sights.
Because it sits on the mountain slopes, treat it as a half-day rather than a quick stop, and combine it with the mountain side of the island rather than the coast.
11. Bijarim Forest
A forest of old-growth nutmeg trees, walked on flat gravel paths. In the centre stands a Japanese Torreya tree more than 800 years old, the oldest tree on Jeju. There are two connected walking paths: the short trail takes about 30 minutes and the longer loop perhaps double that.
Entry is ₩3,000. The flat paths make this one of the more accessible forest walks, and the two-trail layout lets you decide how much time to give it.
12. Haenyeo Museum
A small but interesting museum dedicated to the Haenyeo, the female divers, with nice views from the top. It is open Tuesday to Sunday, 09:00-18:00, and closed on Mondays.
Entry is ₩1,100. It sits in Hado-ri in Gujwa-eup, on the eastern side of the city's area, so pair it with other eastern stops rather than crossing back and forth.
13. Manjanggul Cave
A famous lava tube and a UNESCO-listed world natural heritage site. The interior has lava stalactites on the ceiling and lava wings on the wall, and the 7.6-metre-high lava stone pillar at the end of the open section is the largest in the world. It is protected as a natural monument along with nearby Gimnyeong Cave.
It is closed until 31 December 2025, so check before you build a day around it. Entry is ₩2,000 when it is open.
14. Gimnyeong Snake Cave
A 700-metre-long S-shaped lava tube, also called snake cave for its internal shape. The entrance bulges like a head of a snake and becomes thin as you go deeper.
It is in Gimnyeong-ri in Gujwa-eup, the same eastern area as Manjanggul Cave and the Haenyeo Museum, so group them if you are heading that way.
15. Bangae Oreum
An oreum with four peaks in the west and southeast and a flat southern side, with grassland in the crater. It is a short, quiet walk rather than a major hike.
It sits in Gyrae-ri in Jocheon-eup, which makes it a reasonable addition to a day spent on the eastern side of the city.
If you only have one day
Morning. Start downtown at Samseonghyeol, then walk to the Jeju Old Government Offices nearby. Follow with the Jeju Folklore and Natural History Museum on Samseong-ro, or the Jeju National Museum if you would rather have the island's broader history — remember both are closed on Mondays.
Afternoon. Head to the coast at Yongduam Rock and walk the hundred metres east to Yongyeon Pond. If time allows, take a bus or wander over from downtown or Tapdong, and add Iho Tewoo Beach on the way back towards the airport for the pony lighthouses and the pine forest.
Evening. Return to Yongduam Rock and Yongyeon Pond, both of which are lit up spectacularly at night. If you would rather end among trees, Halla Arboretum keeps its outdoor areas open until 23:00.
Frequently asked questions
How do I get to Jeju City?

Do I need a car to get around?
Various buses are available to travel throughout the city and the island, and the city stands at the centre of the island's road network. As a comparison for planning, a bus ride from Jeju City to Seogwipo typically takes an hour.
Which days are museums closed?
The Jeju National Museum and the Jeju Folklore and Natural History Museum are both closed on Mondays. The Haenyeo Museum is closed on Mondays as well, and open Tuesday to Sunday, 09:00-18:00.
Is Manjanggul Cave open?
No — Manjanggul Cave is closed until 31 December 2025. If your trip falls before then, plan the eastern side of the city around Gimnyeong Snake Cave, Bangae Oreum and the Haenyeo Museum instead.
Pick the sights that match your days, check the Monday closures against your dates, and start laying out your Jeju City itinerary.
