Getting to the start
Jeju Airport
제주공항
Public transport here is genuinely awkward. Allow extra time.
About 1h10 in the air from Gimpo to Jeju. From Jeju Airport to Seongsan is over an hour by bus. Buses on Jeju are infrequent, which is why most visitors rent a car — it can be done on public transport, but check the timetable first if you want both sites in one day.
The route
- 1
Seongsan Ilchulbong
Seongsan, Seogwipo · 2hA volcanic crater that rose straight out of the sea, listed as a UNESCO World Natural Heritage site. Twenty to thirty minutes of steps put a 600-metre-wide crater under your feet. It is famous for sunrise, as the name says — which means sleeping nearby.
- Bus45m
West along the coast road, about 45 minutes. By bus it usually means a change and takes longer. Inside the cave it stays between 11 and 21°C and the floor is wet — bring a layer and decent shoes.
2Manjanggul Cave
Gujwa, Jeju · 1h 30mA lava tube left by flowing magma, part of the UNESCO natural heritage listing. The open kilometre ends at a lava column 7.6 metres tall. Inside it stays between 11 and 21°C year-round and the floor is wet and slippery — bring a layer and decent shoes.

Good to do next
- Seopjikoji & Bijarim ForestEast Jeju · Full day
Start on a grassland headland running into the sea and finish inside a forest of five-hundred-year-old trees. On Jeju's east side these two are as different as it gets.
- Dongmun Market Half-DayJeju City · Half day
The island's biggest permanent market, close enough to the airport to fit into an arrival or departure day.
- Seogwipo Falls & the Lava CliffSeogwipo, Jeju · Half day
A waterfall you reach on foot from town, and a cliff of hexagonal columns where lava met the sea. On Jeju's south coast this is the pairing with the least walking.
