Jejuで知っておきたいこと
- Jeju is an island and self-governing province rather than a city, and its airport sits inside Jeju City on the north coast.
- Jeju International is the second-largest airport in South Korea after Incheon, handling both domestic and international routes, so it is a busy arrival point despite serving an island.
- Jeju's public wifi network is called Jeju Free Wifi. Its own guide gives three steps: select the network, register usage information, then pass a promotional screen before browsing.
- By August 2020 Jeju Free Wifi covered about 4,644 hotspots, including Hallasan's summit and rest areas and Seongsan Ilchulbong, plus roughly 932 public buses.
- Jeju Free Wifi later reached the Witseoreum and Seongpanak rest areas on Hallasan and piloted Wifi 6 at Seongsan Ilchulbong, with plans to extend to ferries and the islands of Udo and Chuja.
- Since August 2025 Jeju buses take EMV tap payments from overseas issued Visa credit, debit and prepaid cards, so a visitor can ride without a T-money card or Korean won cash.
- Jeju buses had run since 1997 on PayOn, a closed loop system that obliged visitors to buy and top up a separate T-money card in Korean won before travelling.
- At Jeju International Airport, city and intercity buses leave from Gate 2 and taxis from Gate 3 across a crosswalk, according to Korea's official Airportal aviation information system.
- Jeju International Airport has two runways, a 3,180 by 45 metre main runway and a 1,900 by 45 metre secondary, with CAT II instrument landing at one end, per Korea's Airportal system.
- Jeju airport is rated for roughly 172,000 flight movements a year and can park up to 42 aircraft at once, according to Korea's Airportal data.
- Jeju is tied to mainland Korea by undersea HVDC cables, the roughly 101 km Haenam to Cheju link from 1996 and the 105 km Jindo to Jeju link from 2014.
