Jeju Island: Tickets, Hours and How to Visit
Jeju’s marquee sights are the actual reason to book this island over a mainland Korea trip: a UNESCO tuff cone you climb before breakfast, a lava tube stretching into the dark, and a dormant volcano with its own reservation system. Skip the theme-park glut around Jungmun (Loveland, the Teddy Bear Museum, and a dozen similar novelty stops), the real draw here is volcanic and coastal, not kitsch. Here’s what each headline sight actually costs, how long it takes, and what catches visitors off guard.
Jeju’s marquee sights ranked
| Sight | Area | Why go | Cost + time |
|---|---|---|---|
| Seongsan Ilchulbong | East (Seongsan) | UNESCO tuff cone, crater rim views, Jeju’s most-photographed sunrise | |
| Manjanggul | East (Gujwa) | UNESCO lava tube, ~1km of a 7km+ system, cool year-round at 11-18C | |
| Hallasan (Baengnokdam summit) | Central | South Korea’s highest peak, 1,947m, the crater lake at the top | Free entry; summit trails need a reservation at visithalla.jeju.go.kr; 8-10 hours round trip |
| Jusangjeolli | West (Daepo, near Jungmun) | Hexagonal basalt columns where Hallasan’s lava met the sea | |
| Cheonjiyeon Falls | South (Seogwipo) | An easy, scenic waterfall walk right from central Seogwipo | |
| Jeongbang Falls | South (Seogwipo) | One of the few waterfalls in Asia that drops straight into the ocean | Nominal entry; 30 minutes |
| Haenyeo Museum | East (Gujwa) | The real story behind Jeju’s free-diving women, UNESCO intangible heritage | |
| Udo Island | East (ferry from Seongsan) | A ~15-minute ferry to its own beaches, cycling loop, and peanut ice cream | |
| Hyeopjae Beach | West | Turquoise water and pale sand, the most photogenic swim on the island | Free; swim only at the patrolled section |
Paying to get in
Is Manjanggul lava tube open right now?
Yes, as of this writing. It reopened 30 May 2026 after a rockfall closure that ran from December 2023, with new observation decks and lower-intensity lighting to curb algae growth. Entry is about 4,000 KRW (~$3) adult, hours run roughly 9am-6pm with the ticket booth closing around 5pm. A reopening this recent can still see short follow-up closures, confirm current status before you build a day around it.
Do you need a reservation to summit Hallasan?
Usually, yes, for the two trails that actually reach the Baengnokdam crater rim, Seongpanak and Gwaneumsa, booked free at visithalla.jeju.go.kr and capped at roughly 1,000 and 500 hikers a day. The park has periodically suspended this requirement for limited seasonal windows while keeping the same descent cutoffs, so check the live rule rather than assuming either “always” or “never.” Four other trails, Eorimok, Yeongsil, and Donnaeko among them, reach high viewpoints with no reservation needed.
Book a base near the east coast sights before the good rooms go, check Jeju City hotel rates on Booking.com . For Seongsan, Manjanggul, and the Haenyeo Museum in one booked day, browse an east coast UNESCO day tour on GetYourGuide rather than stitching the drives together yourself.
Which one sight should I prioritize if I only have a day?
Seongsan Ilchulbong, no contest. The 20-minute climb delivers a crater rim, an ocean view, and Jeju’s most infectious 20 minutes in one cheap ticket, and it pairs naturally with Manjanggul and the Haenyeo Museum on the same east coast loop. Save Hallasan for a trip with a full spare day, the reservation and the 8-10 hour round trip don’t fit alongside anything else.
Confirm current hours and any closures directly with visitjeju.net , the island’s official tourism site, before you lock in a single-day plan around these sights. Our full Jeju travel guide covers the car rental and IDP rules that get you between all of them, and the 2-day through 7-day itineraries slot each sight above into an actual schedule.
