Jeju 6 Day Itinerary (No Tourist Traps)
Six days completes the round-island loop from the 5 day version , then adds a full day on Hallasan itself, South Korea’s highest peak, reservation system and all. This is the version to book if seeing the volcano up close matters as much as the coastline does.
Book these before you go:
- A Jeju City hotel : base here for the first two nights and again after Hallasan
- A Seogwipo hotel : switch bases for the south and west coast days
- A rental car : a physical IDP obtained before you fly is required to drive it legally
- Your Hallasan summit slot at visithalla.jeju.go.kr : book the moment your dates are fixed, this is the single most likely thing on this trip to sell out

Day 1: Jeju City
Land at Jeju International Airport, effectively inside Jeju City itself, and pick up your rental car if you booked one; counters are a short shuttle from arrivals. Drop your bags, then walk Yongduam, the dragon-shaped rock at the harbor. For dinner, head to Heukdwaeji-geori, the black pork street in Geonip-dong: a full block of restaurants grilling Jeju’s native black pig breed, budget roughly 20,000-25,000 KRW per person.
Day 2: The east coast
Drive east about an hour to Manjanggul, the UNESCO-listed lava tube reopened 30 May 2026 after safety repairs; roughly 1km of its 7km-plus length is open to walk, entry runs about 4,000 KRW. Stop at the Haenyeo Museum in Gujwa-eup before continuing to Seongsan Ilchulbong: entry to the crater rim runs about 5,000 KRW, and the coastal path around the base is free if you skip the climb.
Day 3: Udo Island
Take the roughly 15-minute ferry from Seongsan port (about 10,500 KRW round trip) to Udo, a small offshore island worth a full day rather than a rushed half-day add-on. Rent a bike to circle the coastline and try the peanut ice cream, a genuine local specialty. Head south to Seogwipo in the evening.
Day 4: Seogwipo and the south coast
Walk to Cheonjiyeon Falls, then Jeongbang Falls, one of the few waterfalls in Asia that drops straight into the ocean. Drive 20-30 minutes west toward Jungmun for Cheonjeyeon and the Jusangjeolli basalt columns, hexagonal rock formed when Hallasan lava met the sea and cooled fast roughly 500,000 years ago.
Day 5: The west coast
Drive northwest toward Sanbanggulsa, a cave-temple shrine partway up Sanbangsan. Continue to Hyeopjae beach for an afternoon swim at the patrolled section only, then the Aewol cafe strip for sunset. Loop back toward Jeju City in the evening to be positioned for an early Hallasan start.
Day 6: Hallasan
Dedicate the whole day to Hallasan, South Korea’s highest peak at 1,947m. If you booked a summit slot at visithalla.jeju.go.kr for the Seongpanak or Gwaneumsa trail, start at dawn: both run 8.7-9.6km one way with a four-to-five-hour climb, and rangers enforce a strict descent cutoff from the Baengnokdam crater rim regardless of your reservation. If you missed the booking window, or the reservation requirement happens to be suspended on your dates, the Eorimok, Yeongsil, or Donnaeko trails reach high viewpoints without the summit crater and without a reservation, a genuine full day out on their own. Check the live rule at visithalla.jeju.go.kr the morning of, weather closes trails on short notice.
Do you need to book Hallasan weeks ahead?
Ideally, yes. Bookings open at visithalla.jeju.go.kr on the first of each month for that month plus the next, and slots for the Seongpanak and Gwaneumsa summit trails can fill within minutes in spring and autumn. Reserve the moment your dates are fixed; the requirement holds most of the year even though it is periodically suspended for limited windows.
What if the weather kills your Hallasan day?
Build the buffer in before you fly, not after. This route puts Hallasan last for a reason: if fog or rain forces a cancellation, you can trade Day 5 or Day 6 for a repeat visit to a coastal spot rather than losing the volcano entirely. English.knps.or.kr posts current trail and weather closures for the national park.
Crampons or trail spikes are genuinely necessary on Hallasan’s upper slopes in winter, not optional gear, rent or bring them if you are hiking December through February.
