Jeju Island, South Korea 7 Day Itinerary

Hallasan tops out at 1,947 meters, South Korea’s highest peak by a wide margin, and if you want to stand on its crater rim you need to book a summit slot online before you land, not decide on a whim once you are on the island. That single reservation requirement shapes how this whole week should be sequenced, so plan around it rather than discovering it on day three.

Day 1: Arrival and Seongsan Ilchulbong

You land at Jeju International Airport, a compact single terminal with no need for the invented nicknames some blogs throw around. If you are renting a car, the rental zone sits a five-minute shuttle ride from arrivals, and you will need a physical International Driving Permit from a Geneva or Vienna Convention country plus your home license, digital copies are not accepted at the counter. A taxi into Jeju City runs about 6,000 to 10,000 won and ten to fifteen minutes; heading straight to Seogwipo instead costs closer to 40,000 to 50,000 won and 40 to 60 minutes, so factor that into which end of the island you base yourself.

Check in, then head for Seongsan Ilchulbong, the volcanic tuff cone that earned its spot among the New7Wonders of Nature. Full access to the crater rim costs 5,000 won for adults and the site is open 7am to 7pm; the climb itself is a well-built staircase route taking 30 to 45 minutes round trip. If you would rather skip the fee, the coastal trail around the base is free and leads down to Umugae, a black sand beach with a view back up at the peak that rivals the paid vantage point. For black pork, skip generic tourist-strip barbecue and look for a place doing a proper set menu with multiple cuts, portions and quality vary wildly between restaurants clustered near the peak, so check recent reviews rather than walking into whichever one has the loudest signage.

Day 2: Olle Trail and Hamdeok Beach

The Jeju Olle Trail network circles the entire island in 21 numbered routes, and trying to do more than one short stretch in a morning misses the point of it. Pick the section running toward Hamdeok, a walk past low stone walls and coastal cliffs rather than a strenuous hike, and stop for lunch at whatever small eatery you pass rather than planning a specific restaurant, this is a day for wandering. Hamdeok Beach itself has genuinely clear, shallow water and makes a strong case for an afternoon swim if the weather cooperates, with Mt. Hallasan visible on the horizon on a clear day. For dinner, Jeju abalone, either grilled or in a porridge called jeonbokjuk, is a specialty worth seeking out over another round of black pork.

Day 3: Hallasan

This is the day to build your whole schedule around, because Hallasan’s summit trails require an online reservation, and only the Seongpanak and Gwaneumsa routes actually reach the crater rim at Baengnokdam. Booking opens on the first of each month for the following month, so reserve this slot the moment your dates are fixed, not after you arrive. Cutoff times to reach the mid-mountain shelter are strict and get earlier in winter, arriving mid-morning rather than at dawn is a common way visitors get turned back before the summit. If you did not manage to book a summit slot, the lower sections of the mountain are open without reservation and still deliver serious forest and volcanic scenery, that is a reasonable fallback rather than a consolation prize.

Skip the invented “Mystic Road” detour if your time is tight; it is a real optical illusion where cars appear to roll uphill, mildly diverting for five minutes but not worth rearranging a hiking day around. After the mountain, Seongeup Folk Village, an inland settlement of traditional thatched-roof houses and stone walls rather than a beach, gives useful context on how Jeju families actually lived before the island became a resort economy.

Day 4: Manjanggul Cave and the folk village

Manjanggul is one of the longest lava tube systems in the world, and the roughly one kilometer of publicly accessible tunnel is enough to feel the scale of it without a guide, the cave stays a cool 11 to 12 degrees year round so bring a layer even in summer. Afterward, Jeju Folk Village near Pyoseon reconstructs traditional village life across the island’s three historical regions, worth two unhurried hours if you skipped Seongeup the day before. For dinner, look for a place doing Jeju-style tteokbokki, which leans spicier and often includes seafood compared to the mainland version, a distinction worth noticing rather than assuming it is the same dish everywhere in Korea.

Day 5: Cheonjiyeon Falls

Cheonjiyeon, one of Jeju’s three signature waterfalls, drops through a wooded gorge near Seogwipo and is best visited in the late afternoon when the light hits the pool below. Pair it with a slower afternoon rather than cramming in another major sight, a teddy bear museum or similar novelty stop is fine filler if traveling with kids but genuinely optional for anyone else, and I would trade it for extra time at the falls or a walk along the Seogwipo coastal path instead. Dinner near the falls area typically means another round of black pork ribs, by now you will have a strong opinion on which style you prefer, grilled tabletop or braised.

Day 6: The west coast

Yongduam Rock, the “Dragon Head Rock” formation near Jeju City, is a five-minute photo stop rather than a destination, worth seeing if you are already passing through but not worth rerouting your day for. Better to spend the bulk of day six at Cheonjeyeon Falls near Jungmun, a three-tiered waterfall with a striking arched bridge overhead, the Seonimgyo Bridge, decorated with carvings of the seven nymphs the site is named for. The surrounding walking paths through subtropical forest are shaded and pleasant even at midday. Round out the evening with Jeju abalone hot pot, a heartier, more warming version of the dish than the grilled version you likely had earlier in the week.

Day 7: Departure

Use the morning for souvenir shopping, Jeju tangerine products, hallabong citrus liqueur, and green tea from the island’s Osulloc plantations all travel well and are genuinely distinct from what you would find on the mainland. Head back to Jeju International Airport with real buffer time if you are returning a rental car, drop-off queues at the airport rental zone back up badly in the last hour before departure.

Practical notes

Rental cars run roughly 45,000 to 150,000 won a day depending on vehicle class and season, and an international driving permit is mandatory, permits issued in China or Indonesia are specifically not accepted by Korean rental agencies regardless of what the counter staff initially tell you. Public buses cover the island reasonably well but run infrequently outside Jeju City, a car genuinely opens up far more of the island in a week than buses will. Book any Hallasan summit slot the day reservations open for your travel month, they fill fast around weekends and Korean holidays. Weather changes quickly on the coast even when the interior is clear, check conditions for both Seongsan and Hallasan the morning of your visit rather than trusting a forecast from days earlier.
