Jeju Island in 5 Days

Fly from Seoul Gimpo to Jeju International Airport; the flight takes roughly an hour. The Gimpo–Jeju corridor is one of the world's busiest domestic air routes, with flights departing as frequently as every 15–20 minutes at peak hours and budget fares available from around ₩30,000 booked several weeks out. Do not confuse Gimpo with Incheon: if you are arriving in Korea on an international flight into Incheon, you need to clear customs, transfer to a domestic terminal, and catch a separate Incheon–Jeju connection. Confirm your terminal before landing. Collect your rental car if you hold an International Driving Permit alongside your home-country licence — rental companies are at the arrivals exit and the lot is five minutes on foot. Without an IDP, download the Kakao T and Naver Map apps before you land; Naver Map is the reliable transit planner on Jeju (Google Maps is inaccurate for Korean public transit and walking routes). After dropping luggage, walk out to Yongduam — Dragon Head Rock — on the north shore, ten minutes by taxi from the airport. The volcanic basalt stack is a modest attraction in itself but places you at the edge of the open Korea Strait immediately, giving a first physical sense of the island's geological character. In the late afternoon, work your way to Dongmun Traditional Market in central Jeju City. The market is liveliest from 5pm: haenyeo divers sell fresh seafood at outdoor stalls, covered rows are stacked with hallabong tangerines and dried fish, and the street food strip at the south end has vendors cooking hotteok and fish-cake skewers. Dinner here — a heuk-dwaeji (Jeju black pork) barbecue at one of the restaurants near the market's edge — sets the culinary tone for the trip. Jeju black pork is raised on the island's volcanic terrain and has a richer, slightly gamier flavour than standard Korean pork; it is eaten grilled, sliced, and wrapped in perilla leaf with fermented paste.

Today is a loop from Jeju City covering the north-central and western parts of the island before you pack for tomorrow's move east. Start with Manjanggul Cave, a UNESCO World Heritage lava tube on the north coast roughly 30 minutes east of the city centre. The accessible section runs about a kilometre into the earth before reaching the world's largest lava column still attached to its floor — a 7.6-metre basalt tower formed when the surrounding lava drained away and left the column behind. Lighting inside the cave is minimal and the temperature drops to around 11°C year-round regardless of outside conditions, so bring a light layer. The cave reopened to visitors in 2026 after maintenance work. From Manjanggul, drive west along the north coast to Hallim Park, a landscaped complex built around two more lava caves — Hyeopjae and Ssangyong — with sub-tropical gardens and Hyeopjae Beach immediately adjacent. The cave experience here is shorter and better lit than Manjanggul, which makes it more accessible for young children or for visitors who found Manjanggul's darkness uncomfortable. The beach itself is worth noting: the turquoise water over white sand on this stretch of the west coast reads as improbably clear for a Korean island, and it is significantly less crowded than the better-known east-coast beaches. Spend the afternoon further south on the west side at the Osulloc Tea Museum. The museum sits at the edge of large terraced tea fields that change character through the year — vivid green in summer, lighter and more textured in spring when new growth appears. The Innisfree Jeju House adjacent to it sells skincare products and a small tea-based menu. The Yongmeori Coast, a short drive south from Osulloc, is a layered sandstone platform eroded by the sea into channels, ridges and overhangs — a 30-minute walk with architectural geometry that feels different from Jeju's more typical basalt scenery. Return to Jeju City for a second night.

Check out of your Jeju City accommodation and drive east to Seongsan — roughly 75 kilometres along the north coast highway, about one hour in light traffic. There is no urgency today because the landmark experience at Seongsan Ilchulbong is more rewarding in low morning or late-afternoon light than at midday, when the coastal light flattens and tour groups fill the summit path. Arrive in Seongsan by noon. Check in, then walk south along the coast road to Seopjikoji, a headland about three kilometres from the Ilchulbong ticketing gate. The trail crosses open fields of wildflowers (particularly striking in spring) to reach a lighthouse perched above a rock-shelf coast. From there, the view back north to the tuff cone is unobstructed and wide-angle — a better vantage for understanding Ilchulbong's geography than the view from its own summit, which looks down into the crater and out to sea but cannot show the cone as a whole. Across the water to the northeast you can see Udo Island on a clear day. Buy your Seongsan Ilchulbong ticket (₩5,000 adults) in the late afternoon. The wide, well-maintained stairway to the 182-metre crater rim takes roughly 20-30 minutes at a moderate pace. The caldera bowl holds a tidal flat that floods and drains with the tide; from the rim you look down into the grassy crater and out over the east cape and the surrounding sea. The site closes on the first Monday of every month, and the ticketing window closes one hour before the official closing time, so check the current seasonal schedule at visitjeju.net before going. Sunrise is the famous time to be here — tomorrow morning.

Set your alarm. Seongsan Ilchulbong earned its name — Sunrise Peak — because the view from the crater rim at dawn is among the most photographed scenes in South Korea: a column of light emerging behind the open sea, with the crater floor and the east cape below. Arrive at the gate 40–50 minutes before official sunrise time; on spring and autumn weekends the path up becomes congested by 6:30am. Tickets from the previous evening remain valid. Descend and have breakfast in the village — most cafes open by 7:30am for the sunrise crowd. Pack up and drive south and west to Seogwipo, approximately 50 kilometres along the south coast road. The direct route takes 50–60 minutes; the inland road through tangerine orchards adds 15 minutes but passes quieter village roads with fruit stalls that sell hallabong and other citrus directly off the tree in season. In Seogwipo, walk the south-coast trail linking the three central natural features before the afternoon light fades. Cheonjiyeon Waterfall is a short path from the city centre through a subtropical gorge thick with tree ferns and subtropical plants; it drops into a pool where the water is calm enough to reflect the surrounding greenery. Jeongbang Waterfall, 1.5 kilometres east along the coast path, falls 23 metres directly onto rock shelves at the sea's edge — Korean tourism authorities describe it as the only waterfall in Asia that falls directly into the sea, a claim that draws some debate but captures what makes it visually distinct. Oedolgae, another kilometre along, is a 20-metre volcanic rock column that rises from the surf offshore and frames cleanly against the cliffs behind. All three are linked by a coastal footpath that takes about 90 minutes to walk end to end, including time to pause at each site. Have dinner in Seogwipo. The city has a concentration of restaurants serving raw fish (hoe), abalone porridge (jeonbok-juk), grilled mackerel, and Korean home cooking at honest prices. The nightly fish market at Seogwipo Maeil Olle Market is worth a look even if you eat elsewhere.

Day 5 divides into two completely different experiences depending on whether you secured a Hallasan summit reservation before leaving home. The two trails that reach the summit crater — Seongpanak (starting on the island's east side, 9.6 km one way) and Gwaneumsa (northeast, 8.7 km one way) — require advance online reservation through visithalla.jeju.go.kr. Slots open on the 1st business day of each month at 9AM Korean Standard Time for the following month and fill within hours during spring and autumn. Reservation is free but requires email verification; carry your original passport on the day as it is checked at the trailhead gate. The round trip to the summit crater lake, Baengnokdam, takes 8–10 hours. If you have a Seongpanak reservation, leave Seogwipo by 6AM to reach the trailhead in time for the mandatory entry cutoff. The summit sits at 1,950 metres and the trail passes through dwarf beech forest, rocky switchbacks, and open crater moorland; it is one of the more physically demanding but rewarding day hikes in Korea. Non-summit trails such as Eorimok and Yeongsil do not require a reservation and deliver strong mountain scenery without the full commitment. Without a reservation, drive west from Seogwipo along the south coast instead. The Jusangjeolli Cliffs, 20 minutes west of the city centre, present a formation of hexagonal basalt columns eroded at the base by the surf. The visual similarity to Giant's Causeway in Ireland is striking; the columns here are set into a curved coastal platform that concentrates the wave action. Continue northwest to Hyeopjae Beach on the west coast — shallow turquoise water over white sand with a clarity that consistently surprises visitors expecting an East Asian sea — and then cut back through Osulloc for a final walk through the tea fields before heading north to Jeju City airport. Both options converge on the north coast in the afternoon. Return the rental car at the airport lot and allow 90 minutes from the south coast to account for refuelling and the return queue during peak periods.

• Jusangjeolli Cliffs and Hyeopjae Beach as the alternative
• The drive back to Jeju City airport
