Land at Jeju Airport, collect luggage and buy a T-money or local transport card at the airport convenience store to pay for buses and ferries — this saves time and avoids cash-only situations.
Catch an airport/intercity bus heading east (some services go direct to Seogwipo with stops near Seongsan; if not, change at Jeju Intercity Bus Terminal). Check Naver Map/KakaoMap for up-to-date timetables and platform info.
Eat at a harbour-side café near Seongsan Port — order haemul bibimbap or grilled mackerel for freshly caught island flavours; cafés generally serve lunch until mid-afternoon.
Take a short local bus or taxi to Manjanggul to walk a section of this UNESCO-listed lava tube with fascinating lava formations; visitor centre and the show cave are usually open through the afternoon (approx 09:00–17:30/18:00).
Return by local bus/taxi to Seongsan Ilchulbong and stroll around the rim or the coastal viewing areas — there is no strict closing time but daylight is needed for the trail, so plan before dusk.
Hop on a local bus or short taxi ride to Seopjikoji for dramatic cliff-top coastal views and photo spots; the outdoor site is accessible in daylight and popular in the early evening.
Take an intercity or coastal bus from Seopjikoji/Seongsan back to Seogwipo (some services run along the south coast), check in to your accommodation and freshen up; carry a paper itinerary or app for bus platforms.
Walk the lively market and sample local specialties — try Jeju black pork, grilled seafood and fresh sashimi from stall vendors; many stalls are open into the evening for relaxed eating.
Wander the mural-lined Lee Jung Seop Street near Seogwipo Port with small galleries and cafés — the street is open anytime and is a pleasant low-effort way to end your first day.
Depart early on a scheduled intercity or local bus from Seogwipo to Seongsan Port; buses running this route have early departures but frequencies vary, so check timetables the night before and arrive 30–45 minutes ahead of the ferry.
Take the short ferry crossing to Udo — the island is famed for coastal loops, lighthouses and peanut ice cream; morning ferries are less crowded and depart frequently in high season (check the Seongsan Port notice board).
Rent an e-bike/scooter or join the island loop bus to visit Seobin Baeksa white sand, Udo Lighthouse and scenic headlands — rentals open with ferry arrivals and island buses run on fixed loops, so plan based on your comfort with cycling.
Try Udo’s peanut ice cream plus a simple seafood bowl or haemul pajeon in a harbour café; island cafés typically serve through lunchtime and offer fresh local ingredients.
Catch an early afternoon ferry back to Seongsan Port — check the return timetable in advance so you don’t miss the last crossings during quieter seasons.
From Seongsan, take a local bus or short taxi to Jusangjeolli to admire the spectacular hexagonal basalt columns meeting the sea — the coastal promenade is accessible in daylight (popular until dusk).
Travel by local bus to Cheonjiyeon Waterfall in Seogwipo and enjoy the landscaped path and tranquil pool; the entrance and pathways are usually open during daytime (roughly 08:00–18:00 but check seasonally).
Walk or take a short bus/taxi ride to Jeongbang, one of Asia’s rare waterfalls that drops into the ocean — the site has easy access and is impressive in late afternoon light.
Take a coastal bus or taxi to Oedolgae Rock for wide ocean views and nearby cafés where you can watch the sunset — cafés often operate through early evening but check closing times during off-season.
Finish the day with a seafood feast at a harbour restaurant — consider haemultang (seafood hotpot), fresh sashimi or abalone dishes; many establishments stay open late but confirm last seating times.
Have a relaxed breakfast at a local café or try abalone porridge at a nearby restaurant to fuel a gentler travel day; cafés typically open from 07:00–08:00 onwards.
Catch a public bus toward the Jungmun resort area and alight at Camellia Hill for gardens and a peaceful walk — Camellia Hill usually opens around 09:00 and closes by late afternoon (check seasonal hours).
Stroll the Jungmun coastal area and pop into Innisfree Jeju House or nearby gardens for quick photos and souvenirs; many sites open from 10:00 but opening hours can vary by attraction.
Take an intercity bus north to Jeju City and enjoy a final meal at Dongmun Market — black pork, seafood and street snacks are highlights and the market is lively at lunchtime.
Use city buses to visit Jeju Stone Park for cultural exhibits and walking routes (usually open ~09:00–18:00) or a quick stop at Yongduam for coastal photos — both are good short stops before the airport transfer.
Allow time for souvenir shopping, a café rest or to top up your transport card; build in buffer time for traffic and bus schedules when heading to the airport.
Catch an airport limousine or intercity bus from Jeju City to Jeju Airport (frequent services available); for international flights allow 2–3 hours at the airport, domestic 60–90 minutes.
