You step onto a shelf of black basalt above the sea. The trail bends inland and drops you onto a dirt track between rows of tangerine trees. Half an hour later you are crossing a breakwater at a fishing village, watching someone sort dried seaweed in the morning light.
That constant change of scene is the defining quality of the 제주 올레길 (Jeju Olle Trail), and the reason a single course can hold your attention for six hours.
The Woman Who Walked the Camino and Came Home
The trail exists because of one person's walk in a different country.
In 2006, Suh Myung-sook — a Seoul journalist who had spent more than twenty years in the news business, and a native of Jeju — walked the Camino de Santiago in Spain. She came home convinced her own island deserved something equivalent, and in 2007 she founded the Jeju Olle Foundation and opened Course 1.
The name came from the island's own dialect. 올레 (olle) means the narrow lane running from a house gate out to the road — the small private path that connects a home to everywhere else. A whole trail system built on that word is a specific kind of claim about what walking is for.
It took fifteen years to finish. The twenty-seventh and final course, 18-2, opened in 2022, completing a 437-kilometre ring around the island.
Suh Myung-sook died on 7 April 2026. In July she was posthumously awarded the Order of Civil Merit, Moran Medal, for what the trail did to walking culture in Korea. Walking any part of the Olle now carries that history with it, which is worth knowing before you set off rather than after.
Which Course Should You Walk First?
Twenty-seven courses is a paralysing number. In practice, first-timers converge on three of them, and none demands hiking experience.
| Course | Route | Rough distance | Character |
|---|---|---|---|
| 1 | Siheung Elementary School → Gwangchigi Beach | ~15 km, 5–6 hrs | Flat and coastal; finishes beneath Seongsan Ilchulbong |
| 6 | Soesokkak → Jeju Olle Tourist Center | ~11 km, 4 hrs | Estuary, then straight through Seogwipo |
| 7 | Oedolgae → Wolpyeong | ~17 km, 5–6 hrs | Cliff-edge path above the sea |
| 12 | Muleung → Yongsu | ~17 km, 5–6 hrs | West coast, climbs Suwolbong |
| 3-A | Onpyeong → Pyoseon, inland | ~20 km, 6–7 hrs | The hardest of the popular routes |
Treat those times as a walking pace with stops, not a race. Add an hour if you photograph everything, and add another if you break for a real lunch.
Course 1 is the trail's front door. It begins at a village primary school and works its way east along black volcanic shoreline, finishing at Gwangchigi Beach directly under 성산일출봉 (Seongsan Ilchulbong), the tuff crater that rises out of the eastern sea. Note the direction — the famous view is your reward at the end, not your starting photograph.
Course 7 is the one veteran walkers name when asked for the most beautiful stretch. Its centrepiece is 외돌개 (Oedolgae), a twenty-metre basalt column standing alone in the water off Seogwipo, left behind when the softer rock around it eroded away.
The path runs along the cliff above. On a calm day you can hear each wave land at the base of it.
Course 6 connects into Course 7, which makes the pair an obvious two-day trip. It starts at 쇠소깍 (Soesokkak, literally "cow pool end"), a gorge where a freshwater stream meets the sea and the water turns an implausible blue-green.
Because the route ends in central Seogwipo beside the Olle Market, it is the easiest course to break for a proper lunch.
The useful selection rule is this: pick by terrain before you look at distance. Fifteen flat coastal kilometres and twelve kilometres through the 중산간 (jungsangan, Jeju's rolling mid-altitude belt) are not the same day, and the shorter one is harder.
Why 27 Courses Only Go Up to Number 21
This confuses almost everyone at first. The courses are numbered 1 to 21, and yet there are 27 of them.
The extras are sub-courses, marked with a hyphen: 1-1, 7-1, 10-1, 14-1, 18-1, and 18-2. They are full courses in their own right, not shortcuts or variants of the numbered route they sit beside.
Three of them are not on Jeju at all. Course 1-1 is on Udo, the small island off the eastern tip. Courses 18-1 and 18-2 are on Chujado, an archipelago roughly an hour and a half north by ferry.
All three need a boat, a timetable, and in the case of Chujado most likely an overnight stay. Worth knowing before you casually pencil one into a day plan.
How the Trail Keeps You From Getting Lost
There is no admission fee. The path is open to anyone who turns up.
Navigation is built into the landscape. Small horse-shaped markers called 간세 (ganse) are posted along every course, each one facing the direction of travel. Each carries two arrows — blue for forward, orange for backward — so you can walk any course in either direction without losing the thread.
Once you have the ganse in your eye, you stop checking your phone. That is the point of them.
If you prefer a screen, the official Ollepass app is free on iOS and Android and carries offline GPS tracks for all 27 courses. It works on stretches of coast where mobile data does not, and it gives an audio alert as you approach a stamp point.
The Passport, and Whether You Need One
The trail runs a stamp passport, and it is a more serious object than it sounds.
For 20,000 won you get a passport-sized booklet with stamping pages for all 27 routes. Every course has three stations — start, midpoint, and finish — and every stamp is a different design tied to that route. Walk the full 437 kilometres and you receive a completion certificate and a medal.
Buy it at Jeju International Airport, at the Jeju Olle Tourist Center in Seogwipo, or at the Ganse Lounge in Jeju City — worth knowing, since most people land in Jeju City and the Seogwipo centre is an hour away.
It also functions as a discount card at registered businesses along the route, which quietly offsets a good part of the price if you are walking several days.
If a full circuit is not your ambition, skip it. The ganse work exactly as well without a booklet in your pocket.
The Logistics Nobody Warns You About
Most courses run point to point. The trailhead and the finish are in different places, sometimes a long way apart, and this is the single most common way a good day goes wrong.
Before you set off, look up the bus from your endpoint back to where you are staying. Rural gaps run 30 minutes to an hour, and the last useful service can be earlier than you would expect.
Naver Map and Kakao Map both carry live Jeju bus times and both work in English. Build the walk around the bus rather than the other way around.
When to Walk
Autumn is the season, and regulars will say so without hesitation. From September through November the 억새 (eoksae, Korean silver grass) takes over the hillsides, temperatures settle into the range you want for six hours on your feet, and the light softens out of summer's glare.
Walk on a weekday in autumn and you will have long stretches to yourself. Weekends fill up, especially on the photogenic courses near Seongsan.
Spring, March through May, is the close second. Late March and April put yellow canola across the island, which is a colour the coastal walk does not otherwise get.
Summer is possible with planning. Coastal sections have almost no shade and Jeju humidity in July and August is substantial. Starting before 8 a.m. and finishing by early afternoon is not a tip, it is the requirement.
Rain changes the maths on cliff sections and oreum ridges. Wet basalt is unpredictably slick, and wind on an exposed cliff path in a squall is a different proposition entirely. The official guidance is to postpone exposed coastal and summit sections when rain is forecast.
What to Actually Carry
The Olle is not an expedition, and overpacking is the more common mistake. A few things earn their place.
Trail runners over boots on the coastal courses. Most of the surface is basalt, packed dirt, and village road. Heavy boots buy you nothing and cost you comfort by hour four.
A windproof layer, always. Jeju's coast is exposed and the wind runs year-round. A day that starts mild can turn genuinely cold on an open headland, and the temperature you feel on a cliff is not the temperature on your phone.
More water than seems necessary. Convenience stores appear in villages, but coastal stretches can run two hours with nothing on them. Sun protection matters for the same reason — there is very little shade on the shoreline sections.
Cash in small notes. Village shops, roadside tangerine stands, and the occasional harbour restaurant do not all take cards, and the ones that do sometimes do not take foreign ones.
Leave the trekking poles unless you are doing an inland course. On flat basalt they mostly get in the way.
Walking Alone
Some coastal sections run through genuinely remote terrain for an hour or more at a stretch. That is part of the appeal and also a thing to plan around.
The Jeju Olle call centre (064-762-2190) asks solo walkers to contact them before setting out. It costs nothing and takes a minute.
The organisation also lends smartwatches to solo walkers free of charge, against a refundable 50,000 won deposit, providing GPS tracking and an emergency contact function. Women walking alone are the group this service was built for, and it is used.
What It Feels Like Underfoot
There is a specific sensation to walking on old lava. Jeju basalt is rough in a way that grips — your sole holds it differently than it holds gravel or packed earth. On a dry day the rock feels almost cooperative. In rain it does not.
The shape of an Olle day is much the same whichever course you pick. The first hour is administrative: finding the trailhead, getting the ganse into your eye, settling a pace. The middle hours are when the island actually opens. By the final stamp your legs have the kind of tiredness that reads as earned rather than spent.
What people who have done both tend to say is that the Olle is quieter inside the head than the Camino. The Camino has albergues, pilgrim culture, a social density that becomes the journey.
Jeju Olle on a Tuesday in October can go an hour without another walker in sight — just the sea below and the next ganse pointing round the bend.
Which may be exactly what Suh Myung-sook was after when she came back from Spain and started measuring her own coastline.
