Here's an excerpt from Visit Korea's site on the trail:
For the global traveler looking for a unique destination, the olle walking paths on Jeju Island are highly appealing. These are 200km of connecting paths that will take travelers all along the south coast of Jeju Island. The Jeju Olle, which were inspired by the famous Pilgrim’s Trail in Spain, was made from the hidden, forgotten routes of Jeju Island, which cars cannot access.The route will take you to forests, mountains, beaches, and remote places and offer unrivalled views over Jeju’s unique, dramatic, volcanic landscape.

I stayed in Seogwipo this time so it was less city like and more nature like and one of the Olle trail is right along the coast outside of the hotel I stayed. I didn't have proper gears on and I brought my parents along so I didn't really went on a long path. Just as far as I can go. I can't remember exactly but I think I was at route 10 since we're close to the Sanbangsan mountain.

The path is not like brick roads laid out for you but they're still accessible. You'll encounter having to go through rock paths, climb uphill or downhill. Like jungle trekking minus the mosquito. At that time, the wind was blowing nicely giving me enough comfort to walk for quite a distance. I encountered beaches with abandoned ships, rock cliffs and a view of another beach that is so breathtaking.
