437km volcanic islands circuit. (Across 1 large & 3 smaller islands) Ferry rides between islands.
Collect stamps in your Jeju Olle passport as you amble along.
Plenty of food, water & accommodation along the way, so travel light. You can also camp.
Side trips...watch traditional women divers (Haenyeo) gathering seafood from the bays, lava tubes, endless supply of parasitic cones, climb the highest peak Mt Halladan @ 1947m, explore the smaller outer islands, scuba diving.
The trail is marked on the Kakao & Naver map apps or download to your own fav map app.
I like the look of this one.
