Key ideas in Exploring Jeju Island
- The Jeju Olle Trail is marked primarily with distinctive blue and orange ribbons tied to trees, fences, and poles
- Signage also includes blue pony statues or directional arrows (Ganse) pointing the trail route
- The wayfinding system is designed to allow continuous navigation along Jeju's coast without digital devices or GPS
- Jeju is dotted with over 360 oreums—small secondary volcanic cones—that usually require only a 20- to 45-minute walk to reach the rim
- Oreums offer open vantage points across Jeju's coastal plains and surrounding ocean without demanding extensive hiking gear
- Mount Hallasan occupies the center of the island and reaching its summit requires a strenuous 7- to 9-hour round trip
- Mount Hallasan stands nearly 2,000 meters high in the center of Jeju, acting as a massive meteorological barrier
- The northern side (Jeju City) regularly experiences cold winds and overcast skies while the southern side (Seogwipo) enjoys milder, sunny microclimates
- A 40-minute drive across the island's central spine often shifts the weather completely
- Jeju's local all-stop buses loop around the perimeter coastlines and take a very long time to circle around
- Direct north-south transit across the interior relies on express buses (color-coded red) running along arterial highways like the Pyeonghwa-ro or 516 Road
- Rental cars provide the flexibility needed to traverse central Jeju without detouring through coastal hub connections
- Jeju's haenyeo harvest seafood through free-diving without oxygen equipment or scuba tanks
- Haenyeo operate in democratic, female-led diving collectives that manage communal grounds and protect against overfishing
- Dol hareubang are carved from Jeju's porous volcanic basalt with distinctive bulging eyes and round hats
- Historically, they were placed at fortress entrances and administrative borders as protective guardians rather than simple modern garden ornaments
