Jeju Olle Trail

Jeju Olle Trail is Jeju’s best-known long-distance walking network, created and maintained by the Jeju Olle Foundation. The official English trail information confirms 27 routes covering 437km, with route pages setting out distances, estimated walking times and difficulty levels. That scale makes it less a single attraction than a practical way to explore the island’s coastline, villages, oreum landscapes and everyday rural scenery at walking pace. For visitors who want to understand Jeju beyond a short scenic stop, it offers a structured, well-signposted framework rather than an improvised hike. It is also a useful choice because the network is actively managed rather than simply mapped once and left alone. The official site publishes notices about route changes and temporary diversions, and it promotes guided, volunteer and conservation-linked programmes through the foundation. The organisation’s office is on Jungjeong-ro in Seogwipo, which helps confirm the on-island operating base behind the trail system. This is therefore a strong island-wide experience rather than a single viewpoint: flexible, geographically broad and closely tied to Jeju’s walking culture, with enough official route detail to let travellers choose anything from a half-day section to a longer multi-route plan.
