Jeju Countryside in February

April through May and September through November give you the countryside at its best. Spring brings cherry blossoms to the mountain villages and comfortable temperatures around 18°C. The fields turn bright green, and you can hike without sweating through your shirt. Fall is even better — the leaves change color on Hallasan, and the harvest season means the freshest ingredients in countryside restaurants. November can be perfect, with clear skies and temperatures around 15°C. Summer gets humid and crowded with domestic tourists, while winter brings cold winds and closes some mountain trails. But here's a secret — January and February offer the clearest views of Hallasan's peak, and you'll have most hiking trails completely to yourself.
