Jeju Island — South Korea’s most popular vacation island, just 1 hour from Shanghai by air. But “spring or autumn?” trips up many planners. Both seasons offer unique natural beauty and their own pitfalls. This guide uses data to help you choose.
One-line answer: Autumn saves $90/person on a 4-day trip and delivers richer scenery. Spring wins only if cherry blossoms are your must-see.
Bottom Line
- Best photos and natural scenery: Autumn (late September to mid-November)
- Easiest itinerary and seafood: Spring (late March to early May)
- Budget-conscious: Autumn — flights and hotels run 15—20% cheaper
- Family trips: Spring — more stable temperatures, lower pollen

Spring: Cherry blossom season lasts only 7—10 days around early-to-mid April. Miss it and you wait a year. May brings hydrangeas and rapeseed flowers.
Autumn: Swimming is still possible in September (sea temp 22°C+). October brings gradual foliage, peaking in mid-November. Hallasan Mountain (Jeju’s highest peak, 1,950m) offers Korea’s most spectacular autumn colors.

Seogwipo Olle Market: Jeju’s largest traditional market. Spring brings the freshest abalone, sea urchin, and Jeju tangerines.
