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.

Spring Highlights

Cherry Blossom Festival (early April): 2 km of cherry trees in Jeju City center, evening illumination. Stay in Jeju City (Old Hyeon-dong/Tap-dong district) to walk to the main venue.

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

Seopjikoji: East coast volcanic landscape — lighthouse, grassland, blue ocean. Spring’s returning green makes the scenery most layered. Free admission, parking KRW 3,000 (~$2).

Spring tips: Hay fever sufferers beware — April pollen peaks at “High” level. Cherry blossom week hotels surge 50—80%; book 2 months ahead.

Autumn Highlights

Hallasan Autumn Colors (late Oct to mid-Nov): The Eorimok trail (5.8 km, 4 hours) is the most accessible route, no special gear needed. Korea’s most beautiful autumn, bar none.

Sangumburi Crater: Parasitic volcanic crater with autumn reed fields and red foliage — photographer’s paradise. KRW 5,000 (~$3.5) admission, much easier to reach than Hallasan.

Tangerine Picking (Sep—Nov): Jeju’s tangerines (including the famous Hallabong) are in harvest season. Book picking experiences on [Klook]https://www.klook.com
