Jeju City in 3 Days — 3-Day Guide

Jeju City in 3 days: the island where 3,500 female free-divers dive without equipment to 20m in a UNESCO-recognised tradition, where a volcanic tuff crater rises from the sea like a natural amphitheatre for the sunrise, and where the world's longest lava tube keeps a constant 11°C year-round.

Language	Korean (한국어). Jeju has a somewhat distinct dialect (Jeju-eo — 제주어 — UNESCO-listed as a critically endangered language; unintelligible to mainland Korean speakers; essentially spoken only by elderly islanders above 70). In practice, all residents speak standard Korean (and the younger generation in the tourism industry speaks English at the major sites). Key phrases: 'Haenyeo' (해녀 — female diver), 'Hallasan' (한라산 — the volcano), 'Jeju흑돼지' (제주흑돼지 — Jeju black pig).
Currency	South Korean Won (₩). T-money card works for buses from Jeju Airport into the city and for some island bus routes. Cards accepted everywhere in restaurants, hotels, and at major attractions. Jeju is one of South Korea's most expensive domestic destinations (accommodation is 30–50% more expensive than equivalent mainland cities). Budget ₩100,000–200,000 (€68–136)/day.
Transport	Car rental is essential for Jeju Island — public transport (buses) is infrequent and slow for the major sites. Car rental: ₩40,000–80,000/day (Jeju has 20+ rental agencies at the airport; book in advance for July–August). Driving is on the right. Alternatively: taxi tours (many Jeju taxis offer full-day tour packages, ₩100,000–150,000/day). Airport bus to Jeju City: ₩1,200, 30 min.
Best time	April–May (the canola flower (유채꽃 — yellow rape flower fields covering the eastern Jeju flatlands; 1 million+ visitors in peak canola season (March–April)); the best photography month for the island). September–November (autumn — cooler (18–25°C), the Hallasan summit trail accessible, fewer tourists). December–February: cold (5–10°C) but Hallasan has snow and the volcanic landscape is dramatic. July–August: peak Korean summer holiday crowds, prices 50% higher.
Getting in	Jeju International Airport (CJU): 4km from Jeju City centre; the second-busiest airport in South Korea (25M passengers/year); domestic flights from Seoul Gimpo (50 min, ₩50,000–120,000), Seoul Incheon (60 min), Busan (50 min), and every Korean city; direct international flights from China, Japan, Taiwan. Ferry from Mokpo or Busan (12 hrs overnight ferry — a classic Korean travel experience).
Tipping	No tipping in South Korea. The convention applies on Jeju as everywhere in Korea. The haenyeo performance tips: not expected but if you wish to support the haenyeo community, donate to the official Jeju Haenyeo Preservation Association rather than individual performers.
Safety	Jeju is extremely safe. The island is one of the most tourism-friendly destinations in Asia. The main practical concerns: (1) Hallasan summit trail weather (mist and rain can develop suddenly even in summer — bring rain gear); (2) ocean swimming (the sea around Jeju has currents; swim only at designated beaches with lifeguards); (3) Seongsan Ilchulbong sunrise climb is steep and slippery — wear non-slip shoes.
Budget tips	Seongsan Ilchulbong: ₩2,000. Manjanggul Lava Tube: ₩4,000. Jeju Folk Village: ₩12,000. Haenyeo Museum: ₩1,100. Udo Island ferry: ₩5,900. Hyeopjae Beach: free. Cheonjeyeon Falls: ₩2,500. Black pig BBQ dinner: ₩25,000. Car rental: ₩50,000. Budget ₩100,000–180,000 (€68–122)/day.
