Seoul flights every 10-15 minutes. Budget carriers from 30,000 KRW if booked early
Jeju has a special visa-free policy: citizens of most countries can enter Jeju for up to 30 days without a Korean visa, even if they need one for mainland Korea. You must fly directly to Jeju (CJU), not transit through Seoul. Bring proof of accommodation and return flight. This makes Jeju uniquely accessible.
Jeju is 73 km across — a car is ideal. Rental from 30,000-50,000 KRW/day at the airport. International Driving Permit required. Alternatively, the 'Jeju City Tour Bus' (12,000 KRW all-day pass) covers eastern or western routes with English audio. Regular buses exist but are slow and infrequent to remote sites.
Seoul-Jeju is one of the world's busiest air routes with flights every 10-15 minutes. Budget carriers (Jeju Air, T'way, Jin Air) offer fares from 30,000-80,000 KRW one-way if booked 2-4 weeks ahead. Flight time is just 1 hour 10 minutes from Gimpo Airport. No ferries are practical for tourists (13+ hours).
Being an island tourist destination, accommodation and dining cost 20-40% more than Seoul. Budget guesthouses from 40,000-60,000 KRW/night; mid-range hotels 80,000-150,000 KRW. Restaurants average 10,000-15,000 KRW per meal. Save by shopping at E-Mart or visiting local markets for seafood (Dongmun Market in Jeju City).
The dol hareubang (stone grandfather statues) are Jeju's iconic guardians — found at every tourist site. Touching the nose is said to bring fertility. The island's matriarchal haenyeo tradition shaped a culture where women historically led economically. Respect when photographing haenyeo — always ask first.
The summit can go from sunshine to zero-visibility fog in minutes. Check weather at Hallasan National Park website before departing. Trails close for wind speeds over 14m/s. Bring layers, rain gear, and sufficient water (no shops on trails). In winter, ice crampons are mandatory — available for rent at trailheads (~5,000 KRW).
