Travel Essentials
ICN: KST · HKG: HKT
When it's 6:00 PM in Seoul, it's 5:00 PM in Hong Kong.
South Korean passport holders enter Hong Kong visa-free for up to 90 days. No fee, no advance application. Passport must be valid for at least 1 month beyond the date of entry (6 months is safer to avoid airline pushback at check-in). No return ticket is formally required, but immigration may ask about onward plans.
At Hong Kong International Airport (HKG), use the e-Channel automated gates if registered on a previous visit, or go through the standard counter. Processing is fast either way. The 90-day period covers Hong Kong only. Entering mainland China or Macau requires separate authorization. Extensions can be requested at the Immigration Department in Wan Chai before expiry.
Direct flights from Seoul Incheon to Hong Kong run about 4 hours on Korean Air, Asiana, Cathay Pacific, HK Express, and several Korean budget carriers (Jin Air, T'way, Jeju Air). Multiple daily frequencies. Hong Kong uses the Hong Kong dollar (HKD), pegged at 7.75 to 7.85 HKD per $1 (roughly 170 KRW per HKD). Octopus cards work on the MTR, buses, ferries, 7-Eleven, and most restaurants. Buy one at the airport for HKD 150 including HKD 100 stored value. No mandatory vaccinations. The Airport Express to Hong Kong Station takes 24 minutes for HKD 115, or take the A21/A11 buses for HKD 33 to HKD 40.
AREX (Airport Railroad Express) runs two services from Seoul Station: the Direct Train (43 min, ₩11,000, reserved seats) and the All-Stop train (66 min, ₩4,550, unreserved). Both trains serve T1 first, then T2; confirm which terminal your airline uses before boarding.Limousine buses depart from major Seoul neighborhoods and hotels (₩16,000–18,000, 60–90 min depending on traffic). KAL and LIMOUSINE services are reliable. Taxis from central Seoul cost ₩65,000–80,000 and take 60–90 minutes. Deluxe (black) taxis are pricier but English-speaking drivers are more common.
Airport Express runs to Hong Kong Station (Central) in 24 minutes for HK$115, departing every 10 minutes from 5:54am to 1:02am. Octopus card discounts apply. Passengers can check bags in at the airport and retrieve them at Hong Kong or Kowloon Station.Taxis to Kowloon cost HK$250–350; to Hong Kong Island, HK$350–450. Ferry services connect to Macau (1 hr, HK$175–220) and Guangzhou/Shenzhen. The Ferry Terminal is in the airport building; no need to leave the terminal. Buses are slower but serve districts not near the MTR.
Subtropical monsoon climate. Typhoon season (June–October) is the primary disruption risk. The airport operates a T1/T3/T8 signal system and closes for Category T8 or above. Typhoons can arrive with 24–48 hours warning and typically pass in 12–24 hours. Check signals before departure during this window.
Winters are mild and mostly dry (12–20°C), ideal for flying. Spring brings fog and low cloud (March–April) that reduces runway visibility. Summer heat and humidity (30–34°C) are moderated at the airport by its coastal location on Lantau Island.
