What is the best month to visit Seoul?
Aim for late September to early November or April to May, when skies are clear and temperatures sit around 15-22°C. Mid-October brings peak autumn foliage at Namsan and Bukhansan, while early April delivers cherry blossoms along Yeouido's Yunjung-ro. Avoid the humid July monsoon.
How do you get from Incheon Airport to central Seoul?
The AREX express train reaches Seoul Station in 43 minutes for ₩11,000, while the cheaper all-stop AREX (₩4,750) takes about 60 minutes. Airport limousine buses run to most hotel districts for ₩17,000, and a taxi costs roughly ₩60,000-70,000 and takes an hour.
Is a T-money card worth buying for Seoul?
Yes. A T-money card (₩4,000 for the card, then top up) works on every subway line, city bus and even taxis, with base subway fares of ₩1,400. Buy it at any convenience store or station machine; it saves time and gives small transfer discounts across the network.
