Seoul is the heart of the country. It's the capital city and is home to about half of the entire population of Korea. The Han River winds through its center, offering areas for recreation from biking to boating. It features a world class public transportation system, making it possible to get anywhere in town quickly, cheaply, and reliably via subway, bus, or taxi. Its numerous neighborhoods include world-famous Gangnam, Westerner-filled Itaewon, and young-and-trendy Hongdae. With no shortage of restaurants, historical sites, entertainment, or people to meet, Seoul is a true global city.
