Seoul
Karaoke bar or K-pop agencies? Food alleys or fashionable haunts? The only decision to make here is where to go first. With its sun-up-till-sun-down shopping streets, thumping nightlife, and UNESCO-stamped shrines and palaces, the city is a playground cranked up to a maximum. Should you find yourself getting overwhelmed with excitement or the soju flows a little too freely, slip away for a stroll through the verdant Seoul Forest.
