About Busan
Busan is South Korea’s laid-back coastal powerhouse—equal parts beach city, seafood capital, and gateway to scenic hikes and temples. Start around Haeundae for wide sands, sunrise walks, and a skyline that glows at night, then head to Gwangalli for waterfront cafés and views of Gwangan Bridge. Explore the old-school energy of Nampo-dong, snack your way through BIFF Square, and dive into fresh sashimi at Jagalchi Fish Market. For a splash of color, wander the hills of Gamcheon Culture Village, and for a coastal wow-moment, visit Haedong Yonggungsa, a sea-cliff temple that feels made for golden hour. Wrap it up with ocean views at Taejongdae or a breezy ride along Songdo’s coast.
