Haeundae is a 1.5km stretch of sand on Busan's east coast, and it's been Korea's most-visited summer beach for as long as anyone can remember. Even the name has swagger — legend says Choi Chi-won, a Unified Silla-era scholar, personally carved the characters 'Haeundae' into the cliffs of nearby Dongbaekseom. Official swimming season only runs late June through late August, but honestly, Haeundae is worth a trip year-round.
If you're arriving in daylight, start by walking west to Dongbaekseom. It's a small island now joined to the mainland, with a solid coastal boardwalk that takes you past Nurimaru APEC House and a lighthouse — all free — and delivers a front-on view of Gwangan Bridge. Head east instead and you'll find the Sky Capsule (2.3km, roughly 20 minutes, a leisurely 4km/h) and Beach Train running along old rail tracks from Mipo to Cheongsapo. It's popular enough that walk-up tickets can sell out, so book online ahead of time. Keep walking and you'll hit the Cheongsapo Daritdol Skywalk, a suspension bridge over the water that's a legit rush to cross.
The real magic happens after dark. At night, the lights of Marine City and Gwangan Bridge reflect off the water so vividly that just strolling the beach feels like a photoshoot. Get hungry and head into Haeundae Market for street food like eomuk and hotteok, then swing by Haeridan-gil (the alley between the station and the market) for bars and cafes with front-row night views. Grabbing a plate of raw fish at one of the beachfront restaurants or tent bars is basically mandatory.
To get there, Haeundae Station (Busan Metro Line 2) Exits 3 and 5 drop you closest to the sand, while Exit 4 is better if you're headed to the market or Haeridan-gil. ⚠️ There are barely any trash cans along the beach path, so hold onto your rubbish until you reach the plaza or restroom bins. Free bike rentals (1–2 hours, just show ID) are available too, and since Google Maps doesn't really work in Korea, download KakaoMap or Naver Map before you land. For fewer crowds, aim for July through October — though June and July bring monsoon rain, so pack an umbrella.
