Dadaepo Beach sits at the western edge of Busan, where the Nakdong River meets the sea. It is broader, shallower, and usually less famous than Haeundae or Gwangalli, which makes it a good choice if you want a quieter beach stop.
The soft sand and shallow water suit families, and the sunset views are the main reason to time a visit late in the day. In peak summer, check which part of the beach is patrolled before swimming.
