Dongsam Seawater Stream (also known as Dongsam Sea Stream) is a picturesque waterway located in the Yeongdo district of Busan. It has gained popularity as a 'hidden gem' for cherry blossom viewing, offering a more tranquil alternative to the city's more crowded spots like Oncheoncheon or Samnak Park. The stream is lined with cherry trees that create a stunning pink canopy over the walking paths during the spring season, typically peaking in late March to early April.

The best time to visit is during the cherry blossom season, which usually occurs between the last week of March and the first week of April. According to local reports, the blossoms were in full bloom around April 6th in 2025. Visitors should note that while social media videos often use color grading to enhance the pink hues, the natural scenery remains exceptionally beautiful.
