The verdict for April
Spring in full bloom
+Mild temperatures and beautiful spring scenery
–Higher demand during blossom season
April brings mild weather and Seoul’s famous cherry blossom season, making it one of the city’s most popular months.
Beautiful and completely full
+Cherry blossom in the first week is worth seeing once.
–The busiest and most expensive stretch of spring.
