May brings a visible change to Korean Buddhist spaces. In the weeks around Buddha's Birthday, lanterns appear at temples and festival sites, while UNESCO-listed Yeondeunghoe brings processions, performances and traditional cultural activities into central Seoul. The exact dates follow the lunar calendar and change each year.
The festival provides the starting point rather than the entire subject of the journey. Travellers first encounter Buddhism as a public celebration, then trace older religious heritage in Gyeongju before entering a working temple environment in Busan. The sequence moves from celebration to historical context to participation, so the templestay develops the story rather than feeling like a separate add-on.
