Bolas de Fuego de Nejapa in Nejapa
Every August 31, Nejapa hosts Bolas de Fuego, a fireball-throwing tradition in which teams of young men in protective gear hurl gasoline-soaked rag balls at each other through the streets. Locally called La Recuerda, it commemorates historic volcanic eruptions and has run for over a century, distinct from the town's September Catholic patronal feast.
On the last night of August each year, the streets of Nejapa fill with fire.
