Combate Naval del Río Grijalva

The pyrotechnic centerpiece of Chiapa de Corzo's Fiesta Grande, this nighttime spectacle on the Río Grijalva recreates a historic battle between Spanish colonizers and Indigenous Chiapanecos through choreographed explosions on and above the water. It takes place on the evening of January 21 as part of the broader San Sebastián Mártir celebrations, and is one of the most anticipated single nights of the entire festival.
