Fiestas de la Calle San Sebastián (SanSe)

SanSe is Puerto Rico's biggest street festival, transforming Old San Juan's historic Calle San Sebastián into a four-day, four-night celebration of Puerto Rican music, food, and art. Live salsa and reggaeton acts play on multiple stages, artisan vendors line the cobblestone streets, and the festival typically runs Thursday through Sunday of the third weekend of January.
