National Chaya Festival in La Rioja
A February harvest celebration rooted in Diaguita Pachamama rituals, where locals douse each other with flour, water and wine and pin basil sprigs to each other as blessings. Staged encounters called topamientos, open-air penas and a folk-music program fill La Rioja province for several days, blending pre-Hispanic tradition with Carnival-season festivity.
Basil sprigs, flour and thrown water are the calling cards of La Rioja's chaya, a February rite that predates the city's Spanish foundation.
