San Antonio's Hemisfair grounds and the Arneson River Theater fill with glowing diyas, marigolds and the smell of Indian street food Saturday night as DiwaliSA returns for its 18th edition, running from 4:30 p.m. to midnight with free admission for everyone who shows up.
The celebration is co-hosted by the City of San Antonio and Anuja SA, according to the San Antonio Express-News, which reports the two groups are leading this year's event. Anuja SA, a nonprofit that promotes the sister-city alliance between San Antonio and Chennai, India across fields including art, medicine, education, business and sport, describes DiwaliSA as its signature celebration on its own event page at anujasa.com. The organization spearheaded the Alamo City's Diwali tradition, per the Express-News, and the nonprofit's site confirms this year's festivities run from 4:30 p.m. to midnight at the Arneson River Theater and Hemisfair.
Diwali itself is a Hindu festival of lights symbolizing the spiritual victory of good over evil, the Express-News notes, with the name tracing back to the Sanskrit term dipavali, meaning row of lights. A companion report from KSAT frames that same idea slightly differently, describing the holiday as symbolizing the triumph of light over darkness and good over evil. KSAT also confirms admission to Saturday's event is free.
What's Planned on the Riverwalk
Expect a packed lineup along the water: the Express-News reports the celebration includes Indian food and music, art displays, a river parade and fireworks; an arts event listing also mentions a DJ dance party. Anuja SA's own site adds detail on the main stage program, noting that dancers, musicians and artists share the richness of Indian culture throughout the night, with glowing diyas, marigolds and vibrant rangoli set up across the grounds. A San Antonio arts event listing, per events.getcreativesanantonio.com, similarly describes this year's event as including a river parade along with music and dance performances, and notes the festival traditionally lands on the first Saturday of November every year.
Last year's festival offers a sense of what the river parade and related ceremonies can look like. At the 2025 event, floats representing several states of India moved along the water during the River Parade, according to Texas Public Radio, while attendees gently placed candles that floated on the river during a Diya Ceremony. That same report described an India Bazaar featuring authentic Indian attire, jewelry and art, and noted that thousands gathered at Hemisfair for the occasion, which organizers marked as the festival's 17th year. A separate account from the San Antonio Report similarly described last year's gathering as free and open to the public, with traditional Indian dance, food, crafts and a river parade among the draws.
A Citywide Tradition
Anuja SA president Kausi Subramaniam has invited people to share food and try clothing at the festival. The festival has grown considerably since it began.
DiwaliSA began in 2008, while Anuja SA was founded in 2011. About 15,000 people attend the festival on average. The 2023 edition marked the festival's 15th year, and KSAT reported it ran on the same free, 4:30 p.m.-to-midnight schedule that organizers have kept in place for Saturday's 18th edition.
