Today’s Halloween Day event Highlights in San Antonio

Kick off the festivities early on the Southside at Traders Village — 2026 Trick R Treat Trail, where little ghosts and ghouls can weave through candy stations and pumpkin decorating before tackling the massive 10-acre corn maze. If you prefer your marine life with a seasonal twist, head downtown for Trick or Treat Under the SEA — SEA LIFE San Antonio to watch scuba divers carve jack-o’-lanterns alongside sharks and stingrays.

Younger candy hunters looking to get active will love the high-energy dance floor, glowing bubble foam, and sweet stops at Trick-or-Treat at The DoSeum, while those craving an easy afternoon air-conditioned stop can grab sweet treats and character selfies at Ingram Park Mall — Mall-O-Ween Trick-or-Treating.

When the sun sets, San Antonio’s nightlife turns wickedly thrilling. Older teens and brave adults can venture into cinematic terrors at Six Flags Fright Fest or brave the historic corridors of the Restful Sleep Hotel at HallowFright Weekends at The Scream Experiment right on Alamo Plaza.

If your spooky style favors craft cocktails and socializing over jump scares, don your wildest outfit and join the crowd making its way through downtown watering holes for the San Antonio Halloween Bar Crawl (Crawl With US). Wrap up your evening with community contests at Hall-O-Fest at Chicken N Pickle—and do not forget to cash in on free treats in costume today at Krispy Kreme Free Doughnut in Costume or grab discounted dinner with Chipotle Boorito.

What to Expect Today – Saturday, October 31, 2026 in San Antonio

Heavy traffic is anticipated throughout the late afternoon along Loop 410, I-10 near La Cantera, and the Alamo Plaza corridor as families head out for early trick-or-treating and bar crawls commence. If you are heading downtown or toward major attractions like Six Flags Fiesta Texas, plan to arrive at least 30 to 45 minutes ahead of schedule and utilize pre-paid parking garages around Commerce and Houston Street to avoid congestion.

Neighborhood streets in areas like Stone Oak, Alamo Ranch, and Southtown will see dense pedestrian foot traffic starting around dusk, so drive with extra caution.
