Today’s St. Patrick’s Day event Highlights in San Antonio

If you’re looking for the most authentic experience in town, head over to The Cottage Irish Pub.

It’s the perfect spot to soak up traditional vibes and enjoy a pint with fellow revelers in a neighborly setting.

For those who want a local twist on the holiday, Los Barrios Family of Restaurants is serving up their signature “Shamrock-Rita” at Los Barrios, La Hacienda, and Viola’s Ventanas. This bright green margarita is a San Antonio staple for the holiday. If you’re craving something sweet after, stop by Krispy Kreme; just wear green when you walk in, and they’ll hand you a free O’riginal Glazed doughnut!

What to Expect Today – Tuesday, March 17, 2026, in San Antonio

Expect heavy pedestrian traffic along the River Walk and near the Alamo today as tourists and locals celebrate. While most major parade road closures occurred over the weekend, street parking downtown will be extremely difficult to find; your best bet is to use the city-owned St. Mary’s Street Garage or the Market Street Garage. If you’re heading to the River Walk, arrive before 11:00 AM to secure a spot at popular patios before the lunch rush begins.
