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

If you missed the weekend parades, you can still catch the spirit at Mad Dogs British Pub on the River Walk. They are hosting a recurring St. Patrick’s Day Parade & After Party throughout the day. It’s the perfect spot to grab a fish and chips basket and watch the festivities right from the river level. Arrive early if you want a seat near the water, as the River Walk is expected to be busy with holiday crowds.

For those looking to keep the party going into the evening, the San Antonio Official St. Patrick’s Day Bar Crawl kicks off at 5:00 PM, starting at the Hard Rock Cafe. This is the definitive way to explore downtown’s best Irish-themed stops with a group of fellow revelers. Since this is a Tuesday, expect a high-energy “after-work” vibe, and be sure to have your digital tickets ready for a smooth check-in at the Hard Rock.

The iconic St. Patrick’s Green River remains a must-see today. While the main dyeing happened over the weekend, the eco-friendly emerald tint typically lingers, making for the best photo ops in the city. Take a stroll near the Arneson River Theatre for the most vibrant views. Pro tip: Wear comfortable walking shoes, as parking downtown will be tight, and you’ll likely want to explore the full loop of the downtown reach to see the green water against the historic architecture.

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 street closures from the weekend have reopened, expect delays near the Hard Rock Cafe and La Villita during the evening hours. For the easiest experience, utilize the city’s St. Mary’s Street Parking Garage or the City Tower Garage to avoid the premium event pricing at smaller private lots.
