San Antonio is the ultimate day trip from Austin—missions, museums, and mesquite‑smoked BBQ in one loop. Pick up your car rental in Austin and point south on I‑35; downtown San Antonio is about 80 miles away. Here’s a realistic one‑day plan with easy parking and time for the River Walk.
Morning: The San Antonio Missions
Start at Mission San José (the visitor center) to learn the story of the mission system, then continue to Concepción and San Juan. They’re active parishes, so be respectful of services and photography rules. Parking at each site is free and straightforward; restrooms and shaded areas make quick stops comfortable.
Midday: BBQ or Historic Market Square
Craving Texas barbecue? Aim for an early or late lunch to dodge lines and secure a shady table. Prefer a stroll? Market Square blends food halls, folk art, and mariachi music just a short drive from downtown.
Afternoon: The Alamo & River Walk
The Alamo’s plaza sits a few blocks above the River Walk, so you can park once and do both. Take a slow loop along the water, browse shops, and consider a boat tour at golden hour. Families might add a quick visit to the Briscoe Western Art Museum or the Pearl District for dinner.
Parking Made Easy
Use city garages near Houston Street or Commerce Street for central access to the River Walk. Rates are typically posted at the entrance; bring a card, and photograph your level to find the car quickly later.
