San Antonio itinerary: 1, 2 and 3 days

San Antonio's main sights sit in a compact downtown loop, so the number of days you need depends less on the city than on how far out you want to go. One day is enough for the Alamo and the River Walk on foot. Two days adds the Spanish missions and Pearl. Three days is the point where a car or a tour starts to pay off.

Start at the Alamo when it opens. Entry to the grounds is free, but the church requires a timed ticket, so book the first slot you can and you will be through before the crowds build. From there, walk south along the River Walk to the bend at La Villita, then continue to the San Antonio Museum of Art or the Pearl if you have the legs.

Lunch on the River Walk or at Market Square, where the Mexican food is cheaper and the portions are larger. In the afternoon, ride a river barge for the standard loop, then walk the Museum Reach stretch north of downtown, which is quieter than the main bend. Finish with dinner on the River Walk or in Southtown.

Day one follows the one-day plan. Day two heads south to the San Antonio Missions National Historical Park. Mission San José is the largest and the one to prioritise; Mission Concepción has the best-preserved painted interior. Both are free to enter. A VIA bus or a short drive connects them, and the whole chain can take half a day.

Spend the afternoon at the Pearl, a former brewery turned food and market district, or at the San Antonio Museum of Art. If you are travelling with children, swap one of these for the DoSeum or the Witte Museum. Keep the evening free for a Spurs game if the schedule lines up (check fixtures).

The third day is for going beyond the city. Northwest of town, the Hill Country towns of Boerne, Fredericksburg and New Braunfels are each about an hour's drive away, with German-Texas food, wineries and swimming holes. Natural Bridge Caverns is closer and works well with children. Both need a car or a booked tour.

If you would rather stay in the city, use day three for a theme park — Six Flags Fiesta Texas or SeaWorld San Antonio — or for a slower pass through the museums. A third day also gives you room to move the missions to a cooler morning if the heat is punishing.

San Antonio is cheaper than the big coastal US cities. The main free sights — the Alamo grounds, the missions and the River Walk itself — carry no entry charge, so a two-day visit can be done on a modest budget. The costs below are 2026 estimates; confirm current prices before you book.

Book the Alamo church ticket and any theme-park tickets online before you arrive; walk-up slots sell out on weekends and school holidays. Downtown parking is expensive and scarce, so stay within walking distance or use the bus and rideshare instead of driving in.

Summer heat is the main planning constraint. July and August afternoons regularly push past 35 °C, so put outdoor sightseeing in the morning and use the middle of the day for museums, the River Walk's shaded stretches or a long lunch. Carry water; the River Walk is below street level and can feel hotter than the streets above.
