Four days to cover San Antonio properly — the Alamo and River Walk, the Mission Trail by bike, the Pearl District, McNay Art Museum, and the San Antonio Museum of Art. Enough time to get past the tourist infrastructure and understand why this city has been continuously inhabited since 1718.
Arrive, check in, and get to the Alamo before the heat peaks and the crowds swell. Afternoon on the River Walk south toward King William. Dinner in King William neighborhood.
The Alamo compound opens at 9am. The Long Barrack museum east of the chapel is the most substantive interpretive space — it covers the full history from 18th-century Spanish mission through the 1836 battle with period weapons, documents, and artifacts. The chapel is the iconic image: spare limestone walls, arched facade, the curved parapet. The grounds are small enough to cover thoroughly in 90 minutes if you arrive at opening. The gift shop and the plaza outside fill with tour groups starting at 10:30am. Free admission to grounds; suggested donation for Long Barrack museum.
The full River Walk from the Museum Reach (north of downtown, past the San Antonio Museum of Art) through the commercial district and south to the beginning of Mission Reach covers about 5 miles of flat limestone path. The Museum Reach past the blue and white mosaic-tiled pumping station is the most architecturally interesting stretch; the commercial section through downtown is the busiest; the King William bend south of the Convention Center is the most peaceful. Walk at whatever pace feels right — there is no wrong direction. Free.
Southerleigh occupies the original pearl brew kettles in the Pearl's brewhouse — the copper fermentation vessels are mounted in the dining room walls, the ceiling is raw industrial, and the beer list is brewed in-house with serious Gulf Coast and Texas craft influences. The menu leans Gulf seafood and Texas-raised proteins: oysters on the half shell, Gulf shrimp and grits, wood-fired fish. The Southerleigh Lager and the seasonal ales are the right drink choice. Dinner for two without drinks runs $70–100. Reservations recommended for evening seatings.
Rent bikes at the Pearl or downtown and ride the Mission Trail south — four Spanish colonial missions, all active parishes, strung along a 10-mile car-free path. San José is the anchor; Concepción has the most intact frescoes; Espada is the most remote and least visited. This is the best day of the trip.
Mission Concepción (formally Nuestra Señora de la Purísima Concepción) is the first mission on the trail south of downtown and the oldest unrestored stone church in the United States — the exterior limestone walls and interior frescoes date to 1755 and have not been structurally altered. The geometric pattern frescoes in the sanctuary interior were rediscovered in the 1990s when whitewash was removed; the colors are still present in sections. The compound grounds include the original convento and the outline of the mission quadrangle. This is the most architecturally significant stop on the trail. Allow 45–60 minutes.
The two southernmost missions — San Juan Capistrano and San Francisco de la Espada — are the least visited and the most peaceful. San Juan's small chapel and the partially reconstructed granary complex sit in a flat floodplain near the river; Espada, another 2 miles south, is the most remote and has an operational acequia (irrigation canal) that still carries water — the only functioning acequia from the colonial Spanish period in the country. Both are still active parishes. Allow 30–40 minutes at each. The ride back north from Espada to the Pearl is about 12 miles along the river path — flat, mostly shaded after 3pm.
Two excellent museums on Day 3 — the McNay in the morning (Marion Koogler McNay's Spanish Colonial mansion and its Impressionist and Post-Impressionist collection) and the San Antonio Museum of Art in the afternoon (the strongest Latin American art collection in the US). Market Square and Mi Tierra for dinner.
The McNay Art Museum occupies Marion Koogler McNay's 1929 Spanish Colonial Revival mansion in the Alamo Heights neighborhood north of downtown — 24 acres of courtyard gardens and a 24,000-square-foot house converted to gallery space. The collection is strongest in 19th and early 20th-century European work: Picasso, Cézanne, Van Gogh, Gauguin, Mary Cassatt, and significant holdings in American modernism. The theater arts collection (set designs and costumes from Broadway productions) is an unexpected highlight. The architecture and the courtyard garden are worth the visit independently. Admission is $20/person. Allow 90 minutes.
The San Antonio Museum of Art (SAMA) occupies the 1884 Lone Star Brewery on the Museum Reach of the River Walk — the industrial brick building is a successful adaptive reuse and the interior galleries follow the original brewery layout. The Latin American collection is the standout: pre-Columbian ceramics and gold work, colonial Spanish viceregal painting, and 20th-century Latin American modernism with depth in Mexican muralism. The ancient Mediterranean collection (Egyptian, Greek, Roman) is also strong and larger than expected. Admission is $15/person. Allow 90 minutes.
Mi Tierra has been operating 24 hours a day at Market Square since 1941 and is the most San Antonio restaurant experience available. The interior is covered floor to ceiling with Christmas lights and decorations year-round; the panaderías counter at the entrance sells pan dulce around the clock; mariachi bands circulate through the dining room during evening hours. The enchiladas verdes and the caldo de res are honest and reasonably priced; the chile relleno is the best item. Order a margarita and pan dulce to close. Dinner for two runs $40–60. No reservations — walk in at any hour.
Final morning at the Pearl Saturday farmers market if the schedule allows, a quiet stop at San Fernando Cathedral (oldest cathedral in the US, active parish), then depart. Alternatively use the morning for Brackenridge Park and the San Antonio Zoo for families.
San Fernando Cathedral on Main Plaza was established in 1731 by Canary Island colonists — the original foundations are beneath the current 19th-century Gothic Revival structure, making it the oldest continuously operating cathedral in the US. The cathedral is an active parish with multiple daily masses and is not a museum — enter quietly, respect the active worship space, and spend 20 minutes in the nave. The light through the stained glass in the morning is extraordinary. Free. Main Plaza outside the cathedral is the original town square of San Antonio; the stone buildings surrounding it are worth noting.
The heat from June through September is genuine — June can hit 105°F and the limestone riverbanks trap it. Plan outdoor activity before 10am or after 7pm in summer; the Mission Trail by bike is a dawn ride in July. Spring (March–April) is the ideal window: mild temperatures, wildflowers in the Hill Country 45 minutes north. Fiesta SA in late April is worth attending but book hotels six months out. Uber/Lyft covers most ground but a car opens the Hill Country, which is a half-day worth adding. The B-cycle bikeshare network covers Pearl-to-downtown reliably. Most River Walk restaurants are mediocre tourist traps — eat one meal there for the experience and use the rest of this guide for the real food.
