San Antonio Travel Guide: The Alamo, Riverwalk & Tex-Mex

San Antonio lies in south-central Texas at the intersection of Interstate 35 and Interstate 10, approximately 80 miles southwest of Austin and 190 miles west of Houston. The city sits on the Balcones Escarpment where the Hill Country meets the Coastal Plains, a geological transition zone that creates the limestone-fed springs and underground aquifers that made permanent settlement possible. The San Antonio River, fed by the Edwards Aquifer, flows through the urban core in a horseshoe bend that determines the city's historic and modern geography. Municipal population reached 1,434,625 in the 2020 census, making San Antonio the seventh-largest city in the United States and the second-largest in Texas after Houston. The metropolitan statistical area contains 2,558,143 people across eight counties. Summer daily high temperatures average 95 degrees Fahrenheit from June through August with heat index values frequently exceeding 105 degrees. Winter lows drop to the mid-40s Fahrenheit with occasional freezes. Annual rainfall measures 32.28 inches based on National Weather Service records at San Antonio International Airport. The city receives sun 220 days per year on average.

The Alamo sits at 300 Alamo Plaza in downtown San Antonio, a walled compound occupying 4.2 acres at the eastern edge of the original mission site. The limestone chapel structure that dominates photographs was built beginning in 1744 as part of Mission San Antonio de Valero, the first Spanish mission established in the region in 1718. Franciscan missionaries abandoned the mission in 1793. Spanish colonial troops occupied the site beginning in 1803, naming it after their garrison town of Alamo de Parras in Coahuila. The chapel measured 33 feet wide and 62 feet long with walls four feet thick at the base. The iconic curved parapet topping the facade was added in 1849-1850 by the United States Army, not by Spanish builders. No original roof exists. The mission housed approximately 300 Spanish-speaking residents before secularization.

The 13-day siege began on February 23, 1836 when Mexican General Antonio López de Santa Anna arrived with an army estimated between 1,800 and 6,000 men depending on the source. Texian forces numbered approximately 200 fighters commanded initially by William B. Travis and James Bowie, both of whom died in the final assault. David Crockett, former congressman from Tennessee, arrived with a group called the Tennessee Mounted Volunteers on February 8, 1836 and died in the battle. The final assault occurred before dawn on March 6, 1836. Mexican forces breached the north wall using ladders and sustained casualties estimated between 400 and 600 killed and wounded. All Texian combatants died except for approximately 20 enslaved or servant-class individuals whom Santa Anna released. Estimates of non-combatant survivors range from 15 to 20, primarily women and children including Susanna Dickinson and her daughter Angelina, who were sent to carry word of the defeat to Sam Houston. The phrase "Remember the Alamo" appeared in written accounts within weeks and became the rallying cry at the Battle of San Jacinto on April 21, 1836, where Texian forces under Sam Houston defeated Santa Anna's army in 18 minutes.

The Alamo compound today includes the chapel, the Long Barrack built in 1724 and reconstructed multiple times, and the walled plaza. The Daughters of the Republic of Texas administered the site from 1905 to 2015 under a state custodianship agreement. The Texas General Land Office assumed management in 2015. The site receives approximately 2.5 million visitors annually based on General Land Office estimates, making it the most visited site in Texas. Entry to the chapel and museum buildings is free. The site closes at 5:30 PM daily. Security screening at the entrance prohibits weapons, large bags, and professional photography equipment without permits. Visitors must remove hats inside the chapel, a policy enforced by staff. The Alamo chapel contains no original artifacts from the 1836 battle inside the building itself. Most historical artifacts including weapons, documents, and personal effects are displayed in the Long Barrack Museum and the newer exhibition spaces opened in recent years. The cenotaph monument erected in 1939 stands in Alamo Plaza in front of the compound entrance. The limestone memorial measures 60 feet tall and lists the names of those confirmed killed during the siege and battle.

The San Antonio River Walk extends 15 miles through the city along both banks of the San Antonio River, though the term typically refers to the 2.5-mile downtown horseshoe loop between Lexington Avenue and South Alamo Street. Architect Robert Hugman designed the initial downtown section as a Works Progress Administration project begun in 1939 and completed in 1941. The city built limestone retaining walls 14 to 20 feet below street level, creating a flood control channel that doubled as a pedestrian corridor lined with native cypress trees, restaurants, bars, hotels, and retail spaces. The 1968 HemisFair exposition spurred expansion. The Museum Reach extension opened in 2009, adding 1.3 miles from downtown north to the San Antonio Museum of Art and Pearl Brewery complex. The Mission Reach extension opened in 2013, adding eight miles from downtown south to Mission San Juan, passing three other Spanish colonial missions along the way. The entire linear park system now covers approximately 15 miles.

The downtown loop contains approximately 200 commercial establishments including 50 restaurants, 30 bars, 20 hotels, and numerous retail shops based on surveys conducted by the San Antonio River Walk Association. Dining tables and chairs sit directly adjacent to the water on stone walkways and limestone terraces. Paso del Rio, the original Spanish name for the river walk project, appears on historical markers throughout the system. Water depth in the downtown channel averages four feet during normal flow conditions. The San Antonio River Authority controls water levels through upstream dams and gates at the Olmos Dam completed in 1926. River barges operated by several private companies carry tourists on 35-minute narrated loops through the downtown horseshoe section. Barge capacity ranges from 30 to 40 passengers. The river walk floods during heavy rain events despite the Olmos Dam. Major floods occurred in 1998, 2002, and 2013. The 1998 flood closed the river walk for three weeks. Bypass tunnels completed in 1997 and 2004 divert floodwaters around the downtown section but do not eliminate all flood risk.

The river walk operates 24 hours daily. The San Antonio Police Department maintains a river walk division with officers on foot, bicycle, and boat patrol. The downtown section draws estimated annual visitor counts of 11.5 million based on economic impact studies commissioned by the city in 2019. December visitation peaks during the holiday season when the San Antonio River Walk Association installs approximately 100,000 lights along the 2.5-mile downtown corridor. The Fiesta River Parade held each April since 1941 features decorated barges carrying participants from local organizations, military units, and civic groups. The parade route covers 2.5 miles and takes approximately two hours. Spectator capacity along the route reaches approximately 250,000 based on fire marshal estimates for the 2019 event. The river walk contains no swimming areas. Water quality testing by the San Antonio River Authority measures bacterial counts that exceed recreational contact standards during and after rain events. Signs posted at intervals along the walkway prohibit water contact.

Tex-Mex cuisine in San Antonio developed from Tejano cooking traditions modified by Anglo-American preferences beginning in the late 19th century. The term Tex-Mex entered print in 1963 describing border railroad routes and was applied to food by the 1970s. San Antonio claims the first recorded commercial Tex-Mex establishments including the Original Mexican Restaurant opened by Otilia Garcés in 1900 and the Vogue opened by J.C. Gonzales in 1932, though historians debate which establishments genuinely qualify as first. The defining characteristics of Tex-Mex distinguish it from northern Mexican cuisine through heavier use of yellow cheese, wheat flour tortillas, cumin, beef, and chili powder combinations not typical in Mexican regional cooking. San Antonio Tex-Mex specifically emphasizes puffy tacos, breakfast tacos, and combination plates.

The puffy taco originated at Ray's Drive Inn in San Antonio in 1978 according to documented accounts from the Mares family who operated the restaurant. The taco shell is raw corn masa pressed thin, dropped into hot oil at 375 degrees Fahrenheit where it puffs within 15 seconds, then filled while still warm with ground beef, lettuce, tomato, and cheese. The technique differs from frying pre-formed hard taco shells. Ray's Drive Inn at 822 SW 19th Street closed in 2021 but multiple San Antonio establishments now serve puffy tacos including Henry's Puffy Tacos opened in 1978 by Henry Lopez at 6030 Bandera Road. The breakfast taco format, a flour tortilla filled with scrambled eggs and additional ingredients, has no single origin point but proliferated through San Antonio taquerías and convenience stores beginning in the 1950s. Common fillings include eggs with chorizo, bacon, potato, or beans. Taquerías open as early as 5:00 AM. Prices range from two dollars to five dollars per taco.

The combination plate format, typically including an enchilada, taco, rice, and refried beans served on a single platter, standardized in San Antonio restaurants during the mid-20th century. Mi Tierra Café y Panadería at 218 Produce Row in the Market Square area opened in 1941 and operates 24 hours daily. The restaurant seats approximately 500 guests across multiple dining rooms and an outdoor patio. Mariachi bands perform continuously during operating hours, rotating musicians every 30 minutes. The attached bakery produces pan dulce, conchas, empanadas, and tres leches cakes. Market Square itself, also called El Mercado, occupies three blocks bounded by Commerce Street, Santa Rosa Street, Dolorosa Street, and Interstate 35. The market contains approximately 100 vendors selling Mexican imports, crafts, and food. Farmers Market Plaza and the Mi Tierra complex anchor the western edge. The National Historic Landmark designation applied in 2015 covers the market structures built in 1938 as a Works Progress Administration project.

San Antonio enchiladas differ from interior Mexican versions by using chili gravy rather than mole or salsa verde. The gravy base combines beef stock, wheat flour roux, chili powder, cumin, and garlic. Corn tortillas are dipped in the gravy, filled with cheese or ground beef, rolled, plated, covered with more gravy and shredded yellow cheese, then baked until the cheese melts. The dish appeared on San Antonio menus by the 1920s. Jalapeños served with Tex-Mex meals in San Antonio are typically pickled en escabeche rather than fresh. The pickling liquid contains vinegar, carrots, onions, and bay leaves. Fresh jalapeños measure 2,500 to 8,000 Scoville heat units. Serrano peppers, occasionally substituted, measure 10,000 to 23,000 Scoville units.

Fajitas as a commercial dish originated in South Texas during the 1970s though the practice of grilling beef skirt steak over mesquite dates to ranching communities along the Rio Grande in the early 20th century. The word fajita derives from faja meaning belt or strip, referring to the skirt steak cut from the diaphragm muscle. Ninfa's restaurant in Houston claims the first menu listing in 1973, but San Antonio restaurants including the Roundup on Broadway and El Mirador on South St. Mary's Street served similar preparations by the mid-1970s. The commercial format presents grilled marinated skirt steak sliced against the grain, served on a sizzling cast iron skillet with grilled bell peppers and onions, accompanied by flour tortillas, pico de gallo, guacamole, sour cream, and shredded cheese. Chicken fajitas appeared on menus by the early 1980s as a lower-cost alternative. Skirt steak prices tripled between 1990 and 2010 as fajitas gained national popularity and demand increased.

Chili con carne as served in San Antonio derives from chili queens who sold the dish from outdoor stands in Military Plaza and Alamo Plaza during the late 19th century until health regulations shut down the stands in 1937. The San Antonio version contains beef, dried chili peppers, cumin, garlic, and sometimes masa for thickening, but never beans in traditional preparation. Beans served alongside are acceptable, but adding beans to the chili itself remains contentious among traditionalists. The Original San Antonio Chili Stand operated at the 1893 World's Columbian Exposition in Chicago, introducing the dish to a national audience. Multiple San Antonio establishments claim original recipes including Gebhardt's Chili Powder Company founded by William Gebhardt in 1896, which began selling packaged chili powder after Gebhardt developed a process for drying and grinding peppers. The factory operated in San Antonio until 2009.

Barbacoa in San Antonio specifically refers to beef cheek meat, not whole animal barbecue. Traditional preparation wraps the seasoned meat in maguey leaves and steams it overnight in an underground pit, though commercial operations use above-ground steamers. The meat is shredded and served in tacos with cilantro, onion, and salsa on corn tortillas. Garcia's Mexican Food at 842 Fredericksburg Road and Ray's Drive Inn served barbacoa primarily on weekends when demand justified the long cooking time. The dish appears on weekend-only menus because preparation requires 8 to 12 hours and the meat does not hold quality beyond 24 hours. Cow head barbacoa, including brain and tongue, was standard until health regulations restricted sales of certain organ meats in the 1990s. Beef cheek meat now dominates commercial preparation. Prices range from three dollars to five dollars per taco.

Flour tortillas in San Antonio Tex-Mex restaurants are made fresh throughout the day using wheat flour, vegetable shortening or lard, salt, baking powder, and water. The dough rests 20 to 30 minutes, then is portioned into balls weighing approximately two ounces each, rolled thin with a wooden rolling pin or pressed in a mechanical tortilla press, and cooked 30 seconds per side on a flat griddle called a comal heated to 450 degrees Fahrenheit. Homemade flour tortillas distinguish higher-end Tex-Mex restaurants from fast-casual operations that purchase pre-made tortillas from commercial suppliers including H-E-B Bakery and Mission Foods. A single cook can produce approximately 100 tortillas per hour by hand. Corn tortillas are less commonly made in-house, with most restaurants purchasing from local tortillerías.
