Agua Caliente: The Tijuana resort that made San Diego a gateway to glamour

Today, Las Vegas may be the city most associated with casino resorts, but decades earlier, San Diego’s border region offered its own version of glamour. In the 1920s, San Diegans didn’t have to travel to Las Vegas for a taste of luxury, entertainment, and excitement.

They only had to head south.

Across the international border in Tijuana, the Agua Caliente resort became one of the most glamorous destinations in North America, attracting visitors from San Diego, Southern California, and Hollywood during an era when crossing the border was part of the adventure.

Built in 1928, Agua Caliente was far more than a casino. The ambitious resort combined a hotel, restaurants, gardens, swimming pools, entertainment venues, a casino, golf course, and other recreational attractions into one carefully designed destination. A horse-racing track was added in December 1929.

It offered an early glimpse of the destination-resort culture that would later become synonymous with places such as Las Vegas.

San Diego’s backyard getaway

Agua Caliente’s success was closely tied to the growth of tourism on both sides of the border.

Following the 1915 Panama-California Exposition, San Diego increasingly promoted itself as a destination for visitors. Improved roads and the growing popularity of automobile travel made Tijuana an easy excursion, while the city’s location just north of the international border put Agua Caliente within easy reach of San Diegans and other Southern Californians.

During Prohibition, when alcohol was illegal in the United States, Tijuana also offered visitors an escape from restrictions at home.

Gambling and other forms of entertainment available across the border added to the attraction. Historical research describes Agua Caliente as drawing an affluent California clientele, particularly from the film and oil industries.

For San Diegans, Tijuana was not a distant destination. It was a nearby international escape.

A resort built around the experience

Agua Caliente was designed as a complete leisure environment.

Visitors could stay at the hotel, dine in elegant restaurants, relax in landscaped gardens, swim, attend entertainment events, play golf, and visit the casino — without ever having to leave the sprawling property.

The architecture emphasized atmosphere and experience. Courtyards, terraces, and outdoor spaces connected different areas of the complex, encouraging guests to spend hours enjoying the surroundings.

Historic photographs show guests dining outdoors among landscaped gardens, lounging in the lobby, and reflecting the resort’s emphasis on elegance, relaxation, and social life.

Agua Caliente was not simply a place to gamble. It was a place to be seen.

Hollywood crossed the border

The resort quickly developed a reputation as a glamorous playground for entertainers, wealthy travelers, and celebrities.

For Hollywood figures, Agua Caliente offered an international getaway within relatively easy reach of Los Angeles and San Diego. Its combination of luxury accommodations, nightlife, recreation and entertainment made it a natural attraction during Hollywood’s Golden Age.

Among those connected with the resort was Margarita Cansino, who performed there as a young dancer before becoming Hollywood star Rita Hayworth.

The racetrack expands the spectacle

Agua Caliente was not Tijuana’s first racetrack. The earlier Sunset Inn track was already attracting crowds by the 1920s, part of a growing entertainment scene that drew visitors across the border. Agua Caliente later took horse racing to a much grander scale with its new track, which opened in December 1929.

The resort’s appeal reflected the close relationship between Southern California’s growing entertainment industry and the attractions available just across the border.

The Agua Caliente Jockey Club opened its new horse-racing track in December 1929. The modern facility could accommodate tens of thousands of spectators and immediately became another major attraction.

Horse racing brought another audience to the complex and strengthened its reputation as a destination built around leisure and spectacle. Together, the hotel, casino, racetrack and other amenities created a self-contained world designed to keep visitors entertained.

The resort also became an important part of Tijuana’s tourism economy, helping draw visitors whose spending supported businesses throughout the city.

A glamorous era comes to an end

Agua Caliente’s success depended heavily on the conditions of its time.

In 1935, Mexican President Lázaro Cárdenas moved to prohibit gambling in Mexico. On July 20, 1935, Tijuana’s casinos, including the Salón Dorado at Agua Caliente, were ordered closed. The resort company argued that the complex could not remain economically viable without gambling, and ultimately suspended its operations.

The property later served other purposes, including as an educational institution. The city of San Diego’s digital archives note that the Agua Caliente complex reopened as a school in 1939.

Although the original resort eventually disappeared, its legacy remained.

Agua Caliente helped popularize an idea that would later become central to American tourism: the destination resort, where lodging, dining, entertainment, and recreation were combined into one immersive experience.

For a brief, remarkable era, the road south led not just to another country — but to one of the most talked-about resorts on the continent.
