The Historic Hipodromo Aguacaliente Casino Today, following in this rich tradition, the Casino Hipódromo de Aguacaliente continues to offer visitors all the premium amenities and excitement of a modern casino while preserving the historic charm and character of its prohibition-era predecessor. When the lavish Agua Caliente Casino and Resort opened its doors in 1928, it became a haven from prohibition for wealthy Americans and Hollywood celebrities alike as they flocked across the San Diego border to Tijuana to drink, place bets, and take in the excitement of the racetrack.
