The Agua Caliente Casino is a gambling facility, run by the Agua Caliente Band of Cahuilla Indians, in Rancho Mirage, California. The facility has over 45,000 square feet (4,200 m2) of gambling floor. The casino completed a 16-story, 173-foot (53 m) hotel tower which opened on April 18, 2008. The tower is the third-tallest building in the Inland Empire. The paved and landscaped parking lot on the property was, nearly 40 years before, a sandy patch of desert, across which Jonathan Winters drove a moving van, in the film It's a Mad, Mad, Mad, Mad World.
