Casino Morongo originally opened back in 1995 and in 2004 when the significantly larger Morongo Casino, Resort and Spa was completed, it moved its table games and slots out and has reportedly been used primarily for special events, bingo and bowling in recent years. The two casinos operate across from the other on Seminole Drive in Riverside County. In Southern California, the Morongo Band of Mission Indians has reopened the original Casino Morongo, in Cabazon as the expansion of the Morongo Casino, Resort and Spa is underway.
