Los Algodones, Baja California, is a small Mexican town located on the extreme northeastern tip of the municipality of Mexicali, approximately 16 km (9.9 mi) west of Yuma, Arizona, USA. Its official name is Vicente Guerrero, and it is informally known as Molar City, because of the large number of dentists that cater to Americans. It reported a population of 5,474 as of the 2010 Mexican census. It also serves as a borough seat of its surrounding area.
Situated near the borders of both southeastern California and southwestern Arizona, Los Algodones has become a popular tourist attraction in recent years due in part to inexpensive shopping and restaurants as well as inexpensive medical care and prescription medicines. The warm, dry climate of the area attracts a number of older tourists from across the United States and Canada who settle during the winter in the nearby towns of Yuma, Arizona and Winterhaven, California. Organized day trips from the Coachella Valley are popular among seniors as well
