Balneario Comanjilla is a historic hacienda-style thermal resort in Comanjilla, León municipality of Guanajuato State, where naturally warm calcium-rich thermal springs have been developed into a traditional Mexican balneario in the style of the grand haciendas that characterised the silver-mining wealth of the Bajío region during the colonial and Porfirian eras. The resort's large outdoor thermal pools, fed by naturally warm calcium-rich waters in a garden setting of bougainvillea and laurel trees, attract families from across the Guanajuato-León metropolitan area for day visits and weekend stays in one of Mexico's most enjoyable traditional hot spring resort experiences. The Bajío region — heartland of Mexico's War of Independence (Guanajuato, San Miguel de Allende, Dolores Hidalgo) and the artisan and colonial city of Guanajuato itself, a UNESCO World Heritage Site — provides an incomparably rich historical and cultural landscape for thermal tourism. Balneario Comanjilla's combination of thermal spring bathing, hacienda heritage architecture, and proximity to Mexico's most celebrated colonial and baroque cities makes it a natural complement to cultural tourism in the Guanajuato highlands.
