At around 35km wide and 120km long, Laguna de Chapala, just over 50km south of Guadalajara, is the largest lake in Mexico. Its northern shore has long been a favourite retreat for Tapatíos, especially since the early years of the twentieth century when dictator Porfirio Díaz regularly spent his holidays here. Expats from north of the border, particularly Canadians, have also been appreciative of the lake scenery and even year-round temperatures. It is said that there are now around thirty thousand such people living in and around Guadalajara, a sizeable proportion of whom have settled on the lakeside – particularly in Chapala and in the smaller village of Ajijic. Peak season is November to April, which coincides with the arrival of seasonal snowbirds.
