Presa de la Olla is a historic reservoir on the edge of Guanajuato, built to help supply water to the city and now used as a leafy promenade area. Its appeal is calmer than the centre's alleys and plazas, with water, trees, and old villas softening the city's mineral-town intensity.
Come for a stroll when you want a break from the crowded historic core. The reservoir is also tied to local festivities and civic history, so it works as a small but useful addition to Guanajuato's better-known churches, mines, and viewpoints.
