Central Mexico’s Bajío region—San Miguel sits at its heart—is high mountain desert, with a landscape quite worthy of exploration. The 445-acre nonprofit nature preserve called El Charco del Ingenio—named a Peace Zone by the Dalai Lama in 2004—is a prime destination for nature lovers, thanks to miles of trails, an extensive botanical garden, and a fascinating wetlands preserve. Spend all day if time allows—an on-site café provides nourishment to keep you going.
