Cañada de la Virgen, San Miguel de Allende
Concierge.com's insider take:
Opened to the public in 2010 after years of excavation, this pre-Hispanic site, believed to have been constructed by the Otomí, peaked between AD 540 and 1050. Seven large structures including a ball court and pyramids have been uncovered, along with 19 burial sites with jade and shell necklaces, obsidian blades, and earthenware. You can visit the site on your own with a rental car, but it's more rewarding with a driver and guide from a local tour company, such as Colonial Mexico tours (52-415-152-5794).—Maribeth Mellin
