The Toltec capital, north of the city in Hidalgo. The stone warriors standing on top of the pyramid are what people come for.
Open every day, 9:00 to 17:00, with last entry at 16:00. Entry is $210 pesos, or $105 with Mexican residency. There's a site museum here as well as the ruins.
TODO: how we're getting there.
TODO: whether this is instead of Teotihuacan or as well as it — two pyramid days in one trip may be one too many.
