A pleasant day trip from Mexico City, this small site of ruins that were once the capital of the Toltec empire (AD 900-1150) has several temples topped by giant stone carvings of stern-faced warriors. They form a terrifying spectacle, and it is easy to see why the Aztecs destroyed the ruins. There's a small ball court and restored temple on the site. 45 mi/70 km north of Mexico City.
