Teotihuacan, an Aztec site where the height of the Pyramid of the Sun and the Pyramid of the Moon gives a sense of the scale of this city, the largest in the pre-Columbian world. Rise above it all aboard a hot air balloon to admire the beauty of the archaeological site and take in the surrounding landscape. When the sun is still low, it's the ideal moment to drift gently above Teotihuacan, whose name curiously means “the place where the gods were created”, or “the city where men become gods”.
