This fabulous archaeological zone lies in a mountain-ringed offshoot of the Valle de México. Site of the huge Pirámides del Sol y de la Luna (Pyramids of the Sun and Moon), Teotihuacán was Mexico's biggest ancient city and the capital of what was probably the country's largest pre-Hispanic empire. A day here can be awesome - don't let the hawkers get you down. Bring a hat, water and your walking shoes.
The site's main drag is the famous Avenue of the Dead, a monumental thoroughfare lined with the former palaces of Teotihuacán's elite. To its south is the pyramid-bedecked La Ciudadela, believed to have been the residence of the city's supreme ruler. Enclosed within the citadel's walls is the Quetzalcóatl Temple, with its striking serpent carvings.
Heading north, you pass the world's third-largest pyramid: the awe-inspiring, 70m (230ft), 248-stepped Pyramid of the Sun. The avenue terminates at the Pyramid of the Moon, flanked by the 12 temple platforms of the Plaza de la Luna. Nearby are the beautifully frescoed Palace of the Quetzal Butterfly, the Jaguar Palace and the Temple of the Plumed Conch Shells. Teotihuacán's most famous mural, the Paradise of Tláloc, is in the Tepantitla Palace, northeast of the Pyramid of the Sun. There's a museum to help make sense of it all.
