Lying nearly 50 kilometres northeast of Mexico City, the Teotihuacan Ruins are all that is left of a once mighty city, thought to have been constructed around the year 100 BC, which at its peak was home to as many as 100,000 inhabitants. Today, you can explore this archaeological site which spreads across nearly 3,400 hectares, stopping off to marvel at its towering pyramids as well as appreciating its stunning temples and murals.
The three largest structures which rise high above the site are its biggest draws: the Pyramid of the Sun, the Temple of Quetzalcoatl and the Pyramid of the Moon. The Pyramid of the Sun is the world's third-biggest pyramid, and was where the locals in this old city believed that the earth was created. Climb its 248 steps to the summit, where you'll be rewarded with a panoramic view across the whole site. Bear in mind that the hike up the steps can be challenging, but you'll be able to pause on the way up.
Walk along the three-kilometre-long Avenue of the Dead, the main passage which takes you through the heart of the city. As you explore, you'll get to see for yourself just how extensive this old city was. Spot the striking jaguar depicted on the avenue's wall – a mural which would have stretched along the whole length of the avenue when this spot was inhabited.
To the south of the avenue, have a look around the Temple of Quetzalcoatl, appreciating the beautiful stonework of the buildings. Take photos of the large serpents which you'll see carved into the rock. On the north side, meanwhile, you’ll find the Pyramid of the Moon, which you can climb for a commanding view of the avenue.
Once you've explored the ruins, pay a visit to the Teotihuacan Museum, where you can admire some more recent archaeological finds, from striking tombs and sculptures to carefully crafted jewels and necklaces.
The Teotihuacan Ruins can be reached by taking a bus that runs every 30 minutes from Terminal Central de Autobuses del Norte in Mexico City. You can eat a picnic around the ruins, though bear in mind there are few shaded areas so bring some sun protection too. You can also have lunch at the museum's restaurant.
