I always wanted to visit the ancient site of Teotihuacan, this place is an ancient city named after where gods are born. It’s really stunning what mankind were able to built over 2000 years ago.
There are two main Pyramids, (Not actually Pyramids, since they are not hollow buildings). They are massive buildings mostly used to human and animal sacrifice. One is the temple of the sun, and another temple (the one in the middle) is called the pyramid of the moon.
You are allowed to climb both Pyramids, the stairs are very tough to walk on though and once you’re finally up the view is amazing.
I would recommend everyone who will be in Mexico City, to book a tour to Teotihuacan. It will take around 1,5 hours to drive up there. But it is worth it!
We arrived early in the morning, so it was quite calm, but expect lots of crowds later. There is also the possiblity of getting inside a hot air balloon.
