Mexico City's Historical Center is a must to explore!
A part of Mexico's history. Good place to walk around and see the pyramids. You can hike them, and also get in a hot air ballon.
More historic places!! Relaxing and fun.
A must! You can hike to Chapultepec's Castle where many historical people used to live, and enter as it is now a museum. Entrance: $5-6 per person. Fun fact: in Mexico's history, "six boys heroes" millitary cadets, were fighting against invadors from the US in 1847, and one of them fell from this castle trying to fight and save Mexico's flag.
