The next day, I went to Chapultapec Palace and then checked out some other museums. The Palace was cool with some awesome views of the city. I checked out a few other museums, including Frida Kahlo's museum. Frida Kahlo is a famous Mexican artist. She has a really interesting story, so I'd recommend reading more about it online and checking out her work if you are in Mexico City. This is the one museum I think you should check out.

At this point, I realized I had too much time in Mexico City. You really could spend weeks in Mexico City as there is a lot to discover but if you're not living there, I think you need a change of scenery after 5-6 days if you are travelling alone. There were also enough museums for you to become a historian but at a certain point, you can only see so many museums.
