A few years ago I climbed to the top of a pyramid in Mexico. It was really steep and hot and my legs started shaking halfway up but once on top there was a great view of all the Mayan ruins in the park. Went back last year and all of the pyramids were roped off. I guess people climbing on them is causing too much destruction.

How I did it: Went on a school trip with NYU and one of our destinations was the pyramids. It was actually kinda scary, space is tight as they weren't necessarily built for people these days nor as a travel destination.
