Palenque's ruins are some of the most lucious Mayan ruins out there. The entire place is surrounded by a mystical closeness to its ancient history. Archaeologists & guides say that the place is guarded by the ancient habitants at night & can be seen in the form of spirits. It costs about 100 pesos to get in, and it comes with dope ruins & waterfalls (but you can't swim here). Go & linger. Take a notebook to draw the beauty.
