Unmissable Mayan archaeological ruins.
Try to go there in a period when the heat isn't yet suffocating, or very early in the morning.
As I hadn't read a lot about it I was expecting a really big site, like Tikal. In fact, Palenque
is less striking for its enormous size than for its interesting carvings. I recently read that only 2% of the site has been explored to date (that is, a visitable area of 2.5km²). For comparison, the gigantic Tikal has a surface of 18 km².
I particularly remember the tower of the Palace (the Observation Tower). I don't think I have seen the like on other pre-Hispanic sites that I have visited in Meso-America. I thought the most interesting part was the Temple of the Inscriptions, which houses the tomb of King K'inich Janaab' Pakal, probably because I had never been inside
a pyramid before. Its welcome freshness gave me a few moments respite from the suffocating heat of the place.
