Samulá
'Cenote Samulá' from Turismo
Samulá cenote. Cenotes are (mostly) underground rivers. Though some of them are out in the open, many of them are only accessible through cave systems, formed by a badass meteor impact 65 million years ago. This is one of my favorite ones, about an hour and a half away from where I live, and like 20 minutes away from Chichen Itza. Those vine-looking things are actually the roots of a tree that's at ground level.
