Cenote Angelita is the #1 choice by freediving schools around Tulum and Playa for their classes. It is a typical "jungle cenote", a warm clear pool of water surrounded by dense rainforest.
Angelita began as an underground cavern, until one big tree in the jungle above drank so greedily from its water that its roots cracked the limestone ceiling of the cavern, opening the cenote to the world and plunging the tree to its doom. Today, this tree can still be seen, lying petrified in the middle of the cenote about 30 meters down.
At this same depth of 30 meters, fresh water above meets salt water below, and in between them lies a sulphur layer, the by-product of vegetation breaking down. This sulphur layer creates an eerie underwater cloud from which the tips of the tree's branches emerge. Part of the short film about freediving One Breath
is set here.
On any given day you can find classes from several different freediving schools training here. The water is warm, visibility is great, it has 30m of freediveable depth, plus it is only a 15 minute drive from Tulum.
