So what are cenotes? To put it simply they are sinkholes full of waters. Yucatan was under the surface of the sea along with the limestone. View now built upward from fossilized coral and the seafloor. After the peninsula began to grow above sea level underwater rivers began to construct a caving program.
The caves bombarded which allowed divers now to float around these early formations. In certain caves and caverns even early Mayan pottery and bones are available.
What's unique about cavern diving? From the cenotes you will be diving into caverns, this usually means you will be in an overhead environment. For security reasons your manual is a completely trained cave diver with specific equipment and won't ever guide over 4 individuals. If she or he participates using one tank that usually means that security standards are not met and you shouldn't dip with this manual.

Cavern diving usually means you will never be farther than 40m from the surface, so you may always see natural lighting and you won't go into a cave. Entering a cave method to swim within a pit where you'd need to turn around to get outside again.
Scuba diving in caverns is similar to overhangs and swim-throughs. Throughout the dive, the team is after a line to be certain no one becomes dropped or moves a lot away from the entry. The sole additional equipment you need to bring to a cavern dive is a dip flashlight (or even in case you have got a spare one, better attract 2 ). Aside from the light, you will not require any special gear.
