- [Julien] When you enter a cenote

it's really like going into another world.

Like leaving the planet behind.

This is a feeling of really exploring something new.

And I feel very lucky to be able to see that.

My name is Julien Borde.

I've been free diving and scuba diving

for the last 15 years.

Going many different location,

always trying to find the best diving spot.

(water gurgling)

Though cenotes are caves,

all the cenotes are connected to each others.

And the water goes and flows

from one cenote to another cenote to end up in the sea.

(ethereal music)

The first time you go into a cenote

it's something you don't see anywhere else.

It's completely different experience

than diving in the ocean.

At the beginning it can be a little bit scary.

But really quickly,

the beauty of the place will just take over.

(chimes ringing)

Some cenotes are very welcoming,

sometimes, so big and so clear,

that it really gives you the sensation

you go into a church and you don't want to talk too loud

to not disturb anyone.

And some of the cenotes are really so polluted like

an atmosphere more like hell

with dead trees on the bottom and sulfur.

The Mayans were using the cenotes

for a very long time.

Basically the land where we are

that's the place where the living people lives

and then underneath the cenotes,

into the ground was the place for the dead.

Every cenote have a different personality,

but I also think that here you affect your own personality.

(ethereal music)

At some point you kind of enter into like a meditation state.

It is, for me, completely priceless.
