Scuba Diving Cenote Angelita: Experiencing Underwater Rivers

Cenote Angelita is a hidden gem of the Mexican Yucatan Peninsula. Beneath the cenote lies an underground river flowing with extraordinary beauty. This unique phenomenon is created by hydrogen sulfide that divides freshwater and saltwater. The density is heavier than salt water, which makes it fall to the bottom and form a distinct layer that flows like any other river.

About cenote Angelita

Located in the Tulum region of Mexico, Cenote Angelita is part of a network of underground caverns and cenotes that reach depths of up to 200 feet (60 meters) and has an 82 feet diameter (25 meter). Angelita means Little Angel in English. And it’s hands-down one of the best dive sites in Tulum.

The water here is clear but has a greenish tint with spots of visibility reaching between 33 and 100 feet (10 and 30 meters) – on average 33 ft (10 m). At these depth levels, you can observe fish swimming around, and stunning rock formations formed by the gradual accumulation of minerals through time.

At 90 feet (27 meters) there is the famous halocline, looking like a cloud or even like the ground, with trunks and branches reaching through the hydrogen sulfide layer.
