Dos Ojos Cenote: Explore the Barbie Line & Bat Cave in Tulum’s Famous Cavern System
A Must-Dive for Certified Open Water Divers — Light Beams, Stalactites, and Hidden Caves Await
Dos Ojos, meaning “Two Eyes,” is one of the most iconic and visually spectacular cenotes in the Yucatán Peninsula. Located just outside Tulum, this vast underwater cavern system is known for its crystal-clear water, mind-blowing rock formations, and surreal light effects. At Flying Fish Tulum, we offer guided dives on two distinct lines in Dos Ojos: the Barbie Line, a gentle, scenic route perfect for a first cavern dive, and the Bat Cave, a darker, more adventurous line with a visit to an air-filled dome.
These dives are suitable for Open Water certified divers, with no cave certification required. Our experienced guides take you safely through these awe-inspiring caverns while you glide past towering stalactites and navigate through sunlit underwater tunnels.

Why Dive Dos Ojos?
At Flying Fish Tulum, we guide two spectacular dive routes at Dos Ojos:
The Barbie Line
The Barbie Line offers a wide, well-lit circuit with stunning rock formations, stalactites, and huge limestone columns. Sunlight streams in from the surface, creating dramatic beams of light as you swim through this underwater cathedral. The open spaces and excellent visibility make this a perfect introduction to cenote diving for Open Water divers.
The Bat Cave
The Bat Cave route leads into darker overhead areas where you’ll surface inside an air-filled dome inhabited by bats. This dive offers a slightly more adventurous experience, with narrower passages and impressive stalactite formations. While still accessible to Open Water divers, strong buoyancy control is important.
