Mexico · Dos Ojos/Sac Actun

The Pit

Also known as: El Pit

Best time to dive

January to December

Certification & difficulty

Technical - advanced conditions (currents/depth); dive within your training.

Snorkelling

Snorkel-friendly - yes - a separate surface-snorkeling product is offered at the cenote, distinct from the deep AOW cavern dive

Safety notes

permanent overhead/cavern environment with a mandatory permanent guideline; cavern-trained guide required (max ~4 divers per guide per one operator); buoyancy control critical to avoid silt-out; hydrogen-sulfide layer toxicity-if-disturbed is chemically plausible but not specifically documented as an incident at this site; operator claims of ancient human/fossil remains found in The Pit itself could not be verified against peer-reviewed sources and likely conflate it with the separately-documented Hoyo Negro/'Naia' find in a different cenote (Sistema Aktun Hu) - flag as unverified marketing claim, not scientific fact

Permits & fees

Dos Ojos/Sac Actun cenote system entrance fee applies (The Pit is gated under the Sac Actun ejido, potentially a separate fee line from the main Dos Ojos gate); exact current MXN amount could not be verified this session - VERIFY via operator pricing pages before publishing a figure

Permits and operators change - confirm before booking.
