Nitrox diving at cenotes Azul Ha and Zapote
This is the trip for the cenote diver who already knows the environment and wants more time down there. On Nitrox we extend bottom time across two deep cenotes: Azul Ha, with crystal water and sharp light contrast, and Zapote, with its Hell's Bells hanging inside the halocline.
What makes this dive different
- Nitrox to maximise bottom time at depth
- Azul Ha: deep cenote with crystal water and strong light contrast
- Zapote and its Hell's Bells beneath the halocline
- Very small group with a deep-cenote specialist guide
- Entrance fees, permits and Nitrox fill included

FAQ
Frequently asked questions
What does Nitrox add in a cenote?
By reducing the nitrogen fraction it extends the no-decompression limit at these depths. In practice: more minutes down there and less post-dive fatigue.
What if I do not have the Nitrox certification?
We can run the PADI Enriched Air speciality before the trip; it is a short course with no mandatory dives. Message us and we will arrange it.
Can I do it without Nitrox?
A non-Nitrox version of Zapote is available on the Kin Ha + Zapote trip. This trip is designed specifically around the mix.

“Excellent experience! Rene is a brilliant guide — you can tell he loves what he does and passes on his passion for the sea and marine life at every moment. His instructions and dive plan before every dive make you feel safe and let you enjoy the flora and fauna even more. Highly recommended, I already want to plan new dive trips!”

“I had an excellent experience with Scuba & Adventours Mexico starting my PADI Open Water Diver certification. Everything was explained very clearly and all my questions were answered along the way. Instructor René has a real talent for explaining things simply and clearly.”

“My first time in the diving world! I'm so grateful because my experience with Scuba was incredible — the support and professionalism of René, Delfina and captain Larry make you feel safe at every step. I'll definitely be back with them to certify.”
