Cave Diving Training in the Cenotes of Mexico

Caverne du Cénote Dos Ojos

The Riviera Maya is one of the world’s most exceptional environments for learning cave diving. The cenotes of the Yucatán offer a remarkable variety of passages, configurations and conditions in which to progressively develop the skills required for cave diving.

Each course combines theory, preparation, technical exercises and dives in a real cave environment. Cenotes and dive routes are selected according to your level, progression and training objectives.

Cenotes • Cavern • Cave Diving • Sidemount • Backmount • Cave Navigation


Cave Diving Training in English, French and Spanish

Cave diving training requires precise communication and a complete understanding of procedures.

Frequently Asked Questions

Which Cave Diving Course Should I Choose?

If you are new to overhead environments, Cavern Diver is the first step. Divers already certified as Cavern Divers can progress to Introductory Cave Diver, followed by Cave Diver to develop more advanced skills and navigation techniques.

Do I Need Previous Technical Diving Experience?

It depends on the course level. Each program has its own prerequisites. Your certifications and diving experience are reviewed before defining the appropriate training pathway.

Can I Take My Cave Diving Course in Sidemount?

Yes. Sidemount is particularly well suited to cave diving in Mexico. However, the configuration used must be appropriate for your experience and the requirements of the selected course.

How Long Does a Cave Diving Course Take?

The duration depends on the course level, your experience and your progression. Certification is not awarded simply because a planned number of training days has been completed: the required skills must be mastered.

Are the Courses Available in English?

Yes. Courses can be taught in English, French or Spanish.

Can I Complete Several Levels During the Same Trip?

Yes, provided your experience, progression and mastery of the required skills allow it. We can build a personalized multi-day training program.

Such an amazing cenote diving day with Halocline Explorers and Julien! 🤿 Two beautiful cenotes, super relaxed vibes, great gear and everything perfectly organized. We even had a nice lunch break between dives, which made the whole day feel easy and unhurried. Great dives, great vibes, great experience — would definitely dive with Julien again! 🤙🏽

J'ai eu le privilège de voir les prestations de Julien Garnier sous différents angles (en tamt que mère qui confie son enfant a un instructeur, en tant que cliente qui fait affaire avec un manager, en tant qu'élève moi-même et aussi en tamt que plongeuse technique confirmée). Julien est d'un professionnalisme exemplaire avec une patience d'ange. Pour ma fille et moi, il a su nous transmettre une parcelle de sa passion pour la plongée. Toujours avec le sourire, même sous l'eau, il enseigne de façon si fluide que même la plongée technique devient simple et la flottabilité un jeu d'enfant. Avec pour première priorité la sécurité de tous, il transmet avec générosité ses connaissances bien au delà des requis d'une formation. Julien, mon ami, merci! Que ce soit pour une première rencontre avec un détendeur ou pour un rêve de devenir plongeur technique, avec Julien Garnier, vous pouvez vous lancer dans l'aventure les yeux fermés (ou avec un couvre masque).

J'ai plongé 2 X avec Julien Garnier aux Bahamas. C'est un excellent moniteur qui vous met en confiance, très patient et attentionné. Avec lui, je n’aurais pas peur de plonger dans des grottes ou endroits improbables, car il est particulièrement expérimenté et responsable. Chantal Lepers, advanced PADI, 141 plongées.

Une super expérience de plongée avec Julien qui m'a ouvert les portes de la plongée technique. Un grand passionné et un très bon technicien qui est, en plus, très sympa! Donc si vous cherchez un très bon instructeur compétent et carré, n'hésitez pas. Moi, j'y retournerai pour me lancer en recycleur! Merci Juju!

Tuve el privilegio de realizar con Halo Explorer (Julien Garnier) tanto mi certificación Open Water como mi certificación Advanced Open Water. A lo largo de toda la formación Julien Garnier ( Divemaster/ Instructor de buceo) demostró un alto nivel de profesionalismo, conocimientos técnicos sólidos y un compromiso constante con la seguridad. Su capacidad para explicar conceptos complejos de manera clara y adaptarse al ritmo de aprendizaje de cada estudiante hizo que la experiencia fuera sumamente enriquecedora y eficaz. Además de su excelencia técnica, destaca por su calma, paciencia y liderazgo bajo el agua, cualidades que inspiran confianza y permiten desarrollar las habilidades necesarias para bucear con seguridad y autonomía. Gracias a su dedicación y calidad de enseñanza, completé ambas certificaciones sintiéndome preparada, segura y motivada para continuar avanzando en el mundo del buceo. Recomiendo los servicios de Halo Explorer sin ninguna reserva a quienes busquen una formación de alta calidad impartida por un instructor y divemaster verdaderamente profesional.
