Zero Classroom Stress

Real Experience

The Advanced Adventure course is designed to introduce you to five different diving specialties under the direct guidance of your instructor.

Let's Unlock the Next Level of the Ocean Together

Once you have your Open Water ticket, the ocean changes. You start looking at deeper reefs, shipwrecks, or unique deep cenotes and thinking: 'I want to go there.'
The Advanced course isn't about being 'macho' or rushing into danger. It's about learning the subtle skills—compass work, breathing rhythms, and deeper safety margins—that turn a good diver into an exceptional, independent one.

I will be right next to you, step by step, sharing everything I've learned over the years. Let's make you the calmest, safest diver in the group.

 Trustindex verifies that the original source of the review is Google. My family and I were able to take a boat out to snorkel and see the ruins. We snorkeled with sea turtles, a sting ray, a puffer fish and other small fish. We were able to get away from the other group of people and snorkel at a reef. They knew what they were doing, it was great being a private group going out.

 Trustindex verifies that the original source of the review is Google. Would highly recommend.  We swam in the cenote close to our place was beautiful and easy for the kids to swim around in.  We combined with some fishing snorkling another day.  They were able to pick us up at Airbnb we were staying right across the bay from them. Oswaldo was on time and friendly. We caught some great fish, couple good sized barracuda.  The guys cleaned and prepped them.  Even got good pictures with the kids and the catch.  We have three small kids and all managed well.  We stopped off and did some snorkeling in an amazing reef with the kids and even swam with some turtles. Oswaldo in particular has great English.  I speak some very little Spanish and we were able to communicate easily.

 Trustindex verifies that the original source of the review is Google. Si van a Casa Cenote, definitivamente tienen que buscar a Oswaldo. He hecho varias actividades con él a lo largo del tiempo y siempre ha sido una experiencia increíble.

Hemos hecho snorkel en Casa Cenote, recorrido en kayak para conocer la zona y ver al famoso cocodrilo, buceo y también varias salidas de pesca, tanto de troleo como pesca con arpón. Oswaldo conoce perfectamente la zona y el agua, y siempre hace que cada salida sea diferente y especial.

Lo mejor de todo es su atención. Es súper profesional, amable, paciente y siempre está pendiente de la seguridad y de que realmente disfrutes la experiencia. No importa si eres principiante o ya tienes experiencia: se adapta perfectamente a cada persona y nunca sientes que estás haciendo un tour turístico genérico.

Además, habla excelente inglés, tiene muy buena actitud y realmente se nota la pasión que tiene por el mar y por su trabajo.

Para mí ya es una persona de confianza cada vez que quiero hacer alguna actividad en el agua por la zona. Si están en Tulum y quieren conocer Casa Cenote de una manera auténtica y con alguien que realmente sabe lo que hace, Oswaldo es la persona indicada.

Servicio de 10/10. Lo recomiendo completamente y definitivamente seguiré regresando con él.

P.D. Y un detalle que hace todavía mejor la experiencia: en varias de nuestras salidas de pesca hemos terminado preparando juntos un ceviche o algún plato con el pescado que logramos capturar ese mismo día. Es una excelente manera de cerrar la jornada y hace que toda la experiencia se sienta todavía más auténtica y especial.
