Wir haben unseren SDI Open Water bei Alan gemacht. Hierfür haben wir vorab den Kontakt über WhatsApp aufgenommen und alles geplant.
Alan hat sich viel Zeit genommen uns alles geduldig zu erklären und uns langsam ans Tauchen heranzuführen. Wir haben uns zu jeder Zeit sicher und wohl gefühlt.
Zusätzlich hat er uns echt gute Empfehlungen für die lokale Küche gegeben!
Danke für diese tollen Erinnerungen, besser gehts nicht!

Tuve la oportunidad de realizar 6 inmersiones con Diving Universe en diferentes cenotes del Yucatán, y la experiencia fue simplemente inolvidable. Cada cenote era único, mágico y lleno de una atmósfera impresionante, y todo estuvo perfectamente organizado de principio a fin. El equipo transmitía siempre seguridad, profesionalidad y pasión por lo que hace.
Un elogio extraordinario a Alan, quien me acompañó en la mayoría de las inmersiones: siempre prudente, paciente, con gran experiencia y una amabilidad que me hizo sentir seguro y cómodo en todo momento. Además, Alan no solo fue un excelente guía bajo el agua, sino que también me ayudó fuera del mundo del buceo, dándome consejos muy útiles sobre la Riviera Maya: dónde comer, qué lugares visitar y cómo aprovechar al máximo mi estancia.
También quiero agradecer profundamente a Brenda, que me guió en una de las jornadas: fue igualmente profesional, atenta y muy simpática. Su manera cercana de explicar y su cuidado constante hicieron que esa inmersión fuera una experiencia muy especial. Además, ella también me ofreció recomendaciones sobre sitios locales, lo cual fue de gran ayuda.
En resumen, Diving Universe es mucho más que un centro de buceo: es una familia que te acompaña, te cuida y hace que vivas la experiencia en los cenotes del Yucatán y en la Riviera Maya de una manera completa, tanto dentro como fuera del agua. Sin duda, lo recomiendo al 100% y volvería sin pensarlo dos veces.

I had the opportunity to do 6 dives with Diving Universe in different cenotes in the Yucatán, and the experience was truly unforgettable. Each cenote was unique, magical, and breathtaking, and everything was perfectly organized from start to finish. The whole team inspired safety, professionalism, and a genuine passion for diving.
A special praise goes to Alan, who guided me through most of the dives: always cautious, patient, highly experienced, and incredibly kind, making me feel safe and comfortable at all times. Beyond being an excellent dive guide, Alan also helped me outside the diving world, giving me great recommendations about the Riviera Maya—where to eat, which places to visit, and how to make the most of my stay.
I also want to sincerely thank Brenda, who guided me on one of the days: she was equally professional, attentive, and very friendly. Her clear explanations and constant care made that dive particularly memorable. She too shared valuable local tips, which I truly appreciated.
In short, Diving Universe is much more than just a dive center: it feels like a family that takes care of you, guides you, and helps you enjoy not only the amazing cenotes of the Yucatán but also the Riviera Maya beyond diving. I absolutely recommend them 100% and would return without hesitation.

We were a group of 6 that did 2 tours. Alan was great to deal with answering all questions before booking through WhatsApp. The first tour was the ocean view of the ruins and snorkeling. Jose was very knowledgeable and took pictures of our group that he shared with us. The second tour was snorkeling in two different cenotes. We had a great time and loved the beauty of both locations! Everyone was super nice and made us feel safe throughout both excursions! Great job!

Vaig tenir una experiència increïble fent submarinisme amb l'Alan al cenote Dos Ojos. Era el meu primer cop en un cenote i estava força nerviosa, però des del primer moment l'Alan em va transmetre molta confiança. És molt professional, atent i té una calma que et fa sentir segura a cada moment. Gràcies a ell vaig poder gaudir de la immersió sense por i descobrir un lloc absolutament màgic. 100% recomanable!

We had the best time with Alan! He was knowledgeable, relaxed, well prepared and just provided an overall amazing experience. We did 4 cenotes dives with him, which were so different from the ocean diving I’d done previously, but thanks to his guidance I felt prepped and relaxed for all of them allowing for maximum enjoyment. 13/10!
