What we do

Mar y Sierra spirit




At Mar y Sierra, we organize dive tours for small groups of divers, providing you with a personalized service. 


The dive guides have extended experience in Cabo Pulmo; they are all PADI Dive Instructor, with EFR training and certified dive guide for the Cabo Pulmo Marine Reserve.


We plan the groups without mixing divers with different levels of certification and/or experience. In high season, we tend to leave early in the morning to be there before other groups. Managing small groups gives us this flexibility, and offers the divers a better quality experience. 




In Cabo Pulmo, you will dive in a protected reserve run by a Mexican Government agency (CONANP).


Rules have been defined by this agency and local dive operators and they have been successfully in place for a few years now. 


Our effort is to lower the impact on this fragile ecosystem and we at Mar y Sierra are very commited in keeping the reefs full of marine life. 



Over the years, many divers have become friends and returning customers.



We enjoy diving so we want to share this feeling in the most relaxed way with you; we take our time to talk with customers and limit the number of customers so we can give you a more personalized service. Our intention is to stay away from big groups of divers, and we hope to continue to communicate our passion this way.
