Our vision is for the establishment of a regional model of sustainable tourism and development that serves as an example for other similar areas.



El Centro Investigador del Sistema Acuífero (CINDAQ AC) was established in 2000 in order to provide a legitimate mechanism to apply for grants and receive donations for our efforts.  Our primary dive team has more than 70 years of combined experience exploring, mapping and studying the underground rivers of this area.  We have performed over 15,000 dives which translates into tens of thousands of hours of valuable experience and lessons learned both above and below the water.  Our goal is to use our expertise to further the knowledge of the extent of these caves. We do this by incorporating current technology to aid us in locating, mapping and documenting the caves.  With the information that we are able to generate we can help direct and coordinate scientific study of the aquifer and in turn use that information to educate the public at large.
