The CDAA categorises dive sites into three different levels due to their level of technical difficulty when diving. To dive in a site of a particular rating you need to be trained and certified to that level. In addition, some sites require prior experience in other locations of the same rating before access is granted. The three categories are Deep Cavern (includes Cavern and Sinkhole sites), Cave and Advanced Cave.


      Deep Cavern (Cavern/Sinkhole)


      Advanced Cave
