Outline of recreational dive sites
Reef dive sites. In the context of recreational diving, a reef may be a coral reef or a bottom of predominantly consolidated inorganic material, like rocky reef, and in the broader sense includes artificial structures and even ships sunk as artificial reefs. Reef diving regions are geographical regions of arbitrary size known for including more than one named reef dive site, while a reef dive site is a specific part of a reef known by a name, which recreational divers visit to dive. Cave dive sites. Many cave dive sites are fresh water, but there  are some that are sea water and a few that are partly fresh and partly sea water, and these may have a distinct halocline.
