I went swimming in Cenotes, Yucatan Mexico, and that is the experience I will never forget. You MUST visit Cenotes of Yucatan Mexico when in Cancun!  Read about Cenotes below, but in brief, they are fresh waterpools (actually underground rivers) and a reprieve from the hot Yucatan sun.  Seek them out.  Get information from the web, since getting information locally is hard.  Most taxis, locals, don’t know about all the cenotes, unless you want to go to an established tour (not a bad idea $$).
