From the Collier County Museum (http://www.colliermuseums.com/history/index.php): One of the oldest place names on the Gulf coast, it first appeared on a 1771 chart of Florida as Caxymbas Espanolas. Derived from the Arawak Indian word casimba or cacimba, meaning a hole dug along the shore to find drinking water.

Other interesting facts about Caxambas:
It is the highest point in Southwest Florida at 52 feet
Here are the ruins of the Pineapple Plantation house built in 1877
