Another thing Bonaire is known for, besides fabulous watersports, birds, donkeys and goats, are their pink salt mines, located in the southeastern part of the island.

Bonaire’s salt is unique because it is naturally produced through solar dehydration using the island’s intense sun, low rainfall, and steady trade winds. They are a distinctive lines of white salt pyramids at the southeastern end of the island. Each pyramid, roughly 50-feet high, contains approximately 10,000 metric tons of 99.6% pure salt. Depending on the time of the year, there can be upwards of 200,000-500,000 metric tons of salt neatly stacked in long rows awaiting shipment. The salt mines, owned and operated by Cargill, occupy about 13% or 16 square miles of the entire island of Bonaire. Bonaire’s salt is exported all over the world in roughly equal portions to Europe, Asia and North America.
The salt of Bonaire is processed through using a natural brining process from the brine lake known as Pekelmeer, which means brine in Dutch.

The unique pink color which is caused by a microorganism called halophilic bacteria, which flourish in high salinity brine and in reality are not bacteria at all but a single cell life-form. The cell membranes contain carotenoid pigments which give the crystallizers the pink-red color. The dark color increases the absorption of sunlight which increases the temperature which in turn increase evaporation and salt production. Eventually it will form an 8 to 10 inch layer of essentially pure salt. The entire process takes 10 to 12 months, depending on the prevailing temperature and wind, as well as the precipitation and the degree to which dust and other contaminants in the air provide the nuclei that spur the crystallization of the salt.

One of the characteristic features of salt produced by solar dehydration is the size of the resulting salt crystals. Unlike “rock salt” from sub-surface mines, or salt obtained from brine solutions created by injecting hot water into underground salt deposits, salt obtained from “natural” processes like solar dehydration produces much larger crystals of salt. Nicknamed “sun gems,” these large crystals are particularly prized for use in water softeners and swimming pools. Bonaire salt finds myriad of other uses, from the dinner table, to a variety of industrial processes, including the production of chlorine gas for water treatment to the more prosaic use to de-ice roads in winter. Every time we go to Bonaire, we bring back some of the Bonaire salt too.

Salt Pier, right across the road from the salt mines, is a favorite dive location on Bonaire as well. It is probably one of the most dived locations on the island. We love diving Salt Pier because it is so full of diverse marine life.



I hope you enjoyed the tour of the salt mines and salt pier. Have a great day and make everyday great. Life is short. Live life to the fullest and enjoy the ride. ‘Til next time.
