Salt has been produced in the Cape Verde islands since the 18th Century. Pedra de Lume on the island of Sal (Salt in English) was one of the main areas for production. In 1985 the operations at Pedra de Lume ceased, but the site has become an interesting place for visitors. The remains of the conveyor system, that could transport 25 tons an hour, are still there. Bathing in the water, which is only about 600mm deep is an interesting experience. The salt water makes it easy to float, and the experience is similar to bathing in the Dead Sea. So, when you are able to travel and visit Sal, include Pedra de Lume on your itinerary and take a dip in the water. Take some suitable shoes to use in the pool because of the sharp salt crystals.
