Definitely worth a visit. We visited another grotto during our stay, but this one was considerably larger and more impressive.

Salt is extracted from shallow, concrete or stone pans of varying sizes, where saltwater drawn from a well is conveyed through ditches. Currently, the water is pumped by a motor and distributed according to a system that is generally accepted and respected (not always) by all the owners. Drainpipes, threshing floors, and wooden salt storage houses complete the complex known as the Rio Maior Salt Pans. According to technicians, a large and deep rock salt mine, traversed by an underground stream that feeds a well, makes the extracted water salty, seven times saltier than seawater. The salt is obtained from its exposure to the sun and wind, and the resulting evaporation of the water. This salt is deposited at the bottom of the pans, which are then piled up in pyramid-shaped heaps to dry until harvest. The process is rudimentary and similar to that used in seaside salt mines. The only difference is the picturesque valley that surrounds them, the well, the unique style of the sailors (as the men who work in the salt mines are known), the wooden houses and the country air that you breathe.

Just three kilometres from Rio Maior, on the southern tip of the Serra dos Candeeiros, lie the only inland salt pans in Portugal, and the only ones still active in the whole of Europe. Surrounded by vineyards and cultivated fields, they are a true wonder of nature, as the sea is 30 kilometres away. Their history dates back to at least 1177, but it is said that rock salt has been mined since prehistoric times. The water, seven times saltier than that of the ocean, emerges from a well after passing through an underground deposit, leaving behind the pure vestige of an ancient sea.

The Rio Maior Salt Pans are located about 3 km from the city centre and are nestled in a valley at the foot of the Serra dos Candeeiros, in the heart of the Serras de Aire e Candeeiros Natural Park. Classified as a Property of Public Interest since December 1997, these are the only inland salt pans in Portugal, and the only ones in full operation in Europe. The first reference to their existence dates back to 1177, but it is thought that the use of rock salt was already being made in prehistoric times.

Surrounded by vineyards and farmland, they are considered a natural wonder, as the ocean is 30 km away. The salt is a vestige of the sea's presence in ancient times.
