Top 15 Natural Monuments around Caldas Da Rainha

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.

The Pena da Gouvinha fountain used to serve the locals. There was a queue to fill the bottles, so much so that it was decided that each resident could only take eight bottles of water and would have to “give others a chance”. Today it serves as a stopping point to cool off during the walk and, if you wish, you can take advantage of the place to eat whatever you have prepared at home. There is a picnic area next to the fountain. The place name Pena da Gouvinha suggests that barbarians passed through here. Gouvinha is a personal name of Germanic origin, still documented in the 12th century as Gaudina.

Salir do Porto has a river beach, on the bank of the Tornada River, which flows into the bay of São Martinho do Porto. Salir beach is famous for its sand dune about 50 meters high. Once the largest in Europe, the Salir Dune stands out in the dune landscape of São Martinho Bay. The core of the Dune is partly made up of red sandstone, a vestige of an older dune – a fossil dune. There are other rock beaches in the coastal area that are locally called Quebradas. It was in the Ruins of the artisanal Customs House of Salir that the caravels that participated in the discoveries and conquests were built during the reigns of D. Afonso V and D. João II. The extinct parish was made up of the towns of Salir do Porto, Casais de Salir do Porto and Bouro.

Climbing up the sand dune and sliding down from the top is the highlight for everyone

Be sure to go up there from the top, great view and slide down on your bum. Large dune that clings to the rocks there, perfect for hiking. At the foot of the dune, the Tornada river flows into the sea.
