The Castro Marim Salt Pans, located in the Castro Marim and Vila Real de Santo António Salt Marsh Nature Reserve, are a historical and ecological landmark of the Algarve, where the artisanal production of salt and fleur de sel remains alive. 👍

An important natural product is extracted from the sea's saltwater here. Only through the power of the elements, sun and wind, which evaporate the water in the saltworks' shallow basins, does pure salt remain. Even today, you won't find a kitchen without salt to season dishes. But in earlier times, it had an additional significance: It was important for preserving food—making it so precious that salt was called "white gold."

Parque Natural da Ria Farmosa You can walk for miles along the beach from Tavira to Fábricia. From there you can take a small boat to the town for €1.50. The beach is almost deserted for early June. Small and large shells line the path, in my opinion one of the most beautiful beaches in Europe.

Our holiday in Golden Club in Cabanas was still quiet and not too busy for the end of May. The transfer to the beach was free for hotel guests. The kilometer-long beach was practically deserted and the waves were not that strong. Unfortunately, there were no umbrellas on the beach.

Salt mountains spread across the landscape - which could be mistaken for snow if we weren't in the Algarve. The entire area is part of an environmental protection area that has several species of birds, such as Flamingos.
