A stone's throw from the city, the Park is one of the most important examples of ecosystem in Europe. Established in 1999, it covers an area of over 1,600 hectares in which numerous animal species have found their ideal habitat. There are so many routes, and all of them are impressive and interesting winding through this wetland. You can travel freely on foot or by bike, or you can choose to follow the guided birdwatching route for example. They all allow you to observe the birdlife, explore the secrets of the pond and get to know its exceptional inhabitants up close: pink flamingoes, marsh harriers, egrets, avocets, sultan chickens and many other species. A trip is recommended both in spring, for the flamingo nesting, and in autumn, when thousands of passing species gather together in the various ponds, which have different degrees of salinity: the Bellarosa Minore and the Perdalonga are freshwater, while the Bellarosa Maggiore or Molentàrgius and the Quartu pond are the first evaporation basins of the former state salt pans. The park protects the de facto integrity of the salt pans, even though production has ceased, precisely to preserve an extremely varied environment, thus guaranteeing the biodiversity of the wetland.
