This place is a good example of how conservation can be overdone. Driving along the dam allows you to get closer to the flamingos than walking or cycling through the so-called park. I was disappointed. It's better to go to the zoo to see the flamingos.

Pack your bike and get ready for a tour through one of Sardinia's most breathtaking nature reserves: the Molentargius-Saline Regional Natural Park. Introduced by Regional Law No. 5 of February 26, 1999, this green paradise extends over the territory of the municipalities of Cagliari and Quartu, right at the gates of the picturesque Poetto beach. Grab your helmet and get started: This park is made for cycling enthusiasts like you. The paths are car-free and offer easy, pleasant cycling. The fresh wind blows around your nose as you drive through an impressive landscape that is bursting with life. Birds chirp, grass rustles and then, as if out of nowhere, they appear - thousands of flamingos standing majestically in the shallow water. A sight that you won't soon forget. Your path continues, always along the picturesque coast, until you make a stop by the sea. Feel the sand between your toes, listen to the waves and breathe in the salty sea breeze. Wonderful, isn't it? The journey ends, but only for now, at the port of Cagliari. You can park your bike here and end the day in one of the cozy cafés. But don't worry, Molentargius Park in Quartu is already waiting for your next visit. A place to which you always enjoy returning - by bike, of course.

This section of the MTB tour leads to Molentargius Park, a unique nature reserve. Where there were salt basins for centuries, the pink flamingo now has its home and can be admired there undisturbed. The Molentargius Saltworks has a large extension from the foothills of the Campidano, which I travel on another tour, to the districts of Quartu Sant'Elena, Quartucciu and Selargius as well as to the south of the long Poetto sea promenade, all of which are on this tour. The cycle paths in the nature park are easily accessible gravel roads or paths and are well signposted. Otherwise, you ride on paved bike paths and less often on roads with cars. The cycle paths in the nature reserve are directly connected to the Via Sale cycle path, which leads out of the city of Cagliari, and enable a largely relaxed cycle tour along the entire route. The Terramaini cycle path to Selargius or Monserrato is only accessible via a short stretch of city road.

The Parco offers car-free, easy cycling and a variety of fauna and flora. 1000 de flamingos to admire, a stop by the sea. Wonderful.

The primary natural areas are the Molentargius–Saline Regional Natural Park and the Stagno di Santa Gilla (also known as Stagno di Cagliari). Both are internationally recognized wetlands, crucial for their ecological importance and diverse birdlife, including pink flamingos.
Pink flamingos are a major attraction at both the Molentargius-Saline Regional Park and the Stagno di Santa Gilla. They have been nesting in these areas since the early 1990s, particularly in the Bellarosa Maggiore area of Molentargius. Early June is an excellent time to witness them. You can specifically visit the Molentargius Salt Pans and Flamingos for a great viewing experience.
Yes, the Molentargius–Saline Regional Natural Park offers car-free and pleasant cycling paths. There's also a Cycling and Walking Path of Molentargius Park that immerses you in the beautiful park. For more cycling options, check out the Cycling around Casteddu/Cagliari guide, which includes routes like 'In the Molentargius-Saline Regional Natural Park - ring tour'.
The Molentargius-Saline Regional Park is a haven for bird enthusiasts, hosting around 230 bird species, including cormorants, great egrets, purple herons, avocets, and black-winged stilts, in addition to flamingos. The Stagno di Santa Gilla is also a primary European migration and nesting site for greater flamingos and nearly 200 other bird species. Observation huts and platforms are available in both areas.
Yes, areas like the Molentargius–Saline Regional Natural Park and the Molentargius Salt Pans and Flamingos are considered family-friendly. The car-free paths in Molentargius are suitable for easy cycling and walking with children.
While flamingos can be seen throughout the year, early June is particularly good for witnessing them bathing in the lagoons. The wet seasons are generally better for observing a wider variety of lake fauna, as some ponds like Stagno di Stani Saliu are dry in summer but populated by birds during wetter periods.
Yes, both the Molentargius-Saline Regional Park and the Stagno di Santa Gilla offer well-marked paths for walking. The Cycling and Walking Path of Molentargius Park is a great option for pedestrians. You can find more walking routes in the Hiking around Casteddu/Cagliari guide.
The Molentargius-Saline Regional Park is unique for its coexistence of both freshwater (like Bellarosa Minore and Perdalonga) and saltwater environments (like Bellarosa Maggiore and the Saline), separated by a strip of land. This blend creates a rich and diverse habitat, making it one of Europe's most important wetlands, especially for its large flamingo population and historical salt production.
Yes, the Stagno di Santa Gilla has significant historical importance. It was the site of the first Carthaginian Carales trade and fishing center in the 8th century BC and later served as the capital of the Giudicate of Calari in the Middle Ages. The Molentargius area also has a millennia-long history of salt extraction, where donkeys (molentargius in Sardinian) transported the salt.
While Molentargius and Santa Gilla are prominent, the Stagno di Stani Saliu is a salty pond that, while dry in summer, becomes populated by flamingos and other lake fauna during wet seasons, offering a notable spot for bike rides and observation.
Yes, within the Molentargius-Saline Regional Park, there are observation huts and platforms for optimal bird viewing. The Flamingo Pool is a specific stretch of road crossing the salt pans, offering opportunities to spot pink flamingos up close. Along the S.S. 195 road near Stagno di Santa Gilla, there are also dedicated birdwatching points and observation paths.
