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.

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.
