Molentargius Saline Nature Park includes the ancient salt mines (saline), whose use is certified by documents dating back to the Roman period, and the Molentargius pond itself, with its protected wildlife. Home to flamingoes and other species of residential and migratory birds, the park is ideally placed between Urpinu Hill and Poetto Beach, giving visitors the possibility to trek, run or cycle. There are also spots for bird watching.
