The Oristano area—and particularly the Sinis Peninsula, with its rich network of waterways, lagoons and ponds—presents great biodiversity.

A wide range of vantage points offer the following birdwatching possibilities: flamingos, various heron species, egrets, terns, avocets, curlews, shelducks, sandpipers, pipits, stilts, wagtails, bee-eaters, quail, warblers and peregrine falcons, to name but a few.
