The park's most famous residents are its white donkeys, a rare albino variety found almost exclusively on Asinara, giving the island its nickname 'Donkey Island.' The park is also home to wild boars, Sardinian wild horses, and various species of birds including peregrine falcons, Audouin's gulls, and Corsican seabirds. The surrounding waters host rich marine life including dolphins, sperm whales, and various Mediterranean fish species. The island's isolation has helped preserve several endemic species and provides an important stopping point for migratory birds.
Asinara's plant life comprises over 700 species, including several endemic varieties unique to the island and Sardinia. The vegetation is dominated by Mediterranean macchia (shrubland) featuring juniper, mastic, wild olive, and rosemary. The island's northern area hosts rare species like the Centaurea horrida, while coastal areas support specialized salt-tolerant plants. Centuries of grazing have created extensive grasslands, particularly in the central regions. The park's protected status has allowed for the recovery of native vegetation, though some areas still show the impact of historical human activities and grazing.
The island's geological formation dates back to the Paleozoic era, consisting primarily of metamorphic rocks including schist and granite. Asinara's landscape was shaped by tectonic movements that separated it from Sardinia, creating its distinctive elongated form stretching 17.5 kilometers north to south. The coastline alternates between rocky cliffs and small, secluded beaches, while the interior features rolling hills with the highest point being Punta della Scomunica at 408 meters. The eastern coast is characterized by gentler slopes and several natural harbors, while the western coast features more dramatic limestone cliffs.
Asinara's history is as unique as its landscape. Originally inhabited by shepherds and farmers, the island was evacuated in 1885 to establish a quarantine station and penal colony. It served as a prisoner-of-war camp during World War I and later became one of Italy's most important maximum-security prisons, housing many high-profile mafia members until its closure in 1997. The island's isolation during its prison years inadvertently preserved its natural environment, leading to its establishment as a national park in 2002. This unusual history has left the island with numerous historic buildings and structures, including the former prison facilities at Cala d'Oliva and Fornelli.
Key attractions include the historic prison facilities at Cala d'Oliva and Fornelli, which offer insights into the island's unique past. The pristine beaches of Cala Sant'Andrea and Cala dei Detenuti feature crystal-clear waters ideal for swimming and snorkeling. The Working Village at Cala d'Oliva houses the Park's visitor center and museum. The island's network of hiking and cycling trails provides access to scenic viewpoints and historic sites. The marine protected area surrounding the island is popular for diving and boating activities. Visitors should note that access to the island is regulated, and tours must be arranged through authorized operators based in Porto Torres.
Asinara experiences a typical Mediterranean climate with hot, dry summers and mild winters. Summer temperatures typically range from 25-35°C (77-95°F) between June and September, while winter temperatures rarely drop below 10°C (50°F). The island receives most of its rainfall during winter months, particularly from November to February. Strong winds, especially the Mistral from the northwest, are common throughout the year and can affect boat services to the island. The best time to visit is during spring (April-May) and early autumn (September-October) when temperatures are pleasant and tourist crowds are smaller.

Asinara National Park is located on an island off the northwestern tip of Sardinia. The park is known for its unique white donkeys, pristine beaches, and crystal-clear waters. Previously used as a quarantine site and high-security prison, the island was converted to a national park in 1997, preserving its rich biodiversity and historical heritage.
