Asinara has been isolated for a very long time so despite its proximity to Sardinia and Corsica it has various unique flora and fauna. Of these by far the biggest are the albino donkeys.
Now, when you see the tourist photos these are white, fluffy and cute. In real life, they are grey, grubby and bored rigid with being cooed at by tourists in a wide range of European languages. They can probably determine the make of your camera by the shutter click alone. This donkey graciously allowed herself to be petted, but the curled lip and cross ears showed her preference for an undisturbed siesta.
The unique sound of Asinara, amidst the ubiquitous cicadas and screaming gulls, is braying donkeys, calling to each other across the gently rolling scrub at dawn and dusk.
