Asinara is a long, rugged island off the north-west tip of Sardinia, and for more than a century it was a penal colony and quarantine station. Public access was closed until the 1990s, which protected the landscape and left it wilder than almost anywhere else on the island. Today it is a national park, with scrub-covered hills, sheer cliffs, quiet bays and a population of wild white donkeys that have become its emblem. Mouflon, wild boar and peregrine falcons also live here, and the sea around it is part of a marine reserve. Boat tours depart from Stintino, Porto Torres and nearby ports and combine a cruise along the island's coast with stops to swim and time ashore. A lunch on board is common, usually built around local fish. Because motor traffic on the island is limited, the beaches and lanes feel remote, and the water is among the clearest in the north.
What you see
Cliffs and coves along the island's west side, the old prison buildings at Cala d'Oliva and Fornelli, and beaches such as Cala Sabina and Cala Arena. White donkeys may appear at the roadside or on a hillside, though sightings are not guaranteed. On the water you may spot gulls, shearwaters and, with luck, dolphins. The mix of history and nature gives the island an atmosphere unlike anywhere else on Sardinia.
Choosing how to do it
A boat tour with lunch is the simplest and gives swimming time. Others offer jeep or minivan tours inside the park, which see more of the interior but less of the coast. If you have two days, you can combine both types. The island has no large hotels, and visitor numbers are controlled, so expect a peaceful day.
When to go
The season runs from late spring to early autumn, with the best swimming in June to September. The sun is strong and shade is limited, so bring a hat, sun cream, water and a light cover-up. A towel, swimwear and a bag with a change of clothes are useful. Services on the island are minimal, so carry what you need. Trips depend on sea conditions, and the mistral can cancel crossings at short notice, so check the cancellation terms when you book.
Practical notes
Asinara is a protected area with its own rules, and numbers are limited, so places on boats and tours can fill in summer. The island's history is part of the appeal. It served as a prison and quarantine station, and old buildings still stand at Cala d'Oliva, Fornelli and Cala Reale. The park has little shade and almost no shops, so a hat, water and a snack matter, and mobile coverage can be patchy.
Tours from Stintino pass the famous white beach of La Pelosa and the old Aragonese tower, which is worth a photograph from the water. If you have a second day, the Stintino peninsula has more beaches and a small tuna-fishing heritage. Take a jacket for the crossing, as wind on the strait can be strong even on hot days.
