7–8 hours
Light fitness—able to board a small boat, swim short distances, and walk short rocky shore paths.
A seven-and-a-half-hour day cruise from Stintino to Asinara National Park that pairs swimming and snorkeling in protected coves with a shore walk at Cala Reale to meet the island’s famous white donkeys. Expect clear water, local food served aboard, and narration by an environmental guide.
The boat slips away from Port Mannu as the town’s low-slung harbor recedes into blue—fishermen folding nets, a lighthouse watching like an old guard. Sea spray cools your face while the coastline of northwest Sardinia narrows into a silhouette; the skipper hums through the engine and the environmental guide points out the first porpoises arcing beside the bow. The navigation is deliberate: long looks, short swims, a shore stop at Cala Reale where limestone cliffs give way to pale sand and the island’s famously pale donkeys roam with a proprietorial calm.

Meeting point is strict and parking isn’t allowed in the square—plan extra time for drop-off or public transit.
The park enforces conservation rules; avoid chemical sunscreens to protect marine life and coral.
Cala Reale has rocky approaches and uneven paths—non-slip shoes make the short walk comfortable.
Take motion-sickness medication before boarding if you’re sensitive—there are open-water stretches despite sheltered coves.
Asinara served as a quarantine island and later a high-security prison until the late 20th century; it became a national park to protect its unique coastline and ecosystems.
Landing and swimming are restricted to authorized spots to protect fragile habitats; visitors are asked to use reef-safe products and avoid disturbing wildlife.
