Asinara boat tours from Stintino, and what to do once you land

Asinara, the island off Stintino’s north-western tip, spent most of the 20th century as a high-security prison and quarantine station, which is exactly why it’s now one of Sardinia’s best-preserved natural spaces — decades with almost no development left the island’s coves, cliffs and famous albino donkeys largely undisturbed. There’s no free-roaming car access; nearly every visitor arrives by boat tour, and this guide covers the main options plus what to do once you’re actually on the island.

Where	Island national park off Stintino, north-west Sardinia
Cost	Half-day tour roughly €40-60pp; full-day catamaran tours €60-90pp
Time needed	Full day for a proper visit; half-day covers the closer bays only
Getting there	Boat from Stintino or Porto Torres — no public car ferry
Best time	June to September for swimming; the park itself is open year-round

The wildlife you might actually see

Asinara’s isolation preserved more than architecture — the island’s population of white donkeys, a genuinely distinct breed with a form of albinism rare enough to have made them something of a symbol for the whole national park, graze freely across the island’s grassland areas. Wild horses, mouflon sheep introduced decades ago, and a healthy population of peregrine falcons and other birds of prey round out the wildlife most guided tours mention, though as with any wild population, sightings vary by season and time of day rather than being scripted into the itinerary.

Why the crossing point matters

Stintino sits at the closest mainland point to Asinara, which is why nearly every operator on this page departs from there rather than further afield — the shorter crossing means more time actually on or around the island rather than travelling to reach it. Porto Torres, further east, has its own departures too, generally used by visitors already staying in that town or arriving by ferry from the Italian mainland, since Porto Torres is one of northern Sardinia’s main ferry ports. Either departure point reaches the same island, so the choice mostly comes down to where you’re already staying rather than any meaningful difference in what the trip covers.

Full-day catamaran: the most complete way to see the island

A full-day catamaran tour is the standard way to see Asinara properly — the crossing from Stintino, a guided route around several of the island’s bays, and typically a swim and lunch stop at Cala Sabina or Cala d’Arena, two of the clearer-water coves on the island’s more sheltered side:

For a version with lunch built more centrally into the day, and time to properly relax at anchor rather than keep moving between stops, a catamaran tour combining the crossing with an onboard meal is worth the modest premium:

Faster and smaller: RIB and speedboat options

For a faster, more manoeuvrable crossing that reaches smaller coves the larger catamarans skip, a RIB tour into the gulf around Asinara trades some comfort for access and a shorter overall trip time — useful if you only have a half-day rather than a full one:

A speedboat version covers similar ground with a sportier ride, a reasonable choice for anyone who wants the destination without the longer, steadier crossing of a full-day catamaran.

Vintage sailing: a slower, more atmospheric crossing

For a genuinely different pace, a handful of operators run the Asinara route on a restored vintage sailing boat rather than a motor launch, with lunch included and a noticeably calmer, quieter crossing when conditions allow:

Comparing the main boat options

Trip type	Typical price	Duration	Best for
Full-day catamaran	€60-90pp	7-8 hours	First visits, complete island coverage
Half-day RIB/speedboat	€40-60pp	4-5 hours	Tighter schedules, closer bays
Vintage sailing with lunch	€65-95pp	6-7 hours	A slower, more atmospheric day
Sunset sailing with La Pelosa	€45-70pp	3-4 hours	Combining two highlights in one evening

The full-day catamaran remains the default choice for good reason: Asinara is genuinely large, at around 18km end to end, and a shorter trip only reaches the closer southern bays near the old prison settlements, missing the lighthouse at Punta Scorno and the areas further north where donkey sightings are most reliable.

Combining Asinara with La Pelosa

Since La Pelosa sits directly across the strait from Asinara’s southern tip, several operators combine both on the same outing — a sunset sailing tour that takes in the island’s silhouette alongside Stintino’s own famous beach is a popular way to see both without committing a full day to each separately. Full detail on La Pelosa’s own access quota, which applies regardless of how you reach it, is in Sardinia’s beach access quotas.

A brief history of Asinara

Asinara’s isolation wasn’t always a natural-park choice — from 1885 the island housed a quarantine station for arriving ships, and from 1885 to 1997 a maximum-security prison that at various points held some of Italy’s most notorious mafia and terrorism-related inmates, kept under a strict isolation regime that shaped the whole island’s development, or lack of it.

The prison finally closed in 1997, and Asinara became a national park the same year, which is why the island still has intact prison blocks, a former agricultural penal colony, and almost none of the tourist infrastructure that developed elsewhere in Sardinia during the 20th century. That history is part of what most guided minivan tours cover, alongside the island’s natural side, and it’s worth knowing before you go if the buildings themselves seem unexpectedly grim for what’s marketed as a nature day out.

Getting around once you’re on the island

Asinara’s national park status means private cars are essentially barred, and most boat tours include a guided minivan route around the island’s key sites — the former prison buildings, the lighthouse at Punta Scorno, and the areas where the island’s white donkeys are most often seen grazing:

For a more active alternative, mountain bikes can be rented from Porto Torres for those who’d rather cover the island’s tracks under their own power, and guided kayaking excursions from the same town explore the coastline at water level for a different pace again than a standard boat tour. Both work well as a follow-up to a first, boat-tour-based visit rather than a first introduction to the island. Full detail on the park’s rules and history is in Asinara National Park guide.

What to pack for an Asinara day trip

Sturdy shoes matter more here than on a standard beach day — the guided minivan stops usually involve some walking over uneven ground around the former prison buildings and viewpoints, not just time on sand. Reef-safe sunscreen and a hat are essential given the limited shade on most of the island’s open areas, and a water bottle is worth bringing even though most operators provide some water during the day, since it’s a long day with real physical activity built in. Binoculars are genuinely useful if the wildlife — not just the donkeys but also the birdlife, including peregrine falcons nesting on the cliffs — is part of the appeal.

Money-saving tips for an Asinara trip

The half-day RIB or speedboat options cost less than the full-day catamaran and still reach a meaningful stretch of the island’s southern coves, a reasonable compromise if budget or time is tight. Shoulder-season prices (May, June, September) generally undercut the July-August peak, and booking directly rather than through a hotel concierge sometimes saves a modest amount, though it’s worth comparing the specific itinerary rather than price alone, since cheaper trips sometimes cover less ground. See Sardinia on a budget for how an Asinara day fits into a broader cost-conscious trip to the north-west.

When to go

June to September gives the warmest water for the swim stops most tours include; outside that window, fewer boats run and some land-based tours reduce frequency. The island’s donkeys and birdlife are visible year-round, so a cooler-season visit still has appeal if swimming isn’t the priority. See Sardinia’s wildlife: what you can see for more on the island’s animals.

Where to base yourself

Stintino is the obvious base — every major operator departs from its marina, and it puts you a short drive from La Pelosa for the same trip. Porto Torres, a larger town with its own ferry connections, works as an alternative base with slightly fewer but still regular Asinara departures. Both are within reach of Alghero-Fertilia airport and Sassari.

A realistic day plan

Boats to Asinara typically depart Stintino by mid-morning, giving the crossing and the first stop the calmest water of the day before any afternoon breeze picks up. A full-day itinerary generally covers two or three landing points spread across the island’s south and centre, with a lunch stop — either on board or at a designated spot on the island — breaking up the day. Returning to Stintino by late afternoon leaves time for a shower and an early dinner, though it’s a genuinely full day rather than a relaxed half-day outing, worth factoring into the rest of your schedule if Asinara is one of several activities planned for the same trip.

Weather and sea conditions

The strait between Stintino and Asinara is more exposed than a sheltered bay, and can develop a noticeable chop when the mistral picks up, more common in spring and autumn than in the settled summer months. Most operators either shorten the route to calmer, more sheltered stops or cancel outright and rebook on a rough-sea day; check the specific cancellation policy before paying in shoulder season, when conditions are less predictable than July or August.

Combining Asinara with the rest of north-west Sardinia

Stintino and Porto Torres sit within easy reach of Alghero and Sassari, which makes a north-west itinerary spanning Asinara, La Pelosa, Alghero’s boat trips to Capo Caccia, and Castelsardo’s old town a genuinely well-rounded few days without excessive driving. See Alghero-Fertilia airport guide for how this corner of the island connects by air, and Sardinia in September for why that specific month suits this region particularly well — settled weather, warm water, and noticeably fewer boats queuing at the Asinara crossing than in August.

Booking tips specific to Asinara

Because access to the island runs almost entirely through organised tours, comparing operators means comparing itineraries more than comparing a generic “boat trip” product — check specifically whether the price includes the minivan land tour or charges it separately, whether lunch is provided or you should bring your own, and how many total stops the route covers. A tour that markets itself primarily on the crossing and a single beach stop will show you less of the island’s history and wildlife than one that builds in the guided land component from the start.

Frequently asked questions about Asinara boat tours

Can I drive my own car onto Asinara?

No — the island is a national park with no public car ferry; visitors arrive by boat tour and get around via guided minivan, bike or on foot.

How long does the crossing to Asinara take?

Roughly 30-45 minutes each way from Stintino, depending on the boat and sea conditions.

Is Asinara worth visiting if I’ve already seen La Pelosa?

Yes — they’re different experiences. La Pelosa is a beach day; Asinara is a half-day-to-full-day island visit combining history, wildlife and a handful of quieter coves.

Will I definitely see the white donkeys?

Sightings are common but not guaranteed — the donkeys graze freely across the island and tours can’t promise an encounter, though most guided minivan routes pass through areas where they’re regularly spotted.

Do I need to book in advance?

In July and August, yes, a few days ahead for the more popular full-day catamaran departures. In shoulder season, a day or two’s notice is usually enough.

Is a half-day or full-day Asinara tour better for families?

A half-day RIB or catamaran suits younger children better, since it’s shorter and involves less time on the water overall; older children and adults get more out of the full island coverage a full-day trip provides.

Why was Asinara closed to the public for so long?

It housed a maximum-security prison until 1997, alongside a 19th-century quarantine station before that — over a century of restricted access that, somewhat accidentally, preserved the island’s coves and wildlife from the development seen elsewhere in Sardinia.

Can I dive or snorkel independently around Asinara?

The marine protected area around the island has specific rules on where independent snorkelling and diving are permitted; most visitors snorkel during the swim stops included in a standard boat tour rather than arranging independent access, which is more restricted here than on the open coast.

Is Asinara suitable for a day trip if I only have one full day in Stintino?

Yes, but it will take most of that day given the crossing time and the island’s size — if a full Asinara day and a proper La Pelosa beach day both matter to you, plan on at least two full days in the area rather than trying to combine them into one.

How does Asinara compare with Tavolara or La Maddalena as an island day trip?

Asinara is the most structured of the three, since nearly all access runs through guided tours given the national park’s restrictions; Tavolara and La Maddalena allow more independent exploration once you’re on the water, with Tavolara focused on a single beach and La Maddalena spread across several islands.
