The best boat tour in Sardinia, coastline by coastline

Ask five people who have done a Sardinia boat trip which one to book and you will get five different answers, and all of them will be at least partly right, because the island doesn’t have one great boat coastline — it has four genuinely different ones, and the best choice depends on what kind of day at sea you actually want. A Gulf of Orosei trip out of Cala Gonone is not the same experience as an archipelago hop around La Maddalena, and neither is much like a lazy sunset run off the Costa Smeralda.

This is a comparison, not a single recommendation, because the honest answer changes depending on where you’re based and what you want to see. If you only have time for one boat day in a week on the island, read the coastline breakdowns below before you book, because picking the wrong one for your priorities is the most common regret we hear about.

Most dramatic scenery	Gulf of Orosei, from Cala Gonone or Santa Maria Navarrese
Best for island-hopping	La Maddalena archipelago, from Palau or Cannigione
Most relaxed, shortest transfer	Costa Smeralda, from Olbia or Porto Rotondo
Best value near a city base	Cagliari gulf, from the capital itself
Typical cost	€45-75 for a shared half-day tour; €120-250+ for a private full-day charter

The Gulf of Orosei: the scenery-first choice

If the point of a boat day is jaw-dropping coastline rather than convenience, the Gulf of Orosei wins without much argument. This is the roadless stretch of limestone cliff between Cala Gonone and Santa Maria Navarrese, reachable only by boat or a serious hike, and it includes Cala Luna, Cala Mariolu and Cala Goloritzè — three of the most photographed beaches on the island, each with a different character, all with restricted daily access that a boat tour sidesteps entirely.

From the southern end, tours from Arbatax cover the same coastline from the opposite direction, useful if you’re based in Ogliastra rather than the Dorgali side:

The trade-off is distance from anywhere else — driving times in Sardinia run long, and this coast sits well away from the main airports, so it usually means basing yourself on the east coast for a few days rather than a quick detour.

La Maddalena archipelago: the island-hopping choice

Seven main islands and a scattering of granite islets, protected as a national park, with genuinely turquoise water even by Sardinian standards — the La Maddalena archipelago rewards a full day far more than a half-day, because most tours pack in three or four separate swim stops across different islands rather than one long coastal run.

This coast also works as the launch point for a Corsica add-on, since Bonifacio and the Lavezzi Islands sit a short crossing further north — worth building into an itinerary if you’re basing yourself around Santa Teresa Gallura or Palau for a few days rather than passing through once.

Costa Smeralda: the low-effort choice

If your priority is a relaxed day rather than ticking off the most dramatic scenery, the sheltered water and short transfer times around Porto Rotondo and Porto Cervo make the Costa Smeralda the easiest boat day to slot into a beach-based holiday without an early start or a long drive first. It’s calmer water generally, which also matters if anyone in your group gets seasick.

Cagliari: the city-base choice

Basing yourself in Cagliari for city sightseeing doesn’t mean giving up on a decent boat day — the gulf around the Sella del Diavolo headland has clear water and accessible swim stops within a short run of the marina, making it the most convenient option if you don’t want to burn half a driving day just reaching the boat.

It won’t out-dazzle the Gulf of Orosei on scenery, but for a one-base trip built around things to do in Cagliari it’s a genuinely good use of a spare morning.

Shared group tours versus private charters

Most boat tours run as shared trips on a fixed schedule, seating anywhere from a dozen to fifty passengers depending on the boat, and cost noticeably less per person as a result. Private charters, whether a small rib or a larger catamaran, let you set your own stops and timing and suit families or groups who’d rather not share swim time with strangers — see private versus group boat tours for a fuller breakdown of when each makes sense.

What none of these tours tell you upfront

Weather cancellations happen more often on exposed coasts like the Gulf of Orosei than sheltered ones like the Costa Smeralda, and refund policies vary between operators — always check the cancellation terms before paying in full. For a wider look at the industry’s less flattering habits, what boat tour operators don’t tell you covers commission-driven stop selection and inflated “exclusive cove” claims worth knowing about before you book.

Frequently asked questions about choosing a Sardinia boat tour

Which Sardinia boat tour has the best scenery?

The Gulf of Orosei, run from Cala Gonone or Santa Maria Navarrese, is generally considered the most dramatic, combining limestone cliffs with Cala Luna, Cala Mariolu and Cala Goloritzè on one route.

Is La Maddalena or the Gulf of Orosei better for swimming?

La Maddalena generally has calmer, more sheltered water suited to longer swim stops, while the Gulf of Orosei’s coves are stunning but occasionally choppier given their exposure to the open sea.

Do I need to book a boat tour in advance in August?

Yes — popular routes on the Gulf of Orosei and La Maddalena regularly sell out days ahead in July and August, so booking at least a week ahead is sensible during peak season.

Can I do more than one boat tour in a week on the island?

Yes, and many visitors do, since the coastlines are different enough to justify it — pairing a Gulf of Orosei day with a La Maddalena day, for instance, covers two distinct kinds of Sardinian coastline in one trip.

Are boat tours suitable for people who get seasick?

Sheltered routes like the Costa Smeralda and the Cagliari gulf are the calmest options; the open-water crossings on Gulf of Orosei and some La Maddalena routes can get choppier on a windy day.

What happens if a boat tour is cancelled for weather?

Most reputable operators offer a full refund or reschedule for weather cancellations, but policies vary — check the specific operator’s terms before booking, especially for a non-refundable rate.

Building a boat day into a wider itinerary

If a boat trip is the centrepiece of your visit rather than a single afternoon, it’s worth planning the rest of the trip around it — the seven-day east coast itinerary is built specifically around Gulf of Orosei access, while a north Sardinia week puts La Maddalena and the Costa Smeralda within easy reach on consecutive days.
