Alghero faces west into open sea, and there is nothing between this coast and the Balearic Islands.
That single fact decides what boat trips here are like. This is not the cave-hopping of the Amalfi Coast or the island circuit of Capri. It is sailing: catamarans and sailboats out of the harbour, a sheltered bay to work in, cliffs to sit under, and a sunset that goes down into water rather than behind a headland.
Almost half of everything bookable in Alghero happens on a boat. That is unusual, and it tells you where the town’s pleasure actually is.
What the coast gives you
Two things, in opposite directions.
North west, the cape. The coast runs out to Capo Caccia, where a two hundred metre limestone wall drops straight into the sea. Boats run along the base of it, past cave mouths at water level and the little island of Foradada with a hole punched through it. This is the dramatic half.
Inside, Porto Conte. A deep bay behind the cape, a marine protected area, and the calmest water on this coast. Almost all the swimming and snorkelling stops happen here, because outside the cape the swell arrives from a very long way away with nothing to slow it down.
Most half-day trips do some of both.
Which trip to take
A half-day catamaran with an aperitif. The standard, and the one most people want. Three hours or so, out to Porto Conte, a swim stop, something to drink on the way back. Catamarans are the right boat here because they are flat, stable and you can lie on the netting at the front. The Porto Conte half-day is rated 4.8 from well over three hundred people, which for a town this size is a lot of agreement.
A full day under sail with lunch. Longer, quieter, further along the coast, and lunch on board. This is the one to take if you have four days here and want one of them to be entirely about the water. Two different operators run versions of it.
A sunset sail. The one I would book if I booked only one. Two to three hours, out in the late afternoon, drinks aboard, and the light going down into open water on the way back. There is also an adults-only version if you would rather not share it with a school party.
A mini yacht with snorkelling. Smaller boat, smaller group, more time actually in the water. Rated 4.9 from four hundred people, which is the highest agreement on any trip here. Take this one if the swimming matters more than the sailing.
Snorkelling, and what is down there
Porto Conte is protected water and it shows. Expect seagrass meadows, which are dull to look at and are the reason everything else is there, plus bream, wrasse, octopus in the rocks and the occasional grouper.
You will not see coral. The red coral this coast is famous for grows deep, on shaded rock faces well below snorkelling depth, and the shallow stuff is long gone. Anybody suggesting otherwise is selling something.
Masks are provided on the snorkelling trips. Bring your own if you are fussy about fit.
The Grotto boat is a different thing
This confuses people, so to be clear: the boat that takes you to Neptune’s Grotto is not one of these trips.
That is a separate service, from the harbour, run to the cave and back so you can join a guided entry. It exists to save you the 654 steps down the cliff. It runs roughly April to November and it is covered properly in Neptune’s Grotto and Capo Caccia.
The sailing trips on this page may pass the cave mouth from the outside. They do not go in.
When to book, and the wind
Book early in your stay, not late.
This coast is exposed and the mistral can arrive at any time of year. When it blows, the sailing trips shorten, move inside the bay, or cancel outright, and the Grotto boat stops entirely. Having two or three days of slack means a cancelled trip is a nuisance rather than a loss.
Morning is calmer than afternoon almost every day in summer, which is the usual Mediterranean pattern. The exception is the sunset sail, which is worth the slightly livelier water.
Season runs roughly April to October, with the fullest schedule from June to September. In winter there is very little.
What it costs
Checked in September 2026, and these move every season.
A half-day catamaran with an aperitif runs roughly fifty to eighty euros a head. A full day under sail with lunch is around ninety to a hundred and forty. A sunset sail of two or three hours sits at about forty to seventy. A small-group mini yacht with snorkelling is usually in the sixty to ninety band.
Ask two things before you pay: whether snorkelling gear is included, and whether the price covers the marine park fee for Porto Conte, which some operators add separately.
What to bring
A towel, because most boats have none. Something with a back to it for the sun, since there is very little shade on a catamaran and the reflection off the water doubles everything. Shoes you can take off easily. And cash, because the aperitif is included but a second drink usually is not.
Do not bring a hat you are attached to. The wind here is the entire point of the sailing and it takes hats.
What to book before you come
Book early in your stay rather than late, because the mistral cancels trips at any time of year and slack days are what save you.
- The half day catamaran to Porto Conte with an aperitif. The standard trip and the right one for most people. Flat, stable, and you can lie on the netting at the front.
- The sunset sail. If you take only one, take this. The town faces open sea, so the sun goes down into water rather than behind a headland.
- A mini yacht with snorkelling. Smaller boat, smaller group, and considerably more time actually in the sea.
- A full day under sail with lunch on board. For the day you want to spend entirely on the water.
Frequently Asked Questions
Are boat tours in Alghero worth it?
Yes, and more than in most of Sardinia. The best of this coast is the cliff wall at Capo Caccia and the sheltered bay behind it, and neither reads properly from land. Almost half the bookable activities in Alghero are boat trips, which tells you where the town’s real attraction is.
What is the best boat trip from Alghero?
For most people, a half-day catamaran to Porto Conte with a swim stop and an aperitif. If you want the water rather than the sailing, take a small-group mini yacht with snorkelling. If you take only one, make it the sunset sail, because the town faces open sea and the sun sets into water.
How much do Alghero boat tours cost?
Checked September 2026: a half-day catamaran is roughly fifty to eighty euros a head, a full day under sail with lunch ninety to a hundred and forty, and a sunset sail forty to seventy. Ask whether snorkelling gear and the Porto Conte marine park fee are included.
Do boat tours go inside Neptune’s Grotto?
No. The sailing and catamaran trips may pass the cave mouth from outside, but entering the Grotto needs the separate Grotto boat from Alghero harbour or the cliff stairway, plus a guided entry ticket.
When is the best time for a boat trip in Alghero?
Morning, on almost any summer day, because the wind gets up in the afternoon. The season runs roughly April to October. Book early in your stay rather than on the last day, because the mistral cancels trips at any time of year.
