Benagil, brunch and an open bar: what €49 for five hours out of Vilamoura actually covers
Updated September 5, 2026 · 8 min read
The title of this tour makes two promises: brunch and an open bar. The booking page carries four numbers: €49 per person, five hours, 4.6 stars, 618 reviews. That makes it the sixth most-booked departure out of Vilamoura. What the operator himself writes about the drinks can be summed up in a single word: nothing.
The description does not name a single drink
The operator gets by with two sentences: a trip from the marina, Benagil as the destination, a refreshing swim, brunch on board. That is the whole text. The two words that set this tour apart from the other cave trips – open bar – appear nowhere in it. They live in the headline and nowhere else.
This is not fraud, but it is a gap, and the mind fills gaps with whatever it expects. One reader pictures beer and wine from the moment the lines are cast off, another pictures a bottle of water with the brunch. Both have read the same page. Four questions are therefore due before you book, and they belong in a message to the operator: which drinks exactly, from what point in the trip, are they served on board or only at the swim stop, and what do children get instead.
“Open bar” is not a protected term
There is no definition an operator would have to meet. The phrase is an advertising line, not a specification. In the Vilamoura listings it turns up a second time: on the sunset boat party with its DJ, two hours for €27, sitting at 4.6 stars from 445 reviews. Different vessel, different length, different time of day, same two words – which on their own say nothing at all about the contents. Where the evening departures sit on price is set out under sunset cruises: six offers, from €25, median €42.50.
Who may pour, and for whom: 18 years
Here the legal position is clear, unlike the advertising line. The governing text is Decreto-Lei n.º 50/2013 of 16 April 2013 as amended by Decreto-Lei n.º 106/2015 of 16 June 2015, in force since 1 July 2015. It prohibits supplying alcoholic drinks to minors, selling them, or making them available for commercial purposes, in public places and in places open to the public. Minors are also barred from drinking there. In Portugal you come of age at 18.
The 2015 amendment is the reason older guidebooks still quote different figures. Until then there was a split: beer and wine earlier, spirits later. Since 1 July 2015 one single limit applies to every alcoholic drink. An excursion boat whose seats are sold to the public is not carved out of that, and the crew enforces it. For fifteen to seventeen-year-olds this means something plain: they come along, they get no alcohol – Vilamoura with teenagers.
A minimum age for the tour itself is not stated by the operator. Where the line falls is each business’s own decision; the figure sits in the booking details, not in the title: boat trips with kids, from what age.
Brunch on board means eating on a moving boat
No table, no plates that stay put, no second helping from a kitchen. What is usual is a cold buffet or a packed set, handed out during the calm stretch of the programme, while the boat is anchored or running slowly, and not on the fast passage. When exactly, the operator will tell you, and that determines whether someone should set off on a light breakfast or on a full one.
What gets served is written down nowhere. That is why allergies and intolerances are a question before booking and not one on the pontoon – no substitute is going to be fetched there. The same goes for vegetarian or vegan: often possible, promised by nobody, and a note the day before achieves more than one at the moment of departure. How to catch that on land when a meal falls through is what eating out with kids sets out.
And then the toilet. On two and a half hours with no catering it is a comfort detail you overlook. On five hours with food and drinks it is a different question altogether. Whether there is one and whether it is reachable under way goes into the same message.
Where the five hours go
Not into more time inside the cave. This is the point at which most people miscalculate. How long a motorboat is allowed to stay in there is set by the authorities and is identical for both trips – the detail is in the short Benagil trip from Vilamoura. Inside Benagil Cave your visit is just as brief here as it is there.
The difference lies elsewhere, and the description says so itself: it names a swim. The shorter version names none. The stop in open water is the real reason for the additional hours, along with the meal and the longer stretch along the cliff coast. Book five hours and you are buying a swim stop and a meal, not more cave. Which trip matches which expectation is worked through in which boat trip suits you.
€9.80 against €17.64 an hour
The arithmetic is short. €49 across five hours comes to €9.80 an hour. The short trip costs €44.10 across a run of two and a half hours, which works out at €17.64 an hour.
Two sentences follow from that, and both hold. Anyone who only wants to see the cave and be back at the pool by midday is paying here for time they never wanted – the hourly rate is beside the point, the hours are the problem. Anyone with half a day free anyway gets twice the programme for €4.90 more, and that is the clearer value. Where the €49 sits among the other prices is shown in the price overview for Vilamoura.
Sun, salt water, five hours without shade
An excursion boat rarely has a roof over every seat, and the sun over the Algarve stands high at midday. Alcohol, heat and swimming all land on the same afternoon here, over twice the stretch of the short trip. What follows from that is what common sense says, not a manual: carry drinking water, cover your head, and know how much you have drunk before you go over the side into open water. Anyone sensitive to sun or to movement on board settles that beforehand with a doctor or a pharmacy – nothing on that stands here, because nothing can.
Whether the boat sails at all is decided by the sea – boat trips in rough seas – and which month brings which conditions is shown in the best time to visit Vilamoura.
When this is the wrong booking
With small children. Five hours with no way off, an open bar among adults and a swim stop in open water are manageable one at a time and wearing all together. The shorter version is almost always the better call here, for the same reason that half a day instead of a full day with kids works.
With a delicate stomach. Eating on board and moving about in the water do not agree with everyone, and five hours give the problem more room than two and a half: seasickness in children. A wide hull rides more steadily – nine offers in the listings are built that way, though at a median of €160 they are considerably dearer: catamaran tours.
And for anyone whose sole objective is the cave. Then every minute that does not lead there is paid waiting time, and there are two and a half hours more of it here than necessary. Benagil cave tours from Vilamoura lists eighteen departures, the cheapest from €23.20.
4.6 against 4.8 – more programme, the poorer score
This tour sits at 4.6 stars, counted across 618 reviews. The short trip along the same coast sits at 4.8 across 811. That is the weaker rating on the larger offering, and it cannot be talked away.
Nor can it be explained, at least not honestly – the cause is in none of the numbers available here. Only the structural point can be made: an offering with a crossing, a cave, a swim stop, food and a bar has five parts where something can fail to fit. One with a crossing and a cave has two. The more that is promised, the more chances there are of falling short of it – and asking before you book is exactly what guards against that: booking mistakes in Vilamoura.
Where the €49 sits in the whole catalogue
There are seventy-three offers out of Vilamoura, the cheapest at €6, with a median of €57. At €49 this trip sits just under that.
Anyone wanting to fill the other half of the day has a choice: things to do in Vilamoura lists thirty-two offers from €6. If the appeal is in the water rather than on the boat, five offers from €40 lead there: water sports.
