Seasickness in children: choosing the right boat trip from Vilamoura
Updated September 5, 2026 · 6 min read
You will not find a seasickness remedy here. No brand, no patch, no wristband, no dosage, and no home remedy dressed up as something that works. What a child takes or wears is a question for the pharmacy or for your paediatrician, and it belongs before you travel rather than on the pontoon at Marina de Vilamoura. What this page covers is the other half of the question, and with children it is the more important half: the choice you make before you book. Once you are on the water you cannot get off. Everything that matters is decided beforehand, at the screen.
Boat type moves more than any other lever
A catamaran has two hulls and therefore sits wide in the water. It rolls less around its long axis than a single-hulled boat, and the movement that remains is slower and longer. A small fast boat does the opposite: it follows every single wave, hard and short. No boat lies still, and that is the honest part of the answer, but the difference between the two designs is bigger than anything else you can influence.
From Vilamoura you can have either. On the steadier side there is a catamaran that runs two hours into the sunset for €25, with 253 reviews. A second catamaran spends three hours looking for dolphins and visiting Benagil, a third runs three and a half hours along the coast, both at €45. At the other end sits a boat purpose-built for dolphin watching, small, fast and close to the water: two hours, €40, 381 reviews. For a child who is sensitive in the car, everything appealing about that boat turns into its opposite.
Boat size works in the same direction. A large vessel grinds its way sluggishly through the swell; a small one is lifted by the same wave and set down again. The listing almost always states the boat type, rarely the length. If both are missing, that is the question you put to the operator before you pay.
Two hours or five is not the same thing for longer
With seasickness, duration is not a comfort question. It is the amount of time a child has to endure if things go badly. The town’s most booked trip lasts 2.5 hours and takes in Benagil Cave and the dolphins, €44.10 with 811 reviews. Alongside it sits the same coast in five hours, with brunch and an open bar, €49 with 618 reviews. The open bar already rules the second trip out as a children’s outing; for a sensitive child it would be ruled out without one.
Count the return leg. It arrives exactly when the reserves are gone, and it takes as long as the outbound leg did. Benagil Cave lies around 42 km by road west of Vilamoura, roughly 40 minutes by car. By boat that means a good part of any Benagil trip from Vilamoura is pure distance, in both directions. A short run along the coast on your own doorstep asks far less of a child than a destination half the Algarve to the west.
Why the morning departure is the calmer one
This is meteorology rather than folklore. The summer wind along the Iberian coast, the Nortada, blows from northerly to north-westerly directions and forms thermally, out of the pressure difference between overheated land and a cool Atlantic. It occurs mainly between June and September, typically sets in around midday and holds until the early evening, with peaks up to force 6. The Serra de Monchique takes some of it away from the south coast, which is why the southern side of the Algarve is considerably more sheltered than the west coast. That does not leave it windless: the sea breeze reaches the south coast in the afternoon, and movement comes into the water with it.
For your booking this produces one single, very concrete action. Take the early slot. Not for the photographs and not to avoid the crowds, but because along this coast the sea in the morning is as a rule flatter than it is at four in the afternoon.
Where to sit on board
This is knowledge from being on boats and expressly not medical advice. Movement is smallest amidships, because the bow and the stern swing furthest. Outside in fresh air with a clear view of the horizon suits most people better than an interior cabin, where the eyes find no fixed reference point while the rest of the body is still being rocked. Looking at a phone during the crossing is the worst idea of all.
On a catamaran you will nearly always find such a spot, because there is deck space. On a small boat with fixed rows of seats, not necessarily. Whether seats can be freely chosen, whether there is shade, an interior, a toilet: the operator states this on the booking page, and whatever matters to you should be confirmed before you book rather than discovered on the quay. No minimum age appears in any of the Vilamoura listings; operators set different limits, and they are given on the individual booking page. How to check that is covered at length in the piece on boat trips with kids.
When a trip is cancelled, and what that means for your planning
In heavy swell nobody puts to sea from Vilamoura. The usual pattern is that the operator contacts you in the morning and offers you an alternative date or a full refund; most trips can also be cancelled free of charge up to 24 hours before departure. Nobody can guarantee you that, it is the common practice rather than a promise. In planning terms it mainly means one thing: do not put the trip on the last day of your holiday. Book on Tuesday with a free Friday still in hand and a cancellation costs you nothing but a morning.
When you are better off staying ashore
If your child already goes pale on the drive from the airport, a boat is not the place to test it. A car can pull over. A boat off Praia da Falésia cannot, and three hours then become very long for everyone on board.
Vilamoura is one of the few places on this coast where going without costs little. You can walk the marina for hours with the boats right in front of you. Praia da Marina lies to the east; to the west, after about 1.3 kilometres on foot, Praia da Falésia begins with its red-and-white cliffs. In the town itself there is a Family Golf Park at €18.50 with 288 reviews, and the rest is listed under things to do in Vilamoura, in the piece on Vilamoura with kids and, for the youngest, under Vilamoura with a toddler. A child standing on the pontoon watching the sailing yachts head out is having a good afternoon. A child hanging over the rail for two hours is not.
