Reviewed · BOA VISTA TOURS
Whale watching tour SEASONAL
Boa Vista’s humpback season brings one of the island’s most powerful sights close to shore: whales gathering in Cape Verdean waters to breed. From mid-February through late May, this small-boat trip gives you a chance to watch them without turning the sea into a noisy circus.
I like two things right away. The group is limited to six, which gives you a much better chance to see over the side and hear the guide. I also like the presence of a marine biologist on every trip, along with rules designed to keep the boat from crowding or disturbing the whales. The catch is simple: nature sets the schedule. One outing produced four sightings, another three, while one person missed the only whale seen.

Humpbacks in Boa Vista’s seasonal waters

Cape Verde sits along a route used by 24 species of whales and dolphins. Boa Vista is especially known for seasonal humpback visits, so this is not simply a generic boat ride with a slim chance of seeing something. The island is part of a much larger marine route where whales feed, breed, and move between areas.
The main attraction is the humpback whale. These animals are famous for their size, surface displays, and powerful blows, but the tour does not promise a staged show. You may see a whale surface several times, or you may have only a quick glimpse before it disappears.
That uncertainty is part of the deal. I would book this trip because the chance of seeing a humpback in open water is special, not because I expected a guaranteed parade of fins and tails. The supplied experiences show the range clearly: one May trip had at least four whales, one March trip saw whales three times, and another March trip produced only one sighting that a passenger missed.

What the boat outing is like

The available information does not give a fixed minute-by-minute route or a stated tour length. You should think of this as a focused whale-watching outing rather than a sightseeing cruise with several scheduled stops. The goal is to reach suitable whale-watching waters, watch carefully, and allow the animals to determine the pace.
A marine biologist stays on board, which matters in two ways. You have someone whose role includes animal and passenger safety, and the boat can follow accepted whale and dolphin-watching practices rather than chasing every movement. In open water, that restraint is important. A whale may surface far from the boat, and the right response is to observe rather than rush in.
The boat is small enough that sightings can feel immediate. One happy passenger specifically appreciated that the small boat made the whales seem enormous when they appeared. That is a real advantage, but it comes with tradeoffs. Small boats can make movement on the water more noticeable, and you have less room to spread out than on a large vessel.
Bring a camera, but keep it ready before the first sighting. A whale can surface and vanish before you have framed the shot. The official packing advice also includes beachwear, a towel, and a head covering or kippah. Fresh water and non-alcoholic drinks are supplied on board.
Why the small group of six matters

A six-person limit is one of the strongest features here. You are not trying to find a clear view through a crowd of people standing at a rail. Everyone has a more reasonable chance to look out, listen to the guide, and react when a whale surfaces.
Small groups also suit people who want a quieter outing. The trip is built around patience. There is no value in six people shouting over one another while a whale is underwater. A smaller group gives the marine biologist room to explain what is happening and remind everyone to respect the animals.
The limit does not turn wildlife into a sure thing. Six people can still spend much of the outing waiting. The benefit is that the waiting should feel more manageable and the actual sighting more personal. If you are choosing between this and a much larger boat, the group size may justify the cost for you.
Eco-friendly rules and responsible whale watching

The operator follows European whale and dolphin-watching laws. The stated aim is to disturb the animals as little as possible while still giving you a worthwhile look. That means you should not expect the boat to charge toward every blow or cut across an animal’s path for a closer photograph.
The marine biologist helps keep the balance between excitement and caution. You are visiting the whales’ environment, not directing a performance. This approach may produce fewer close passes, but it is the right trade for anyone who wants a responsible wildlife experience.
The rules also shape your own behavior. Keep your camera ready, but do not let the search for a perfect picture take over. Listen when the guide asks passengers to wait, stay calm, or give an animal space. The best moment may be a distant blow, a broad back, or the sudden scale of a whale beside the small boat.

Sightings are the great variable
I would make this point before you book: no whale-watching tour can control the animals. The activity gives you access to a good seasonal opportunity, not a guarantee.
The results can vary even within the same month. A March outing recorded three whale sightings. Another March outing had one whale, and the passenger did not see it. In May, an outing produced at least four whales. Those differences do not automatically indicate a poor operator. They show how quickly conditions can change in the open sea and how easily a brief surfacing can be missed.
Your best approach is to allow room for disappointment. If seeing a whale is the only acceptable result, this may not be the right use of your money. If you value the chance, the setting, and the possibility of a powerful encounter, the trip makes more sense.
A camera with a fast response can help, but the supplied information does not specify photography equipment or whether binoculars are provided. Bring what you already use, and do not rely on capturing every moment. Your eyes will often do better than a phone held at arm’s length.
The season, dates, and booking window
The whale-watching season is advertised from mid-February to late May. The activity information also says it is valid for two months, so there is a small timing point to clarify before payment. The full whale season described is longer than two months, while the booking validity appears to cover a particular operating period or date range.
Check the exact starting dates and available times for your visit. Do not assume that every day between February and May is open. The information provided does not give a fixed departure time, and whale conditions may affect the practical schedule.
The seasonal timing is valuable because humpbacks are the main reason to choose this particular excursion. If your Boa Vista trip falls outside the stated period, you should not book it expecting the same whale experience. Cape Verde has other whale and dolphin species, but this tour is specifically promoted around the seasonal humpbacks.
Price, value, and the extra transfer cost

The supplied price information gives two figures: $76 per person in the summary and 65 euros per person in the inclusions. Since those amounts do not match exactly after currency conversion, confirm the final price at booking. That small check can prevent an unwelcome surprise.
At either figure, the value rests on three elements: a small group, a marine biologist aboard, and access to a seasonal wildlife event. Water and non-alcoholic drinks are included, which keeps the onboard arrangement simple. You are paying mainly for the boat, crew, safety planning, and the chance to find whales, not for a long list of extras.
Hotel transport is separate. A one-way transfer to or from central Sal Rei costs 4 euros. The one-way price is 10 euros for Riu Karamboa, Riu Palace, Decameron, and Bravo. Guests at Riu Touareg are offered transport for 50 euros both ways.
That Touareg rate is much higher than the central Sal Rei transfer, so check whether it fits your budget before confirming. If you can arrange your own way to the departure point, compare that option with the paid transfer. The available information does not state that every hotel transfer is included, so treat pickup as an optional paid service rather than a free benefit.
Free cancellation is available up to 24 hours before departure, and you can reserve now and pay later. Those terms are useful when your island plans are still moving, but check the final booking details for the exact date and payment conditions.
Who will enjoy this trip most
This tour suits adults and older children who are happy to wait, watch, and accept an uncertain result. The minimum age is 10, so families with younger children need another plan. It is also a good fit for anyone who prefers a small group and wants a marine biologist present rather than a simple boat ride.
Photographers may enjoy the compact boat and the chance to feel close to the scale of a whale, but they should accept that the action can be brief. Wildlife fans will appreciate the responsible rules and the wider setting, since Cape Verde is used by many whale and dolphin species.
I would be more cautious if you get seasick, dislike open-water uncertainty, or have only one free morning and need a guaranteed attraction. The available information does not describe seasickness support, a fixed route, or a guaranteed sighting policy. Ask the operator directly if those points are important to you.
The tour is conducted in English. If you need another language, make that clear before booking, because English is the language listed for the live guide.
Practical packing for the boat

Keep your clothing simple and useful. Bring beachwear, a towel, a camera, and a head covering. Fresh water and non-alcoholic drinks are provided, so you do not need to plan for those basic onboard drinks.
A camera strap or secure grip is sensible, though equipment rules are not specified. Pack light because this is a small boat with room for only a handful of people. Avoid bringing alcohol or drugs, both of which are prohibited. Explosive substances are also not allowed, an obvious rule but one worth noting for anyone carrying unusual outdoor equipment.
Arrive ready to focus on the water. The whale may appear on either side, and the best sighting may last only seconds. Keep your eyes moving, listen to the guide, and let the person beside you know if you spot a blow. On a small boat, simple cooperation helps everyone get a look.
Should you book the Riamar whale tour?
I would book this if your visit falls in the humpback season, you can handle uncertain sightings, and you value a six-person boat with a marine biologist. The strongest reports describe three or four sightings and a vivid sense of the whales’ size from the small vessel.
I would skip it if you need certainty, are traveling with children under 10, or find the conflicting price and transfer details too unclear. Confirm whether your date falls within the active two-month booking window, verify the final cost in euros or dollars, and decide if you need paid hotel transport.
For the right kind of visitor, this is a thoughtful wildlife outing rather than a guaranteed whale show. Go with patience, keep your camera ready, and remember that even a brief glimpse of a humpback in open water can be the day’s most memorable sight.
