Sesimbra: Secret Bays and Beaches Boat Tour with Snorkeling

Sesimbra’s best scenery is along the water, where steep cliffs, sea caves, and little beaches are hard to reach on foot. This 2.5-hour boat trip takes you into protected bays and stops for swimming and snorkeling at places such as Ribeiro do Cavalo and Baleeira.

I like the small group of up to eight, which makes the boat feel personal rather than crowded. I also like the mix of activity: you can snorkel, walk on a beach, listen to local stories, or simply watch the cliffs slide past. The main drawback is sun exposure, since there is no shelter, and some swimming stops may feel short.

Key points

• Small boat, maximum eight people: You get a more personal outing and easier access to the guide.
• Five coastal stops: The route includes Cova, Ribeiro do Cavalo, Mijona, Inferno, and Baleeira.
• Snorkeling equipment included: Swim in the marine park and look for fish and other sea life.
• Wild beaches and sea caves: The boat brings you close to parts of the coast that are awkward to reach by land.
• A regional drink on board: Some departures include a local wine or another regional drink as a pleasant finishing touch.
• Prepare for the sun: Bring a hat, sunscreen, swimwear, towel, and comfortable clothes.

Why Sesimbra’s coast is best seen from a small boat

Sesimbra sits on Portugal’s Setúbal coast, with a shoreline shaped by cliffs, small coves, and clear water. From town, you can see the broad sweep of the coast, but a boat gives you a much better look at the tucked-away places between the headlands.

This tour follows that more intimate side of Sesimbra. Rather than spending the whole outing in open water, you move from bay to bay, with time for photographs, swimming, snorkeling, and short walks. The boat also gets you close to rock formations and water caves that are difficult to appreciate from a distant beach.

I especially like the size of the group. With only eight participants, you are not lost in a crowd, and it is easier to ask about the coastline or get help when climbing in and out of the boat. Guides have included Marco, Vanessa, Jorge, Marcos, Catarina, Andre, and George on different departures, and the crew is able to operate in Portuguese, Spanish, English, and French.

The tone is friendly and relaxed. Guides have taken photographs for people, helped with boarding, explained local ecology and marine life, and added bits of local history along the way. One departure even included an extra drink, while several others included a toast with local wine.

Leaving Blue Coast Tours Sesimbra

You meet the crew at Blue Coast Tours Sesimbra, the stated starting point in Sesimbra. There is no hotel pickup or drop-off, so you need to make your own way to the meeting point.

Before leaving, the crew gives a safety briefing and explains the route. That short introduction matters because this is an active boat trip, not simply a sightseeing cruise. You may be walking on a beach, getting back aboard after swimming, and using snorkeling equipment in open water.

The boat then moves along the coast at an easy pace. You have time to look at the color of the water, the changing cliff faces, and the smaller inlets that are easy to miss from shore. The guides also point out marine life, rock formations, caves, and places of interest.

The activity lasts 2.5 hours, so it gives you a good taste of the coast without taking up a full day. That timing works well if you are fitting Sesimbra into a wider Lisbon District itinerary. It also means the tour has to keep moving. You should expect several short stops rather than one long beach afternoon.

Cova offers the first look beneath the surface

Praia da Cova is scheduled as an early stop, with about 30 minutes for photos, a guided look at the area, snorkeling, and marine life viewing. It is a useful introduction to the trip because you can settle into the boat rhythm before the longer coastal stops.

The water here is presented as clear and calm, making it a natural place to begin snorkeling. You receive the necessary gear on board, so you do not need to bring your own mask or fins. Still, bring your own towel and swimwear, and remember that the equipment is shared tour gear rather than a personal fitted set.

The first swim stop can also help you decide how active you want to be. You can enter the water and look for fish, stay aboard and photograph the cliffs, or simply enjoy the quiet of the bay. The crew gives you room to choose, which is useful for mixed groups where one person wants to snorkel and another prefers to stay dry.

Ribeiro do Cavalo brings the classic beach stop

Ribeiro do Cavalo Beach is one of the most appealing stops on the route. You have roughly 30 minutes for a visit, a short walk, photographs, swimming, and snorkeling.

The beach is known here as a wild, unspoiled stretch backed by cliffs and reached by boat. That access is part of the appeal. You can step onto soft sand without having to spend the day arranging your own route along the coast.

Do not expect a long beach stay. Thirty minutes passes quickly once you have climbed off the boat, taken pictures, walked a little, and decided whether to swim. I would treat this as a chance to feel the character of the place rather than a replacement for a full beach day.

The crew can help you get on and off the boat, which is useful if the water is moving or the beach entry is awkward. The guides also point out nearby rock formations and caves, giving the stop more interest than a simple swim break.

Mijona and Inferno keep the outing moving

Praia da Mijona comes next, with another 30-minute stop for photos, free time, swimming, snorkeling, and marine life viewing. Like Ribeiro do Cavalo, it combines a beach setting with the chance to get into the water.

This part of the route is good for variety. You are not looking at the same cliff from the same angle all afternoon. The boat continues through protected coves, and the guides can show you different rock shapes, narrow inlets, and sections of coast surrounded by vegetation.

Inferno Beach is a shorter stop, listed at about 20 minutes. That is enough for photographs and a quick swim or snorkel, but it is not enough for a leisurely visit. If you want to spend as much time as possible in the water, use the shorter stops efficiently and have your swimsuit ready before the boat reaches shore.

The schedule explains one of the only recurring limitations of the experience: the route covers many places in a short time. You see more of the coast, but no single beach receives an extended visit. People who want a slow day on one beach may prefer a different outing. People who want to see several coves in one trip will likely appreciate the pace.

Baleeira is the relaxed final stop

Baleeira Beach and Bay receive the longest scheduled visit, about 40 minutes. The stop includes sightseeing, free time, swimming, snorkeling, wildlife viewing, and a regional drink.

That extra time gives you a better chance to settle into the water rather than rushing through a quick dip. You can swim, look for fish, take final photographs, or stay aboard and enjoy the bay. The regional drink adds a social finish, and local wine has been part of some departures.

The drink is included, but food is not. Do not count on a meal or a full range of refreshments. Bring what you need for the time on the water, while keeping in mind that the official inclusions specify the boat, guides, life jackets, snorkeling gear, and a regional drink.

Baleeira also provides a final chance to ask questions or hear more about the coast. The return journey gives you another set of panoramic views, this time with a better sense of the places you have visited.

Snorkeling in Professor Luiz Saldanha Marine Park

A major reason to choose this tour is the opportunity to snorkel at Parque Marinho Professor Luiz Saldanha. The marine park protects an important stretch of the Arrábida coast, and the tour uses the water as more than a backdrop.

You may see fish and other marine life near the rocky coast. The clear water helps, although visibility can vary with weather and sea conditions. A cloudy day does not necessarily ruin the trip, but bright conditions can make the colors and underwater views more impressive.

The crew supplies snorkeling equipment and gives guidance about the best places to enter the water. Some departures offer two main snorkeling opportunities, with one separate chance to get out and spend time on a beach. That arrangement makes the experience accessible to people who want a little of everything.

You should be comfortable in the water and ready to follow the crew’s instructions. Life jackets are provided, and the safety briefing comes before departure. The tour is not described as a scuba experience, so think of it as surface snorkeling, swimming, and marine life viewing.

What the guides add to the trip

The scenery would be worth seeing on its own, but the guides make the outing more useful. They explain local ecology, marine life, coastal points of interest, and some local history instead of leaving you to guess what you are seeing.

The crew has also been praised for practical help. Guides have offered to take photographs, helped people board and leave the boat, and made nervous swimmers feel more at ease. That personal attention is easier to provide with eight people than with a large boatload.

The names attached to different departures include Marco and Vanessa, Jorge and Marcos, Catarina and Andre, and George. Crew members can change, but the operation offers Portuguese, Spanish, English, and French. If you do not speak Portuguese, you should still be able to follow the safety information and guiding in one of the other listed languages.

The style is more companionable than formal. You get information, but you also get time to enjoy the quiet. That balance matters because too much narration would distract from the coast, while no explanation would make the caves and bays feel like scenery without context.

What to bring for a comfortable outing

There is no shelter from the sun on the boat, so preparation makes a real difference. Pack:

• Sun hat
• Sunscreen
• Swimwear
• Towel
• Comfortable clothes

Apply sunscreen before boarding and bring enough for reapplication. A hat is particularly useful during the cruising sections, when you may spend several minutes in direct sun between stops.

Wear clothing that is easy to move in. You will be getting on and off a boat, walking briefly on beaches, and possibly changing between sitting, swimming, and snorkeling. Keep your belongings limited and secure, since space on a small boat is not unlimited.

Food and drinks are not included, apart from the regional drink noted by the operator. Plan accordingly, especially if you are booking close to a meal time. The activity is short, but swimming and sun can leave you hungry.

Is the $58 price good value?

At $58 per person, the tour is reasonably priced for a small-group boat trip that lasts 2.5 hours and includes snorkeling equipment, life jackets, guiding, several coastal stops, and a regional drink.

The value comes from the combination rather than one single feature. A simple cruise might show you the cliffs, but this outing also lets you swim, snorkel, step onto a wild beach, and enter protected bays. A land-based beach visit might give you more time on one stretch of sand, but it would not offer the same view of the caves and cliff line from the water.

The group limit is another important part of the price. Eight people is small enough for direct contact with the crew, help with equipment, and a less crowded feel. If the boat were packed, the short stop times would feel more restrictive. In this format, the pace is easier to accept.

The price makes the most sense for active sightseers who want several experiences in one compact outing. It is less suitable if your only goal is to lie on a beach, eat lunch at sea, or spend hours snorkeling in one place.

Free cancellation up to 24 hours before the activity and the option to reserve now and pay later also make the booking more flexible. Starting times vary, so check availability for your chosen date.

Who should book this Sesimbra boat tour?

I would choose this trip if you want to see the Sesimbra coast from the water without committing to a full-day excursion. It suits couples, friends, families with older children, and solo visitors who enjoy a friendly small-group setting.

It is especially good for you if:

• You want swimming and snorkeling as part of a sightseeing trip.
• You prefer several coves to one long beach stop.
• You enjoy hearing about local ecology and coastal features.
• You appreciate a guide who can help with photographs and boarding.
• You are comfortable spending the full outing in the sun.

Think twice if you need shade, want a long uninterrupted swim, or dislike changing locations often. The boat visits many places, but the stops are brief. Some people may wish the swimming time were longer.
