Sesimbra: Secret Bays and Beaches Boat Tour with Snorkeling

Sesimbra’s best scenery is offshore. This 2.5-hour boat trip threads along Portugal’s wild Arrábida coast, stopping at quiet bays, sea caves, and beaches that are difficult to reach by land. I especially like the small group of up to eight people and the chance to swim and snorkel in the Professor Luiz Saldanha Marine Park. The main drawback is simple: there is little or no shade on the boat, so the Portuguese sun deserves respect.

I also like the friendly, hands-on service. Guides such as Marco, Vanessa, Jorge, Marcos, Catarina, and André have been praised for explaining the coast, helping people on and off the boat, taking photos, and making nervous swimmers feel at ease. The stops are beautiful and varied, though the swimming and beach breaks can feel short if you want a long, lazy afternoon in the water.

Key points at a glance

• Small boat, maximum eight people: You get a more personal outing than on a large sightseeing vessel.
• Five coastal stops: The route includes Praia da Cova, Ribeiro do Cavalo, Praia da Mijona, Inferno Beach, and Baleeira Bay and Beach.
• Snorkeling gear included: Swim and look for marine life in the clear waters of the Professor Luiz Saldanha Marine Park.
• A mix of activity and quiet: You can snorkel, swim, walk on the sand, take photos, or simply sit back as the cliffs pass by.
• A local drink on board: The tour includes a regional drink, with wine tasting listed at Baleeira Beach.
• Bring sun protection: Pack a hat, swimsuit, towel, sunscreen, and comfortable clothes because shade is limited.

Why a small boat makes Sesimbra better

Sesimbra sits beside a dramatic stretch of coast, with steep cliffs, rough rock formations, sea caves, and tucked-away beaches. From the road, you see only part of it. A boat gives you the proper view: cliffs rising from the water, cave mouths opening along the shoreline, and beaches appearing around corners with no easy road access.

The group size matters here. With no more than eight participants, the crew can answer questions, suggest good places to snorkel, and help you get in and out of the boat. It also makes the ride feel less like a scheduled parade and more like a shared outing with a local crew.

The tour is run by Blue Coast Tours Sesimbra, with Portuguese, Spanish, English, and French available. That language range is useful in a small group, especially when the guide is explaining safety instructions or pointing out marine life.

You meet at Blue Coast Tours Sesimbra in Sesimbra. There is no hotel pickup or drop-off, so you need to arrange your own way to the meeting point. Once everyone is aboard, the crew gives a safety briefing and explains the route before heading along the coast.

Praia da Cova: a gentle start with clear water

The first listed stop is Praia da Cova, where you get a photo stop, a guided look at the coast, and time for snorkeling and marine-life viewing. The planned stop lasts about 30 minutes.

This is a useful opening to the trip because you can settle into the boat before the more active parts begin. The water is described as calm and clear, and the crew uses the stop to introduce the coastal setting. If you have not snorkeled recently, this is a good moment to get used to the equipment.

Do not expect a full beach day at this point. Thirty minutes passes quickly once you account for instructions, getting ready, swimming, and returning to the boat. Think of Praia da Cova as an early taste of the water rather than the main event.

Ribeiro do Cavalo Beach: the famous sandy pause

Ribeiro do Cavalo Beach is one of the most appealing stops on the route. You have time to visit, walk, take photos, swim, and snorkel, with about 30 minutes scheduled here.

The beach is framed by steep cliffs and clear water. Its remote feel is a big part of the attraction. Reaching it by boat lets you enjoy the setting without turning the day into a demanding coastal walk.

This is also the stop where expectations matter most. The tour gives you time to step onto the sand, but not enough for a long walk or a slow picnic. You will want to keep an eye on the time and follow the crew’s instructions when it is time to return to the boat.

For photographers, Ribeiro do Cavalo is one of the strongest parts of the route. The combination of pale sand, rocky cliffs, and bright water gives you plenty to look at even if you decide not to swim.

Praia da Mijona: snorkeling in a quiet cove

The boat continues to Praia da Mijona, also called Cova de Mijona in the broader description. This stop lasts about 30 minutes and includes time for photos, swimming, snorkeling, and marine-life viewing.

The appeal here is the calm setting. The boat reaches a protected bay surrounded by cliffs and vegetation, giving you a peaceful place to get into the water. Several people who enjoyed the tour singled out the snorkeling and the chance to see fish in the clear sea.

The snorkeling is recreational rather than a formal wildlife expedition. You receive equipment on board, and the crew can point you toward good areas, but sightings depend on water conditions and nature. The trip works best if you enjoy looking around in the water without expecting a large reef or guaranteed animals.

If you prefer staying dry, this is still a worthwhile section of the cruise. The cliffs, rock shapes, and changing views provide plenty of scenery from the boat.

Inferno Beach: a short stop with a wild edge

Inferno Beach receives around 20 minutes, making it the briefest scheduled stop. You can take photos, swim, snorkel, and look for marine life.

The name suggests something dramatic, and the setting fits the mood: rough cliffs, exposed rock, and a more remote coastal feel. This is a quick chance to get in the water or capture a few pictures before the boat moves on.

The short timing can be a limitation. If you need several minutes to prepare for snorkeling, your actual time in the water may be modest. I would treat this stop as an extra opportunity rather than the place to plan your best swim.

Baleeira Bay and Beach: the relaxed finish

Baleeira Bay and Beach is the final major stop, with about 40 minutes. It combines a boat cruise, sightseeing, swimming, snorkeling, marine-life viewing, and time to visit the beach. Wine tasting and a regional drink are also part of the experience here.

This longer pause gives the trip a more relaxed finish. You can choose how active you want to be. Go into the water, walk on the beach, take photos, or enjoy the drink while looking back at the coast.

The included regional drink is a pleasant local touch, and several people particularly enjoyed having wine on board. It adds a social note without turning the tour into a drinking excursion. Food and other drinks are not included, so eat beforehand or bring only what the operator permits on board.

Baleeira is also a good place for the crew to help with photos. The guides have been praised for offering to take pictures, sharing group photos, and helping participants step safely on and off the boat.

Snorkeling in the Professor Luiz Saldanha Marine Park

The snorkeling takes place in the protected waters of the Professor Luiz Saldanha Marine Park. You receive snorkeling equipment and a life jacket, so the basic gear is covered.

The clear water is the star. You might see fish and other signs of marine life close to the rocky shore, though the exact conditions will depend on the day. Several outings have been described as having excellent snorkeling, with plenty of fish visible even on a cloudy day.

You do not need to be an expert swimmer to enjoy the water, but you should be comfortable in the sea. The crew provides safety instructions and helps people feel comfortable, yet this remains a boat-and-water activity. If you are unsure, ask the guide for help before entering.

Bring your own towel and swimsuit. Sunscreen is essential, even when the day looks cloudy. A hat and comfortable clothes will make the boat ride easier, but secure your hat when the boat is moving.

The crew and the feel of the outing

Service is one of the strongest parts of this experience. The guides have been praised for being friendly, attentive, informative, and helpful without making the trip feel stiff. Some have offered to take photos, helped people board, and shared local recommendations.

Marco and Vanessa have led outings praised for clear explanations and warm service. Jorge and Marcos have also been singled out for making people feel comfortable, especially during snorkeling. Catarina and André were praised for creating special moments and sharing information about the coast.

The crew’s local knowledge adds value because the coast is not just a series of pretty beaches. The guides explain points of interest, local ecology, marine life, caves, and rock formations as you pass. The information gives the scenery more meaning, while the small group leaves room for questions.

One unusual strength is the crew’s flexibility. On one outing, a couple received a private trip when other people did not show up, rather than having the activity canceled. That should not be treated as a guarantee, but it shows the personal level of service this operator aims for.

What the $58 price really covers

At $58 per person, this is not the cheapest way to see the coast, but the price is fair for what is included. You receive a 2.5-hour boat trip, local guides, life jackets, snorkeling gear, several coastal stops, and a regional drink.

The small group is the key value. You are paying not just for transportation, but for access to coves and beaches, help with the equipment, local explanations, and a more personal experience. A large boat might offer a lower price, but it would not provide the same easy contact with the crew.

The tour is especially good value if you plan to snorkel. Renting equipment separately, arranging a boat ride, and finding these coastal spots on your own would take more effort. You also get a mix of sightseeing, swimming, beach time, and a local tasting in one compact outing.

The value is less clear if you want hours on one beach. The stops are carefully timed, and the swimming breaks can feel short. You are buying variety and access, not a slow beach holiday.

Timing, comfort, and practical planning

The total duration is 2.5 hours, with starting times depending on availability. That makes it easy to fit into a day in Sesimbra. You can use it as a morning activity, an afternoon break from sightseeing, or a compact coastal outing before dinner.

The boat has limited shade. This is the most important comfort warning. Wear sunscreen, bring a hat, and consider a light cover-up. The sun can feel strong on the water because there is little protection.

Pack:

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

Food and drinks are not included, apart from the regional drink listed as part of the tour. Since the activity is only 2.5 hours, a meal before or after should be easy to arrange, but do not assume that snacks will be provided.

The tour offers free cancellation up to 24 hours in advance for a full refund. You can also reserve and pay later, which helps if your Lisbon plans are still shifting. Check the available departure time before booking.

Who should book this Sesimbra boat tour?

I would recommend it to couples, families with older children, solo visitors, and small groups who want an active coastal outing without giving up time to relax. It is a good match if you like swimming, snorkeling, photography, caves, and small-group service.

It also suits visitors who want to see several beaches in one trip. The boat handles the movement between stops, while you get short chances to explore the sand and water. That is much easier than trying to reach each place separately.

You should think twice if you dislike boats, cannot swim comfortably, or need guaranteed shade. The tour also may not satisfy you if your priority is spending half a day at one beach. The schedule favors variety, and the 20 to 40-minute stops move along at a steady pace.

The perfect day is calm, sunny, and clear, but the outing can still be worthwhile in cloudier weather. The cliffs, caves, and coast remain impressive, and the crew continues to provide information and support.

Should you book it?

Yes, if you want a compact, personal way to see Sesimbra from the sea. The route packs five coastal stops, snorkeling, caves, beach time, and a local drink into 2.5 hours. The strongest reasons to book are the small group, the warm crew, and access to beaches that are awkward to reach from shore.

Just arrive prepared for sun and a brisk schedule. Bring your swimsuit, towel, sunscreen, and realistic expectations about stop lengths. If you want a long swim or a full afternoon on Ribeiro do Cavalo, choose a beach day instead. If you want variety, clear water, and a friendly crew, this is one of the better-value boat trips around Sesimbra.
