    Nice Tour

    Everything was organized well and the ride to the dolphins was very nice. On the ride back it was very nice that the crew provided a snack and a bit of wine. I would have given 5 stars except for the fact that I was waiting to be provided quite a lot about dolphins from a real “Marine Biologist” as per the title of the tour. We were only provided basic information and the crew were definitely not experts in marine biology. I was happy with all other details of the trip but my suggestion would be to change the title of the tour to accurately reflect the crew’s credentials and manage passenger expectations.

    Response from the operator: Thank you very much for your review and for sharing your experience with us. We are delighted to hear that you enjoyed the tour, the dolphin sightings, and the hospitality of our crew on board. We also appreciate your feedback regarding the marine biology information provided during the trip. On some departures, our marine biologist may not be available due to scheduling, and in those cases the tour is conducted by our experienced crew members, who always do their best to share accurate and interesting information about the dolphins and the local marine ecosystem. We understand your point regarding the expectations created by the tour title and appreciate you taking the time to share your thoughts. Feedback like yours helps us continue improving both our communication and the overall experience we provide. If you left the tour with any unanswered questions about dolphins or marine life, we would be more than happy to help. Simply send us an email at info@vertentenatural.com, and we will gladly forward your questions to our marine biologist, who will be happy to provide further information. We would also be delighted to welcome you back in the future and offer you the experience. If you contact us in advance, we will do our very best to schedule your tour on a date when our marine biologist is confirmed to be on board, ensuring an even more enriching experience. Thank you once again for your valuable feedback, and we hope to see you again in Sesimbra.

    Marta & Leonor made it extraordinary!

    An absolutely unforgettable experience! During our meeting in Sesimbra we had the chance to go out to sea with Vertente Natural and it was simply extraordinary. Marta and Leonor, besides their contagious friendliness, showed incredible professionalism: they never gave up until we found the dolphins and managed to give us a true spectacle of nature. This is not just a boat trip, it’s an experience that combines dedication, knowledge, and passion for what they do. We always felt safe, well taken care of, and above all, amazed by the team’s positive energy. I strongly recommend this to anyone visiting Sesimbra: don’t miss the chance to live this adventure with Vertente Natural. Marta and Leonor truly deserve all the recognition for the outstanding work they do.

    Response from the operator: What a fantastic review! We are so grateful for your kind words regarding your Dolphin Watching at Arrábida experience. Providing a safe, insightful, and truly magical experience is our top priority, and we are delighted to hear that our team's dedication, knowledge, and positive energy shone through. It's wonderful to know that Marta and Leonor's commitment to finding the dolphins created such an amazing adventure for you. We believe our team's passion is what transforms a boat trip into an unforgettable nature experience. Thank you again for your high recommendation. Your support means the world to our small team here in Sesimbra. We hope to see you again soon!

    Good customer service.

    This is a review of their customer service as we never went on a trip due to the awful weather that day. We dealt with Patricia in the Lisbon office who was so good and concerned of our disappointment in not being happy going out in the terrible weather for 3 hours dolphin watching. I explained that we were leaving that day so they offered an immediate refund, as we couldn't sadly do another day, which they offered. Therefore, our gratitude to them for not making a fuss and when we got home they refunded the money without quibble a few days later. Great customer servie and we will definitely recommend this company to you.

    Response from the operator: Thank you so much for this wonderful feedback! We were so sad that the weather kept you from joining us on the water. We always want our customers to have the best possible experience, and sometimes that means making the tough call to cancel for safety and comfort. We're thrilled to hear that Patrícia and our team made the process easy for you. Your satisfaction is our top priority, and we appreciate you highlighting our customer service even though you didn't get to see the dolphins. We're looking forward to having you with us on a future trip!

    Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Lisbon.

    How much does Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation cost?

    +

    Prices start at $25 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Lisbon usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation take?

    +

    Plan for about 2.5 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Lisbon is not rushed.

    Is Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation worth it?

    +

    It holds an Outty Ranking of 78 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 57 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Lisbon, and how flexible the cancellation terms are.

    Can I cancel or reschedule Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation?

    +

    Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

    Is Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 2.5-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation?

    +

    Around 20 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Lisbon can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Lisbon and add a light layer if any part of the 2.5-hour experience runs outdoors or after sunset.

    Where does Sesimbra - Dolphins c/ Marine Biologist + Quick Embarkation start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Lisbon within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Lisbon?

    +

    On Outty we rank every Lisbon experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Lisbon City Center Tour - The Unmissable Lisbon, Sintra Private Trip from Lisbon Customizable Dreamlike Experience, True 4Hour Private Tuk Tuk Tour: Discover Lisbon with a Local!. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Lisbon?

    +

    Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Lisbon?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
