Private sessions
I had private sea swimming sessions with their guides who were very helpful and friendly. I feel much more confident in the sea and I have some good tips to work on at home. Would really like to come back someday.
Response from the operator: Thank you so much for your lovely review! 🌊 We’re delighted to hear you felt well looked after by our guides and that you’re leaving with more confidence in the sea and some tips to keep practising at home. That’s exactly what we hope for. You’ll always be welcome back, and we’d love to swim with you again. Until then, keep enjoying the water!

Highlight of my trip!
Oh my goodness this was so great!! I am a solo female traveller and this experience was amazing. Arseniy was my guide and we had so much fun. I haven’t done a lot of free water swimming but he helped me with figuring out my breathing and went at my pace. Easy instructions to meet each other one the morning of. Super friendly and accommodating. He even found me an octopus while we were swimming. Truly a great experience and a highlight of my trip. Really love to know companies like this are out there for people travelling on their own! Thank you!
Response from the operator: Rebecca, thank you so much for such a lovely review! We’re delighted you had such a great time, and it was a pleasure to have you join us. I’ll make sure to pass your kind words on to Arseniy, who will be thrilled to hear that the breathing tips helped and that the octopus made an appearance! Open water can feel a bit daunting at first, so it means a lot to know you felt comfortable and could go at your own pace. Making solo travellers feel welcome is exactly what we hope to do, so your message really made our day. Thank you again, and we hope the sea brings you back to us one day!

Great trip with SwimTogether Swimming Holidays
Came with a group of friends on a swimming and water polo tour. We decided to go with SwimTogerher Swimming Holidays and we were so glad we did. Great people, great tour, lovely experience and very warm welcome.
Response from the operator: Thank you so much for such a kind review! It was a real pleasure to host a water polo team in the water for a different kind of challenge. Swimming side by side as a group is a great way to experience the coast, and we’re delighted you all felt so welcome with us. Thank you for choosing us to share this swim. We’d love to see you back for another adventure!

Why this scores 82
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Open-Water Swimming in Cascais: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Cascais.
How much does Open-Water Swimming in Cascais cost?
+
Prices start at $57 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Cascais usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Open-Water Swimming in Cascais take?
+
Plan for about 1 hour 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 Cascais is not rushed.
Is Open-Water Swimming in Cascais worth it?
+
It holds an Outty Ranking of 82 out of 100, which we label "Exceptional". That score blends traveler sentiment (5/5 across 85 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Cascais, and how flexible the cancellation terms are.
Can I cancel or reschedule Open-Water Swimming in Cascais?
+
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 Open-Water Swimming in Cascais suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Open-Water Swimming in Cascais?
+
Around 30 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 Cascais 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 Cascais and add a light layer if any part of the 1-hour experience runs outdoors or after sunset.
Where does Open-Water Swimming in Cascais 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 Cascais 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 Cascais?
+
On Outty we rank every Cascais experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Surf Experience in Cascais, Best of Sintra Private Tour with Local Guide & Hotel Pickup, E-bike in the backroads of Cascais and Sintra. 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 Cascais?
+
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 Cascais?
+
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.

Included: Swim cap (our offer); Experienced guides; If you need, we can provide a swim buoy; Personal Accidents Insurance; and Photos and videos included. Not included: Tips for your guides; and Wetsuit rental (€30/person). Always check the voucher for the final list before you travel.
Where is the meeting point for Open-Water Swimming in Cascais?
+

What languages is Open-Water Swimming in Cascais offered in?
+
It is offered in Portuguese, English and Spanish. Pick your language when choosing a date and time, as not every departure runs in every language.
Will I get instant confirmation and a mobile ticket for Open-Water Swimming in Cascais?
+
