Discover the thrill of open water swimming in Cascais with this guided tour. Enjoy calm seas, expert guidance, and stunning coastal views in Portugal.
If you’ve ever wondered what it’s like to swim in the open ocean with a guide by your side, this Cascais Open Water Swimming tour offers a fantastic introduction. Priced at $68 per person, this experience is more than just a dip in the sea; it’s a carefully curated session designed to boost your confidence, improve your technique, and give you a taste of Portugal’s stunning coastline.
What we love most about this tour is how it combines practical skills with breathtaking scenery. The professional guidance ensures safety and technique improvements, while the early morning sunrise views and calm waters make for a memorable experience.
A potential consideration is that the tour doesn’t include wetsuit rentals, so if you prefer extra warmth or buoyancy, you’ll need to bring your own or plan to rent elsewhere. Plus, since the actual swim locations depend on weather and sea conditions, they can vary from day to day, which keeps things fresh but might affect your planned expectations.
This adventure is ideal for swimmers of various levels who want to enjoy the sea in a safe, guided environment. Whether you’re a beginner eager to learn or an experienced swimmer looking to get in some scenic laps, this tour promises a blend of relaxation and thrill.

Starting at Praia da Duquesa, the tour kicks off with a quick safety briefing and an introduction to the guide—an essential step that sets the tone for safety and enjoyment. The meeting point is well-organized, right next to the public car park and beach access stairs, making it easy to find.
You’ll then warm up briefly, which is crucial for getting your muscles ready and easing any pre-swim nerves. After that, it’s into the water for an acclimatization swim, giving you time to get comfortable with the sea’s temperature and currents. Once you’re ready, you’ll launch into a guided swim along the Cascais coast, with the guide providing real-time feedback on your technique and breathing.
The highlight of the experience is swimming in calm, manageable waters with stunning views of the Cascais bay. Depending on sea conditions, the actual swim could vary in location and length, but most sessions will cover at least 1.5 kilometers—an impressive feat for most swimmers. The guide keeps a close eye on safety, making sure everyone stays comfortable and confident throughout.
One of the standout features is that your guide will take photos and videos during your swim. These can be both inspirational and instructive, providing you with visual references to improve your technique later. It’s a little touch that adds value, especially if you’re trying to document your swimming achievements or share your adventure.
After the swim, you’ll be treated to a warm mug of tea—an appreciated touch to help your body recover and enjoy the post-swim relaxation. Plus, the small group setting means you’re not just another face in the crowd; you’ll get personalized attention, making this feel like a tailored experience rather than a generic tour.
