What Makes This Tour Stand Out?

This Cascais open-water swim provides more than just a splash in the sea. We loved how the tour balances technical instruction with scenic relaxation. The guide, whose name isn’t mentioned but clearly experienced, offers feedback throughout, helping you refine your breathing, stroke, and anxiety management techniques. If you’re new to open-water swimming or looking to boost your confidence, this guidance can be invaluable.

Another highlight is the setting—the pristine beaches, the soft sunrise light, and the calm waters create an environment where you feel both relaxed and invigorated. The fact that the water temperatures are described as “perfect” suggests you won’t be battling the chill that often deters novice swimmers from trying open water.

The tour’s inclusion of photos and videos earns high marks from travelers, giving you a chance to see your form and relive the experience long after. Plus, the hot tea at the end offers a cozy finishing touch, warming you after your swim.

What to Expect from Your Cascais Swim

Your experience kicks off at Alameda Duquesa de Palmela 29, where your guide welcomes you with a quick safety briefing. Expect to spend a few moments warming up—crucial for acclimatizing to the water—and then, after a brief acclimatization swim close to shore, you’ll venture into the open sea.

The main swim along the Cascais coast can last up to an hour, covering at least 1.5 kilometers. As you swim, you’ll be treated to views over the Bay of Cascais, with plenty of photo opportunities, especially if the weather cooperates with a clear sunrise. Your guide will provide ongoing feedback to improve your technique, whether you’re adjusting your breathing or working on your stroke efficiency.

Safety is a priority—participants are equipped with a swim buoy and swim cap, and the guide ensures everyone is comfortable and aware of potential marine life like jellyfish or seaweed. You’ll also learn how to read weather and current conditions, skills that are useful beyond this tour.

After your swim, you’ll return to shore for a warm mug of tea, giving you a moment to relax and chat about the experience. The entire activity lasts about an hour, but with the warm-up, briefing, and photo session, it feels like a well-paced adventure.

The Practicalities: Price, Group, and What’s Included

For $68, this tour offers a decent value for a personalized outdoor activity with a professional guide. The price includes essential safety gear—swim buoy, cap, and photos/videos—which are significant perks. Personal accident insurance provides peace of mind, and the small group size ensures individual attention.

The tour does not include wetsuit rental, so if you’re sensitive to cold or prefer extra insulation, bring your own or plan to purchase or rent locally. With only up to 10 participants, it remains intimate, allowing for personalized coaching and a supportive atmosphere.

Starting from Praia da Duquesa, the meeting point is convenient, with easy access from the nearby public car park. The activity ends back at the same spot, making logistics straightforward.

Who Is This Tour Best For?

This experience is ideal for swimmers of all levels who want to enjoy Cascais from a different perspective. It’s perfect for travelers seeking an authentic coastal adventure combined with professional guidance to improve technique or build confidence. It suits those who appreciate scenic beauty, calm waters, and small-group intimacy.

If you’re someone who enjoys learning new skills in a relaxed setting, or simply wants a peaceful, scenic swim in Portugal’s stunning coastline, this tour hits the mark. Families or groups with varying swimming abilities will find the guide’s attention reassuring, and the photos provided make great souvenirs or social media content.
