Starting Point: Praia da Duquesa

Your adventure kicks off at Praia da Duquesa, a lovely beach with accessible facilities and close proximity to public transportation. Here, you’ll meet your guide, who’s usually a seasoned swimmer and instructor. We found that for many, this initial meet-and-greet offers reassurance—especially if nerves are involved.

The guide begins with a brief safety briefing and a discussion about your swimming experience and goals. Whether you’re a beginner or more experienced, this initial chat helps tailor the session. As one reviewer commented, “Gustav, our guide, was very friendly and adaptable to our schedule and skill level,” highlighting the personalized approach.

Acclimatization and Route Planning

Before hitting the water, there’s a chance to get comfortable with the environment. An acclimatization swim nearby helps you adjust to the water temperature and conditions. Expect some gentle splashing and orientation around safety gear, like the provided swim buoy or wetsuit rental, if needed.

The guide then plans a route along the cascading coastline, which varies from 1.5 km to longer distances based on your preference and ability. This flexibility is key — you can opt for a short, enjoyable swim or push further in this safe, controlled environment.

The Main Swim: Scenic Beauty and Skill Building

Once underway, you’ll swim along a route with unbeatable views of Cascais’ bay and cliffs. The water is generally crystal clear, making sighting and breathing easier. We loved the way the guide constantly supported swimmers, offering real-time feedback on stroke technique, breathing, or even mental anxiety.

A notable aspect is the focus on technique and confidence-building. You’ll learn breathing techniques, key for maintaining calm in open water, and anxiety management strategies, especially useful for those new to ocean swimming. As one happy participant shared, “Gustav was very didactic and friendly, making me feel confident even as a beginner.”

Post-Swim Relaxation and Video Analysis

After your swim, there’s time to warm up with hot tea — a simple, appreciated touch. More than just a break, this pause gives everyone a chance to chat about the experience and share impressions.

What sets this tour apart is the video footage and photos taken during the swim. Your guide films you swimming, then provides an analysis that can help you identify areas for improvement. This personalized feedback is rare in guided outdoor activities and offers real value, especially if you’re serious about developing your skills.

Who Will Love This?

This experience suits a broad range of swimmers, from those wanting to conquer their fears to seasoned ocean swimmers seeking professional tips. The small group size (up to 10 people) fosters a supportive atmosphere, and the flexible route lengths mean it can be tailored to your comfort level.

However, it’s worth noting that weather conditions impact the experience. If the sea is rough or the weather poor, the session might be canceled or rescheduled, with a full refund offered. Also, wetsuit rental costs $30 if needed, which adds to the overall value when compared to the cost of private lessons or other guided activities.

The Overall Value

At just under $60, this tour provides personalized instruction, professional guidance, and a beautiful setting — all in a compact, one-hour session. The inclusion of photos and videos enhances the value, giving you tangible memories and insights to improve your swimming.

Even with the occasional hiccup noted in the reviews — such as a guide missing in one instance — the overall feedback is very positive. Most reviewers praised the knowledgeable guides and the friendly, adaptable atmosphere. One comment summed it up: “Muy buen profesor. Amabilidad y didáctico.” (Very good teacher. Friendly and instructive.)
