The Experience: What to Expect from Start to Finish

Location and Setting
The course takes place at Mega Dive Center in Sesimbra, Portugal, right on the Atlantic coast. The surrounding landscape, especially the Arrábida Biosphere Reserve, makes for a stunning backdrop and enriches the dive experience with impressive natural beauty. The site is known for its calm waters, which are ideal for beginners. If you’re worried about turbulence or currents, rest assured—the Atlantic here is generally gentle, making your first ocean dives more relaxed.

Day 1: Theoretical Learning and Equipment Familiarization
The first day kicks off with classroom or pool-based theory, where your instructors will explain the basics of scuba diving, safety procedures, and equipment. This part is crucial because understanding what’s happening underwater helps build confidence. Reviews from previous participants describe the instructors as “knowledgeable” and “patient,” which makes the learning process less intimidating. You’ll also get a chance to try out the gear on land, familiarizing yourself with the mask, fins, and regulators.

Day 2: Skills Practice in Controlled Water
The second day involves practicing essential skills in a controlled environment—usually a swimming pool or shallow water. This is where you’ll learn how to clear your mask, control your buoyancy, and manage your regulator. The goal is to build comfort and competence before heading into the open ocean. Many reviews highlight the instructors’ calm and safety-focused approach here, helping even the most nervous participants feel at ease. Expect to spend a few hours mastering these skills, which are fundamental for your confidence underwater.

Day 3: Open Water Dives
The final day is the highlight—your actual ocean dives. You’ll complete five dives in the Atlantic, exploring the marine environment that’s part of the UNESCO Biosphere Reserve. These dives are typically scheduled with flexibility, but the general flow involves arriving early, reviewing safety procedures, and then heading out into the water. You’ll be diving with your instructor and possibly a small group, which ensures personalized attention.

What You’ll See and Feel
During your ocean dives, you can expect to see an array of marine life, from small fish to possibly larger species, depending on the day. The calm waters and rich biodiversity make for memorable sights. Many reviewers mention the “beautiful surroundings” and “the feeling of floating in open water,” which is truly special. The instructors will continuously monitor safety, guiding you through each step, making sure you’re comfortable and confident.

The Certification and What Comes Next

Upon completing the course, you’ll earn an Open Water Diver certification recognized worldwide. This allows you to dive up to 18 meters independently with a buddy, rent gear at dive centers around the world, and continue exploring the underwater world. It’s a game-changer—once certified, you’ll see the ocean in a different light and be equipped with a skill that can turn travel into a lifelong hobby.

Value-wise, the course costs are quite reasonable considering you get five ocean dives, professional guidance, and a recognized certification. For beginners wanting a comprehensive introduction, it’s good value, especially because the small group setting enhances the safety and learning experience.
