Thinking about getting scuba certified in the Florida Keys? The PADI Open Water Diver course in Key Largo offers a solid way to start your underwater adventures. It’s a popular choice for travelers wanting a mix of online learning and real-world practice in a beautiful setting.
What we really like about this course is its flexibility—you can do the theoretical part at your own pace—and the fact that it includes all equipment and fees, so there are no surprises. On the flip side, the total cost sits around $710, which is decent but not the cheapest option out there.
This experience is ideal if you’re eager to earn a globally recognized certification that lasts a lifetime. It’s also well-suited for those who want a manageable, well-structured schedule without long, drawn-out courses. If you’re comfortable with some upfront investment and looking to explore marine life in the Keys, this one could be a good fit.

What to Expect from the Course

We think this course strikes a good balance for those new to scuba diving. The first step is engaging with online coursework. You’ll learn the theory at your own pace using PADI’s interactive system, complete with videos, quizzes, and practice questions. It’s a smart way to absorb the information before jumping into the water.
Once you’re comfortable with the basics, you’ll move into pool training. This full day of hands-on practice helps you master key skills like breathing, buoyancy, and emergency procedures in a controlled environment. The small group setting means instructors can give you plenty of individual attention, which is often appreciated by first-timers.
The highlight is definitely the open-water dives. They take place over two days at reef sites, giving you the chance to see some of the stunning marine life Florida is famous for. If weather conditions aren’t ideal, the provider offers a lagoon alternative, which keeps the schedule flexible but might feel slightly less adventurous.

The Schedule: How It Breaks Down
The course typically runs over three days, often in the mornings, which is convenient for those wanting to explore further or relax in the afternoons. You’ll start with the online class—an activity that you can do anytime within 12 months of registering, giving you plenty of flexibility.
The following day is dedicated to pool training, where the instructor will guide you through essential skills. Many reviews mention this day as a confidence builder—”the instructor was patient and thorough,” one reviewer shared, highlighting the importance of small group sizes.
The last two days are reserved for ocean dives. You’ll visit different reef sites, with each dive designed to practice what you’ve learned. Participants have enjoyed seeing colorful fish, coral formations, and even larger marine creatures. The dives are spread out to allow you to focus on each one, and weather conditions are taken seriously, with the lagoon option available if needed.
What’s Included: No Hidden Costs

The price of approximately $710 per person covers a lot. You get online coursework and materials, which is a huge plus because you can start learning before even arriving. The pool training session is included, along with gear rental—so, no need to buy or bring your own gear unless you want to.
All entry and charter fees are covered, meaning you won’t face additional costs once on the water. Completing the course results in your PADI certification, a credential recognized worldwide, opening up many more dive opportunities.
However, there are some extras to consider. You’ll need to rent or buy your mask, snorkel, and fins if you don’t already own them. Also, a logbook is required for class, and non-PADI eLearning might cost an extra $60 if you opt for a referral or additional certification.
The Experience: What You’ll Feel and See
Many past participants describe the experience as both fun and educational. The small group setting makes a difference—”having only four people meant I got personalized tips and felt more confident,” one reviewer said.
The ocean dives are often the highlight, with vivid coral and schools of fish making for stunning underwater scenery. The instructor’s guidance helps reduce anxiety, especially for newcomers, so you’ll likely feel comfortable exploring the reef after just a day or two of training.
Weather can impact the schedule—some reviewers mention that ocean conditions can vary, but the lagoon alternative helps ensure the dives still happen. The clarity of the water in Key Largo is generally good, offering excellent visibility for beginners.
