First-time scuba in Kos is surprisingly calm. I love the PADI instructors who coach you through every step, and the 5-meter max bay that keeps your first underwater time manageable. The one thing to plan for is that this package includes only one underwater session, and a second one costs extra in cash.

You board the Apollon, a 25-meter boat with a shaded deck plus a roomy sun area, and you’re out on the water early. After the cruise to Pserimos, you also get time for swimming and snorkeling, so it’s not just about the first lesson—it’s a proper half-day sea outing in the Dodecanese.

Key things I’d bank on before you go

• Max depth of 5 meters: you won’t be fighting depth on your first attempt
• Small groups (4/5 people) with 2 instructors: plenty of eyes on you
• 20–25 minutes underwater with close coaching and safety focus
• Pserimos Town time for snorkel and swim even if you stick to the included session
• Equipment and snorkeling gear are included with the base price
• Photo/video add-ons are optional, paid separately on the day

Kos to Pserimos: why the sheltered 5-meter setup helps first-timers

This Kos experience is built for people who want to try scuba without feeling thrown in at the deep end. Your group stays inside a protected bay near Pserimos, with rocky sides that calm things down. The plan is a gentle depth increase, topping out at about 5 meters, and you’re likely to feel how clear the water is more than the depth itself.

That matters for your brain. First-time scuba is partly equipment and partly nerves. If you’re not dealing with strong currents or changing conditions, you can focus on breathing and staying relaxed. The course also keeps you inside a controlled environment, which is why the safety talk and instructor supervision feel like the real center of the day—not the water itself.

Also, there’s a nice “learning by doing” rhythm here. You’re not just listening. You get a site briefing, equipment checks, then a guided underwater window with your instructors right there to help you stay comfortable.

From Liamis base to Pserimos Town: the 6-hour flow

This is a classic half-day format, with enough structure to keep you from feeling rushed, but not so much time that it drags.

Here’s how the day typically moves:

• Start at the Liamis base and board the Apollon in time to leave at about 08:30
• 45 minutes on a sightseeing cruise toward Pserimos
• A safety and site briefing (expect around 15–20 minutes, depending on the timing of the boat and group)
• You reach Pserimos Town, then you get your underwater session (about 30 minutes at the site, with 20–25 minutes actually underwater under instructor watch)
• After you surface, you get a relaxing break
• Then you choose: do a second underwater session for an extra 45€ paid cash on the boat, or stay above water and enjoy swimming and snorkeling
• You’re back in Kos around 14:30

A couple of practical notes that make this smoother:

• You’re split into groups of 4/5 people with 2 instructors, so you’re not waiting around for someone else to finish.
• You’re guided through the equipment use as part of the safety prep, which helps you get your bearings fast before you’re in the water.

The Apollon boat in Kos: shaded shade, sun time, and how to dress

The boat is part of why this feels like a relaxed day instead of a stressful logistics exercise. It’s about 25 meters long, with a shaded deck (useful when the sun is bright) and a spacious sun deck if you want to dry off and watch the coastline.

During the cruise, you’re not just transporting to the activity. You’ll also have time to look out at the Greek islands and enjoy the trip. That’s especially nice because Pserimos is the kind of place where a calm morning pace fits.

What you should bring (this is your real “make the day easy” list):

• Swimwear, plus a towel you can use right after you’re out
• Sunscreen, sunglasses, and a hat
• Comfortable shoes and comfortable clothes for the boat ride
• If you tend to get cold on boats, bring a light layer
• Cash (important because the optional second underwater session is 45€ in cash)

Snacks and drinks are not included; you can buy them on the boat. If you hate decision-making in the moment, grab water and a snack before you get too far into the day.

Instructors and safety: why this course stays steady when nerves show up

The standout theme in the feedback is how the instructors handle real human reactions. One of the best signals you can look for with a first-time scuba course is whether the team can adapt when someone feels anxious. Here, the coaching is described as caring, patient, and understanding, including support for someone who had panic around breathing underwater.

That tells you something useful: the staff doesn’t just run a schedule; they manage comfort.

A few things that also reduce stress during the day:

• You have PADI instructors watching you throughout the underwater time
• You stay inside a bay with calm conditions
• You get a site briefing and equipment walkthrough before the session
• The group size stays small enough that you won’t feel lost

Before you go in the water, you’ll also fill out a medical statement. Scuba isn’t for everyone, and the rules here are clear: you need no serious health issues, you must be able to swim, and it’s not for people with pre-existing medical conditions. You also shouldn’t fly for 24 hours after your underwater session.

If you’re the kind of person who tends to get stressed by the unknown, this kind of structure is exactly what you want.

Marine life at easy depth: fish, clear water, and photo moments

One reason people fall in love with scuba is how fast the underwater world grabs your attention. With this course, you get that effect without the harder parts of technical depth or long exposure.

You’ll see abundant marine life in the area around Pserimos. During the boat ride and around the bay, the group stops to look at marine life and you can interact with fish while staying under instructor guidance. Then you get your underwater window, timed and supervised (20–25 minutes) with your instructors keeping watch.

Because the maximum depth is only about 5 meters, the learning curve is gentler. You’re not trying to solve depth problems. You’re practicing buoyancy, breathing, and staying calm. That’s why this setup is so good for first-timers: your attention can stay on the experience itself.

On top of that, you’ll have a chance for underwater photos during the session. You can add on a memory package later: the option listed is a USB memory stick (25€), and at least some recent groups reported getting photo/video files quickly via WeTransfer after the trip.

Pserimos Town time: snorkeling and swimming between sessions

Even if you don’t do the second underwater session, this day isn’t a “one-and-done” plan. After your first underwater window and a break, you’ll have time to enjoy swimming and snorkeling around Pserimos Town.

This is a smart way to round out the day:

• You get more water time without pressure
• Snorkeling lets you enjoy the sea-life viewing when you’re not managing scuba gear
• It’s also a good recovery buffer if you felt a little tense underwater and want to settle your breathing

Because snorkeling gear is included, you can keep it simple. Bring your towel and sunscreen, and give yourself a little time to warm up on the boat between water moments.

Price and value in Kos: what $123 covers, plus the real extras

At $123 per person for a 6-hour half-day, the big value is what’s included up front:

• Boat transfers and captain
• Scuba instructors
• Diving equipment (listed as included) and snorkeling gear
• A site briefing
• One underwater session in a small group, with supervision, max 5 meters, lasting 20–25 minutes

Then there are optional add-ons:

• A second underwater session for 45€ paid cash on the boat
• A photo/video memory package (listed as USB for 25€)

So the honest math is this: the base price gets you the full first-time experience with gear and instruction. If you think you’ll want more than one underwater window, plan on adding the extra 45€. If you’re the type who cares about documenting the day, budget the memory pack as well.

Also, this kind of structured beginner course tends to be worth it because you’re paying for safety management and coaching. You’re not just “buying access to water”; you’re paying for a team that keeps your first attempt controlled and comfortable.

Who should book this beginner scuba day (and who should skip it)

This is ideal if you:

• are 12+ (minimum age is 12)
• have no prior experience (not required)
• can swim
• want a small-group, guided first underwater experience with PADI instructors
• like the idea of pairing scuba practice with time on a Greek island for snorkeling and swimming

You should skip it if you:

• are under 12
• are not a swimmer
• have serious health issues or any pre-existing medical conditions that make scuba unsafe (you’ll be asked for a medical statement)

And if you’re planning flights soon, remember the “don’t fly” rule: 24 hours after your underwater session.

Should you book this Kos first-time scuba course?

Yes, if your main goal is a safe, guided first underwater experience with time to relax in between. I like that the course uses a protected bay and a 5-meter max depth, because that turns “first time” into something you can actually enjoy. The instructor style matters too: multiple recent bookings highlight patience and support for anxious beginners, not just technical instruction.

One decision point: because only one underwater session is included, think about whether you want the extra 45€ cash second session. If you feel like you’ll want more time in the water once you’re comfortable, you can plan for that from the start.

If you want a relaxed day on the water—boat ride, sea-life viewing, plus snorkeling time—this one makes a lot of sense.
