Half day boat diving experience for beginners in Kos Greece

Pserimos gives this beginner scuba trip its appeal: a quiet, sheltered bay, clear water, gentle depth, and a boat day that feels more personal than a large island cruise. You learn the basics on the way from Kos, then enter the water with two PADI instructors for every group of four or five.

I especially like the shallow setting and the choice after your first 20 to 25-minute underwater session. You can pay €45 for a second session, snorkel, swim, or simply stretch out on the sundeck. The main consideration is the early start, plus the rule against flying within 24 hours after scuba activity.

Key points at a glance

• Maximum depth of 5 metres: The sheltered bay around Pserimos gets deeper very slowly, which helps first-timers stay calm.
• Small groups in the water: You are placed with four or five people and two instructors, allowing close supervision.
• A full boat morning: The boat leaves Kos at about 8:30 am and returns around 2:30 pm.
• Snorkelling comes included: You can take part even if you prefer not to use the scuba equipment.
• Second session costs €45: After a break, you can repeat the underwater activity or relax on board.
• Strict safety limits apply: You must be at least 12 years old and 140 centimetres tall, and you should not fly within 24 hours.

Why Pserimos works so well for a first scuba session

The first underwater experience can be exciting and slightly awkward. You are learning to breathe through a regulator, manage unfamiliar equipment, and follow hand signals, all while trying to notice fish. Pserimos helps by keeping the setting simple.

The boat stays within a bay protected by rocky outcrops on both sides. The bottom slopes gently, reaching no more than 5 metres. That is shallow by scuba standards, but it is enough to give you a real sense of moving beneath the surface without the pressure of a deep descent.

The clear water also matters. You can barely feel the depth increase, and the visibility makes it easier to watch your instructor and look around at the same time. For a beginner, that combination is more useful than a dramatic deep-water site.

You should not expect a long technical scuba expedition. This is an introductory session designed to make you comfortable, show you the basics, and give you a controlled look at marine life. That focus makes it suitable for a first attempt, rather than for certified participants seeking challenging underwater terrain.

The 8:30 am departure from Kos

You meet at the Port of Kos at 8:30 am. The activity ends back at the same port at about 2:30 pm, so you should set aside most of the morning and early afternoon.

The early departure is practical. The boat has time to reach Pserimos, complete the instruction, allow for a break, and offer the optional second session without turning the day into a rush. It also leaves you with part of the afternoon free after returning to Kos.

Bring anything you expect to need for several hours at sea, since snacks are not included. Scuba equipment and snorkelling equipment are supplied, so you do not need to arrange tanks, masks, fins, or the main gear separately.

The booking uses a mobile ticket and the activity is offered in English. The maximum group size is 10 people, though the water portion is split into groups of four or five. That is an important distinction. You may share the boat with up to nine other people, but the instructors do not place the entire group underwater at once.

A safety briefing before you enter the water

Instruction begins during the journey. You receive a detailed explanation of the equipment, the planned activity, and the safety rules. For a beginner, this time is valuable because it lets you ask questions before you are floating in the bay.

The strongest part of the setup is the instructor ratio. Each group of four or five is accompanied by two PADI instructors. You still need to listen carefully and follow directions, but you are not left trying to work things out alone.

The approach is especially helpful if you have tried scuba before and felt uncomfortable. One person who had struggled previously found that simple explanations and a snorkelling period first made the transition easier. You can use that same strategy: start by getting used to the water and mask, then move to the breathing equipment when you feel ready.

The equipment briefing also gives you a chance to understand what each part does. That may sound basic, but clear preparation often determines how much you enjoy the underwater portion. If you begin tense, you may spend the whole session managing nerves. If you understand the gear, you can pay attention to the fish and the bay.

Snorkelling first can make the water feel easier

Snorkelling equipment is included, and the schedule allows you to enjoy the water beyond the scuba session. This is useful for companions who do not want to use scuba equipment, as well as for beginners who want a gentle introduction before trying it.

A family can split its time without anyone being left out. One parent and child might take the scuba session while another family member snorkels from the boat. A previous family outing included a younger participant who snorkelled while other family members used the equipment.

The information provided says non-swimmers are not accepted, so you should treat basic swimming ability as necessary and confirm any uncertainty before booking. The boat team watches over people using the water, but supervision does not replace being comfortable in the sea.

Snorkelling also gives you a useful preview of the bay. You can see how clear the water is, check how you feel with a mask, and get used to the temperature and movement before the main session. For nervous beginners, that short adjustment period can make a big difference.

What the 20 to 25-minute underwater session feels like

Once your group is ready, the instructors guide you through the sheltered bay. The maximum depth is 5 metres, and the bottom slopes gradually rather than dropping away suddenly.

The session lasts about 20 to 25 minutes. That is enough time to practise breathing, follow instructions, move around the bay, and stop to look at marine life. You also have the chance to take underwater photos during the outing.

The clear water is the star here. Fish are close enough to notice without needing a strenuous swim, and the shallow setting keeps the experience approachable. One especially memorable part for some participants is seeing the fish at close range. The bay is not presented as a captive display, so the appeal comes from observing marine life in its natural setting.

Do not expect the same scale as a full certification course. This is a supervised introduction, not a qualification. You are trying scuba with professional guidance, not completing the classroom, pool, and open-water requirements of a PADI certification.

That distinction is helpful when judging the price and the result. If you want to discover if scuba suits you, the session gives you a meaningful test. If you already hold certification and want several substantial underwater routes, you may find the shallow format limited.

The break and optional second session

After the first session, you have time to relax. The second underwater session costs €45 per person and is not included in the main price.

I think this option is worth considering for first-timers. The first session is often spent remembering how to breathe and communicate. By the second attempt, you understand the equipment and can spend more time looking around. One participant who tried the extra session described it as both more enjoyable and confidence-building.

You do not have to pay for it. The boat also gives you the choice to snorkel, swim, or rest on the sundeck. That flexibility improves the value for mixed groups. A keen beginner can continue, while a companion who has had enough sun or water can take a quiet break.

If you are unsure, wait until after the first session before deciding. You will know how comfortable you feel, how much energy you have left, and whether another 20 to 25 minutes in the water sounds appealing.

What is included, and what costs extra

The listed price is $126.15 per person. That covers the half-day boat outing, scuba equipment, and snorkelling equipment, along with instruction and supervision from the PADI team.

The value depends on what you want from a beginner activity. For someone starting from zero, having the equipment, safety briefing, boat transport to Pserimos, and close instructor supervision arranged in one booking is convenient. You are paying for a guided introduction rather than simply hiring gear.

The price does not include food. Bring snacks if you need something between the morning departure and the return to Kos.

The second underwater session costs €45 per person. Photos and videos are available for €25 on a USB stick. These extras are optional, so you can keep the base cost under control. If capturing the experience matters to you, decide in advance if the additional charge fits your budget.

The experience receives a 5 out of 5 rating from 29 published ratings, with 100 percent recommending it. The most consistent praise focuses on the crew, clear instruction, personal attention, and the beauty of the water. That does not guarantee every participant will feel relaxed, but it points to the parts of the outing that are most likely to shape your day.

Who should book this Kos boat experience

This trip suits you if:

• You have never tried scuba and want a supervised introduction.
• You are nervous about depth and prefer a sheltered bay with a maximum of 5 metres.
• You want a small-group setting rather than a crowded boat operation.
• You are travelling with people who prefer snorkelling or swimming.
• You want the option of a second session without committing to it before the first.
• You would like to test your interest before signing up for a full PADI course.

It also works well for families, but check the age and height rules carefully. Participants must be at least 12 years old and 140 centimetres tall. One published account describes a 10-year-old taking part, but the stated booking requirement says not younger than 12, so you should rely on the official rule and confirm before paying.

The trip is less suitable if you want a deep site, a long underwater route, or an advanced technical challenge. It is also a poor match for anyone planning to fly soon after the activity.

Medical conditions need attention too. The booking information specifically flags people with medical conditions, so ask the provider before confirming if this applies to you. Do not treat an online booking as medical clearance.

Practical limits that affect your planning

The activity depends on good weather. If conditions force a cancellation, you are offered another date or a full refund. The same applies if the minimum number of participants is not reached.

You can cancel for a full refund up to 24 hours before the 8:30 am start. Changes or cancellations made inside that period are not accepted and are not refunded. I would avoid placing this trip on the final morning of your holiday, since bad weather or a schedule change could remove your only chance to go.

The flying rule is easy to overlook. You should not fly within 24 hours after the scuba activity. If your return flight leaves the next day, place this outing earlier in your Kos schedule.

A moderate level of physical fitness is expected. You need to manage the boat day, equipment, water entry, and time in the sea. Service animals are allowed, and the port is near public transportation, but the supplied information does not give detailed access arrangements for the boat itself. If mobility support matters to you, contact Liamis Dive Centre before booking.

Final verdict: is it worth booking?

I would book this if your goal is to try scuba in a calm, well-supervised setting rather than earn a certificate or chase a challenging site. The sheltered Pserimos bay, shallow water, small in-water groups, and two-instructor setup give beginners a sensible introduction.

The price is fair for a half-day boat outing with equipment and instruction included, though the extras add up if you choose the second session and USB photos. I like that the second session is optional, because you can make the decision after experiencing the first.

Book it for the clear water, careful instruction, and chance to share a sea day with snorkellers. Skip it if you cannot swim comfortably, have a medical concern that has not been cleared, need to fly within 24 hours, or want advanced scuba. For a first taste of Kos beneath the surface, this is a strong choice.
