Half Day Snorkelling Experience with a dive boat in Kos Greece

Pserimos is the main attraction here: a small island setting, clear Greek water, and a morning built around snorkelling rather than racing through several stops. I like the unhurried time in the bay and the chance to see marine life such as octopus and moray eels. I also like the friendly, careful crew, especially Athina, who helps make the outing feel personal rather than rushed.

The main point to consider is that this is a shared boat for snorkellers and scuba participants. If you want a snorkelling-only trip with a long list of separate bays, this may feel too simple. If you prefer a calm morning with time to swim at your own pace, it is a strong value.

Key points at a glance

• Pserimos is the focus: You spend the morning around this nearby island rather than trying to squeeze several islands into one hurried route.
• Shared boat setup: The boat carries snorkellers and scuba participants, so the schedule is built for both groups.
• Equipment is included: You do not need to arrange your own mask, snorkel, or related gear.
• Wildlife can be rewarding: Octopus and moray eels have been seen in the bay.
• Small maximum group: The boat accepts up to 20 people, a more manageable size than a large party cruise.
• Early return: You meet at 8:00 am, depart around 8:30 to 9:00, and return to Kos at about 2:00 pm.

Why Pserimos makes a good half-day target

This outing keeps its sights on Pserimos, an island near Kos known here as the place for a morning of sea, sun, and snorkelling. That simple plan is its strength. You are not spending the whole day moving from one stop to the next, trying to remember which cove allowed five minutes in the water and which one allowed fifteen.

The schedule gives you roughly five and a half hours from the morning meeting time to your return. The boat leaves around 8:30 to 9:00 am and gets back to Kos at about 2:00 pm. Exact departure timing may vary within that window, so arrive ready for the 8:00 am meeting time at Liamis Dive Centre.

The setting also gives the trip a quieter feel than the popular multi-island cruises. You might find that the boat remains in one bay long enough for you to snorkel, rest, and get back in without watching the clock every few minutes. That matters if you are still finding your confidence in the water or simply want a gentle morning outdoors.

There is no claim here of a packed marine park or a parade of guaranteed sightings. The appeal is more honest: you get a chance to look beneath the surface in a Greek island setting, with the possibility of seeing interesting creatures. Octopus and moray eels have been spotted, which gives you something specific to watch for without promising that nature will perform on cue.

Meeting the Liamis crew at 8:00 am

The meeting point is Liamis Dive Centre on Akti Kountouriotou in Kos, at the Liamis boat. You should treat 8:00 am as the important time, even though the boat is expected to depart around 8:30 to 9:00. That gap likely allows the crew to organize equipment, welcome the group, and prepare the shared boat.

The staff provide the snorkelling equipment, so you can leave your own gear at home if you prefer. The practical benefit is simple: you do not need to buy or rent a mask and snorkel separately, and you avoid carrying bulky equipment through Kos.

The boat holds a maximum of 20 people. That is not a private charter, but it is a reasonable ceiling for a boat trip. You should expect a mixed group, with some people joining for snorkelling and others taking part in scuba activities. This arrangement is worth understanding before you book, since the boat and timing need to work for both groups.

The crew’s approach sounds particularly useful for first-time or less confident snorkellers. A briefing takes place on the way out, covering what you need to know and checking that people feel comfortable. The staff have also handed out travel sickness tablets on a windy day, something many people appreciated. You should not rely on that as a guaranteed service, but it shows the crew pays attention to comfort on the water.

The boat ride from Kos to Pserimos

The ride out is part of the morning, not just transportation to be endured. You leave Kos after the group has been organized, then head toward Pserimos for the water session. Since the trip depends on sea and weather conditions, the route and timing can change if conditions are poor.

A windy day can make any boat trip less pleasant, especially if you are prone to motion sickness. The early start may help, since the water and air can feel more comfortable in the morning, but the supplied information does not promise calm seas. If you know you are sensitive, prepare before boarding and tell the crew how you are feeling.

The shared boat format also means the ride may include activity related to the scuba groups. You are not booking a private snorkelling boat with a guide focused only on your party. For some people, that is a drawback. For others, it keeps the price down while still providing a proper boat outing to Pserimos.

The boat trip costs $65.06 per person. I see that as fair if you value the included equipment, the boat journey, the staff support, and several hours away from Kos. It is less attractive if you only want a brief swim close to town or if you expect food, a private guide, or several separate islands.

Snorkelling around Pserimos

The water session is the heart of the outing. You reach Pserimos, get into the sea, and spend time snorkelling and enjoying the sun. The information does not set out a fixed minute-by-minute schedule, which is useful in one way: the morning can respond to the sea, the group, and the conditions.

You should expect a practical safety briefing before or during the ride out. That gives you a chance to understand how the activity works and decide how comfortable you feel before entering the water. If you are new to snorkelling, pay attention to the briefing and ask for help rather than trying to copy the strongest swimmer in the group.

The bay can offer more than a quick look at empty rocks. Octopus and moray eels have been seen, so scan carefully around rocky areas and openings rather than only looking straight ahead. Keep your expectations sensible. Marine life is wild, and no creature is guaranteed on a particular morning.

The chance to relax between swims is one of the better features here. You are not being pushed from one photo stop to another. You can enjoy the sea and sun, then take a break on the boat before going back into the water if conditions and the crew’s schedule allow.

You should also remember that a bay shared with scuba participants may have a different rhythm from a snorkelling-only excursion. The crew must manage people entering and leaving the water, and you may spend some time waiting for the group. That is a small price for the boat access, but it is part of the experience.

What the shared scuba and snorkelling format means

This trip is designed for two kinds of participants. Snorkellers use the surface equipment and enjoy the bay, while scuba groups take part in their own underwater activity from the same boat. That makes the tour useful for friends or families who want to go out together even if not everyone wants the same kind of water activity.

The trade-off is focus. A snorkelling-only boat might spend all its time choosing shallow water, adjusting the pace for surface swimmers, and moving between locations that suit snorkelling. Here, the crew has to serve a mixed group. You may get less individual attention than on a private snorkelling lesson.

Still, the maximum of 20 people keeps the arrangement from becoming a huge party cruise. I would be more cautious if the group limit were much higher, since crowded boats can make equipment, entry points, and rest space awkward. At this size, the setup should feel more manageable, though it is still a shared outing.

The staff’s briefing is important because it helps bridge the difference between experienced water users and people who are new to the activity. The crew are described as informative, helpful, and friendly, with professional handling of the equipment. That combination matters more than a fancy boat when you are deciding if you feel safe in the water.

What to bring, and what not to expect

Snorkelling equipment is included, but snacks are not. Bring food for after the water session or for the ride back, along with anything else you need for a morning in the sun. The supplied information does not list meals or refreshments as part of the price, so do not count on buying breakfast on board.

A practical packing list would include:

• Water and snacks
• Sun protection
• A towel and dry clothes
• Any personal motion sickness treatment you normally use
• A mobile phone or camera that you can protect from water

The tour is offered in English. Service animals are allowed, and the meeting point is near public transportation. Most people can participate, but you should still consider your own comfort in the sea and tell the crew if you need help.

The early start affects how you plan the day. You will be back around 2:00 pm, leaving the afternoon free in Kos. That makes this easier to fit into a short stay than a full-day cruise. You can snorkel in the morning and still have time for lunch, a rest, or more sightseeing later.

Weather, cancellation, and practical value

This is a sea-based activity, so weather matters. If poor weather cancels the trip, you are offered a different date or a full refund. The same applies if the minimum number of participants is not reached, with the choice of another date or activity, or a full refund.

For your own plans, that means you should avoid placing an important flight, ferry, or fixed afternoon appointment too close to the return time. The expected return is around 2:00 pm, but boat conditions can affect timing.

Free cancellation is available if you cancel at least 24 hours before the start time. Cancellations or changes made within 24 hours are not refunded or accepted. The cut-off follows local Kos time, so check the timing carefully if you are booking from another time zone.

At $65.06, the value depends on what you want from a water day. The price includes the boat trip, snorkelling equipment, crew support, and access to Pserimos for a substantial part of the morning. It does not include snacks, a meal, or a private boat.

I would choose this over a packed multi-island cruise if your priority is calm water time and a smaller maximum group. I would look elsewhere if your priority is lunch on board, a private guide, or a long list of named stops.

Who will enjoy this Kos snorkelling trip

This outing suits you if you want a straightforward way to get on the water from Kos without committing to a full day. It is also a good fit if one person in your group wants scuba activity while others prefer surface snorkelling.

You may especially like it if you:

• Prefer a relaxed bay visit over a tightly timed island circuit
• Want equipment supplied
• Enjoy small-group boat trips, with a maximum of 20 people
• Are curious about spotting octopus or moray eels
• Need an activity that returns to Kos around 2:00 pm
• Appreciate a crew that explains the plan and checks comfort levels

I would hesitate if you dislike shared boats, need guaranteed calm water, or want a snorkelling-only itinerary. The trip also may not suit someone looking for food and drinks included, since snacks are specifically not part of the package.

Should you book the Liamis Pserimos trip?

Book it if you want a reasonably priced morning on the water, supplied snorkelling equipment, and enough time to enjoy Pserimos without the pressure of a packed island-hopping schedule. The friendly crew, safety briefing, and reports of octopus and moray eels add real appeal.

Skip it if the shared scuba and snorkelling format does not suit you, or if you expect a private trip with several distinct bays. For the right kind of day, this is a sensible Kos choice: simple, social, and focused on actually spending time in the sea.
