The best thing about this trip is control. You have a private speedboat for up to six people, so the day can feel personal rather than like a ferry ride with a timetable. Your skipper can point out quieter beaches, adjust the pace, and take you from Kos to Psérimos, Plati Island, and Therma Springs in six hours.

I like the free snorkeling gear and icebox, since both save space and fuss. I also like the hotel transfer from Kos Town and Psalidi, plus the freedom to play your own music through Bluetooth. The main catch is clear: fuel is not included, and neither are food, drinks, or towels, so ask how fuel is calculated before you commit.

Key details to know before you book

• Private boat for up to six: The price is $707 per group, not per person, which can make sense for a full group.
• Three different stops: You get beach time at Psérimos Vathi, a possible lunch stop in Psérimos village, snorkeling at Plati Island, and a warm-water stop at Therma Springs.
• Fast, new speedboat: The boat is described as brand new and fast, useful when you want to cover several coastal stops in one day.
• Snorkeling equipment included: Masks and flippers are provided, though you should bring your own towel.
• Hotel pickup has limits: Free transfer is available from Kos Town hotels and the Psalidi area, or you can drive to the meeting point.
• Weather controls the plan: Strong winds and high waves can lead to a changed date, cancellation, or a calmer alternative destination.

Why a private Kos boat trip can be worth the price

At $707 for a group of up to six, the arithmetic matters. Six people sharing the base price would pay about $118 each before fuel, food, and drinks. A couple would carry the full cost between two people, so this trip makes the most sense for a family or friend group that wants a boat day without sharing the vessel with strangers.

The private setup is the real value here. You are not simply buying transport between islands. You are paying for room to set the mood, choose how long to swim, and ask the skipper about quieter beaches. The supplied information does not promise a fixed amount of time at each stop, so discuss the preferred balance before leaving Kos.

The speedboat also helps the itinerary work. Psérimos, Plati Island, and Therma Springs are separate stops, and a six-hour trip needs efficient travel. A fast boat gives you more time on the water and at the beaches than a slower craft might, although speed can mean a bumpier ride when the sea is unsettled.

There is one financial detail you should not brush aside. Fuel is excluded. Ask the operator whether it is charged as a fixed amount or based on actual use, and ask when payment is due. The advertised price is easier to judge once you know the final total.

Leaving Kos with your own small-group rhythm

Pickup is free from hotels in Kos Town and the Psalidi hotel area. You can also come by car, or meet at the central bus station in Kos Town if that arrangement suits you. Confirm the pickup point and time when booking, since the listed six-hour duration does not specify one universal departure time.

A private boat gives you a more relaxed start than a large group excursion. You do not need to wait for a long list of other passengers, and you can bring the food and drinks you want for the day. Still, pack with care. The boat includes an icebox, but the operator does not provide drinks or meals.

I would bring water, simple food, sunscreen, a hat, a T-shirt, a camera, and a towel. The advice to bring a T-shirt is especially practical for a long day under the Greek sun, when a little cover can make the ride home more comfortable.

Your skipper speaks English and handles the boat. No individual skipper name is provided, so if a named guide matters to you, request that information before booking. The skipper is also the person to ask about sea conditions, swimming time, and the best order for the stops.

Psérimos Vathi beach: a quiet first swim

The first destination is Psérimos Vathi beach. The appeal is simple: soft sand, clear water, and time to swim or sit in the sun without rushing straight into a packed schedule.

This is the kind of stop that sets the tone for the day. You can get into the water, dry off, take photographs, or simply enjoy the view from the shore. Since the outing is private, you can tell the skipper if you want a longer beach pause or would rather keep moving toward the next stop.

Do not expect a full-service beach day from the details provided. There is no mention of sunbeds, umbrellas, changing rooms, or a beach bar. Bring your own towel, sunscreen, and drinking water, and keep your expectations focused on a natural swimming stop rather than a resort facility.

The word Vathi refers to the beach named in the itinerary, but the exact facilities and time available there are not specified. That is not a problem if you want sea and sand, but it matters if your group needs regular shade or a formal place to change.

Psérimos village and an optional Greek lunch

After the beach, the boat heads to Psérimos village. The stated plan includes a chance to eat traditional Greek food, with fresh seafood and local specialties, but lunch is optional and not included in the price.

I like this part because it breaks up the swimming. A small seaside village offers a different experience from a boat-only itinerary, and a meal can turn the outing into a fuller island visit. You can sit down, eat at your own pace, and take in the quiet setting before returning to the water.

Bring this up with your skipper early. The supplied details do not name a restaurant, set a menu, or state how long lunch lasts. If you want seafood, have dietary needs, or prefer to bring your own meal, ask what is practical before the boat leaves Kos.

The optional lunch also gives you a way to control the budget. Food and drinks are not included, so you can order locally or pack provisions in the icebox. Just remember that a private boat price does not cover the cost of eating ashore.

Plati Island and the included snorkeling gear

Plati Island is the snorkeling stop. Masks and flippers are included, and the clear water is presented as a good place to see fish and underwater formations. For many people, this will be the most active part of the day.

You do not need to rent equipment separately, which is a useful saving and one less errand before departure. Check the fit of your mask and fins before entering the water. If you already own a favorite mask, you may still prefer to bring it, but the operator supplies basic gear.

The exact snorkeling location, water depth, and time in the water are not specified. Ask about those details during the briefing, especially if people in your group are inexperienced swimmers. The skipper can also explain where to enter the water and how to return safely to the boat.

This stop is about seeing what lies below the surface, not taking a formal marine tour. You may see colorful fish and underwater formations, but visibility and sea conditions can change. Bring a camera only if it is properly waterproofed, and do not count on towels being available afterward.

Therma Springs: a warm finish to the day

The final stop is Therma hot Springs, where you can relax in warm water. After a beach stop and snorkeling, the change of pace is welcome. This is less about activity and more about sitting still for a while.

Therma Springs are a practical choice for the end of a boat trip because you can finish with an easy swim rather than another demanding stop. The warm water may feel especially pleasant after time in the sea, though the experience can vary with weather and water conditions.

The supplied information does not provide details about changing areas, entry conditions, or how long you stay. Bring a towel and a dry T-shirt, since both are specifically left to you. Sunscreen is also important for the rest of the journey, even if the springs become the day’s final main stop.

Ask your skipper about the safest access point and current sea conditions. Strong winds or high waves may mean changing the destination or the order of the stops. The operator says safety and comfort come first, so a substitute stop may be the sensible choice on a rough day.

The speedboat, music, and comfort details

The boat is described as new and fast, with Bluetooth music available. That makes the ride more personal. You can play a familiar playlist instead of relying on a tour guide’s soundtrack, but keep the volume reasonable so you can still hear the skipper’s instructions.

A speedboat is not the same as a slow day cruiser. It gets you across the water efficiently, but you may feel more movement, especially if the sea is choppy. Anyone prone to seasickness should think carefully about the boat type and bring whatever personal remedy they normally use. The supplied information does not list a shaded cabin or toilet, so ask about those facilities if they affect your comfort.

The icebox is a small but useful inclusion. Fill it with bottled water and food before departure, since drinks and meals are not supplied. Pack items that can handle movement on a boat, and keep cameras and phones protected from spray.

There is no mention of towels, fuel, or onboard catering in the price. Those exclusions are normal enough for a private boat rental, but they shape the total cost and preparation. The more organized you are before leaving Kos, the less time you spend searching for supplies.

Weather, timing, and who will enjoy this most

Six hours is enough for a varied outing, but not enough for unlimited time at every stop. You should decide what matters most to your group: a long beach break, lunch in Psérimos village, snorkeling, or a leisurely visit to Therma Springs.

The skipper may suggest a different route in strong wind or high waves. The trip can be rescheduled, moved to another date, canceled, or redirected to calmer water. This flexibility protects the experience, but it means you should keep some room in your holiday schedule if possible.

This trip suits you best if you:

• Want a private boat rather than a shared excursion
• Have a group of up to six people to share the cost
• Like combining swimming, a village stop, snorkeling, and hot springs
• Prefer to bring your own food, drinks, and music
• Are comfortable with a fast boat and changing plans in poor weather

It may be less suitable if you want a fully catered day, guaranteed fuel-inclusive pricing, extensive guided commentary, or a fixed schedule at each location. It is also not suitable for pregnant women, according to the activity information.

Booking details that affect the decision

The operator offers free cancellation up to 24 hours before the trip for a full refund. You can also reserve now and pay later, which helps if your Kos plans are still shifting. Check availability for the start time, since the activity does not provide one fixed departure hour.

The language listed is English, and the group type is private. Hotel transfers are free from Kos Town and Psalidi hotels, while other pickup arrangements should be confirmed in advance. If you are staying outside those areas, you may need to come to the central bus station or drive to the meeting point.

Before you pay, I would confirm four things:

• The expected fuel charge
• The exact pickup point and departure time
• The planned time at each stop
• The lunch arrangement in Psérimos village

Those questions are not nitpicking. They tell you the final price, the shape of the day, and how much freedom you really have.

Should you book this Kos to Psérimos trip?

I would book this private boat day for a group that values privacy and wants several different experiences in one outing. The combination of Psérimos beach, Plati snorkeling, and Therma Springs gives you more variety than a simple beach transfer, while the included gear and hotel pickup reduce some of the usual hassle.

I would hesitate if you are a couple watching every euro, since the $707 base price becomes harder to justify before fuel and meals. I would also look elsewhere if you need a highly structured tour with a published timetable and every expense included.

For six people who want their own boat, the price can be reasonable. Ask about fuel, pack your own supplies, and accept that weather may change the route. If those conditions suit you, this is a flexible, water-focused day from Kos with a good mix of swimming, local food, snorkeling, and warm springs.
