Best of Milos and Poliegos Catamaran snorkelling Cruise with BBQ

Milos is best seen from the water, where white cliffs, old mines, sea caves, and beaches cut off from the road unfold one after another. This full-day POLCO Sailing cruise reaches places you simply cannot visit by car, including Poliegos’ Blue Lagoon and the caves of Kleftiko. The Lagoon 440 catamaran gives you room to stretch out, rather than trapping you on a small boat.

I especially like the generous food service, from homemade Greek tapas and fruit to the BBQ lunch, and I like that the crew takes underwater GoPro photos for you. The crew, including names such as Captain Yannis, Dina, Flo, Elena, and Andreas on different departures, also gets high marks for personal service. The tradeoff is the weather: strong wind can force the captain to change the route, and nine hours at sea may feel long if you want a quick beach outing.

The day at a glance

• A full southern and western Milos route: See Kleftiko, Gerakas, Kalogries, Tsigrado, Cape Vani, the old sulfur mines, and more when sea conditions allow.
• Poliegos’ Galazia Nera: Swim at the Blue Lagoon beside Greece’s largest uninhabited island.
• A spacious Lagoon 440: The boat is 44 feet long, with indoor shelter and outdoor areas for sun and fresh air.
• Greek food served throughout the day: Expect tapas, fruit, salads, snacks, drinks, and a BBQ lunch with vegan choices.
• Photos included: The crew uses GoPro and underwater photography, then sends a set of images by email.
• A small-group feel: The experience is promoted for around 20 people, with a formal maximum of 22.

Why seeing Milos by catamaran makes sense

Milos has plenty of beaches you can reach by road, but some of its best coves face open water and have no practical land access. Gerakas, Kleftiko, Kalogries, and several small swimming spots are much easier from a boat. You avoid scrambling down ropes or ladders, and you get to see the island’s cliffs from the angle that makes them most striking.

This is not a silent sailing trip. Music plays, people swim and chat, and the crew serves food and drinks all day. Still, the mood is generally relaxed rather than built around loud partying. That distinction matters if you want a social day at sea without booking a floating nightclub.

The catamaran format also helps. A 44-foot Lagoon 440 is not a private yacht, but it gives you more usable space than a narrow single-hull boat. You can sit outside in the sun, find shelter inside when the wind picks up, and move around between swim stops. The boat is advertised with a cap of 20 people, while the formal maximum is 22, so check the final group size if personal space is a major concern.

Meeting in Adamantas at 9:00 a.m.

You meet at the listed point in Adamantas, written as PCFW+PJ Adamantas, and the cruise returns there at the end of the day. Hotel transfers are not included, so you need to reach the port yourself. One practical point: parking near the port can take time, particularly when several boats leave around the same hour. Give yourself a little margin rather than arriving at 8:59.

Bring a swimsuit, towel, sunscreen, and a light layer. Towels and swimsuits are not supplied. A hoodie is useful for the ride home, when wind and cooler air can make an otherwise hot day feel chilly. Apply sunscreen before boarding and keep reapplying, since you will spend many hours around bright water.

The crew provides masks, snorkeling equipment, lifejackets, swimming aids, bottled water, soft drinks, and paddleboards. Wi-Fi is also included, though a day like this is a good excuse to put your phone down for stretches at a time.

Poliegos and the Galazia Nera Blue Lagoon

One of the strongest reasons to choose this longer cruise is the visit to Poliegos, Greece’s largest uninhabited island. The main stop is Galazia Nera, known as the Blue Lagoon. The water here is noted for its exceptional clarity and bright color, and the stop lasts about 40 minutes.

You will swim and have a late breakfast here. The meal is part of the ongoing food service, so do not expect a formal restaurant-style breakfast at a dock. Instead, the crew brings out homemade Greek foods, fruit, salads, and drinks during the day.

Poliegos feels different from the built-up parts of Milos. There are no town streets or beach facilities to distract you. The point is the clean water, pale rock, and time in the sea. If swimming is your main goal, this stop alone gives the full-day cruise a strong argument over shorter outings.

The visit depends on wind and sea conditions. A captain may reroute to a safer cove, especially when the water becomes rough. That means the exact order, or even the exact selection of stops, is not guaranteed.

Seagull Islands, sulfur mines, and the old Milos shoreline

Along the route, the boat passes the Seagull Islands, an unusual geological formation made of six-sided tubes created under great pressure. They are a quick sightseeing point rather than a long stop, but they add useful variety to a day otherwise centered on beaches and swimming.

The old sulfur mines sit on the southeast side of Milos. They were used until 1956 and are now abandoned. From the water, you see a remote industrial site that would be difficult to reach in the same way from land. The crew explains the story as the boat passes, giving the scenery some context instead of treating every stop as just another photo background.

The itinerary also includes a pass by Cape Vani, an old manganese and iron mine dating to the 19th century. Its large opening reaches down toward the sea, with sharply cut rock and black and ruby-red horizontal layers. You do not stop for a land visit, but the view is worthwhile from the boat.

You also pass the biggest cave in Milos. These short viewing sections break up the swimming schedule and help you understand the island’s volcanic geology. If you prefer constant time in the water, they may feel like interruptions. If you want a broad look at Milos, they make the day more varied.

Gerakas and Tsigrado from the sea

Gerakas is one of Milos’ famous boat-access beaches. The cove is framed by large perlite sand slides and clear emerald water. The planned swimming stop lasts about 30 minutes, enough for a quick swim and some photos without using up the entire afternoon.

The stop works well for people who want to see several different settings in one day. Gerakas has a more enclosed, sculpted feel than the open coast, and the pale slopes make a sharp contrast with the water. You are not simply repeating the same beach experience at every stop.

The boat passes Tsigrado, another well-known beach. Reaching it by land involves ladders and ropes, while the catamaran lets you photograph it from the water without that awkward descent. This is a pass-by rather than a long shore stop, so set your expectations accordingly.

Kleftiko, the main event

Kleftiko is the centerpiece of the route. Its name refers to a place used by pirates as a hideout, but the real attraction today is the maze of pale and gray rock, caves, and underwater passages. The cliffs rise directly from the sea, creating the kind of setting that makes a boat trip around Milos feel worthwhile.

The catamaran stays for a little more than an hour. You can swim, snorkel through clear water, explore around the caves, and try the stand-up paddleboard. The crew supplies masks and gives basic advice on how to explore the area safely.

This is also where the BBQ lunch is served. The food includes vegan options, alcoholic and nonalcoholic drinks, and additional snacks. The broader menu includes Greek tapas, salads, fruit, and local drinks such as beer, white wine, and ouzo. The strongest praise for the cruise centers on the food, with several accounts describing it as fresh, abundant, and prepared aboard the boat.

Do not expect a restaurant kitchen or a long, quiet meal with a view from a private table. You are eating as part of a busy swim stop, with people moving between the deck and the water. That is part of the fun, but it also explains why one account wished for less time eating and more time swimming.

The crew uses GoPro equipment here, including underwater shots. A set of photographs is sent by email later. This is a useful extra, especially if you do not want to risk your own phone in salt water. It also adds value for people who care about good action pictures rather than only taking selfies from the deck.

Kalogries and the return toward Cape Vani

Kalogries is an inaccessible bay on the west side of Milos with turquoise water and two small beaches. The stop lasts about 30 minutes, giving you time to jump from the boat, swim, snorkel, and have more snacks and drinks.

By this point, the day has settled into a comfortable pattern: cruise, swim, eat, listen to the crew’s stories, then move on. That rhythm suits people who want a complete day on the water. It may be tiring if you prefer to stay ashore and control your own schedule.

The final scenic sections include the largest cave in Milos and Cape Vani. The crew points out the mining remains and the unusual rock colors while you take photos. These sights are especially worthwhile when the sun catches the red and black layers of the cape, though the view naturally changes with cloud, wind, and the angle of the boat.

Food, drinks, and the crew’s role

Food is not an afterthought here. You get homemade Greek tapas, salads, fruit, snacks, breakfast items, and a BBQ lunch. Drinks include bottled water, soda, beer, local white wine, and ouzo. Vegan choices are available at lunch.

The service style is a big part of the experience. Crew members such as Dina, Flo, Elena, Andreas, Panos, and the various captains are described as warm, attentive, and willing to help with swimming, seasickness, and general comfort. Names and crew combinations can change by departure, so do not book expecting one particular person unless the operator confirms it.

The boat is not presented as a party cruise. Music plays, but it is generally kept at a reasonable level. One nice touch is that the crew may ask about favorite songs and build a playlist around the people on board. That makes the day feel more personal without turning it into a staged entertainment show.

If you are prone to seasickness, take the possibility seriously. A rough day can still be enjoyable when the captain changes course and the crew pays attention, but no boat can make choppy water feel calm. The crew has offered practical help such as chewing gum to people feeling unwell, though you should bring any medication you normally use.

Weather, route changes, and comfort

The captain has the final say on the route. Strong wind can prevent the boat from reaching the southern part of the island or Poliegos, and the itinerary may be changed for safety and comfort. That is not a minor detail in the Cyclades. The same wind that makes the sea feel exhilarating can also remove several planned swimming stops.

A changed route does not necessarily mean a poor day. Captains have redirected boats to safer beaches and still provided swimming, food, and scenery. But you should book this as a full day on the water, not as a guaranteed checklist of every named beach.

The catamaran has indoor and outdoor areas, which helps when conditions shift. On a calm day, you can spread out and enjoy the sun. On a windy day, you will appreciate somewhere to get out of the spray. The boat’s size helps, but it does not eliminate movement, so this is not ideal for anyone who becomes very uncomfortable at sea.

Is $241.86 a fair price?

At $241.86 per person, this is not the cheapest way to see a Milos beach. The value comes from what is bundled into the nine-hour outing: a full-day route, boat access to remote coves, snorkeling gear, paddleboards, breakfast-style food, Greek tapas, a BBQ lunch, open-bar drinks, Wi-Fi, and underwater photos.

You also avoid paying separately for equipment, meals, and drinks during the day. If you would otherwise book a boat trip plus lunch and several beach transfers, the price becomes easier to justify. The included images are a useful bonus, especially for a family or couple who want photographs of the swimming portions.

The price is harder to justify if you dislike group outings, rarely swim, or mainly want to see Kleftiko for an hour. In that case, a shorter or private charter might fit better, though the supplied information does not give comparison prices for those choices.

Who should book this cruise?

I would choose this for a first substantial visit to Milos, especially if you want to combine scenery, swimming, food, and history in one day. Families with older children can make good use of the swimming, paddleboard, and onboard space. Couples, solo visitors, and small friend groups also benefit from the social setup without being pushed into a loud party atmosphere.

It suits confident swimmers and people comfortable spending most of a day at sea. Bring a layer if you tend to get cold, and plan for wind. If you need a tightly fixed schedule, guaranteed calm water, or a quiet private boat, this is not the right fit.

Cancellation is free up to 24 hours before the 9:00 a.m. start. If poor weather cancels the trip, you are offered another date or a full refund. The same applies if the minimum number of participants is not reached.

My call: a strong full-day choice for Milos

I would book this cruise if you have one open day and want to reach the beaches and caves that make Milos special from the sea. Kleftiko and Galazia Nera are the major reasons to go, while the food, drinks, photos, and attentive crew make the long day easier and more enjoyable.

Go in with the right expectations: the captain may alter the route, the sea can be rough, and the boat can carry up to 22 people. If those points work for you, the mix of remote coves, Greek food, snorkeling, and practical onboard service makes the $241.86 fare reasonable for a full day around Milos.
