Best of Milos and Poliegos Catamaran snorkelling Cruise with BBQ

The best reason to book this cruise is simple: many of Milos’ finest swimming spots are reachable only by boat. From Poliegos’ fluorescent Blue Lagoon to the caves and white rock at Kleftiko, you spend the day seeing the island from its most dramatic side, without packing and unpacking for a series of short excursions.

I especially like the small group of roughly 20 people and the amount of food included. You get breakfast, Greek tapas, fruit, salads, snacks, a BBQ lunch, dessert, and drinks throughout the day. The crew also takes GoPro and underwater photos, a useful touch when your hands are busy swimming.

The main caution is the weather. Wind can force the captain to change the route, shorten certain stops, or skip the southern coast. That flexibility is important for safety, but you should book this as a day on the sea rather than a promise to visit every named stop.

Key details before you book

• A full-day sea outing: Plan on about nine hours, from a 9:00 am departure in Adamantas to your return at the same meeting point.
• A Lagoon 440 catamaran: The 44-foot boat gives you room to sit in the sun or get out of the wind.
• Small-group comfort: Capacity is listed at a maximum of 22, with the experience generally capped around 20 people.
• Four main swim stops: You should expect time at Poliegos, Gerakas, Kleftiko, and Kalogries, subject to sea conditions.
• Food and drinks are part of the deal: Greek tapas, fresh salads, fruit, snacks, BBQ lunch, beer, local white wine, ouzo, soft drinks, and water are included.
• Photos are sent afterward: The crew uses GoPro and underwater photography, then sends a set of images by email.

Why a catamaran is the right way to see Milos

Milos is famous for beaches that are awkward or impossible to reach by road. Some require ladders, ropes, or a long walk. Others are best seen from the water because their real character comes from cliffs, caves, colored rock, and clear sea.

A catamaran makes the day less cramped than a small motorboat. The Lagoon 440 has two hulls and a broad deck, so you can sit outside, find shade, or move indoors when the wind picks up. That matters on a nine-hour trip. You are not confined to one bench, and the motion can feel more manageable than on a narrow boat, though anyone prone to seasickness should still prepare.

The group size is another plus. Around 20 people is not private, but it is small enough for the crew to serve food, help with swimming equipment, and keep an eye on conditions. The atmosphere is relaxed rather than a loud party boat. Music plays, but the day is built around swimming, eating, conversation, and scenery.

Captains and crew vary by departure. Names appearing with this service include Yannis, Sivan, Rafail, Flo, Elena, Dina, Andreas, Panos, and Forest. The strongest part of the experience is the care shown on board. On windy days, the captain has changed course for safer bays, while the crew has continued to provide meals, drinks, and help with seasickness.

Setting out from Adamantas at 9:00 am

You meet at the PCFW+PJ Adamantas location in Adamantas. Hotel transfers are not included, so you need to arrange your own way to the port. Allow time to find parking, since the boat cannot be reached by parking directly in front of it and several operators may leave at similar times.

The boat returns to the same meeting point after the day. Bring a swimsuit, towel, sunscreen, and a light hoodie or extra layer. The ride home can feel cool after hours in wet swimwear, even on a sunny day.

Towels and swimsuits are not supplied. Snorkelling equipment, lifejackets, swimming aids, and paddleboards are included. Wi-Fi is also available, which is handy if you want to stay connected, though the best use of your time is probably to put the phone away and watch the coast.

Poliegos and the Galazia Nera Blue Lagoon

The first major swim stop is Galazia Nera on Poliegos, Greece’s largest uninhabited island. This is often the morning highlight: clear water, a bright blue-green color, and a quiet setting that feels far removed from Milos’ port towns.

You get about 40 minutes here, with a late breakfast served around the stop. The water is the main attraction, so bring your mask and take time to look below the surface. The trip supplies snorkelling gear, but you may prefer to bring your own mask if you want a particular fit.

Poliegos is also a good example of why the boat matters. You are not simply being driven to a beach parking area. You are reaching an empty island by sea and seeing a section of the Cyclades that most land-based sightseeing misses.

The stop is not long enough for a full island visit, but that is not the point. This is a swim and breakfast break, with the boat providing shade, food, and a place to dry off before the next stretch.

Seagull Islands and the old sulfur mines

Along the coast, the crew points out the Seagull Islands, an unusual geological formation made of six-sided tubes. The formations were created under great pressure and are rare around the world.

This is a passing sight rather than a long stop, so keep your camera ready. The guide adds context as you cruise by, which makes the coastal scenery more interesting than a simple sequence of swim breaks.

The old sulfur mines appear farther along the southeastern side of Milos. They were used until 1956 and are now abandoned. From the water, you can see a remote industrial site that would be difficult to reach in the same way by road.

These short viewing points give the day some variety. You are not spending all nine hours in the water. You also get glimpses of Milos’ mining past and unusual geology, two parts of the island that can be easy to miss if you only visit beaches.

Gerakas Beach and its pale perlite slopes

Gerakas is one of Milos’ most striking boat-access beaches. Clear emerald water meets large perlite slopes, creating a stark scene of pale sand and bright sea.

The boat stays for about 30 minutes. That gives you time to swim, take photos, and enjoy the setting, but not enough time for a long beach walk. Since access is by boat, you avoid the effort involved in reaching some of Milos’ less accessible coves.

The contrast here is different from Poliegos. Galazia Nera is about the color and clarity of the water. Gerakas adds the mineral character of Milos, where volcanic rock and mining have shaped much of the coast.

Tsigrado, the biggest cave, and the coast by boat

Tsigrado is seen from the water as you pass. The beach can be reached from land using ladders and ropes, but the boat provides an easier way to photograph it without attempting that descent.

You also pass the biggest cave in Milos. These short viewing moments are useful for photography, particularly if you are interested in coastal formations rather than only swimming. The crew uses the route to explain what you are seeing, so keep listening even when the boat is moving between stops.

The sea route also changes your sense of distance. Beaches that look close together on a map can be separated by rough access roads or steep terrain. From the catamaran, you see how the coves connect and how quickly the coast changes from pale sand to dark mine rock and white cliffs.

Kleftiko: the day’s main attraction

Kleftiko is the most important stop on this cruise. Its name refers to a place used by pirates as a hideout, and its setting explains why the site has such a strong reputation: white and gray rock towers, sea caves, and passages cut through the cliffs.

The boat stays a little over an hour. That is enough time for a proper swim, snorkelling, and a turn on the stand-up paddleboard. The crew provides masks and basic guidance on how to explore the water safely around the rocks.

The underwater sections are the special part. You may swim near caves and passages where the water clarity lets you see the rock below. The captain and crew determine where it is safe to enter based on wind, current, and boat position, so do not expect to swim into every opening you can see.

Kleftiko is also where the BBQ lunch is served. That works well, since you can swim first and then eat while drying off. Lunch includes vegan options, alcoholic and nonalcoholic drinks, and additional snacks.

The crew uses GoPro cameras during the stop, including underwater shots, and later sends a set of photos by email. This is particularly useful at Kleftiko, where it is hard to photograph yourself swimming through clear water while also keeping your phone dry.

Kalogries Beach and a quieter swim break

Kalogries is an inaccessible bay on the western side of Milos, with two small beaches and clear turquoise water. The boat stays about 30 minutes, giving you another chance to swim and snorkel after lunch.

This stop is shorter than Kleftiko and Poliegos, but that rhythm works well across a long day. You get a major site, a meal, and then another short water break rather than being expected to spend hours at one beach.

The crew also serves snacks and drinks here. If you prefer a quiet swim rather than a busy beach visit, this can be one of the more pleasant parts of the day, especially when the boat is able to find calm water.

Cape Vani and Milos’ mining past

Near the end of the route, the boat passes Cape Vani, an abandoned manganese and iron mine from the 19th century. The mine opens at the edge of the cape above the sea, with vertical rock and horizontal layers in black and ruby red.

Cape Vani gives the cruise a useful final note. Milos is not only about white beaches and blue water. Its mineral wealth shaped the island, and the colored rock makes that past visible from the deck.

The crew explains the story as you photograph the cape. It is another passing stop, so this is not a walking tour of the mine. Think of it as a coastal view with historical context.

Food, drinks, and the real value of the $241.86 price

At $241.86 per person, this is not a cheap boat ride. The value depends on how much of the package you would otherwise have to arrange separately.

The price covers approximately nine hours on the water, several inaccessible beaches, snorkelling equipment, a paddleboard, Wi-Fi, breakfast, Greek tapas, fruit, salads, a full BBQ lunch, snacks, bottled water, soft drinks, beer, local white wine, and ouzo. It also includes the underwater and GoPro photo service.

The food receives especially strong praise. You should expect more than a single lunch box. The crew serves food at several points during the day, with fresh Greek dishes, salads, fruit, and dessert alongside the BBQ. One useful detail is that the boat is not designed as a drink-heavy party cruise. Music is present but kept at a reasonable level, so the mood remains easygoing.

I see the price as fair for a full day if you value access, meals, and a small group. It is less appealing if you only want a quick swim or plan to spend most of your time on land. The cruise works best when you treat it as one of your main Milos activities, not a short add-on.

Who will enjoy this cruise most

This trip suits you if you want to combine sightseeing and swimming without arranging several separate outings. It is a good choice for couples, families with older children, solo visitors, and anyone who enjoys meeting people in a relaxed setting.

Families with children aged 11 and 14 have enjoyed the swimming, paddleboarding, food, and open space on the boat. Most people can participate, but you need to be comfortable boarding a catamaran, spending much of the day at sea, and swimming from the boat.

It is also a strong pick for photographers and social media users. The coast provides plenty of striking views, the crew takes photos, and Wi-Fi is available. Just remember that weather can change the route and that the best photos may come from being present rather than constantly managing your phone.

You should think twice if you dislike boat motion, need a fixed schedule, or want long walks at each beach. The stops are built around swimming and viewing, not extended time ashore.

Weather, route changes, and comfort

The captain has the final say on the route. If the southern coast is too windy, the boat may visit safer beaches or alter the order of the stops. This can mean missing a named site, but it is the right tradeoff for comfort and safety.

Wind can also make the ride home chilly. Bring a hoodie or spare layer, apply sunscreen before boarding, and reapply during the day. Avoid spray sunscreen, since it can spread across the boat’s surfaces.

The crew has also offered seasickness chewing gum and practical help on rough days. That does not guarantee calm seas, so pack whatever medication you normally use and sit where you feel most comfortable if the water becomes unsettled.

Free cancellation is available up to 24 hours before departure. If poor weather cancels the trip, you can choose a different date or receive a full refund. The same applies if the minimum number of people is not reached.

Should you book it?

I would book this cruise if you have one full day in Milos and want to see the beaches that are hardest to reach by land. Kleftiko, Poliegos, and Gerakas give you a strong mix of caves, clear water, mineral rock, and open sea, while the food and drinks make the long day easy to enjoy.

The best reason to choose POLCO SAILING is the complete package: a spacious catamaran, a small group, generous meals, friendly crew, swimming gear, paddleboarding, and photos afterward. The main limitation is the price and the fact that wind can change the route.

Book it for the chance to experience Milos from the water, not for a guaranteed checklist of every beach. If that sounds right, this is one of the most useful full-day choices on the island.
