Round of Milos and Poliegos Sailing boat snorkelling cruise

Milos looks best from the water. This full-day sailing trip links the island’s famous coves, sea caves, old mines, and Poliegos’ glowing blue waters in one long outing. I like the small-boat format and the several chances to swim, while the included lunch, drinks, snorkeling equipment, and underwater GoPro photos add real value. The main caution is simple: nine hours is a long time on a boat, and seating may feel tight if the boat reaches its stated capacity.

I also like the crew’s effort to explain places such as Cape Vani, Klima, and the sulfur mines instead of treating the cruise as a string of photo stops. Guides including Andreas, Spiros, Yannis, Panos, Dina, and Captain Nick have been praised for being friendly and attentive. Still, the boat may skip some areas when wind makes the route unsafe, and snorkeling gear or paddleboards may not always be available in practice.

Key points before you book

• Kleftiko is the star stop: White rock, caves, clear water, and former pirate hideouts make this the trip’s main swimming and snorkeling stop.
• You get several chances to swim: Kalogries, Kleftiko, Gerakas, and Poliegos each offer time in the water, though the exact route can change with wind.
• The price covers a full boat day: At $193.57 per person, lunch, drinks, snacks, equipment, Wi-Fi, and GoPro photos are included.
• Small-group comfort has limits: The tour is described as capped at 16 people, while the practical information lists a maximum of 12. Confirm the boat size and passenger count.
• Bring your own towel: Towels are not included, and you will spend much of the day moving between swimming stops.
• Plan for a long outing: Departure is at 9:00 a.m. from Adamantas, with the boat returning to the same meeting point after roughly nine hours.

Setting out from Adamantas at 9:00 a.m.

The cruise begins at PCFW+PJ Adamantas, in Adamantas on Milos. There is no hotel pickup or drop-off, so you need to make your own way to the harbor meeting point. The activity ends back where it begins, which keeps the transport side easy once you reach the marina.

This is not a quick harbor trip. You are signing up for about nine hours at sea, with several stops, a meal, drinks, and time spent simply sailing between places. That length is useful because Milos and Poliegos have many coves that are difficult or impossible to reach by road, but it also means you should be comfortable sitting outdoors for much of the day.

The boat is intended to offer a more personal outing than a large excursion vessel. The supplied details describe an all-inclusive cruise capped at 16 people, while the additional information lists a maximum of 12. That difference matters. If you care about elbow room, ask POLCO SAILING which boat is being used and how many people are booked for your date.

The crew usually plays an important part in the day. Their role is not only to handle the boat, but also to explain the places along the coast and help people feel at ease before getting into the water. Several crew members, including Andreas, Spiros, Yannis, Panos, Dina, and Captain Nick, have been singled out for their warmth, humor, and attention to the group.

Cape Vani and the red-and-black mine

Cape Vani gives you an early look at Milos’ industrial past. The abandoned manganese and iron mine dates from the 19th century, and its large opening reaches the sea at the edge of the cape. Vertically cut rock surrounds the mine, with horizontal layers in dark black and ruby-red tones.

You view the site from the boat and have time for photographs while the crew explains its background. This is not an inland mine tour, so you should not expect to walk into the excavation. Its value is in the contrast between raw rock, old industry, and the open sea.

The stop also helps break up the day before the main swim locations. If you enjoy geology, old working sites, or unusual coastal views, you will appreciate this pause. If your only goal is swimming, it may feel less important than the coves later in the route.

Kalogries offers a quiet first swim

Kalogries is a remote bay on Milos’ western side, reached by boat rather than an ordinary road visit. Clear turquoise water surrounds two small beaches on the north and east sides of the bay. The boat stays for about 30 minutes.

That half-hour is enough for a quick swim, a little snorkeling, and snacks or drinks. It is also a useful first chance to test the water and get comfortable with the boat’s swimming setup. The stop is short, so do not expect a long beach visit or time to wander inland.

The appeal here is the setting. Kalogries is quieter and less developed than the island’s easy-to-reach beaches, and seeing it from the water gives you a sense of why a sailing trip is useful on Milos. You can jump from the boat, swim toward the shore, or stay aboard and enjoy the view.

Kleftiko earns its headline position

Kleftiko is the cruise’s main attraction. The name refers to a place used by pirates as a shelter, and its white and gray rock formations create a striking series of caves, openings, and sea passages.

The boat stays here for about an hour. Masks and fins are provided, and the crew offers suggestions for exploring the water around the rocks. The clarity is a major part of the appeal. You may swim near cave entrances and through underwater openings, though you should follow the crew’s directions and judge your own comfort carefully.

The boat does not necessarily take you into every cave. One account makes clear that the crew docks the boat while people choose how far they wish to explore, so this is not a guided cave walk. That means you have freedom, but you also carry responsibility for staying within your ability and returning to the boat on time.

The crew uses a GoPro to take photographs, including underwater shots. The set is sent to you by email later. This is a useful extra because it lets you enjoy the water without trying to manage a phone or camera at the same time. Ask how the images will be delivered before you leave, and make sure the crew has your correct email address.

Kleftiko is also where the quality of the snorkeling equipment matters most. Most of the supplied information presents the masks and fins as included, but one less favorable experience found the equipment incomplete and not especially clean. If you have your own mask, bringing it is sensible. If you do not, inspect the provided gear before leaving the boat.

Gerakas combines pale sand and lunch

Gerakas is another beach that is accessible only by boat. Huge slides of perlite sand form the coast, ending at a clean beach and clear emerald water. The pale sand and unusual rock make this one of the more distinctive stops on the southern side of Milos.

The supplied schedule lists about 40 minutes here, while the description of the stop says the group will spend about one and a half hours swimming and eating lunch. That is a meaningful difference, so confirm the expected timing when you book. It may reflect a route change or a description that has not been fully updated.

Lunch is homemade and includes vegetarian and vegan choices. Food is served onboard, and drinks include bottled water, soda, beer, wine, and local Greek spirits. Several people have praised the quantity and taste of the meal, with special approval for food prepared by Dina. One less favorable account found the food disappointing, so it is best to see lunch as a convenient included meal rather than a restaurant experience.

Gerakas is a good place to slow the day down. If the stop lasts close to the longer time described, you can swim, eat, and sit on deck without rushing. If the stay is closer to the shorter listed time, expect a quick meal and swim rather than a long beach break.

The sulfur mines show another side of Milos

The old sulfur mines sit on the southeastern part of the island and date back to 1856. They closed in 1956 and were left behind. Like Cape Vani, this is a place best viewed from the boat, not a walking visit.

The mines add historical interest to a day otherwise centered on swimming. You see a remote section of Milos that many beach-focused outings skip, while the crew explains how mining shaped the island. If the sea is rough or the route changes, the exact viewing time may vary.

This is one reason the cruise works better for people who want a broad look at Milos than for people seeking nonstop time in the water. The boat alternates between natural scenery, swimming, and short explanations of the island’s past.

Poliegos and the blue waters of Galazia Nera

Poliegos is Greece’s largest uninhabited island. The main stop is Galazia Nera, an area known for unusually clear water and a bright, almost fluorescent blue color.

The planned stay is about 30 minutes. You can swim, snorkel, try the paddleboard, or remain on the boat with snacks and drinks. The stop is short, but its water quality makes it one of the most memorable parts of the route.

Paddleboarding is advertised as an option, yet one positive account specifically noted that no paddleboard or snorkeling equipment was available that day. Conditions, equipment, or the particular boat may explain the difference. If using a paddleboard is important to you, confirm it before departure rather than treating it as guaranteed.

Poliegos is also a good reminder that weather controls the experience. One outing changed its route because of wind and spent more time on the northern side instead of going south. The crew’s first duty is safe sailing, so the printed route should be viewed as a plan rather than an absolute promise.

Klima and the strange Seagull Islands

As the boat continues, you pass Klima, the former capital of Milos and the place where the Venus de Milo was found. The colorful fishing village makes a natural photo stop, and the crew shares historical details while you look from the water.

This is a view-only part of the trip. You should not expect time to walk through Klima or visit the discovery site. Still, seeing the village from offshore gives you a useful connection between the island’s ancient fame and its working coastal communities.

The Seagull Islands add a geological footnote. Their name refers to the many seabirds associated with them, while the formations themselves were made by lava that cooled into hexagonal tubes. Similar formations occur in only a small number of countries, making this a worthwhile sight even though the stop may be brief.

What is included, and what is not

The $193.57 price needs to be judged against the entire day, not just the boat ride. You receive:

• Homemade lunch, including vegetarian and vegan choices
• Bottled water, soft drinks, beer, wine, and local Greek spirits
• Fruit and snacks
• Snorkeling equipment
• GoPro photographs, including some taken underwater
• Wi-Fi onboard
• Crew commentary about the places visited

You still need to bring a towel. Hotel transport is not included, and the minimum drinking age for alcohol on the tour is 18.

At this price, the cruise is not the cheapest way to spend a day in Milos. It can be good value if you would otherwise pay separately for transport, meals, drinks, snorkeling gear, and access to boat-only beaches. The value weakens if you dislike long boat days, prefer a large amount of time on shore, or expect a polished food-and-equipment service.

Comfort, timing, and practical limits

The greatest issue is space. One account found the smaller boat uncomfortable with a full load, while another said the crew worked hard to keep everyone comfortable. The service appears to depend partly on which of the company’s two boats is operating and how many people are aboard.

The day is also exposed to weather. Wind can change the route or remove southern stops. That is not a flaw unique to this company, but it is important when you have a fixed mental picture of the itinerary.

Bring a towel, hat, sunscreen, and any personal snorkeling gear you prefer. The boat provides drinks and food, but personal comfort items remain your responsibility. Internet is available onboard, though one account found the connection spotty. Treat Wi-Fi as a bonus, not as a reason to choose this cruise.

People with mobility limitations should note that the experience is not recommended for them. Most people can participate, and service animals are allowed. A multilingual guide may operate the trip.

Who should book the Milos and Poliegos cruise?

I would choose this outing if you want to see several remote coastal places in one day and you enjoy swimming from a boat. It suits couples, friends, and solo visitors who value a social but fairly small group, strong scenery, and an included meal.

It is also a good pick if Kleftiko is high on your Milos list. The combination of caves, clear water, GoPro photographs, and crew guidance gives the stop more substance than a simple coastal pass.

I would think twice if you need lots of room, dislike sitting for long periods, or want guaranteed access to every listed activity. The day can feel long, and the equipment, seating, route, and stop lengths may vary.

The tour offers free cancellation up to 24 hours before departure. Cancellations inside that window are not refunded, and missed departures caused by a late or absent cruise-ship arrival are not covered. Poor weather or failure to reach the required minimum may lead to another date or a full refund.

Should you book it?

Book it if your ideal Milos day means turquoise water, remote beaches, old mines, sea caves, and several chances to swim without arranging separate transport. The crew’s friendly service, homemade food, and included GoPro photos make the $193.57 price easier to justify.

Skip it in favor of a shorter trip if nine hours sounds tiring or if comfort matters more than covering a lot of coastline. Before paying, confirm the passenger limit, boat size, Gerakas timing, and availability of paddleboards. Those details will tell you whether this is a relaxed small-group cruise or a crowded full-day outing.
