Best of Milos and Poliegos Catamaran snorkelling Cruise with BBQ

The best part of this Milos cruise is simple: it takes you to coves and beaches you cannot easily reach by land. A full day aboard the 44-foot Lagoon 440 brings you to Poliegos’ brilliant Blue Lagoon, Gerakas, Kleftiko, and Kalogries, with time to swim rather than just point a camera from offshore.

I like the small-group setup, with the boat generally limited to about 20 people and a formal maximum of 22. I also like the generous food plan: Greek tapas, fruit, salads, a BBQ lunch, local wine, beer, ouzo, and nonalcoholic drinks are part of the price. The main consideration is the sea. Wind can force the captain to change the route, and nine hours on a boat may feel long if you want a quick outing.

Key points to know before booking

• Poliegos’ Blue Lagoon: Spend about 40 minutes swimming in the clear, fluorescent water of Greece’s largest uninhabited island.
• Kleftiko by boat: Explore sea caves, white rock formations, and underwater passages with masks, paddleboards, and GoPro photography.
• Food throughout the day: Fresh Greek tapas, snacks, fruit, salads, and a BBQ lunch are included, along with beer, wine, ouzo, soda, and water.
• A relaxed boat, not a party vessel: Music is played, but the atmosphere is generally calm rather than loud or rowdy.
• Weather controls the route: The captain may replace southern stops with safer bays when wind and waves rise.
• Practical limit: Bring a towel, swimsuit, sunscreen, and something warm for the return trip. Hotel transfers are not included.

Why this is one of Milos’ best full-day outings

Milos is famous for beaches with strange colors and shapes, but several of its finest places are difficult or impossible to reach by road. A boat solves that problem in one sweep. You see the island’s southern cliffs, old mines, sea caves, and small bays while moving between swim stops.

This is not a quick sightseeing cruise. The trip lasts about nine hours and begins at 9:00 a.m. from the Adamantas meeting point at PCFW+PJ Adamantas. You return to the same place at the end of the day.

The catamaran matters. A Lagoon 440 gives you more room than a small speedboat, with space to sit in the sun or get out of the wind. The group size also helps. The boat is described as limited to around 20 people, with a stated maximum of 22, so you should not expect a packed excursion vessel.

The crew is a major part of the experience. Depending on the sailing date, you may meet people such as Captain Yannis, Flo, Elena, Dina, Andreas, Rafail, Viviana, Louisa, or Panos. The crew handles the meals, explains the sights, helps with swimming equipment, and adjusts the route when conditions require it.

Adamantas to the old capital at Klima

The day includes views of Klima, the former capital of Milos and the place where the Venus de Milo statue was found. Its colorful fishing houses make it an easy photo stop, especially in the softer light later in the day.

You may not spend a long time ashore here. This is mainly a guided view from the water, with the crew providing background as the boat passes. That makes it useful for orientation, but it is not a replacement for visiting Klima on foot if you want to explore the village closely.

The cruise also passes the Seagull Islands, a rare geological formation made of six-sided stone columns. Their shape comes from immense pressure over time, creating a striking pattern from the water.

Other passing sights include the old sulfur mines in southeastern Milos. The mines were used until 1956 and are now abandoned. From the boat, you can see a remote industrial site that would be difficult to appreciate from the main roads. The crew also points out the largest cave on Milos and Cape Vani, where an old manganese and iron mine cuts into the shoreline in black and ruby-red layers.

These passages give the cruise more substance than a series of pretty swim stops. You get a look at the island’s geology and mining past without losing much time in the water.

Poliegos and the 40-minute Blue Lagoon stop

The first main swim stop is Galazia Nera, also called the Blue Lagoon, on Poliegos. Poliegos is the largest uninhabited island in Greece, and its lack of development is part of the appeal.

The water here is exceptionally clear, with a strong blue-green glow. You get roughly 40 minutes to swim before a late breakfast is served. Snorkeling is included, although this is primarily a water-and-color stop rather than a place known for a long reef exploration.

The timing works well. You are still early in the day, so the first swim gives you a chance to cool off and settle into the rhythm of the boat. The breakfast spread is made up of fresh Greek-style food, with snacks and drinks continuing during the cruise.

The tradeoff is that 40 minutes passes quickly. If you prefer to linger in one bay, a full-day route with several stops may feel busy. If you want to see a range of Milos and Poliegos in one day, the schedule is a good fit.

Gerakas, Tsigrado, and the beaches without roads

Gerakas is one of the most distinctive stops on the south side of Milos. Emerald water meets huge perlite sand slides, creating a stark setting that looks very different from a conventional sandy beach.

You spend about 30 minutes here. That is enough time to swim, take photographs, and get a sense of the place, but not enough for a long shore visit. Gerakas is accessible only by boat, which gives this stop real value. You are not simply avoiding a crowded road. You are reaching a bay that has no normal land access.

The boat passes Tsigrado for photographs. The beach can be reached by sea or by using ladders and ropes from land, so seeing it from a catamaran is the easier option. This is a photo pass rather than a swim stop, and that distinction is worth noting if Tsigrado is high on your personal list.

The southern coast is one of the reasons to choose a boat day instead of trying to assemble separate beach visits. You see places that would take considerable effort to reach independently, and you do not need to worry about parking, rough access paths, or carrying beach gear over land.

Kleftiko: the main event

Kleftiko is the centerpiece of the cruise. Its name refers to a place of thieves, since pirates once used the area as a shelter. The real attraction today is the unusual formation of pale and gray rocks, sea caves, and clear water.

The boat stays for a little more than an hour. You can swim through the area, look into underwater passages, and use the supplied masks and snorkels. Stand-up paddleboards are also available.

This is the stop where the catamaran format pays off most. A smaller vessel might get you close, but the extra room makes it easier to change, eat, dry off, and take a break between swims. You are also less likely to feel that the whole day depends on rushing in and out of one narrow cove.

Lunch is served here, with a BBQ and vegan options. Food is prepared on board and accompanied by drinks, salads, and other Greek dishes. Several meals and snack services are spread across the day, so you are not left relying on a single sandwich at midday.

The crew also uses GoPro and underwater cameras at Kleftiko. A set of photographs is sent to you by email later. This is a useful extra, especially if you want pictures of yourself in the water rather than only photographs of the rocks. The boat also has Wi-Fi, which suits anyone who wants to share the day while still at sea.

Keep your expectations sensible. Underwater photos depend on water clarity, light, movement, and how many people are swimming at once. Treat the pictures as a welcome extra, not the sole reason to book.

Kalogries and the return along Milos

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

This is a pleasant contrast to Kleftiko. Kleftiko is about rock formations and caves, while Kalogries is more about a quiet bay and clear water. Since the cruise includes several swim stops, you can choose your pace. You might swim at every stop, or sit back and save your energy for the places that interest you most.

The route then continues past more coastal features before returning to Adamantas. On the way, you have time to photograph Cape Vani and its old mine. The captain or crew explains the site as you pass its sharply cut rock face and colored mineral layers.

A return sail can be cooler and windier than expected, even after a warm day. Bring a light hoodie or another layer. This small bit of planning can make the final part of the trip much more comfortable.

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

At $241.86 per person, this is not the cheapest way to spend a day on Milos. The price makes more sense when you add up what is included: about nine hours on a catamaran, several remote swim stops, snorkeling equipment, paddleboards, breakfast-style food, snacks, a BBQ lunch, fruit, salads, bottled water, soda, beer, local white wine, and ouzo.

You are also paying for a crew of three on many departures, route planning, onboard service, and the boat itself. Hotel pickup is not included, so you need to get yourself to the Adamantas meeting point. Towels and swimsuits are also your responsibility.

The food receives especially strong praise. Expect more than a basic grill plate. The day can include homemade Greek tapas, fresh salads, fruit, and multiple serving times. If you have dietary needs, vegan options are specifically provided, but you should still share any important requirements when booking.

The drinks help the value, but the atmosphere is not designed as a drinking party. Music plays, though the mood is generally relaxed. That makes the cruise a better choice for couples, families, and people who want conversation and swimming rather than loud entertainment.

The weather question you should take seriously

Milos is exposed to wind, and the captain has the final say on the route. The southern side of the island may not be safe or comfortable on a rough day. In that case, the boat can reroute to more sheltered beaches and sites.

This is not a weakness in the operation. It is part of taking a boat around an island with open water and changing conditions. Captains such as Yannis have adjusted routes, slowed down, and chosen safer bays when seas became rough.

Still, you should book with flexibility. You may not see every named stop. One departure may reach the Blue Lagoon and Kleftiko, while another spends more time on the protected side of Milos. The stated policy offers a different date or a full refund if poor weather cancels the cruise.

If you are prone to seasickness, take the possibility seriously. Crew members have offered chewing gum and practical help on rough days, but prevention is still wise. Eat lightly before departure, use any medication you normally rely on, and stay in a part of the boat that feels comfortable for you.

Who will enjoy this cruise most

I would choose this cruise if I wanted one major water day rather than several short beach trips. It suits you if you want:

• Access to beaches and bays that cannot be reached easily by land
• Plenty of time in the water
• A comfortable catamaran instead of a small open boat
• Greek food and drinks included in the fare
• A social but generally relaxed atmosphere
• Photos and video from the crew
• A family outing with swimming and paddleboarding
• A strong mix of scenery, history, geology, and beach time

Families with children around 11 and 14 have enjoyed the swimming, paddleboarding, food, and open space. It can also work well for solo visitors, since the communal setup makes it easy to meet people without requiring a party mood.

I would hesitate if you dislike long boat days, want complete control over your schedule, or need every stop to happen exactly as advertised. You should also think twice if you want a quiet private charter. This is a small-group cruise, not a boat reserved just for you.

What to bring for a more comfortable day

Wear your swimsuit from the start. There is no need to lose time changing before the first swim. Bring a towel, since one is not provided, and pack a light layer for the trip back.

Apply sunscreen before boarding and reapply during the day. Avoid carrying loose spray sunscreen, since overspray can make a mess on the boat. Sunglasses, a hat, and a waterproof way to protect your phone are sensible additions, though the supplied GoPro service gives you another way to keep memories of the swim stops.

Arrive with enough time to find parking near the port. You cannot park directly in front of the boats, and several operators may leave around the same time. Hotel transfers are not included, so plan your route to Adamantas in advance.

Should you book the Milos and Poliegos catamaran cruise?

Book it if you want the broadest possible view of Milos from the water, with food, drinks, swimming equipment, and a capable crew folded into one long day. The Blue Lagoon and Kleftiko are the strongest reasons to go, while Gerakas and Kalogries add variety.

The price is high, but the inclusions are unusually generous for a nine-hour outing. I would especially recommend it early in your stay, since it gives you a clear sense of the island’s coast and reaches beaches you may not otherwise see.

Skip it if you want a short, low-cost boat ride or if changing weather would frustrate you. For most people who enjoy swimming and can accept a flexible route, this is one of the most efficient and memorable ways to experience Milos.
