White cliffs, no buildings, no residents and no facilities — the largest uninhabited island in the Aegean, sitting east of Milos. It is a full day or it is nothing, because Polyaigos is a separate island.
The Experience
From the operator's own listing — the catamaran, the crossing and both destinations.
Good to know: The itinerary may vary depending on weather conditions and the skipper’s discretion. · In case of winds stronger than 5 Beaufort, the tour will conclude in Pollonia instead of Adamas. A private transfer (at our expense) will be arranged for all guests from Pollonia back to Adamas. · In case of strong northern winds, the cruise may operate on the south side of the island, with boarding at Agia Kyriaki and swimming stops at Gerakas, Kleftiko, Tsigrado, Poliegos, Polonia, or Agia Kyriaki (depending on conditions). · Not suitable for: Pregnant women, Wheelchair users · Not Included: Hotel pickup and drop-off, Tips
An open crossing, an anchorage, a long swim, and nothing ashore.
Two do: Kleftiko and Polyaigos have no road access at all. Sykia cave is reachable only from the sea. Sarakiniko, Firiplaka and Papafragas are free and you can drive to them. Booking a boat to see Sarakiniko is the most common mistake on this island.
The meltemi is a strong northerly that blows through the Aegean summer. It decides whether a Milos boat day is glassy or a washing machine, and operators reroute or cancel on the worst of it. Free cancellation matters more here than on almost any trip we cover.
A half day reaches Kleftiko. Only a full day reaches Kleftiko AND Polyaigos, because Polyaigos is a separate uninhabited island further east. If Polyaigos is on your list, a half-day trip cannot deliver it, whatever the photographs suggest.
Sailboats and catamarans are slower and more comfortable; speedboats reach Kleftiko in a fraction of the time and spend longer there; self-drive rentals need no licence in most cases and put the whole day in your hands. The price runs roughly $58 to $1,744.

The Independent Guide
It is not a stretch of Milos coastline. It is a different island, and the crossing is the product.
Polyaigos is not part of Milos. It is a separate island, east of it, across open water.
That single fact explains everything else about booking it, and it is the thing most people miss because the photographs sit alongside Kleftiko’s in the same search results.
Getting there and back fills most of a day. So:
If the white cliffs in the image you saved are Polyaigos and you have booked a half-day cruise, you will not see them. Read the stop list rather than the thumbnail — the supply bears this out, with 16 products naming Polyaigos against 28 naming Kleftiko, and the overlap almost entirely full-day sailboats and catamarans.
Nothing, and that is the point.
Polyaigos is the largest uninhabited island in the Aegean: white cliffs, protected status, no residents, no buildings, no jetty, no shade and no water. There are goats, which is what the name refers to. The water against pale rock reads as improbably turquoise, and there is nothing man-made anywhere in the frame.
You anchor, you swim, you look. Some trips will put a tender on a beach depending on conditions, but there is nothing to walk to — no path, no facility, nothing.
Bring everything you need and take everything away. The emptiness is the product, and the operators are noticeably careful about keeping it that way.
If you have a spare full day, yes. If your Milos time is short, Kleftiko alone is the better use of it.
The honest distinction: Kleftiko is the more spectacular hour; Polyaigos is the better afternoon. Kleftiko has arches, caves and drama at close range. Polyaigos has scale, silence and colour, and no single feature you would photograph in isolation.
Doing both is what makes the full day feel complete rather than repetitive, which is exactly why the pairing is the island’s signature trip.
If you only have a half day, take it to Kleftiko and do not feel short-changed.
This is the trip where the meltemi matters most.
The run to Polyaigos is open water, so it is considerably more exposed than a coastal hop along Milos’s sheltered southwest side to Kleftiko. On a calm day it is straightforward and beautiful. In a strong northerly it is the leg operators shorten or drop first — and a trip rerouted to Kleftiko alone is still a good day, but it is not the day you booked.
Two practical consequences:
Book with free cancellation, which is standard here, and keep a spare day in the week if you can.
Prefer a catamaran for the crossing if comfort matters. It is the steadiest platform in open water, which is why the featured trip here is one, and why it costs more than the sailboats.
Full-day sailboat, about $145 — 4.9 from 2,017 verified reviews, the deepest sample on the island by a wide margin, lunch included, and it reaches both boat-only destinations. On evidence-to-price it is the strongest booking on Milos.
Full-day catamaran, about $244 — 4.8 from 188 reviews. More comfortable on the open crossing, more space, generally more generous on food.
Shared morning cruise from Pollonia, about $116 — 4.9 from 48 reviews. Pollonia sits on the island’s northeast corner, so this is the shortest crossing to Polyaigos and the cheapest way to reach it. It does not include Kleftiko.
That last option is the one people staying in Pollonia consistently overlook.
A long day on a boat, a lot of swimming, and nothing to do ashore. Children happy in deep water and content on a boat for six hours tend to love it; those who are not will find the crossing long and the stops repetitive, and there is no way to cut the day short once you have set out.
For families, the half-day Kleftiko trips or the Tsigrado kayak tour make a better first outing — and leave a longer trip available later in the week if it goes well.

Guest Reviews
"Maria the captain is the best, we had a great time at the 10 hrs tour. Heaps of space, heaps of food. Stoped at so many amazing places. It was mid-august but felt like we’re the only one in the ocean. Unreal hospitality. Would highly recommend on that tour!"
"This was the highlight of our trip for all 7 of us, ranging in ages from 15-58. The crew was outstanding, the chef was incredible, the catamaran was immaculate and the locations we visited were astounding."
"A fantastic experience: a 10-hour boat ride visiting the most beautiful places that cannot be reached by land, which allowed us to appreciate how wonderful the island is, and they also explained the history of the place to us. And making several stops at the most beautiful spots. Super crew. Despite the small inconvenience of the delayed departure at 11 am, they still allowed us to complete the entire tour, delaying the arrival to 9 pm and letting us see a beautiful sunset from the boat. So, super efficient and organized. And friendly. Highly recommended experience. Beautiful. An absolute must-do."
"Best food we’ve had on the island. Great boat with plenty of room to sit or lounge in sun or shade, snorkels and pool noodles provided. Wonderful swimming spots. It is a full 10 hours so lock in. Must go!"
"Fantastic. Food was excellent, drinks abundant and crew very helpful. Boat was in excellent condition."
"The tour and beaches was amazing but truly the crew and food made on board was top tier!!!! Super friendly and welcoming made the experience feel very worth it"
"A MUST if visiting the island of Milos! The only way to see iconic areas like Kleftiko Bay, Polyaigos island and Gerakas Beach and WOW these swimming spots are just picture perfect with the clearest, bluest turquoise blue water- I found myself speechless most of the time and simply saying "WOW" when I could muster up a word LOL it's an expensive activity but absolutely worth it in my opinion! You'll never forget an experience like this and the lunch served onboard was both plentiful and pretty darn good! Laying out on the top of the catamaran while sailing that beautiful coastline with sun shining and a gentle breeze was an absolute VIBE! 😅🌞🌊"
"It was really fun! The food was delicious. The crew was nice!!"

The largest uninhabited island in the Aegean, and why only a full day reaches it.
The largest uninhabited island in the Aegean, lying east of Milos - white cliffs, no buildings, no residents and no facilities. It is protected, and the complete absence of development is the reason to go: the water reads as improbably turquoise against pale rock, with nothing man-made in the frame. You will also see goats, which is what the name refers to. There is nothing to buy, nowhere to shelter and no path anywhere, so a visit means anchoring, swimming and looking. Sixteen of the 57 Milos boat trips we track name it, almost all of them full days.
Because it is a different island, and the crossing plus the return fills most of a day. This is the single most useful thing to understand before booking on Milos. Half-day trips go to Kleftiko, on Milos's own southwest coast. Polyaigos is east, across open water. Any itinerary promising both in half a day is either counting generously or showing you a photograph taken somewhere else - check the stop list rather than the thumbnail. If Polyaigos is genuinely on your list, book a full day and plan nothing else for it.
If you have a spare full day, yes. If your Milos time is short, Kleftiko alone is the better use of it. Polyaigos is quieter, emptier and arguably more beautiful than Kleftiko, but it is a swimming-and-looking destination rather than a dramatic one - no arches, no caves to enter, just cliffs, water and absence. Kleftiko is the more spectacular hour; Polyaigos is the better afternoon. The full-day pairing is the island's signature trip precisely because the two are different in kind, and doing both is what makes the day feel complete rather than repetitive.
Boats anchor and you swim; there is no port, no jetty and no facilities of any kind. Some trips will put a tender ashore on a beach depending on conditions and the operator's practice, but there is nothing to walk to - no path, no shade, no water. Treat it as a swimming stop in extraordinary surroundings rather than an island you visit. Bring everything you need with you, and take everything away: the island's protected status and its emptiness are the whole product, and the operators are noticeably careful about it.
The full-day sailboat at about $145 has by far the deepest evidence - 4.9 from 2,017 verified reviews - and reaches Kleftiko as well. For a catamaran instead of a sailboat, the full-day to Poliegos and Kleftiko at about $244 rates 4.8 from 188 reviews and is the more comfortable platform on a long day. Smaller and cheaper options exist from Pollonia at about $116, which is the shortest crossing since Pollonia sits on the island's northeast corner. Prices span $116 to over $400 for private charters, and the differences are boat, group size and food rather than destination.
It depends entirely on the meltemi, and this is the trip where that matters most. The run to Polyaigos is open water, so it is more exposed than a coastal hop to Kleftiko. On a calm day it is straightforward and lovely; in a strong northerly it is the leg operators shorten or drop first. This is the specific reason to book Polyaigos trips with free cancellation and to keep a spare day if you can - a rerouted trip to Kleftiko instead is a good day, but it is not the day you booked. The wind guide.
It is a long day on a boat with a lot of swimming and nothing to do ashore. Children who are happy in deep water and comfortable on a boat for six hours or more tend to love it; children who are not will find the crossing long and the stops repetitive. There is no beach infrastructure, no shade beyond the boat's, and no way to cut the day short once you have set off. For families the half-day Kleftiko trips, or the kayak tour on the south coast, are usually the better first outing - and they leave the option of a longer trip later in the week.
