Long left untouched and uninhabited, Poliegos now draws visitors from across the Cyclades who come for its electric blue waters and rare, crowd-free silence
Poliegos is the largest uninhabited island in the Aegean Sea and a protected Natura 2000 sanctuary east of Milos, in the Cyclades, best explored on a boat tour. Formed by the same volcanic arc as Milos and Kimolos, it is a compound volcano with mineral-rich cliffs colored by iron, sulfur, and manganese, known for its glowing turquoise water and rare, crowd-free calm.
In earlier times, mariners used Poliegos as a quiet point between trade routes, sheltering near its gentle cliffs and calm bays during coastal passages between Milos, Kimolos, and nearby islands. Travelers paused here to rest, gather fresh water, or wait for safer conditions before continuing across the Aegean.
Today, the island draws visitors for its clarity and striking volcanic geology. Swim stops at Blue Bay and Mersini open onto bright shallows framed by red, white, and yellow cliffs. Navy Blue features Poliegos as a highlight on Private and Semi-Private Cruises from Milos.

Everything you need to know about our boat tours to Poliegos in Milos
Poliegos is the largest uninhabited island in the Aegean Sea and one of the most requested stops on Navy Blue cruises from Milos. Formed by the same volcanic arc as Milos and Kimolos, the island is a compound volcano with mineral-rich cliffs shaped by iron, sulfur, and manganese. Its turquoise water, colorful rock faces, and complete absence of development create a setting unlike anything else in the Cyclades. The island is a protected Natura 2000 site, meaning its coastline and marine environment remain untouched.
Swim stops at Blue Bay and Mersini reveal water so clear that the seabed is visible from the deck. The island’s sheltered coves offer calm conditions ideal for snorkeling and paddleboarding. Because Poliegos has no port, no roads, and no permanent residents, the only way to visit is by boat. Navy Blue’s Private and Semi-Private Cruises include Poliegos as a highlight on North and Round Cruise itineraries from Milos.
Poliegos offers swimming in turquoise coves, snorkeling over rock formations, and paddle-boarding in sheltered bays. The main stops include Blue Bay, known for its vivid color and shallow entry, and Mersini, a quieter cove surrounded by pale cliffs. The coastline features sea caves, natural rock arches, and underwater formations visible in the clear water.
There are no facilities, beaches, or paths on the island, so the entire experience takes place from the yacht and the water. Your crew anchors in the calmest spots and provides all equipment on board. Between swim stops, Mediterranean meals and open bar are served on deck with views of the shoreline. The isolation and natural beauty of Poliegos make it a standout stop on any Milos boat tour.
The best time to visit Poliegos is from late May to early October when the Aegean Sea is warm and calm. June and September offer ideal conditions with fewer boats and comfortable water temperatures around 22 to 25 degrees Celsius. July and August are the warmest months but can bring stronger north winds in the afternoon.
Navy Blue’s captains select the best route based on daily sea conditions, and Poliegos is most commonly included on North Cruise and Round Cruise itineraries when winds are favorable. Morning departures typically offer the calmest water at the island. For travelers seeking a quieter experience with fewer boats at anchor, early and late season visits are recommended.
Yes, Poliegos is safe for swimming and well suited for families with children. The main coves, including Blue Bay, feature shallow entries with calm, clear water and no strong currents. The crew anchors in sheltered positions and supervises water access from the swim platform, making entry and exit easy for younger swimmers.
Snorkeling gear in multiple sizes is provided on board, and children can explore the shallow seabed near the yacht under crew supervision. The smooth rock below the surface is easy to see in the clear water, adding to the safety for inexperienced swimmers. Shaded deck areas, freshwater shower, and meals served on board mean families can spend the full stop comfortably without needing to go ashore. A Private Cruise offers the most flexibility for families, with the pace and duration of each stop adjusted to suit your group.
Poliegos is the largest uninhabited island in the Cyclades, a compound volcano, and one of very few Natura 2000 protected islands in Greece. Unlike popular destinations such as Santorini, Mykonos, or Paros, Poliegos has no roads, no buildings, no port, and no permanent residents. The island’s volcanic geology has created dramatic cliff faces colored by iron, sulfur, and manganese deposits, giving its coastline vibrant red, white, and yellow tones found nowhere else in the Aegean.
The water surrounding Poliegos is among the clearest in the Aegean, with visibility reaching several meters below the surface. Its coves are accessible only by boat, which limits visitor numbers and preserves the quiet, untouched character of the island. Navy Blue’s cruises from Milos bring you directly to the best swim spots, where the combination of turquoise water, mineral-rich rock, and complete silence creates an experience that stands apart from any other island visit in the Greek Islands.

Poliegos felt like discovering a secret. No buildings, no other people, just bright blue water and white rock everywhere. The crew found us a cove where we were completely alone. This is how the Greek Islands should be experienced.
