Towering white cliffs and pirate-era sea caves along the southern coast of Milos
Kleftiko is a cluster of white volcanic cliffs and sea caves along the southern coast of Milos, in the Cyclades. Shaped by wind and salt water into stone arches and turquoise coves, it is unreachable by road and accessible only by sea, best explored on a boat tour through the arches.
The name "Kleftiko" comes from the Greek word for thieves. For centuries, pirates used these caves as a hideout, anchoring their ships inside the rock walls where they could not be seen from open water. Narrow entrances and deep chambers made the inlets nearly impossible to reach by force. The ships are long gone, but the name and the stories stayed with the coastline.
Today, swimmers float beneath the same arches that smugglers once used to disappear. Navy Blue features Kleftiko as a highlight on every South Cruise, offering an unhurried view from the deck of a modern open-yacht.
Visit Kleftiko with Private Charters, Shared Boat Tours, Sea Transfers, and Multi-Island Cruises
Private Kleftiko Boat Tours
A Private Boat Tour to Kleftiko reserves the entire luxury yacht for your group alone, with a dedicated local crew. Travel along the volcanic southern Milos coast, swim through sunlit sea caves and stone arches, and anchor in turquoise coves away from other boats.
Half-Day or Full-Day charters aboard the Sea Ray, Ryck, Raptor, or Navygon include chef-prepared Mediterranean meals, a premium open bar, paddle boards, snorkeling gear, and fresh beach towels on board. Your captain confirms the final route with you on the morning of departure.
Small-Group Kleftiko Boat Tours
A Semi-Private Cruise to Kleftiko welcomes a small group of up to 16 guests aboard the Raptor Open-Yacht. Morning and Sunset boat tours run from May through October, tracing the southern Milos coast at a relaxed pace with friendly company on deck throughout.
Mediterranean meal boxes are served between swim stops alongside a premium open bar, snorkeling gear, and paddle boards on board the yacht. Your captain follows the South Cruise route depending on sea conditions, with calm anchorage inside Kleftiko's largest cove and arches.
Direct Transfers & Multi-Island Trips
A Direct Sea Transfer connects Milos to nearby Cyclades islands aboard a premium yacht, without ferry queues or fixed schedules. In this boat trip, Kleftiko's white cliffs and stone arches offer a last view before open water, on the way to Santorini, Mykonos, Paros, and more Aegean destinations.
A Multi-Island Transfer gives you the option to combine up to five islands in one journey before reaching your final destination, with chef-prepared Mediterranean meals and a premium open bar on board. Travel to islands like Mykonos and Tinos and the rest of the Cyclades.
Island-Hopping Boat Trips in the Cyclades
A Multi-Island Cruise opens with Kleftiko as the southern highlight, then crosses to up to four Cyclades islands on a single Full-Day boat tour. The white cliffs and stone arches set the scene as the route continues to Poliegos, Folegandros, Sikinos and Santorini before returning to Milos.
Navy Blue runs five curated routes planned around the weather and your group's pace. Every full-day voyage brings chef-prepared Mediterranean meals, a premium open bar, snorkeling gear, and paddle boards. The hours move between swimming, sunbathing, and easy open water cruising.

Everything you need to know about our boat tours to Kleftiko in Milos
Kleftiko is reachable only by boat. The fastest way is a half-day or full-day boat tour from Agia Kiriaki, Navy Blue's departure point on the south side of Milos. No roads lead to Kleftiko, where the cliffs rise directly from the sea on the southwestern tip of the island.
Navy Blue runs three cruise options that reach Kleftiko: a Private Cruise on the South Route for full flexibility, a Semi-Private Cruise for smaller budgets, and a Multi-Island Cruise that pairs Kleftiko with Kimolos and Poliegos. If you're arriving from another Cycladic island like Santorini, Mykonos, or Paros, a Sea Transfer through Navy Blue can include a swim stop at Kleftiko along the way.
Yes. Swimming at Kleftiko is one of the main reasons travelers book a boat tour to this part of Milos. The water inside the coves is calm, shallow, and exceptionally clear, with sheltered chambers between the rock arches that stay protected from open sea swells throughout the summer season.
Most swim stops happen at the entrance to the larger arches, where the seafloor is sandy and visible. Snorkeling gear is included on every Navy Blue cruise to Kleftiko, and the rock walls below the surface host small fish, sponges, and the occasional school of bream. Cliff jumping is possible from the lower platforms for confident swimmers, though our crew always confirms conditions before guests enter the water.
Navy Blue cruises to Kleftiko start at 160€ per person on a Semi-Private half-day cruise, or from 950€ for a Private Cruise that reserves the entire yacht. Multi-Island Cruises that include Kleftiko start from 1,250€ for the yacht plus 50€ per guest for meals and open bar. Fuel costs apply on Private Cruises (300€ for South or North Cruise).
The final price depends on your group size, cruise length (half-day or full-day), and whether you're booking a Multi-Island Sea Transfer that adds Kleftiko as a stop. Every Navy Blue cruise includes a professional local crew, chef-prepared Mediterranean meals, an open bar, and snorkeling gear. For the most accurate quote, contact our team with your group size and preferred date.
A half-day cruise to Kleftiko takes about 5 hours and includes 4–5 swim stops, with Kleftiko typically as the main stop. A full-day cruise lasts 8 hours and adds 7–8 stops, often pairing Kleftiko with nearby destinations like Tsigrado, Gerakas, or Sikia Cave along Milos' southern coast.
Half-day cruises depart from Adamantas at 09:30 (morning) or 15:30 (sunset), giving you enough time inside the Kleftiko caves and a Mediterranean meal on deck between stops. Full-day cruises depart around 11:00 or at a custom time arranged with your captain. Multi-Island Cruises that include Kleftiko run 8 hours and visit up to four islands across the Cyclades in one day.
Boat tours to Kleftiko run from May through October, when the Aegean is calm and the water inside the coves is at its clearest. June, July, and August offer warm sea temperatures around 23–25 degrees Celsius, with light morning winds and full daylight for swimming through the arches.
Peak season runs through July and August. May, June, and September often offer better light for photography and quieter coves with fewer boats nearby. Kleftiko sits on the southwestern tip of Milos, and the South Cruise route is recommended when north winds prevail. Your captain confirms the route on the morning of departure based on sea conditions, with Kleftiko typically included whenever weather allows.

Booked a private cruise to Kleftiko for our anniversary. The captain took us inside the caves early before other boats arrived, which made the whole thing feel private. Swam through the arches, had Mediterranean lunch on deck, and found a quiet cove for the afternoon. Worth every penny. Highlight of our Milos trip.

Eight of us on a private boat tour to Kleftiko for a friend's 40th. Started early at Kleftiko before the heat, swam through the arches, then moved south for paddleboarding and lunch. The crew handled music and food without being in the way,nice balance. Got some incredible photos inside the caves. Already talking about doing another one in Milos next summer.

Navy Blue made our family boat tour unforgettable. Captain detoured through Kleftiko's deepest caves just for our kids. Safe, fun, full of wonder. The crew even helped our youngest with snorkeling. Best Milos experience.

Booked the sea transfer from Milos to Paros and asked to stop at Kleftiko along the way. Captain built in a 40-minute swim stop at the caves. Best way to move between islands in the Cyclades.

Solo traveler, joined the shared cruise to Kleftiko. Small group, plenty of space on deck, no pushiness about activities. Floated through the caves in peace. Good choice for anyone going alone.

Honeymoon cruise to Kleftiko. Champagne on ice when we boarded, captain found us a quiet cove for a swim, crew stepped back when we wanted time to ourselves. Sunset back into Agia Kyriakh was incredible. Glad we chose Navy Blue for this.

Early morning departure from Agia Kiriaki. We reached Kleftiko before any other boats had arrived. Swam inside the arches in silence, then continued to Poliegos for Blue Bay. Felt like we had the whole coast to ourselves. Worth getting up early.

By far the best private cruise in Milos! We booked a custom trip and saw places only reachable by boat. A true luxury experience in Greece without the lofty price. Amazing day!
