Featured Tour
The Half Day Boat Tour to Kleftiko Milos is your gateway to the island's most iconic seascape. Departing from Agia Kiriaki beach on the southern shore, you'll cruise past dramatic volcanic cliffs at Geraka, Tsigrado, Firiplaka, and Katergo before anchoring at the legendary Kleftiko rock formations. Spend over an hour swimming through ancient sea caves and snorkeling in electric-blue waters, then continue to Gerakas bay for a second refreshing swim stop. Throughout the journey, complimentary water, iced tea, frappé, local raki, and homemade Miloan treats keep everyone energized. Whether you lounge in the shaded lower deck or soak up the Aegean sun on the upper deck, this four-hour adventure is perfectly paced for families, couples, and solo travelers alike.




About This Tour
Kleftiko is widely regarded as the crown jewel of Milos, a labyrinth of white volcanic rock formations, hidden grottos, and impossibly clear turquoise water on the island's southwestern tip. This half-day excursion brings you there on a traditional wooden caïque, the kind of vessel that has sailed these waters for generations, giving the journey an authentic, unhurried character that larger tourist boats simply cannot match.
Setting off from the charming beach of Agia Kiriaki, the route hugs the rugged southern coastline, revealing geological wonders at every headland. Passengers get a leisurely first stop at Kleftiko lasting at least one full hour, leaving ample time to swim through cave tunnels, snorkel around submerged boulders, and photograph the soaring white cliffs. A second stop at Gerakas bay rounds out the itinerary with yet another swim in sheltered, calm water.
What truly sets this experience apart is the warm hospitality on board. The crew serves chilled water, iced tea, Greek frappé coffee, and a pour of local raki alongside homemade treats that reflect the traditional flavors of Milos — all included in your fare. With a manageable group size and a four-hour duration, the outing feels personal and relaxed rather than rushed, making it an ideal half-day escape from the island's popular beaches.
Travel Guide
Everything you need to know before you go
Packing smart for a half-day boat excursion makes a real difference to your comfort. The Aegean sun is intense even in shoulder season, so sun protection is non-negotiable. The traditional wooden boat offers both shaded seating and an open upper deck, meaning you can choose your exposure, but you will want sunscreen regardless. A light cover-up or sarong is useful when moving between deck levels where the breeze can feel cool.
Since you will be swimming at two separate stops, pack your snorkeling gear if you own it — exploring Kleftiko's underwater arches is far more rewarding with a mask and fins. Waterproof bags or dry pouches are handy for protecting your phone and camera while still keeping them accessible for photos. The crew provides drinks and snacks, so you do not need to bring food, but an extra water bottle for the journey to the meeting point is a good idea.
The adventure begins at Agia Kiriaki beach on the southern coast of Milos, where you board the traditional wooden caïque and meet your crew. As the boat pulls away from shore, the captain narrates the geology and history of each landmark you pass. The scenery escalates steadily — stark volcanic cliffs drop straight into the sea, sea caves come into view, and the water shifts through every shade of blue as you head southwest toward Kleftiko.
After roughly 30 to 40 minutes of sailing and sightseeing, the boat anchors at Kleftiko. You have at least one full hour here to swim freely through the caves, snorkel around the rock formations, or simply float and absorb the scenery. The crew serves refreshments on board while you relax. The second stop at Gerakas bay adds another half-hour swim in calmer, sheltered water before the boat returns to Agia Kiriaki, completing the four-hour circuit.
Agia Kiriaki beach is on the southern part of Milos, so plan your travel time from your accommodation accordingly. A rental car or scooter is the most convenient way to reach the departure point, though taxis are available from Adamas port. Arrive at least 15 minutes early so the boat can depart on schedule. The tour operates in suitable weather conditions only; in the rare event of strong winds or rough seas, the operator will contact you to reschedule or refund.
Children are welcome on board and the easy difficulty rating means no prior boating or swimming experience is required. That said, swimming at Kleftiko involves navigating around rocks and cave entrances, so basic swimming confidence is helpful. Non-swimmers are still welcome and can enjoy the scenery from the deck. The wooden boat is not a large vessel, so guests with severe motion sickness may want to take precautionary medication before departure, particularly if winds are moderate.
Traveler Reviews
See why travelers call this milos kleftiko boat tour the highlight of their entire Greek island holiday.
"Absolutely the best half-day we spent in Greece. The sea caves at Kleftiko were unlike anything I had ever seen — those towering white volcanic rocks rising straight out of crystal-clear turquoise water left us completely speechless. Our captain knew every hidden corner and even let us snorkel inside one of the larger caverns. The small group size meant we never felt rushed or crowded, which made the whole experience feel genuinely special."
"We booked this excursion on a whim and it turned out to be the single best decision of our Milos trip. The crew was incredibly knowledgeable, pointing out ancient pirate hideouts and explaining the geology of the rock formations as we sailed. Snorkeling equipment was clean and provided at no extra cost, and the water visibility was extraordinary — easily 20 metres down. I cannot recommend this trip highly enough for anyone visiting the island."
"Really fantastic morning out on the water — the scenery at Kleftiko genuinely lives up to all the hype you read online. The boat was comfortable and well-maintained, and the crew served refreshments which was a lovely touch in the heat. I docked one star only because the departure point was a little tricky to find without clearer instructions, so I'd advise messaging the operator the evening before. That small hiccup aside, the tour itself was wonderful and I'd do it again in a heartbeat."
"From the moment we left the harbour to the second we returned, everything ran like clockwork. The highlight was drifting silently through the sea arch while the morning light turned the water an impossible shade of blue — my photos still don't do it justice. Our guide shared fascinating stories about how pirates sheltered in these very caves centuries ago, which gave the whole experience a real sense of history. If you only do one activity on Milos, make it this one."
