Planning a day on Milos Island and considering a boat tour? This private full-day experience offers a chance to see some of the most breathtaking spots in the Cyclades from the water. Although I haven’t personally been on this exact tour, I’ve studied the details and reviews to give you an honest, in-depth look at what you can expect.
What immediately catches the eye is how much knowledge the guides seem to have—they know the island like the back of their hand, promising a smooth and personalized experience. Plus, the itinerary is packed with eye-catching stops like secluded beaches, dramatic sea caves, and iconic rocky formations. That said, it’s worth noting that the price tag is quite steep, so understanding what you’re getting for your money is important.
If you thrive on discovering hidden gems away from crowds, love being on the water, and appreciate expert guiding, this tour could be a perfect fit. However, if you’re on a tight budget or prefer a more leisurely, less packed day, you might want to weigh the costs against the experience.

The Details of the Itinerary

Starting Point and Departure
Depending on your preferences, the tour can kick off either from Sifnos’ Platis Gialos marina or from Pollonia bay in Milos. The choice affects your initial cruise route, but either way, you’ll set sail early at 9:00 am, giving you plenty of time to explore.
- From Sifnos: The cruise crosses the Kimolos-Milos strait, passing Poliegos island’s northwest cape, then heading towards Milos’ sulfur mines.
- From Milos: The cruise heads directly south from Pollonia, arriving at the sulfur mines in less than 15 minutes.
First Stop: Sulfur Mines and Old Mine
The tour begins with a visit to Milos’ historic sulfur mines. This spot is free to visit and offers a glimpse into the island’s industrial past. The water here is tinged yellow from sulfur and is believed to have therapeutic properties—an interesting fact that many travelers find intriguing.
Authentic old machinery and factory remnants evoke scenes from a spaghetti western, providing both a photo-worthy and educational experience. You’ll spend around 20 minutes exploring and swimming if the weather permits.
Gerakas Beach: Secluded and Stunning
Next, the boat anchors near Gerakas Beach, accessible only by boat, making it a true hidden gem. Its crystal-clear waters and unspoiled scenery are often ranked among the top beaches in the Cyclades. You’ll love the relaxed vibe and the chance to swim in waters that look almost unreal in their transparency.
Tsigrado Beach and Cave Exploration
One of the most distinctive stops is Tsigrado Beach—the only beach in Milos that requires climbing a large wooden ladder to visit. It’s a quirky, memorable feature that adds a bit of adventure to the day. You can swim nearby in a very secluded spot away from crowds, with turquoise waters perfect for snorkeling.
Before heading to Gerontas Beach, the boat enters a large cave, which adds an element of exploration and excitement. Gerontas is known for its dark brown, fine sand and smaller private coves—ideal for those looking to escape the busy beaches.
The Iconic Kleftiko
No visit to Milos is complete without seeing Kleftiko, one of Greece’s most photographed landscapes. The group of strange, grey-white rocks and caves form an almost otherworldly scene. The boat anchors multiple times here, allowing you to swim through caves and explore caverns from different angles.
Many reviews highlight how special it is to snorkel in these caves, entering from one side and emerging on another. Expect to spend around an hour and 15 minutes here, soaking in the stunning natural sculptures.
Sarakiniko and the Fiords
The next stop is Sarakiniko Beach, famous for its moonscape-like cliffs and bright white volcanic formations. The scenery here is truly surreal—think of tall, whimsical cliffs that seem sculpted by the gods of geology. You’ll have about an hour to swim, jump from cliffs, and take pictures of the unforgettable landscape.
Optional Lunch at Mandrakia
If you’re hungry after all the swimming, the tour offers a chance to stop at Mandrakia, a charming fishing village with colorful syrmata houses. It’s a favorite among travelers for its delicious seafood and picturesque setting. You can enjoy a relaxed meal at a seaside tavern, soaking in the views of boats and rocky shores.
Final Stops and Return
The tour’s end takes you past Navagio (Shipwreck)—a famous underwater wreck visible at about 8-10 meters deep—before heading back east toward Pollonia Bay or, if starting from Sifnos, returning to Platis Gialos.
The entire experience lasts roughly 8 to 9 hours, giving enough time to see everything without feeling rushed.

Is It Worth the Price?
At around $2,291 for up to 8 people, this private tour isn’t cheap. But considering the personalized service, guided experience, and access to exclusive spots, it can be a good value for a special occasion or if you’re traveling in a group wanting a luxury,stress-free day.
The price essentially covers a full day of exploration, swimming, and sightseeing—activities that can be hard to organize independently. Plus, having a knowledgeable guide ensures you get the most out of each stop, making it more than just a boat ride.
Who Is This Tour Best For?

This experience is ideal for groups seeking exclusivity and a tailored adventure. If you love natural beauty, snorkeling, and exploring remote beaches, you’ll find your money’s worth. It’s also well-suited for travelers who prefer a more private, relaxing day without the chaos of crowded boat trips.
