Full Day Boat Tour to Kleftiko & Sykia Cave: An Honest Look at This Milos Experience
Planning a trip to Milos? If you’re craving a day on the water exploring some of the island’s most iconic spots, this full-day boat tour might be just what you need. It promises a scenic journey through crystal waters, visits to spectacular caves and beaches, and plenty of chances to swim and relax. While the price might seem steep at around $150 per person, the reviews suggest it offers a memorable, worthwhile experience—especially if you love being out on the sea.
What we particularly like about this tour is how it combines stunning natural sights with the warmth of a friendly crew. The guides are praised for their professionalism and knowledge, adding value beyond just a boat ride.

If you’re after a well-organized, intimate boat trip that gives you access to some of Milos’s most photogenic and historic spots, this tour is likely to fit the bill. It’s especially popular among travelers looking for a mix of adventure, comfort, and informative guidance.

Cape Vani: The Manganese Mine
Your first stop is the Cape Vani area, home to former manganese mines. The landscape here is surprisingly peaceful, despite its industrial past. The rocky, red cape offers a striking contrast against the blue waters, making it a favorite for photos. With just about five minutes here, it’s mainly a quick stop to admire the scenery and get a sense of Milos’s diverse history.

Return & Reflection

The Vibe & Onboard Experience

From the reviews, it’s clear that the crew makes a big difference. Guests consistently mention how professional, attentive, and friendly Costa, George, and the rest of the team are. They’re eager to share insights about the landscape and Milos’s history, making the boat feel more like a floating friends’ gathering than a tour.
Food and drinks are a highlight—complimented as generous and tasty. Snacks, meals, and an open bar ensure you’re well-fed and hydrated, which is crucial when spending hours out in the sun and sea. One traveler mentioned they brought plenty of sunscreen and towels, which is wise, especially since the water can be quite cold—so don’t forget a jacket or a blanket if you tend to get chilly.
For photography enthusiasts, the waterproof camera is a nice touch, allowing you to capture long-lasting memories without worry. The snorkeling gear is also a plus if you want to explore beneath the surface, although be prepared for cold water inside the caves, especially in May, as one review pointed out.
Practical Details & Value

At $150.39 per person, this tour offers a comprehensive day out that balances sightseeing, swimming, and cultural moments. The small group size — capped at 18 — means more personalized attention and space to enjoy the scenery.
The tour operates with flexibility—free cancellation up to 24 hours in advance, which is helpful if weather turns unfavorable. The weather-dependent nature of the experience means you might find some days more suitable than others, especially for cave exploration and swimming.
Given the positive reviews emphasizing great guides, delicious onboard food, and stunning scenery, many travelers find the price justified. It’s a full day of activities packed with visual delights, good company, and knowledgeable commentary.
Who Should Consider This Tour?

This experience is ideal for travelers who appreciate natural beauty, enjoy being on the water, and don’t mind chilly water inside caves. It’s well-suited for those who want a small, intimate group rather than a large cruise, and who value good food and professional guides. If you’re looking for a relaxed, picturesque day with light adventure and plenty of photo opportunities, this is a solid pick.
Not the best choice if you’re sensitive to cold or prone to seasickness, since the trip involves some open water sailing and cave visits. Also, if you’re after a quick sightseeing stop, keep in mind this is a full-day commitment.
