The experience

You board a traditional boat and spend the afternoon navigating Milos' most dramatic coastline. The crew sails past Klima village (where colorful boat houses called syrmata are carved into the rock), then along Cape Vani, where volcanic cliffs drop straight into the Aegean. The boat stops at Kalogries Beach first, a calm bay with turquoise water where you can swim or snorkel before moving on to the main attractions.

Sykia Cave is the centerpiece: a sea cave with a collapsed roof and crystal-clear water that the boat enters directly. You see the volcanic geology up close and can swim inside if the conditions allow. From there, the boat heads to Kleftiko, Milos' most famous landmark, where you explore sea caves by zodiac (a smaller inflatable boat), snorkel among rock formations, and swim in the turquoise water. The crew serves breakfast, coffee, lunch and drinks throughout the day, with local specialties and alcoholic beverages included.

The tour runs five hours and suits swimmers and snorkelers of any fitness level. Snorkeling equipment is provided, so you only need to bring a towel and sunscreen. The boat is crewed by locals who know the island's geology and maritime history, and they navigate the caves and beaches based on conditions that day.

Kleftiko offers both. You snorkel among the rock formations and sea caves, and the crew also takes you into the caves by zodiac, a smaller boat, so you explore them from the water. Snorkeling equipment is included.

How many stops does the boat make during the five hours?

The tour stops at four main sites: Kalogries Beach for a swim, Sykia Cave, Kleftiko Beach, and Firopotamos Beach. The boat also cruises past Klima village and Cape Vani so you see the full coastline.

Do I need to bring my own snorkeling gear?
