Milos stands out in the Greek islands for its stunning coastline, volcanic formations, and crystal-clear waters—perfect for snorkeling. Its rugged terrain means many of the best spots are unreachable by land, making boat tours the best way to experience the island’s underwater beauty. Among the many options, we particularly like the Milos: Half-Day Speedboat Cruise to Kleftiko with snorkeling tour. It offers a quick yet comprehensive look at some of Milos’ most iconic caves and beaches, with the added bonus of guided snorkels and drone photography—ideal if you want a snapshot of Milos without spending a full day at sea.
If you’re after a longer, more relaxed experience that combines multiple snorkeling stops with a more personal touch, the Round of Milos and Poliegos All-Inclusive Snorkelling and Cruise is worth considering. For those who prefer a more intimate, small-group adventure in a luxurious setting, the Milos caves snorkelling Catamaran Cruise in a small group provides ample space and included meals in an itinerary that explores both caves and beaches with fewer fellow travelers.
Below, I’ll go into detail about each of these top options so you can choose the best one for your style and expectations.
1. Milos: Half-Day Speedboat Cruise to Kleftiko with snorkeling tour

The itinerary also features a swim stop at Kalogries, a remote bay where snorkeling is organized for seabed exploration.
What makes this tour stand out is its focus on efficiency and access. Traveling by speedboat means you spend more time snorkeling and exploring than you would on larger, slower boats.
