Snorkeling in Milos: Kleftiko catamaran with sunset

The crew cooks lunch on the boat while you're still in the water at Kleftiko.

A half-day afternoon catamaran snorkel from Agia Kiriaki to Milos's most famous site, Kleftiko, where you swim and explore sea caves, then continue along the west coast with stops at Kalogries beach and the rock formations of Arkoudes before finishing at sunset. The route includes snorkeling equipment, a crew-prepared lunch served after your swim, refreshments and beverages throughout, and an English-speaking guide. The itinerary shifts with weather and the skipper's judgment.

The experience

You board a catamaran at Agia Kiriaki in the afternoon and sail south toward Kleftiko, the old pirate bay that anchors the whole trip. The water there is transparent enough to see the seafloor, and the site opens into sea caves you can explore while snorkeling. After you've spent time in the water, the crew serves lunch they've cooked on board, not a boxed sandwich, but something with real surprises. The snorkeling gear is included, so you arrive with nothing but a swimsuit.

From Kleftiko, the catamaran traces the west coast, passing the cave of Sykia with its collapsed ceiling, then stops at Kalogries beach for another swim. You'll pass Agios Ioannis, Triades and Agathia on the way. At Cape Vani, the boat turns to cross the bay, where Arkoudes (a cluster of lava rocks shaped like a bear) comes into view. The final stretch runs along the fishing villages of Skinopi, Klima, Areti and Fourkovouni, their colorful waterside houses called Sirmata catching the last light as the sun changes the sky.

The whole outing runs about six hours. Bring a passport. The operator needs your name, number, expiry and country before you board. Children from age 7 are welcome. If you need a vegetarian meal, mention it when you book. The route and timing can shift depending on weather and what the skipper decides is safest on the day.

Is this one for you?The afternoon departure suits a free half-day in Milos (you're back by evening), and the boat's pace is leisurely, with multiple swimming stops where you set how long to stay in the water. If you're new to snorkeling or prefer to ease into the day rather than start at dawn, this timing and the crew's guidance to the best spots work well.

What is Kleftiko and why is it the main stop on this snorkeling trip?

Kleftiko is Milos's most famous site, an old pirate bay with transparent water and sea caves you can explore while snorkeling. It's the centerpiece of the afternoon: the boat sails south specifically to reach it, and you spend the most time in the water there before lunch is served on board.

Do I need to bring my own snorkeling gear or is it provided?

Snorkeling equipment is included with the catamaran cruise, so you don't need to bring your own or rent it separately.

What happens if the weather is bad on the day of my booking?

The itinerary and timing can change depending on weather conditions and at the skipper's discretion. You'll be notified of any changes, and the route may be adjusted to keep everyone safe while still reaching the main swimming and snorkeling stops.

Lunch is included and cooked on board by the crew after your swim at Kleftiko. The operator describes it as full of surprises. If you need a vegetarian option, let them know when you book.
