The experience

The catamaran leaves Milos bay and sails past the traditional fishing villages of Skinopi, Klima, Areti and Fourkovouni, where colorful stone houses called Sirmata sit built into the waterfront. You'll pass Arkoudes, a formation of lava rocks shaped like a bear, then head toward Cape Vani. The first swimming stop is the natural bay of Kalogries, where the water is clear enough to dive straight from the deck.

Next comes Sikia cave, where you can see the hole in its roof and the entrance from the water. Then the catamaran reaches Kleftiko, the old pirate bay, and you have two hours to swim and snorkel among the caves, white rocks and underwater rock formations. The crew knows which caves are best for each swimmer and will guide you through them. After the water, lunch is cooked on board and served to everyone.

The cruise ends at Agia Kiriaki. Light refreshments, water, coffee and alcoholic beverages are available throughout the day alongside the lunch. The program can change if weather turns or the skipper decides conditions call for a different route.

What’s included

• Light refreshments and bottled water throughout the day.
• buffet lunch cooked on board.

Is this one for you?This is a shared catamaran tour with a set schedule and a live guide, so it suits anyone who wants to reach Kleftiko's caves without renting a boat or organizing the route themselves. If you prefer to move at your own pace or want privacy, a private boat rental would be different, but this one keeps the cost down and puts the navigation and the lunch in the crew's hands.

What's actually inside Kleftiko that makes it worth the boat ride?

Kleftiko is a bay ringed with sea caves, white rock formations and transparent water where you can snorkel and swim for two hours. The caves are only reachable by boat, and the crew knows which ones are best for different swimmers and snorkelers.

How much time do I actually spend swimming versus sailing?

The cruise is six hours total. You stop to swim at Kalogries first, then spend two hours at Kleftiko in the water and caves. The rest is sailing along the coast and viewing Sikia cave from the boat.

Is lunch included, and what kind of food is it?

Lunch is cooked on board by the crew and served after you swim at Kleftiko. The description says it's full of surprises, though the specific menu isn't listed in advance.

Children are welcome from age 7. The tour is not suitable for children under 7 or for people with mobility problems.

What happens if the weather is bad on the day of the cruise?

The program is subject to changes depending on weather conditions and at the skipper's discretion, so the route or stops may shift to keep everyone safe.

Do I need to bring anything or know how to snorkel?

Snorkeling experience is not required. The crew will guide you to caves and help you explore. Bring a passport (the operator needs your name, number, expiry and country at booking for all participants).
