Milos boat cruise to Kleftiko and Sykia: 5 hours, 4 stops

Swim inside sea caves and anchor at Kleftiko's colored rocks

A half-day boat cruise from Milos visits four coastal stops in five hours: Gerakas beach with warm volcanic waters and cave formations, Tsigrado with its white sand slides, Kleftiko's transparent waters and small caves, and Sykia cave where the boat enters the cave mouth itself. The skipper provides live English narration. Snorkeling gear, water, snacks and a sun tent are included. You pick between a six-person or eight-person boat at checkout.

Step-by-step itinerary

Boat cruise exploring Milos beaches and caves

• Stop at Tsigrado beach and climb sand slides

• Enter Sykia cave for swim and photos

The experience

The cruise departs from Agia Kyriaki Beach and heads first to Gerakas, a boat-only beach backed by the volcano and lined with caves that steam from geothermal activity: the waters here run warmer than elsewhere on the route. White sand slides lead down to the shore, and the rock faces show the distinctive color bands Milos is known for. From there the boat moves to Tsigrado, a small turquoise cove accessible by land or sea. If you've hiked down the sand slides with a rope, you'll recognize why arriving by boat feels like a shortcut to a private beach.

Kleftiko is the centerpiece. The boat anchors long enough for a swim and photos among small caves carved into beautifully formed rocks. The water is so clear you can see the seafloor from the deck. The blend of rock color and water shade creates the kind of view people describe as a memory rather than a moment. After Kleftiko, the route finishes at Sykia, where the cave mouth is wide enough for the boat to motor inside. Sunlight filters through the opening and turns the water inside an emerald color, and you get another chance to swim and photograph the rock formations.

The boat carries either six or eight passengers depending on which vessel you book. Snorkeling equipment, bottled water, soft drinks, snacks and a full sun tent are provided. The skipper narrates in English throughout. The whole route takes five hours from start to return.

Top questions

What happens if it rains?

It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.

What makes Gerakas different from the other beaches on this route?

Gerakas is accessible only by boat and sits below the volcano Agia Kyriaki, with caves that release steam from geothermal vents. The water here is noticeably warmer than at other stops, and the rock formations show vivid color bands.

Can the boat actually go inside Sykia Cave?

Yes, the cave mouth at Sykia is large enough for the boat to enter. Sunlight filtering through the opening illuminates the water inside in an emerald color, and you can swim and take photos from inside the cave itself.

Is snorkeling gear included, or do I need to bring my own?

Snorkeling equipment is provided as part of the cruise. You don't need to bring any.

How long does the boat stop at Kleftiko?

The boat anchors at Kleftiko long enough for you to swim among the small caves and take photos, though the exact duration depends on conditions and the group's pace.

What's the difference between the two boat options?

You choose between a six-person boat (Wave 6.10m) or an eight-person boat (Evripus 8.55m) at checkout. Both follow the same route and include the same stops and amenities.

Do I need to be a strong swimmer for this cruise?

The cruise is suitable for all physical fitness levels. You can swim at each stop or stay on the boat. Snorkeling is optional, and the skipper adjusts the pace to the group.
