The catamaran slips from Adamas into a hard-blue Aegean that immediately feels colder and wilder than the harbor. Limestone cliffs peel away into sculpted stacks; the boat eases into a sheltered cove and the crew calls out a swim stop. Salt and citrus from a freshly prepared granola bowl linger as snorkel masks hit faces and the water invites you into underwater arches.

The catamaran slips from Adamas into a hard-blue Aegean that immediately feels colder and wilder than the harbor. Limestone cliffs peel away into sculpted stacks; the boat eases into a sheltered cove and the crew calls out a swim stop. Salt and citrus from a freshly prepared granola bowl linger as snorkel masks hit faces and the water invites you into underwater arches.
Geologically, Kleftiko’s dramatic cliffs and sea caves were carved by wave-driven erosion of Milos’s volcanic bedrock — the same island that supplied the famous Venus de Milo marble. The name Kleftiko (Thieves’ coves) hints at a violent past: sheltered caves once favored by pirates and smugglers. Today small fishing settlements and multicolored boathouses along the coast recall a working maritime culture that still supplies the boat’s lunch.
Expect three to four stops for swimming and snorkeling, a photo pass by the Cave of Sikia, and 45–105 minute windows to explore turquoise caverns at leisure. All food and soft drinks are included; local wine and beer served responsibly. Snorkel gear and swim noodles are provided, and the crew narrates myths and navigational notes as you float between limestone arches.
Practical guide: arrive 20–30 minutes early in Adamas, secure valuables in a dry bag, and test your mask fit before the first jump. If you’re prone to seasickness, choose the morning departure when seas are usually flatter and bring medication. Wear reef-safe sunscreen and water shoes for climbing on wet rock. Plan for sun exposure — the Aegean can be relentless — and enjoy the easy pace: this is a swim-and-sightseeing day that rewards curiosity more than endurance.
Yes — breakfast/brunch items, a cooked lunch using local ingredients, seasonal fruit, water, soda and age-restricted beer and wine are included in the trip price.
The trip is advertised as suitable for all fitness levels, but non-swimmers should remain cautious; flotation noodles are provided and crew assist with entries and exits from the water.
Adamas is Milos’s main port and easily reached by local bus, taxi, or a short walk from many island hotels; arrive 20–30 minutes early for boarding.
The operator notes wheelchair and stroller accessibility for embarkation; still, boat boarding and moving around the deck require basic mobility and supervision for young children.
