Sail out of Adamas for a full-day loop around Milos that mixes snorkeling in Kleftiko’s cave systems with a long swim at uninhabited Polyaigos. Expect volcanic cliffs, abandoned mine ruins and meals served aboard while guides share local history.
More ways to explore the area's outdoor wonders
Morning light breaks across Adamas harbor and the sailboats line up like expectant birds, rigging creaking as the captain shouts final checks. You push off into Aegean blues, the island’s volcanic cliffs receding while the guide points to white, pockmarked rocks where pirates once huddled. The sea here has a temperament: it nudges, it reveals, it keeps secrets in cave mouths.

Arrive early to the port
Adamas is small and the office sits across from the bus station — arrive 30 minutes before departure to check in and secure a good spot on deck.
Use reef-safe sunscreen
Protect coral and marine life during snorkeling stops; apply before boarding and reapply as directed.
Take basic motion-sickness precautions
If you’re prone to seasickness, take medication ahead of time and sit midship where motion is minimized.
Check ferry schedules if leaving same day
Ferry departures before 20:30 may conflict with this tour’s return—book later ferries or an extra night on Milos.
Mask & snorkel
A well-fitting mask makes snorkeling in caves and around reefs far more rewarding (some tours provide equipment).
