A full-day cruise from Kardamena that links quiet St. Antonios, volcanic Nisyros and pumice-shelled Yali. Swim, explore a monastery and optionally visit an active crater—this route blends relaxed boat time with dramatic geology.
More ways to explore the area's outdoor wonders
You push off from Kardamena as the town blurs into low white roofs and the Aegean opens wider—salt on your lips, breeze steering the Captain Antonis toward islands that feel like different chapters of the same story. The first stop, tiny Agios Antonios, drops you into near-solitude: a single chapel, a few rocky inlets and water so clear it dares you to swim.
Difficulty

Duration
8 hours
Fitness Level
Should be comfortable with several short swims, boarding ladders and climbing about 200 steps on Nisyros if you choose to visit the monastery or crater.
Wildlife
History
Nisyros formed from volcanic activity in the Quaternary; Mandraki’s architecture reflects Venetian and Ottoman layers around a traditional Greek port core.
Conservation
Anchoring is managed to protect Posidonia seagrass beds; use reef-safe products, pack out plastics and follow crew guidance to minimize impact.

Arrive Early at the Port

Wear Water Shoes
Landings on rocky beaches and ladders into the sea are common—water shoes protect feet and improve traction.
Bring Cash for Extras
Souvenirs, coffee in Mandraki, and the optional volcano entry often require cash; ATMs on small islands can be limited.
