Sail Santorini’s caldera on a five-hour small-group catamaran from Vlychada: snorkel in volcanic coves, soak in warm hot springs, and enjoy an onboard BBQ with an open bar. Ideal for travelers who want a compact, scenic sea excursion with local flavors.
More ways to explore the area's outdoor wonders
The catamaran slips away from Vlychada Marina and the island’s white cliffs compress into a ribbon of blue and stone. Salt fills the air; the caldera’s cliffs rise behind you and the boat’s gentle roll sets the pace for the next five hours of sea, sun and geology.

History
Santorini’s modern coastline was sculpted by the Minoan-era eruption and later volcanic activity at Nea Kameni; the caldera is a living record of those events.
Conservation
Avoid sunscreens with oxybenzone and steer clear of anchoring on seagrass beds (Posidonia); operators often follow routes that minimize disturbance to marine habitats.

Bring reef-safe sunscreen
Protect your skin and the marine environment—apply before boarding and reapply after swims.
Wear water shoes
Rocky shorelines and boat ladders are easier to navigate with grippy footwear.
Plan transfers if arriving by cruise ship
Tender boats land at Old Port Fira; you’ll need time to reach the operator’s office by cable car—allow at least an extra hour.
Hydrate and time your drinking
Open bar is included—pace alcohol intake and drink water between swims to avoid dehydration in the sun.
Swimsuit
