Glide the caldera aboard a small catamaran to swim in volcanic hot springs, anchor beneath the Red Beach cliffs, and finish with a Greek BBQ and open bar as the sun drops behind the caldera rim. This 4–5 hour cruise blends geology, swimming stops and local flavors in a compact, comfortable outing.
More ways to explore the area's outdoor wonders
The catamaran slips away from Santorini’s shoreline and the caldera cliffs open like pages of a sea atlas: white cube houses perched above volcanic rims, blue domes blinking in the sun. Guests settle on deck as the boat angles toward Palea Kameni, the twin islets that still breathe warm sulfur into the Aegean. The water pushes gently at the hull; the steam of the thermal bays seems to beckon you closer.

History
Santorini’s caldera was formed by a massive Bronze Age eruption (the Minoan eruption) that reshaped the island and left the multi-colored volcanic cliffs visible today.
Conservation
The caldera and surrounding waters are ecologically sensitive—use reef-safe sunscreen, avoid touching marine life, and follow crew guidance to minimize anchoring impacts.

Confirm pickup time
Pickup windows vary by hotel location—confirm your exact pickup time after booking to avoid missed transfers.
Pack for sea conditions
Bring a lightweight wind layer and non-slip shoes—late afternoons on the caldera can be breezy and decks wet.
Prepare for swimming access
Swims are from anchored deep water; reef shoes and a snorkel mask make rocky entries and exploring underwater easier.
Motion-sickness precaution
If you’re susceptible, take preventative medication or choose a morning cruise when seas are typically calmer.
Swimsuit (dark-colored recommended)
Essential for swimming, and dark colors are advised because sulfurous water can stain light fabrics.

Reef shoes or water shoes
Protect feet when entering from rocky shores or jumping into uneven seabed at anchored stops.
