Santorini Catamaran Day Cruise to Caldera, Hot Springs & Red Beach
Spend a half-day catamaran cruise around Santorini’s caldera sampling hot springs, snorkeling off volcanic islets and visiting the Red and White beaches. This practical guide covers what to expect, local geology and how to prepare for the trip.
The Experience
Before You Go
Bring reef-safe sunscreen
Use biodegradable sunscreen to protect local marine life and reduce skin irritation after swimming in mineral-rich springs.
Protect your feet
Bring water shoes for uneven volcanic shorelines and pebble beaches like Red and White Beach.
Motion-sickness prep
Take preventative medication or acupressure bands if you are prone to seasickness—the caldera can be choppy with crosswinds.
Confirm pickup details
Contact the operator 24 hours before departure to confirm pickup location and provide required passenger passport information for port authorities.

Conservation Note
Santorini’s coastal zones are ecologically sensitive—avoid anchoring on seagrass beds, use reef-safe sunscreen and follow crew guidance to minimize impact on marine habitats.
Santorini’s caldera formed after a massive Bronze Age eruption that reshaped the island and influenced ancient Aegean civilizations; Akrotiri’s archaeological site preserves a Minoan-era town buried by ash.
