More ways to explore the area's outdoor wonders
A low-slung catamaran slips away from the caldera mouth as the white villages of Santorini slide up the cliff like postcards. The sea smells of salt and hot rock; the boat’s wake carves a clean path past rust-red cliffs and black basalt coves while the sun leans toward the horizon. Onboard, the deck hums with quiet anticipation—glasses clink, towels drape over railings, and the captain eases into a steady, easy pace.

Sun protection is non-negotiable
Bring high-SPF sunscreen, a wide-brim hat and UV-blocking sunglasses—the Aegean sun is intense and reflected off cliffs and water.
Bring motion-sickness remedies
If you’re prone to seasickness, take preventive medication or use acupressure bands before departure; the catamaran is steady but open water can swell.
Pack a reef-safe swimsuit and water shoes
Swim stops include rocky shorelines and volcanic sand; water shoes make entry easier and reef-safe sunscreen protects marine life.
Timing for photos and crowds
Aim to be on deck 30–45 minutes before official sunset for the best light and clearer views; smaller groups move quicker between swim stops.
High-SPF reef-safe sunscreen
Protects skin and local marine ecosystems during long sun exposure on deck and in the water.
