Skirt Santorini’s caldera by private motorboat, hike the volcanic rim of Nea Kameni, soak in thermal springs and snorkel around the cliffed islet of Agios Nikolaos. This three‑hour excursion combines easy boat comfort with short, rocky onshore exploration.

A low-slung motorboat peels away from Ammoudi’s stone ramp and the caldera opens like a map of fire and sea. Salt air clips your face, the hull’s wake writing a bright line against volcanic cliffs, and you can already see the dark shoulders of Nea Kameni rising from the blue—steam whispering from old vents as the sea dares you closer.

History
Santorini’s caldera formed in a massive Bronze Age eruption that reshaped the island’s coastline; the current islets are products of more recent volcanic activity.
Conservation
The caldera’s volcanic soils and marine habitats are fragile—stay on marked paths, take all rubbish off the islets and avoid sunscreen contamination in sensitive shallows.

Footwear for volcanic rock
Wear reef shoes or sturdy trail sandals—the volcanic trail is sharp and uneven, and wet rocks are slippery.
Protect against reflected sun
Bring a high-SPF sunscreen and a wide-brim hat; sun reflects strongly off the water and pale cliff faces.
Hydrate before and after
Bottled water is provided, but carry extra if you plan to snorkel and hike—the dry wind and sun dehydrate quickly.
Motion-sickness preparation
If you’re prone to seasickness take medication or sit mid-boat where motion is gentlest during transfers.
Reef shoes or sturdy water sandals
Protects feet on jagged lava, slippery rocks and during water entry.
