The boat slips away from the port, lacquered white houses climbing the caldera above you while the sea opens into a broad, blue bowl. Salt spray hits your face as the wooden sailing boat points toward the dark, steaming spine of Nea Kameni — Santorini’s living volcano — and the day’s rhythm is set between short hikes, swims and shoreline lunches.

History
The caldera formed after a massive Minoan-era volcanic eruption; the islands you visit are the exposed remains and later volcanic cones of that event.
Conservation
The caldera and surrounding islets are geologically sensitive; stick to marked paths, avoid disturbing fumaroles and use reef-safe products to protect marine habitats.

Bring motion-sickness meds
Crossings to the volcano and return can be choppy; take medication before boarding if you’re prone to seasickness.
Wear water shoes
There’s no sandy beach at the hot springs — rocky entries and ladders make sturdy water shoes very useful.
Use reef-safe sunscreen
You’ll spend time swimming in clear Aegean water; choose reef-safe sun protection to reduce environmental impact.
Carry a light wind layer
Open decks can be cool even in summer, especially when the boat is moving fast across the caldera.
Swimwear
