Board at the Santorini port for a concise, 3-hour boat tour to Nea Kameni and the Palaia Kameni hot springs. Hike to smoking craters and swim to thermal bays where 30–35°C water mixes with the sea.

You leave the port and the island's cliffs recline behind you; the caldera opens like a raw wound in the sea. The small motorboat threads through cobalt water toward the dark islets of Nea and Palaia Kameni. Steam lifts from cracked rock; the sharp smell of brimstone dares you closer as gulls wheel overhead and the boat settles near the volcanic rim.

You leave the port and the island's cliffs recline behind you; the caldera opens like a raw wound in the sea. The small motorboat threads through cobalt water toward the dark islets of Nea and Palaia Kameni. Steam lifts from cracked rock; the sharp smell of brimstone dares you closer as gulls wheel overhead and the boat settles near the volcanic rim.
The landscape here is recent in geological terms — Nea Kameni is the result of repeated eruptions that refilled the caldera formed after the Minoan eruption of Thera. Locals long prized the warm, mineral-rich waters and the thick volcanic mud for perceived therapeutic benefits. The climb to the active craters is short but raw: black scoria, steaming fissures, and clear views into the caldera where former eruptions reshaped the Aegean.
Practically, the tour is a compact, three-hour circuit designed for cruise passengers. Expect one stop near Nea Kameni with about 75 minutes ashore for photos and a short hike to the smoking vents. After reboarding you’ll anchor at the Palaia Kameni hot springs where water mixes with sea temperatures of roughly 30–35°C; passengers descend boat stairs and swim roughly 25–30 meters to the small thermal bay. The operator provides noodles and there are restrooms on board.
Bring water shoes and a towel, remain cautious around fumaroles, and avoid this excursion if you have cardiovascular concerns. Plan for sun exposure on the open deck and for stairs and short swims — it’s brief but decidedly elemental, an encounter with a living volcano and the warm waters it still feeds.
easy.
3 hours.
Suitable for most fitness levels; involves short walk to crater (uneven volcanic terrain) and a brief open-water swim.
The tour is approximately 3 hours; it includes guided stops at Nea Kameni (crater) and Palaia Kameni (hot springs), flotation noodles, and restrooms onboard.
Yes — passengers descend boat steps and swim roughly 25–30 meters into the small thermal bay; flotation aids are provided if needed.
The hike is short (about 30–45 minutes round-trip across uneven volcanic rock) and offers close views of fumaroles; wear sturdy footwear and avoid restricted fumarole areas.
Yes — the tour is designed for cruise passengers and departs near the port of disembarkation with quick embarkation using your e-voucher.
Nea and Palaia Kameni formed from post-caldera eruptions after the massive Bronze Age (Minoan) eruption of Santorini; the islands are active volcanic terrains shaped over centuries.
Stick to marked paths, avoid touching fumaroles, and use reef-safe sunscreen; the caldera’s fragile marine and volcanic habitats are sensitive to litter and chemical runoff.
