Cruise the Santorini caldera on a private three-hour charter to Nea and Palea Kamení. Swim in thermal springs, snorkel crystal coves, and return to the boat for traditional Greek bites and local wine.
More ways to explore the area's outdoor wonders
The caldera opens before you as the boat eases away from the quay: black rock faces drop into cobalt water, and the air carries the mineral tang of steam. On a three-hour private charter from Fira you’ll cut across the Aegean toward the smoking heart of Santorini — the lava islets of Nea and Palea Kamení — where warm springs steam and hidden coves invite a swim.

History
Nea and Palea Kamení are volcanic islands formed by eruptions inside Santorini’s caldera; the islands and their deposits record the ongoing geological reshaping of the archipelago.
Conservation
The caldera is taxed by tourism; stick to designated landing areas, avoid littering or touching fragile sea life, and prefer boats that follow local waste and anchoring guidelines.

Bring an old dark swimsuit
Sulfur in the hot springs can stain swimwear; a dark or older suit avoids ruining favorites.
Use water shoes for shoreings
Palea Kamení and Thirassia have rocky landings—water shoes protect feet and improve grip.
Limit hot-spring time
Hot spring water is warm and mineral-rich; stay brief if you have heart issues or feel lightheaded.
Charge your camera and schedule late afternoon
Golden-hour light flatters the caldera and keeps seas calmer than midday; bring a waterproof case.
Old or dark swimsuit
