The boat slips away from Athinios as the island’s high cliffs begin to glow—white villages, black volcanic rock and the open Aegean all framed by a low sun. Onboard a traditional wooden sailing boat, passengers move from the old port past the volcanic cone, the sea hissing with geothermal heat near the hot springs, and drop anchor at Thirassia’s quiet jetty where a taverna waits.

The boat slips away from Athinios as the island’s high cliffs begin to glow—white villages, black volcanic rock and the open Aegean all framed by a low sun. Onboard a traditional wooden sailing boat, passengers move from the old port past the volcanic cone, the sea hissing with geothermal heat near the hot springs, and drop anchor at Thirassia’s quiet jetty where a taverna waits.
Santorini’s caldera is a product of one of the eastern Mediterranean’s most violent eruptions roughly 3,600 years ago; the split rim you now sail produces steep cliffs and sheltered bays. The geology you pass—pumice beaches, basalt outcrops, sulfur-stained water—shaped local fishing and viniculture traditions, and small jetty tavernas like Captain John’s feed into a culture that values fresh seafood and slow dinners by the sea.
After swimming at the hot springs—warm, mineral-rich pockets near Nea Kameni—guests step ashore on Thirassia for a simple dinner with complimentary wine. The return trip times the sunset, turning the caldera orange and violet as the boat navigates back to Athinios.
Practical guide: this is an easy, well-supported outing of about six hours suitable for most travelers. Expect basic steps getting on and off the boat, possible wet swim exits, and a light sulfur scent at the springs. Bring swimwear, reef-safe sunscreen, water shoes, and a light jacket for the open-deck evening breeze. If you’re prone to seasickness, take precautions before boarding. For photographers and first-time visitors, sit starboard for uninterrupted caldera views as the sun drops behind the rim.
