Operated by Dakoutros Bros J.V. · Órmos Athiniós, cyclades
Órmos Athiniós, a tranquil port in the Cyclades, serves as the gateway to one of Greece’s most dramatic landscapes—the volcanic Caldera of Santorini. Operated by Dakoutros Bros J.V., the Tour of Caldera & Sunset in Oia invites adventurers to embark on a 9-hour journey that marries the raw power of geology with refined coastal charm. The cruise departs from Órmos Athiniós on the Calypso Glass-bottom Boat, offering a rare vantage point of Santorini’s submerged volcanic craters and rugged cliffs sculpted over millennia.
The highlight of the voyage is the chance to swim in the island’s famed therapeutic hot springs. The warm, mineral-rich waters emerge from underwater vents along the caldera’s rim, promising a rejuvenating dip set against a backdrop of jagged black rocks and cobalt seas. Following a stop at the peaceful island of Thirassia, guests can unwind on beaches far less crowded than Santorini’s main shores, where the Mediterranean laps gently at volcanic sand.
As daylight wanes, the cruise circles Oia, famed for its whitewashed homes precariously perched above the sea. Disembarking, you’ll stroll through Oia’s narrow, winding lanes to watch the sunset—a natural spectacle renowned for painting the sky with shades of gold, pink, and crimson. This transition from sea to village provides a unique blend of adventure, natural beauty, and cultural immersion.
Dakoutros Bros J.V. has anchored itself as a standout operator in this iconic area by blending safety, comfort, and authentic local knowledge. Their glass-bottom boat offers an educational glimpse beneath the surface, while their attentive crews ensure travelers feel connected to both the landscape and its stories.
