More ways to explore the area's outdoor wonders
You step aboard a low, open console craft as the marina slips behind you and the caldera cliffs rise like copper pages of a map. The sea dares you forward; its clear blue pushes at the hull as Santorini’s whitewashed villages hold their balance above the drop. Ahead, steam-worn islets—Nea and Palea Kameni—mark the volcanic heart, while Thirassia waits with quieter coves and unhurried tavernas.
