Set sail from Heraklion for a relaxed half-day escape to Dia Island: crystal waters, Minoan ruins and sheltered bays for swimming and snorkeling. The small-group format mixes hands-on sailing with time to sun, swim and savor a local meal.
More ways to explore the area's outdoor wonders
A warm wind lifts off the Cretan Sea as the Heraklion harbor recedes and the island of Dia sharpens on the horizon. Onboard a small-group sailing boat the deck becomes a shared living room: some recline in the sun, others lend a hand with sheets and lines. The water here is clear enough to read the contours of the seabed as the coastline thins to rock and scrub.
