More ways to explore the area's outdoor wonders
You push off from Heraklion Marina as the city slips behind — salt on your lips, rigging whispering, and the yacht carving a clean wake through the Aegean. The small band of islets known as Dia grows larger: sheer limestone cliffs, scrubby garrigue and a handful of secluded bays that look as if they were cut for swimming.

Protect against sun
Bring high-SPF sunscreen, a wide-brim hat, and sunglasses — reflection off the water increases UV exposure.
Watch for seasickness
If you’re prone to motion sickness, take medication 30–60 minutes before departure and pick a central seat on deck.
Respect anchoring zones
Avoid stepping into seagrass when entering or exiting the water; ask the crew where it’s safe to swim and anchor.
Bring a light layer
Even warm afternoons cool quickly at sea—carry a windbreaker for sunset sails.
Reusable water bottle
Staying hydrated under the Mediterranean sun is crucial during a half-day cruise.
High-SPF sunscreen & lip balm
Reflective water and prolonged exposure make strong sun protection necessary.
