After boarding your catamaran at Ornos marina, listen to a safety briefing before you venture out onto the Aegean Sea. Head outside to laze atop the sundeck, and as the marina slips into the distance, enjoy views of unspoiled beaches and bays around the islands of Rhenia and Delos. If time permits, you'll stop in front of Delos to take photos of the island's archaeological site. Otherwise, you'll swim and snorkel at a cove known for its clear water and underwater delights. Sit down for a leisurely Greek lunch around midday, and savor a selection of salad and freshly grilled seafood and meat—all cooked on the catamaran by the chef. Beer, white wine, and soft drinks are available, too. With your meal finished, you'll return to Ornos, passing by the Greek islands of Naxos and Paros.
