Introduction: What You Can Expect from This Speedboat Tour

This 2.5-hour adventure around Zakynthos begins with a convenient hotel pickup—no fussing about how to get to the boat. You’ll be transported to Agios Sostis Harbor, where your semi-yacht speedboat awaits. From here, the real fun begins as you glide through the Ionian Sea, getting up close with some of the island’s most treasured sights.

What’s great about this experience? First, the wildlife focus. The tour is designed to spot loggerhead sea turtles, which are a protected species in the National Marine Park of Zakynthos.
