Discovering Zakynthos from the Water: A Close-Up Look at the Private Boat Tour of the South Coast
When it comes to enjoying Zakynthos, the best way to truly appreciate its rugged coastlines and shimmering waters is from the deck of a boat. This private speedboat experience from Porto Koukla Cruises offers a chance to explore the southern coast at your own pace, with stops at renowned sites like the Keri Caves, Myzithres, and Marathonisi. It’s a compact adventure—lasting around 3 hours—that promises plenty of swimming, snorkeling, and scenic moments, all with the guidance of a knowledgeable local skipper.
Two highlights immediately stand out: the flexibility of the itinerary—since it’s a private tour, you can choose how long to linger at each spot—and the personalized service. The crew is described as warm and accommodating, sharing insider tips like secret swim spots and natural wonders that you wouldn’t find on a larger, more rigid tour. Plus, you get to pick between a larger 7-meter boat, ideal for families or groups, or a cozy 5.6-meter speedboat perfect for couples seeking intimacy and adventure.
A potential drawback I’d note is the tour’s duration—just 3 hours, which might feel quick if you’re eager to see everything Zakynthos has to offer. Plus, because the tour involves swimming and snorkel stops, it’s not suitable for those prone to seasickness. But overall, this experience offers good value for those craving a flexible, off-the-beaten-path way to enjoy the island’s natural beauty.

Embarking on the Zakynthos South Coast Private Speedboat Tour

What makes this tour special is just how flexible and personal it feels. You’re not bound to a big group or a rigid schedule. Instead, your skipper, a local expert from Porto Koukla Cruises, guides you along the coast, sharing tips and stories about the natural formations you see, like the striking Keri Caves and the dramatic Myzithres rocks.
The experience kicks off at Porto Koukla beach, a convenient starting point where you’ll meet your skipper and get a quick safety briefing. From there, the boat heads towards the first stop—the Keri Caves. Here, you’ll glide past towering cliffs and jagged formations that are best appreciated from the water. The guided tour includes a swim break, giving you a chance to dive into the cool water and marvel at the underwater clarity. Many reviewers mention how memorable it is to see the caves from this angle, especially if you love dramatic scenery.
Next, it’s on to the Myzithres—home to some of the most photogenic rock formations on the island. The white cliffs and vibrant blue waters create a striking backdrop for photos and underwater exploration. Again, there’s a swim and snorkel stop, perfect for taking advantage of the calm, clear waters. The skipper might share some local secrets about the area, like lesser-known rocks or hidden coves.
The final stop is Marathonisi Beach, also called Turtle Island, which gives you a chance for a relaxed swim in tranquil waters. Even if you don’t spot turtles, the marine life here is lively and colorful. The tour provides snorkeling gear, so you can explore the underwater world at your own pace. Many reviews mention how relaxing and scenic Marathonisi is, especially with the chance to lounge on its pristine sands.
Throughout the tour, amenities like a Bluetooth sound system, shaded areas, and a cool box with refreshments make the trip comfortable and enjoyable. The boats are equipped with safety gear, navigation systems, a water shower, and a dining table, all designed for a more enjoyable experience.
