Discover Zakynthos' stunning coast with a private boat tour—swim with turtles, explore caves, and enjoy untouched beaches in a flexible, personalized experience.
Zante Private Boat Tour: Keri Caves, Mizithres, Agalas (max5)
Exploring the southwestern coast of Zakynthos via a private boat is one of those experiences that promises both adventure and tranquility. This five-hour journey, led by a friendly local skipper, offers a chance to see the island’s best-kept secrets—turtle hotspots, dramatic caves, and secluded beaches—without the crowds. It’s ideal for small groups who love personalized service and authentic natural beauty.
One of the standout features of this tour is its customizability. Since it’s a private experience, you can tailor the stops to your preference, whether that means more time swimming, exploring caves, or simply relaxing in peace. The chance to spot loggerhead turtles, swim in turquoise waters, and visit breathtaking sites like the Cave of Love makes it a memorable trip.
However, a consideration to keep in mind is that this journey is quite dependent on weather conditions, as the whole adventure takes place on the water—so a calm day will make all the difference. This tour is best suited for travelers who prioritize flexibility, stunning scenery, and a mix of adventure and relaxation in a small, intimate setting.


Your adventure begins at Calypso Boat Rentals, conveniently located at Limni Keri (Keri Beach). The meeting spot is easy to find—look for the large “Calypso” flag and a brown umbrella near the Rock Cafe. The staff, praised for their friendliness and professionalism, sets the tone for an enjoyable day. The boat itself is private, typically accommodating up to five guests, which promises a cozy, personal atmosphere.
The tour kicks off with a 40-minute visit to the National Marine Park of Zakynthos. This is not just a scenic cruise but also a chance to observe marine life. As many reviews highlight, loggerhead turtles (Caretta caretta) are often seen in this protected zone. One guest from Hungary mentioned their guide, Justin, was especially attentive and patient when spotting the turtles, which can sometimes be elusive. Keep your camera ready—these turtles are slow and graceful, and catching them in action is a highlight.
Next, the boat heads toward Marathonisi Beach (also known as Turtle Island), where you can opt for a swim or simply enjoy the beauty of the surroundings. The water here is crystal-clear and perfect for a refreshing dip. The reviewer from Switzerland called this part “an unforgettable experience,” noting the peaceful vibe and the chance to relax in nature’s lap.
From there, your guide will take you around the Keri Blue Caves, a must-see for anyone interested in geology and stunning vistas. These caves are accessible only by boat, making them one of the tour’s main attractions. Reviewers have appreciated the skill of their guides—who expertly navigate the boat into the caves, often circling back to give perfect photo opportunities.
The Mizithres Rocks are a highlight for many. These unique formations are perfect for snorkeling and swimming, and many guests found that the calm waters allowed them to explore at their leisure. The reviewer from Romania appreciated that their guide, Giannis, was able to take them beyond typical tourist routes, ensuring they saw hidden arches and took memorable photos.
The Eros Cave (Cave of Love) is famed for its vibrant turquoise color. It’s a short stop but a picture-perfect moment. The caves of Agalas are another scenic highlight, offering more secluded spots for swimming and photo ops. These stops often last around an hour, giving ample time for snorkeling and relaxing.
One of the most “Maldives-like” spots on this tour is Piscines Beach, accessible only by boat. The shallow, turquoise waters here are ideal for lounging or snorkeling. The Blue Lagoon near Plakaki (Agalas) is another tranquil paradise where you might find yourself completely alone. Guests consistently praise these spots for their untouched beauty and clear waters.
Since this is a private tour, the itinerary isn’t set in stone. If you want more time at a particular site or prefer to skip certain stops, your skipper can accommodate. Several reviews emphasize this flexibility—one guest appreciated starting their tour at 5 pm, enjoying the sunset and fewer boats on the water, making for a more peaceful experience.
The tour lasts about 5 hours, and costs around $590 per group (up to five people). Considering the personalized service, private guide, and access to otherwise unreachable spots, this price offers good value—especially for small groups seeking an intimate adventure. Included are masks, life vests, and fuel, which simplifies the planning. However, you’ll need to bring your own towels, drinks, and snacks.
