3 Hours Marathonissi Island Tour, Keri Caves and Turtles Spotting

If you’re dreaming of soaking up the beauty of Zakynthos from the water, this 3-hour boat tour offers a pretty decent way to do it. While it’s not a full-day adventure, it packs in enough highlights—like the charming Marathonissi Island, the dramatic Keri Caves, and the chance to spot the iconic loggerhead turtles—to make it worthwhile. It’s a trip that seems to appeal mainly for its scenic value and the opportunity to see marine life, especially if you’re pressed for time but still want a taste of the island’s best bits.

Two things we really like about this experience are the opportunity to see the local Caretta caretta turtles in their natural habitat and the visit to the Keri Caves, which are only accessible by boat. Both provide a sense of adventure and appreciation for the area’s natural beauty. That said, a potential downside is that some reviews mention issues with organization and crowding, which can impact the overall vibe—so if you prefer a very smooth, well-executed tour, this might not be perfect.

This tour probably suits those who love nature, wildlife, and scenic boat rides but aren’t expecting luxury or perfectly seamless logistics. It’s a good fit if you’re on a budget, want a quick yet memorable outing, or are traveling with a group that appreciates seeing turtles and exploring caves from the sea. However, if you’re looking for a more personalized or exclusive experience, you may want to explore other options.

The Itinerary: What You Can Expect

Marathonissi Island – The Turtle’s Breeding Ground

Your journey begins with a stop at Marathonissi, an island famed for its sandy beaches and importance as a breeding site for Caretta caretta turtles. This tiny island isn’t inhabited anymore but is a favorite for turtle spawning. You’ll get about an hour to enjoy the beach, which can be a peaceful retreat or a busy spot, depending on the day. One reviewer pointed out that Marathonissi can get crowded, which might lessen the serenity if you arrive during peak times.

The island’s charm lies in its natural state—no buildings, just the sound of waves and maybe some turtle sightings. We loved the way this stop offers a wild, untouched vibe, making it a lovely break from the more touristy areas.

Keri Caves – Sea’s Hidden Treasures

Next, you’ll head to the Keri Caves, accessible only by sea, which is where this tour really shines. These caves develop along the promontory of Marathia Cape and are a playground for photographers and adventurers alike. Some caves are large enough for boats to enter, while others are just accessible by swimming through narrow openings.

You’ll spend about 40 minutes here, which is enough to take in the views, snap photos, or even take a quick dip. The caves are impressive with their cliffs and arches, and many reviewers enjoyed the stunning scenery and the sense of exploration this section offers. One guest described it as an amazing place and appreciated the passage through rocky arches.

Turtle Spotting in Laganas Bay

The last part of your trip is dedicated to trying to spot Caretta caretta turtles in Laganas Bay. This segment lasts around 45 minutes. The turtles are still quite common, with some reaching impressive sizes—up to 140 kg or 120 cm in length, according to reviews. It’s fascinating to watch these creatures swim swiftly through the water, and guides are often skilled at pointing them out.

However, some reviews note that bad weather or crowded conditions can make spotting turtles tricky, and that the water can be busy at the stops, which could affect your chances of seeing wildlife. Still, many travelers report seeing at least one turtle, and the guides’ attentiveness makes the effort engaging.

The Group Size and Logistics

This tour caps at 23 travelers, which is a nice number for feeling like you’re part of a group but not overwhelmed. The boats are described as small, which can be cozy but also means space may be limited—some reviews mention feeling cramped, especially at swimming stops. The tour begins at 1:00 pm, with a meeting point in Laganas, and wraps up back at the same spot.

Pros and Cons based on Reviews

While many travelers praise the knowledgeable guides and the beautiful scenery, some have expressed frustration with disorganization at the harbor, where large groups get split and boats become crowded. One reviewer pointed out that they paid for a glass-bottom boat but ended up on a boat with a large hole—highlighting that not all experiences may meet expectations.

Price and Value

Considering the cost—around $30 per person—the tour offers a decent value, especially if wildlife and scenic views are your main goals. It’s a budget-friendly way to explore key coastal spots without the expense of private charters. But bear in mind, if the weather isn’t cooperating or if crowds are large, your overall experience might feel less special.

Who Should Consider This Tour?

This trip is best suited for nature lovers and wildlife enthusiasts who want a quick, scenic boat ride with opportunities for turtle sightings and cave exploration. If you enjoy a relaxed, group atmosphere and are okay with some logistical imperfections, you’ll find plenty to enjoy here. It’s also a good choice for travelers on a budget or those with limited time, looking to maximize their coastal experience without overcommitting.

However, if you’re someone who prefers a more organized, exclusive experience or has high expectations for comfort and smooth logistics, you might find some frustrations here. It’s not the most polished tour, but it’s authentic and offers good opportunities for memorable photos and wildlife encounters.

Final Thoughts

This 3-hour Zakynthos boat tour offers a solid overview of some of the island’s natural highlights. The chance to see the Caretta caretta turtles, explore Keri Caves, and relax on Marathonissi Island makes it appealing for a broad range of travelers. The price is reasonable, and with a knowledgeable guide, you’re likely to come away with some beautiful memories.

That said, keep your expectations flexible, especially regarding organization and crowd levels. If you’re okay with a bit of chaos and want a snapshot of Zakynthos from the water, this tour could be just right. It’s especially suited for those who really want to see turtles and enjoy scenic caves without spending a fortune or dedicating a full day.
