Zakynthos: Small boat trip to Keri, Mizithres & Marathonisi

Imagine spending a day on the water, surrounded by the stunning landscapes of Western Greece. This 7-hour boat tour from Agios Sostis offers a mix of adventure, relaxation, and natural beauty, perfect for those eager to see Zakynthos from a different perspective. For just over $100 per person, you’ll explore Keri Caves, snorkel in the clear Ionian Sea, and even get a chance to see Caretta-Caretta turtles—a true highlight. The trip also includes a tasty local lunch, making it a well-rounded experience.

We particularly love the short, intimate boat trips that keep the experience personal and manageable, especially since the boats accommodate only 8-10 travelers. The chance to snorkel in pristine waters and spot sea turtles is genuinely exciting. The scenic views of the caves and cliffs are breathtaking and worth the trip alone. On the flip side, some may find the hasty driver mentioned in reviews a little less relaxing, so keep that in mind if you’re sensitive to quick-paced rides or prefer a more leisurely vibe.

This tour is ideal for adventurous travelers who enjoy the outdoors and want to see the coast’s natural wonders without spending all day on the water. It’s especially suited for those comfortable with small groups and eager to combine sightseeing with a hearty local meal.

What to Expect from Your Zakynthos Boat Trip

This tour starts with a convenient pickup from your hotel or meeting point, transported in an air-conditioned vehicle to the port of Agios Sostis. Once there, you’ll meet your small group of like-minded travelers and hop into a compact boat designed for 8-10 people. The focus on small groups means you aren’t lost in the crowd—you’re more likely to get personalized attention and the chance to ask plenty of questions.

The Itinerary Breakdown

Keri Caves are first on the list. These limestone formations are a favorite for their dramatic shapes and the way they reflect the sunlight. We loved the way the boat glides smoothly along the coastline, giving you plenty of chances to snap photos or simply soak in the scenery. Many travelers mention that the views here are truly breathtaking, with some noting that the skipper and tour operator receive high praise for their friendly, professional attitude.

Next up, the boat heads toward Marathonisi, also known as Turtle Island. This uninhabited spot is famous for Caretta-Caretta turtles, and there’s a good chance you’ll spot them swimming gracefully in the waters. The reviews say that spotting these turtles is a highlight, and it’s one of the reasons this tour appeals to nature lovers.

Swimming, Snorkeling & Wildlife

One of the biggest draws of this tour is the opportunity to swim and snorkel in the Ionian Sea. The waters are described as crystal clear, making it easy to see marine life below the surface. Whether you’re a seasoned snorkeler or a beginner, the shallow bays are suitable for all levels. Be sure to bring sunscreen, a towel, and your snorkeling gear—or rent some locally if you prefer.

While none of the reviews explicitly mention the quality of the snorkeling equipment, the chance to swim in such pristine waters and possibly see a turtle or two makes it worthwhile. You’ll also get a close-up view of the beautiful cliffs and caves from the boat, which many find more captivating than simply viewing from land.

The Lunch Experience

After working up an appetite, you’ll head to a traditional tavern near the harbor for a local lunch. The included meal features authentic Greek dishes, providing both sustenance and a taste of regional flavors. This is a great opportunity to relax, chat with your guide, and reflect on the morning’s adventures.

The Drawbacks & Considerations

While many travelers praise the professionalism of the tour operator and skipper, some reviews point out that the driver can be a bit hurried. If you’re someone who prefers a slower, more leisurely pace, this might be a minor concern. The small size of the boats is generally seen as a positive, creating a cozy atmosphere, but it also means that if you’re prone to motion sickness, you should prepare accordingly.

Another point to consider is the duration—while seven hours might seem long, a good chunk of this is spent on the water or enjoying the lunch break. If you’re not comfortable with boat trips or have mobility issues, this might be less suitable.

Who Will Love This Tour?

This experience is best for adventurous travelers who want to combine nature, sea life, and scenic views in one half-day outing. It’s ideal if you’re comfortable on small boats and enjoy snorkeling or swimming in clear waters. Families with children who are used to boat rides, or groups of friends looking for a fun, intimate day on the water, will find this especially appealing. If you’re a turtle enthusiast or simply want to see Zakynthos from the sea, this will check many boxes.

Final Thoughts

This small boat trip from Agios Sostis offers a wonderful way to explore Zakynthos’ natural marvels. The chance to see the iconic Keri Caves, swim in the Ionian Sea, and spot Caretta-Caretta turtles makes it a memorable outing. The inclusion of a local meal adds authentic flavor and a relaxing end to a busy day.

While the driver’s pace might feel a bit hurried to some, the stunning scenery and intimate group size compensate well. It’s a value-packed experience for those who want to combine adventure with comfort in just a few hours.
