Discover Zakynthos’ stunning coastlines, caves, and shipwrecks on an 8-hour boat tour with swimming stops, cave visits, and chances to see dolphins.
Exploring Zakynthos: A Closer Look at the Boat Tour with Cave Visits & Swim Stops
If you’re dreaming of a full-day adventure around Zakynthos, this boat tour promises an immersive experience with visits to iconic caves, the famous shipwreck, and plenty of time for swimming. The journey aboard the “Dolphin” is designed to showcase the island’s dazzling coastline, from the steep cliffs of the west to tranquil fishing villages and hidden caves.
One aspect many travelers appreciate is the scenic variety — you get to see everything from the turquoise Blue Caves to the historic shipwreck, all while enjoying the gentle sway of the boat. However, potential participants should consider that the reviews reveal some concerns about crowding and limited swim stops, which might impact the overall experience. This tour suits those looking for a structured day of sightseeing with some scenic highlights and don’t mind sharing the boat with a crowd.

This 8-hour boat tour provides a comprehensive snapshot of Zakynthos’ coastline and its most famous sights. Organized by CAVO GROSSO, it departs from Zakynthos Town at around 9:30 AM, with pickup options available — a helpful feature for travelers staying outside the immediate port area. The boat, called the “Dolphin,” is a central part of the experience, offering a chance to relax and enjoy the views.
The journey starts with a pickup from your resort or direct arrival at the main port of Zakynthos opposite Solomos Square. After boarding, the boat sets sail along the eastern coast, passing popular beaches like Tsilivi and Alykanas, giving guests a first taste of the island’s scenic beaches and lush surroundings.
The first highlight is the Blue Caves, which are renowned for the way sunlight streams through the water, casting purple, red, and turquoise reflections on the cave walls. This is often a photographer’s dream, and many travelers mention how spectacular the colors are. Some reviews note, however, that the crowding can detract from the experience, with many boats visiting the caves simultaneously.
Next, the boat heads south around Cape Skinari, where there’s a real chance to spot dolphins—a highlight for many. While sightings are not guaranteed, the chance to see these playful creatures in the wild adds a touch of excitement.
One of the most famous sights is the Shipwreck of Navagio Beach, which many travelers have seen in postcards. The boat stops here for approximately 1.5 hours, giving ample time to snap photos and even take a dip in the crystal-clear waters. Several reviewers found this stop to be the “main highlight,” describing it as a “breathtaking” and “iconic” moment of the trip. However, some mention that the crowds can be overwhelming, with the area packed with other boats.
Next, the boat moves on to Porto Vromi, a charming fishing village with two natural harbors. Here, you’ll see the “Face of Poseidon” carved into the rock, which is a fun photo opportunity. Many appreciate this stop as a chance to relax and enjoy the peaceful scenery.
The boat then visits the Dolphin Caves, a series of roughly 100 caves deep into the rocks, with three large caves accessible by boat. Some travelers reported that their guides were friendly and knowledgeable, making the experience more engaging. One of the larger caves allows for a quick stop for photos, adding to the fun.
The Keri Caves, located further south, are also on the itinerary. These caves extend deep into the mountains of Keri and are known for their stunning natural formations. After the caves, there’s a chance for a refreshing swim at Oasis Beach — a great opportunity to cool off after hours on the water.
Next, the famous Marathonisi island (shaped like a turtle) appears on the route. Many travelers look forward to this sight, especially because it’s a nesting site for Caretta-Caretta turtles. If lucky, you might spot one of these gentle giants, making for an unforgettable moment.
The tour includes stops at Mavratzi Beach or Gerakas Beach in Vasilikos, both known for their beautiful sands and clear waters. These are perfect for a swim or just unwinding for a while before heading back north.
As the boat heads back to Zakynthos Town, you’ll pass by beaches like Porto Zoro, Banana Beach, and Argasi, with plenty of photo opportunities. The day wraps up around 5:00 PM, and a coach will transfer you back to your accommodation.

While the tour offers amazing scenery and some iconic stops, reviews highlight a few pitfalls. Critics mention the overcrowded nature of the boat and stops such as Navagio Beach being “packed with travelers,” which can affect the serenity of the experience. One reviewer noted, “Too many people. Rude staff. The trip instead of ending at 5 pm ended at 3 pm. I do not recommend it.”
Plus, some travelers expressed disappointment with short swim stops and disgusting bathrooms onboard, which can detract from the comfort. On the other hand, many found the guides to be friendly and knowledgeable, which added value to the experience, especially when spotting dolphins or exploring caves.
While the possibility of dolphin sightings can be a hit or miss, the chance to see these creatures in the wild adds an element of excitement. The scenic views, especially at Blue Caves and Marathonisi island, are often described as breathtaking and worth the trip.

The value of this tour depends on your priorities. If you love seeing multiple natural attractions in a single day and enjoy scenic boat rides with photo opportunities, you’ll likely find this experience rewarding. It is well-suited for travelers who want a structured itinerary that hits virtually all the major sights with minimal effort.
However, if you’re sensitive to crowds or prefer more relaxed, less commercialized experiences, this might not be the best fit. The long hours on the boat and some reviews citing overcrowding suggest that quieter, more intimate tours could better suit certain travelers.

This boat trip is ideal for first-time visitors to Zakynthos wanting a rundown of the island’s highlights in one day. It’s also perfect for those who enjoy photography, as many stops offer fantastic views and Instagram-worthy moments.
If you’re traveling with family or friends who don’t mind a bit of busyness and crowds, this is a good choice. The inclusion of dolphin sightings (even if not guaranteed) and iconic sights like the Shipwreck makes it a memorable, if busy, adventure.
On the flip side, if you’re after a quiet, secluded experience or have mobility issues, consider alternative options or private tours that might offer more personalized attention.

In terms of value, the tour offers a full day packed with diverse sights—from caves and shipwrecks to beaches and dolphin spotting chances. The organized pickup and drop-off, combined with the opportunity to see Zakynthos’ most famous sights, make it a convenient choice for many travelers.
However, the crowd factor and some uncomfortable amenities could impact the overall enjoyment. It’s a good fit for travelers who prioritize seeing the main attractions without too much hassle and are okay with sharing the experience with fellow travelers.
For those who want a balanced mix of adventure and sightseeing and don’t mind some busy spots, this tour offers decent value. Just manage expectations around crowd size and swim duration — as these are common points in reviews.
