3 Hours Marathonissi Island Tour, Keri Caves and Turtles Spotting

Experience the Coastal Charm of Zakynthos with a 3-Hour Boat Tour

Imagine cruising along the sparkling waters of Zakynthos, Greece, in a glass-bottom boat, getting a glimpse of stunning sea caves, pristine beaches, and the chance to see the famous loggerhead sea turtles in their natural environment. For just under $30 per person, this 3-hour tour offers a compact yet memorable glimpse of the island’s most iconic sights. Starting in Laganas, you’ll visit Marathonissi Island, explore the Keri Caves, and enjoy some time spotting Caretta caretta turtles in the Laganas Bay.

Two things we especially appreciate about this experience are the opportunity to see the turtles in the wild, which is a real highlight for nature lovers, and the up-close view of sea caves and rocky formations accessible only by boat. The tour’s short duration makes it perfect for travelers with limited time, or those who want a quick but meaningful introduction to Zakynthos’s maritime beauty.

One possible drawback is the inconsistency noted in reviews regarding organization and boat capacity—some guests mention crowded boats and delays. If you’re sensitive to large groups or chaotic mornings, this is worth keeping in mind. Nevertheless, the tour’s value and authentic nature make it a good choice for curious travelers eager to see the local environment without spending a whole day at sea.

This experience suits travelers who appreciate wildlife spotting, stunning coastlines, and small-group adventures.

A Closer Look at the 3-Hour Zakynthos Boat Tour

What’s Included and How It’s Structured

The tour begins in Laganas, a lively resort area known for its beaches and marine environment. Meeting around 1:00 pm, you’ll head out on a glass-bottom boat, which immediately sets the tone for a relaxed yet visually engaging ride.

The first stop is Marathonissi Island, often called “Turtle Island” due to its role as a breeding site for the famous Caretta caretta turtles. This small, uninhabited island offers about an hour to swim and relax on its beautiful sandy beach. The fact that it’s a protected area highlights its importance for turtle breeding, making your visit both scenic and meaningful. One guest notes, “Nuotata nello splendido mare dela spiaggia di Keri,” emphasizing how delightful the sea and scenery are.

Next, the boat moves towards the Keri Caves, accessible only by sea, where you can admire spectacular rock formations and perhaps swim in the deep waters. The caves develop along Marathia Cape, with several large enough for entries or just viewing from the boat. The 40-minute stop provides opportunities for photos, exploration, and swimming. One reviewer calls it an “amazing place,” highlighting the impressive geology and secluded feel of the caves.

Finally, you’ll spend about 45 minutes in Laganas Bay hunting for sea turtles. The guide’s skill in spotting these animals becomes apparent here—one reviewer mentions, “Fik dog set en enkelt skildpadde,” which means they were lucky enough to see a turtle. These creatures can reach up to 120 cm in length and weigh around 140 kg, yet they’re surprisingly fast, reaching speeds of up to 30 km/h. Seeing them in the wild, especially in their natural breeding and feeding grounds, makes this outing truly worthwhile.

The Experience on the Water

The small group size (max 23 travelers) allows for a more personal experience, and the guides are often praised for being knowledgeable and friendly. The glass-bottom boat adds an extra dimension, letting you glimpse underwater life without getting wet—a real plus if you’re not keen on snorkeling.

However, several reviews mention issues with boat capacity and punctuality. One guest describes a boat with “a 1-meter square hole,” indicating some boats may be older or crowded. This can lead to a less comfortable experience if you’re sensitive to noise or crowded spaces. It’s a reminder that, even with a small maximum group, logistics can sometimes be tricky.

Navigating the Downsides

While most guests enjoy the scenery and wildlife, some found the organizing a bit chaotic—delays, overcrowding, or boats being full to capacity. If you’re someone who prefers a very structured, calm environment, these factors might affect your enjoyment. Still, the authenticity of the experience and the chance to see turtles in the wild often outweigh these inconveniences.

Value for Money

Considering the price of roughly $30, this tour provides good value. It covers diverse sights—beautiful beaches, impressive caves, and marine wildlife—all in a compact timeframe. It’s not a luxury cruise but offers a genuine taste of Zakynthos’s marine landscape. The inclusion of free cancellation adds flexibility, allowing you to adjust plans if weather turns unfavorable.

It’s a great option for travelers who don’t want a long day at sea but still want to see key sights.

However, those wanting a more luxurious or highly organized experience might prefer other options, as some reviews mention logistical hiccups.
