Zakynthos: Turtles, Marathonisi & Keri Caves Speedboat Tour

Imagine gliding across the shimmering waters of the Ionian Sea, with the sun warming your back and the chance to see wild loggerhead turtles in their natural habitat.

This particular tour, lasting around 2.5 hours, is a favorite among travelers seeking an authentic experience that combines nature, excitement, and some of the island’s most iconic sights.

What to Expect from the Speedboat Tour

Starting Your Adventure

Your day begins with a hotel pickup (if you choose that option), easing the often tricky logistics of organizing transportation. Then, you’ll head to Agios Sostis Harbor, the launch point for your semi-yacht speedboat. The boat is described as eco-friendly, which is a nice touch, showing respect for the environment you’ll be exploring.

Approaching the Marine Park

Once onboard, the fun kicks off with a thrilling ride across the waters toward the National Marine Park of Zakynthos.

As the boat approaches the turtles’ habitat, the crew guarantees you’ll get a close-up view — and many reviews confirm this, with travelers excited about the guaranteed turtle sightings.

One reviewer notes, “The tour started about 30 minutes late, but once underway, it was worth the wait.”

Analyzing the Value

At a price point that includes hotel pickup, a guided tour, and multiple swimming and photo stops, this tour offers considerable value for a half-day adventure.
