★★★★★★★★★★4.5 · 2,053 reviews · 3 hours · from $29Our pick

Spend three hours in Zakynthos National Marine Park aboard a small glass-bottom boat with guides such as Dennis or Alexander. Look for Caretta Caretta turtles, pass through Keri Caves and the Kamares arches, swim in clear water, and stop at Marathonisi’s nesting beach. Pickup is available within 10 kilometers of Laganas.

“This tour was fantastic! Captain Dennis was an excellent guide and did his very best to make sure that we saw a few turtles! He kept circling around to give us the best view to see them. He took us to a swim spot in a secluded area which was beautiful and then we got to see the island which definitely was a highlight. It felt like you were in some exotic place. I would definitely recommend this tour!”

4.Turtle Spotting, Marathonísi & Keri Caves Cruise

★★★★★★★★★★4.2 · 780 reviews · 3h 30m · from $29

Set out from Agios Sostis on a 3.5-hour glass-bottom cruise with Zante Sun Travel. You will search for Caretta caretta turtles, swim near Marathonisi and Keri Caves, and stop at Mizithres Rocks. Captain Dennis and the crew are praised for careful boat handling, though the boat can feel crowded and its glass-bottom viewing panels are small.

“The boat was smaller compared to others which meant that there was more opportunity for us to see the turtles. Our captain was great and we had several opportunities to stop and swim. We managed to see the turtles and several sites.”
