Zakynthos turtle spotting & swimming Tour with fully clear boat
Turtle spotting trip
A great trip , picked up and returned to hotel, 3 hours on a fairly large boat, plenty of space to sit in shade or on top deck. We saw a number of turtles on our trip but obviously not guaranteed. Visited Keri caves, chance to swim in the sea and then dropped off to sunbathe for an hour on turtle island and see active turtle nesting sites. All done with consideration for the wildlife I thought. Toilets on board were adequate . Remember to take own snorkels, water and snacks as none provided.

Zakynthos Glass Bottom Boat Tour to Keri Caves and Turtle Island
Reliable and flexible operator
We were informed ahead of time that our captain fell ill and were offered to move to a tour later in the day or the next day. Communications were clear and responses prompt. The trip was nice. We did see one turtle (in the Harbour already), but mostly enjoyed being out on the water and swimming in beautiful places.
