We (two adults and an eleven year old boy) took the all-day Cave and Turtle Trip last thursday. Mario is a very nice guy and a seasoned captain. He navigates his comfortably small (24 passengers) boat into into several caves with ease and accuracy. We stopped to swim into some caves. Snorklers got ample time to explore the seabed on their own. Later we saw a lot of turtles surfacing up close and diving under the boat. Mario is an environmentalist and cares not to annoy the lovely caretta turtles too much. This trip ist absolutely family friendly, but the kids should be able to swim. Be prepared to stay in the sun for a whole day! Early booking is advised. We came back full of new knowledge, great memories and with a good conscience. This trip was the highlight of our two week Zante holiday!
