During our holiday mid July 14, we had the chance to be hosted by Mario's glass bottom cruise. For us as family with teenagers, it was a great chance to spend an pleasure full day. Short time feeling as for the full day program Mario did show us several places, as many caves but also the public area at the turtle island. Very careful and under hugh respect on the turtles, Mario does know where to drive his boat as to participate but also to show those very curious looking turtles. Also we had the chance to go for swim and snorkel around as much as we wanted (..and where it was adapters to go..) and there for it became a very complete day of enjoy and pleasant. Although Mario was even so friendly and very helpful to the family on the same trip with small kids (...even one baby 10 month..) to give some space and time to keep all participants together. You really will go with Mario on his cruises and to discover the south part of Zakinthos, with his very personalized service. Cheers
