Sylvie · FamilyNLNetherlands "For a larger group boattrip it is one of the best out here in Zakynthos. Because of the size of the ship you do not go into many caves but get really close. We got to see a turtle and they give you ample time for swimming in the dazzling blue oceans around the island. It is a 4 hour trip as stated in the booking. Definately recommend."

Connie · FamilyATAustria "I highly recommend Happy Days Zante. Great value for money, the company organises to pick you up from a convenient location in a small, clean charter bus. The boat was not over crowded and the sites visited by boat were amazing. This trip didn’t feel overly touristy, perfect for those who want to enjoy the sites without the big crowds. The stop over at the olive tree was also beautiful. We were then taken back to the original pick up spot. Amazing day!"
