Greece "Fantastic boat trip! Nice fast boat with only a few people. Opportunity to swim through the caves and also relax time on the island. There was some confusion about my pick up at the hotel, but there was quick communication and switching."

Austria "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!"
