"The price was reasonable at €10.00 per person. Since the island was incredibly busy, we opted for a short visit. A text message was enough to get picked up again 10 minutes later. Other boats have a more extensive program with sightseeing stops and swimming stops. If you want more freedom, the boat taxi is a great option."

Elselien · CoupleNLNetherlands

"Great day! The program is well put together, an effort is made to find turtles. We swam wonderfully and enjoyed the beautiful surroundings. And... we also saw a turtle, despite it not being the right season. If you have the chance, sit at the front of the boat, wonderful! The captain makes an effort for his passengers, despite the fact that we were of course number 20,000!"

"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!"
