We had booked to go on the glass boat. But because we were there in early May, it was not available yet. So we got to go on a speedboat with 6 others! It was a great experience with a very good experienced guide. 100% worth the money!!

An incredibly fun boat trip with a great captain. A unique kind of boat with a glass bottom so you could see the turtles swimming beautifully. Dog-friendly!

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!
