Great experience. Booked on the morning of through this website - didn't confirm as they weren't open until we arrived but we rocked up about an hour before our arrival so we could grab some breakfast. They checked us in as soon as we arrived. Would say if booking the morning of your trip dont expect a shuttle from your hotel - just make your own way there - less stress and loads of parking on the sea front and up the hill in the car parks (all free).

Excellent organization! Very friendly staff! :) We even drove a detour to see the turtles. Drop-off and pick-up were flawless. We would definitely use them again!

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!
