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!

It was really good. They didn't follow the itinerary on point, but we had 3 swimming stops and we went to the shipwreck and blue caves so they delivered on what was promised.

The scenery was amazing. We even saw a turtle. The skipper was very experienced and had great control of the boat. Top-notch.

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!
