As it was the end of October and naturally, the end of the season, we were lucky to see one turtle come up for air shortly after we left the port. As it was an unusually warm October, the rest of the tour was enjoyable. The waters on Turtle Island were so clear, you could forget that it was also cold because the sun was dried it right off when you come out. The captain expertly guided the boat round and into caves and he made sure all sides of the boat got to see them and take the requisite selfies. One thing about the, though, was that it said wheelchair users can be on it. However, as a person using a cane, no ramp was provided to get in or out of the boat and had to use the regular stainless steel ladder like the rest of the passengers.

It was fantastic. The guide was very friendly and also waited for us although we came like 20 minutes late. The guide told us everything about all the islands and also the transfer was quick and very good. I can recommend everybody this tour because you see many things and also there is a very beautiful beach to go swim and take beautiful photos. Ten out of ten

So much fun. We got to see so many amazing views we wouldn’t have been able to see on our own and learned so much about the island that we didn’t know and authentic Greek food.

Fabulous trip, collected from hotel with ease and consisted beautiful island. No turtles as too late in the year but worth trip anyway for snorkelling in clear sea.

It was a miracle, I didn't expect it. Recommended to everyone
