Had a very nice day. We were picked up at the hotel at the agreed time. Nice excursions to Kalamaki beach with explanation about the turtles. Nice boat trip to Keri caves and even saw a turtle. On the island of Marathonisi we swam for an hour and had a drink. Top!

The trip was a lot of fun for us. The organization worked flawlessly. Very quick response to messages/questions via email. The bus driver/guide was very friendly and guided the trip well and provided information. The boat captain was very personable and the boat trip was the highlight! Beautiful bays, Marathonisi island and the sea - just gorgeous! Only the long drive around the poor turtle was not that great and unnecessary.

While there was a bit of a delay with getting on the boat not the drivers fault, once on the boat we had a fabulous time. Plenty of opportunities to swim, we got to see a turtle and the driver was careful to not get too close. I thought it was a great day.
