This trip was one of the highlights of our trip to Crete. The boat was nice and spacious, we were 11 people including the captain and the skipper and there was enough space for all of us. The Dia Island itself was not too interesting, but it was a nice area to chill on the boat or swim (really blue, clear water!), although on the day we were there the water was a bit cold. The lunch was prepared fresh on the boat and it was amazing! I was kind of expecting a cold, simple dish but the crew went above and beyond to prepare a delicious warm meal for us. Big thanks to Dima and Mano - they were the best crew we could ever hope for. Friendly, funny, and they made sure every second we spent on the boat was comfortable. I would definitely recommend this trip - but make sure to bring warm clothes because it can get really windy on board!
