I have fond memories of visiting Hydra as a child. We took a boat out to visit the island, soak up some sun, and cool off our toes in the water.
There are no cars, bicycles, or motorcycles on hydra and it is hilly, so if you want to get around, they offer donkeys.
For lunch we had some kebabs in pitas and fried zucchini balls. The star of lunch was the fries, which came with feta and oregano. It's really the best way to eat fries. Even better than truffle aoli. I don't have a lot of food porn photos. Usually I was just too hungry or too forgetful to take photos of what I was eating.
When I was a kid we used to get huge muffins on Hydra. I didn't find a bakery with muffins, but I did get a great piece of cinnamon cake. We saved the cake and ate it down by the water.
