This was the only island i visited while i was in Turkey. It took about hour from Eminonu harbor to Heybeliada. Despite it was Saturday the island wasnt full of tourist so you could really enjoy explorig neighbourhoods and nature around island. If you want to completeley go around island it takes you 2 hours walking but its worth of it. I got some information from guards protecting some kind of object and from local people. The orthodox church ineae harbour is also beautiful with lot of decoration and religious icons. The only bad experience was that the churchkeeper because he was rude. He didnt allow me to see the liturgy held that day, even i was behind the doors. The other one was kind.
