If you want to visit Gokceada you definetly need a car to visit evrywhere properly. There is only one petrol station on the whole island. It is very close to center. On the way to Kuzuluk ferry marina to center. Make sure that u filled your car against bad surprises.
In derekoy district you may hear marmaros waterfall. the waterfall closed for public during the summertime due to fire risk. I visited this place with a private permission from the branch of Ministery of Forrests.
dont stay on the beach in ince burun night time
As it is kind of military area,it is forbidden to stay in ince burun beach after 20.00 o'clock.but it is not written!as we stayed there till 23.30 o'clock for searching a camping place,we stoped by the soldiers on the way back.they explained us later why it happended in the tourism office.Gokceada tourism information office will help for those who visit the island about eveything.it is in barbaros st,Kalekoy n:56and phone:02868874642.you should ask everyhing in the tourism office,if there is kind of forbidden areas like that.also same thing is possible for the Tepekoy cinaralti picnic area.You can't also visit Marmaros waterfall due to the fire risk.
The island has some bad roads so drive slow also all sort of animals like cows,goats,chickens,sheeps,donkeys that do not seem to follow the road traffic laws
Ask which areas you can visit (for example it is forbidden to enter marmaros forest without permission during the summer) or to photograph many parts of the island are consider as military areas
