You reach Bozcaada by ferry. A pleasant half-hour crossing.
The ferry from the Geyikli pier in Çanakkale drops you on the island in about half an hour. Services are run by GESTAŞ.

By road: Geyikli is about a 4.5-hour drive from Istanbul. Our advice is to come via the Thrace side and cross the Çanakkale Bridge, which is both scenic and practical. From Bursa and İzmir it takes about 4 hours.
Once on the island, you'll get everywhere easily by car, bicycle or on foot, it's that small. And you won't have any parking trouble.
How to Reach Our Hotel
After getting off the ferry, exit the pier area and follow the main road heading inland. Don't turn into the narrow streets, stay on the main road. At the Gendarmerie junction the road forks. Take the Tuzburnu Road on the left and keep going. After about 100 metres the road makes a clear curve to the left, so follow it, then take the first right immediately after. After 200 metres you'll see Oikos Bozcaada on your right.
