Gebze is located in the northwest part of Türkiye. It is in the Marmara Region. It sits on the northern coast of the Marmara Sea.
Gebze is in a fantastic location. It is very close to major cities:
To the West: Istanbul (Türkiye's biggest city)
To the East: Izmit (the center of Kocaeli)
To the South: The Gulf of Izmit and the Marmara Sea
To the North: Dilek peninsula and green nature areas
Because Gebze is right next to Istanbul, many people live in Gebze but travel to Istanbul for work or school every day.
