Kocaeli, the third largest city in the Marmara Region, is home to many places that attract the attention of local and foreign tourists with its historical and natural beauties, although it stands out with its developed industry. Due to its proximity to two big cities such as Istanbul and Bursa, it is ideal for day trips and camps where you can spend the weekend in peace. Erikli Plateau and Sülüklü Lake are just two of the most frequently visited camping areas.
