During the summer season, the Kocaeli Metropolitan Municipality implemented various seasonal transportation services to manage high public demand and facilitate tourism.

One initiative, the ‘Journey to Büyükada’ ferry service, provided Sunday day-trips from Kocaeli to the Istanbul island of Büyükada via the Marmara Sea. This service included stops at Değirmendere, Karamürsel, and Darıca.

Additionally, the 800CK bus line, operated by UlaşımPark A. Ş., provided seasonal access to coastal areas and Blue Flag beaches such as Kerpe, Miço Kadınlar Plajı, Kefken, and Cebeci. This bus route was intended to reduce traffic congestion in coastal regions and was scheduled to conclude its summer operations on September 13.
