It contains a mix of deciduous species including sessile oak, hornbeam, and flowering ash.
Alemdağ Ormanı is a large, rugged forest area situated on the Anatolian side of Istanbul, known for its dense oak and beech vegetation. It functions as a significant ecological corridor and natural lung for the rapidly developing Çekmeköy district. The terrain is characterized by hilly topography and unpaved, winding trails suitable for trekking and mountain biking. Unlike landscaped urban parks, this forest remains largely in its wild, natural state with minimal infrastructure. It serves as a popular regional destination for trail runners and hikers seeking escape from Istanbul’s urban density.
The elevated ridges overlooking the Ömerli Dam basin provide the widest vistas of the canopy.

Carry sufficient water and snacks, as there are no vendor kiosks or facilities inside the forest interior.
Attempting to drive deep into the forest trails with standard passenger vehicles; stay on the designated periphery roads.
