Bolu Province

Bolu is a province in northwestern Turkey covered by dense forests, mountains, and lakes spread across a wide area. The provincial capital sits at the center and is surrounded by nine districts, including Mengen, which has culinary schools, and Kartalkaya, which features winter sports facilities in mountain terrain.

The region was known in ancient times as Claudiopolis and later called Bithynia until Seljuk Turks took control in the 13th century. These transitions between different rulers shaped how the region developed over time.

The Yildirim Beyazit Mosque in the provincial capital shapes religious life in the region. Local residents and visitors gather here to experience the Islamic architecture that reflects different periods of rebuilding and restoration.

Visitors should know the region offers different activities depending on the season: mountains are open for winter sports in colder months, while other seasons suit hiking and exploration of the forests. Planning ahead helps when visiting multiple districts in a single trip.

Lake Abant sits at high elevation and is fed by underground springs that keep its water clear at considerable depth. This natural feature makes the lake a notable landmark in the local landscape.
