Yedigöl

Yedigöl, also known as Yedigöller or the Seven Lakes, is a national park in Bolu Province in northwestern Turkey. It lies in the Western Black Sea region and sits in a forested valley that contains seven lakes of varying size, which gives the park its name. The lakes are connected by streams and are surrounded by a mosaic of coniferous and deciduous forests.

Geography and formation

The lakes were formed by natural processes in the valley, with basins created by landslides and damming along the hillside. Water levels fluctuate with seasonal rainfall, producing a scenic setting that changes throughout the year. The landscape combines rugged topography with dense woodland, creating a habitat for a variety of animal and plant life.

Flora and fauna

Yedigöl preserves mixed forests that include pine, fir and other conifers, along with deciduous trees such as beech. The understory supports shrubs and herbs typical of montane woodlands. Wildlife in the park includes red deer, roe deer, wild boar, foxes and wolves, as well as numerous bird species. The lakes host resident fish populations and attract amphibians and invertebrates, contributing to the park’s ecological richness.

Tourism and recreation

The park is a popular year-round destination, especially in autumn when the foliage colors are vivid. Visitors can follow marked trails and wooden boardwalks around the lakes to access viewpoints and picnic areas. Camping and certain activities are allowed only in designated zones, and motor vehicle access is restricted in sensitive zones to protect the environment.

Protection and management

Yedigöl is protected as a national park and is managed by Turkey’s national park authorities as part of the country’s network of protected areas dedicated to conserving natural ecosystems and promoting sustainable tourism.
