Yedigöller National Park
Journey into the Colorful World of Nature
Have you ever seen seven lakes connected to one another? Here is Yedigöller National Park, exactly such a place! Located 42 kilometers north of Bolu, amidst the emerald forests of Western Black Sea, the park takes its name from its seven side-by-side lakes. Protected as a national park since 1965, Yedigöller is an open-air treasure for nature lovers and curious explorers alike.

Where Are Yedigöller and How Were They Formed?
Yedigöller consists of seven lakes: Büyükgöl, Seringöl, Deringöl, Nazlıgöl, Küçükgöl, İncegöl and Sazlıgöl. These lakes were formed centuries ago when massive landslides blocked valleys, creating natural dams. The lakes are interconnected through surface and underground water flows, meaning water can pass from one lake to another.
Characteristics of the Lakes
Büyükgöl: The largest lake, reaching a depth of 15 meters. Turkey’s first trout breeding station was established here.
Nazlıgöl: Also known as the “Waterfall Lake” due to the cascade formed by water emerging from its bottom.
Seringöl, Deringöl, Küçükgöl, İncegöl and Sazlıgöl: Each has its own unique size and appearance.

Mammals: Bear, deer, roe deer, fox, badger, squirrel.
Birds: Wild duck, pigeon, woodpecker, partridge and hundreds of other species.

Accommodation and Access
You can stay in bungalows or set up a tent within the park. Access is possible by turning off the Ankara–Istanbul highway toward Bolu or Yeniçağa. However, during winter months the Bolu–Yedigöller road may be closed due to snow, so it is necessary to take the route via Yeniçağa–Mengen–Yazıcık.
