Seven Lakes, Seven Colors: Fall into Yedigöller’s Forest Symphony
An intimate loop of mirror lakes, fall color and easy wilderness near Bolu
You arrive at the park gate before sunrise and the world already feels slowed down—mist hovering at knee height over mirror-still water, birches standing like pale sentinels. A pair of ducks slips across the nearest lake, their wake cutting a bright thread through reflected orange maples. Yedigöller National Park, literally “Seven Lakes,” is the kind of place that asks you to lower your voice and listen: to fallen leaves, to water lapping the shore, to a forest that keeps time in seasons.
Trail Wisdom
Start at dawn
Early morning light gives the best reflections and the quietest trails; aim to be on the main loop before 9 AM in high season.
Water and waterproofs
Bring 1.5–2 liters of water and a lightweight waterproof jacket—shoreline conditions are damp and weather can change quickly.
Respect camping zones
Use the official campsite and existing fire rings; illegal fires and dispersed camping damage fragile lakeside vegetation.
Use a polarizer for photos
A polarizing filter cuts glare from lake surfaces and deepens fall foliage color for stronger images.

Conservation Note
The park limits motorized access and concentrates camping in designated zones; visitors are asked to follow leave-no-trace principles to protect sensitive lake ecosystems.
Yedigöller was designated a national park in the mid-20th century to protect its unique cluster of landslide-formed lakes and surrounding mixed forests.
