Seven Mirrors in the Forest: Hiking Turkey’s Yedigöller National Park
A compact loop of seven still lakes, ancient forests, and quiet elevation—no fluff, just the good stuff.
Mist rises off the water like a whispered secret as you round the edge of Büyük Göl, the largest of Yedigöller’s seven lakes. Beech leaves, still wet from the night, clap softly in a morning breeze that nudges the shore and dares you deeper into the forest. The trail, a damp ribbon of earth and roots, leads from one still, green mirror to the next—Sazlıgöl, İncegöl, Nazlıgöl, Seringöl, Deringöl, and Küçükgöl—each with its own mood, each reflecting the Black Sea sky like a story changing as you turn the page.
Trail Wisdom
Go Clockwise From Büyük Göl
Starting at the main lot and moving clockwise saves the Kapankaya viewpoint for later and keeps you with the gentler grades early.
Expect Mud After Rain
The beech forest holds moisture; waterproof footwear with solid tread will keep you upright on roots and leaf litter.
Beat Autumn Crowds Early
In October, arrive before 9 a.m. for parking and calm reflections on the lakes before wind and traffic ripple the water.
Carry Cash For Entry
Park entrance and camping fees are often easiest to pay in cash; card readers can be unreliable.

Helpful on slick leaf-covered descents and for stability around spillways.
Thermos With Hot Drink
Warmth on a cold ridge or lakeshore extends your comfort and encourages longer exploration.

Yes. Camping is allowed in designated areas near the lakes; facilities are basic, and fires may be restricted—check current rules at the gate.
Are the roads accessible year-round?
