Yedigoller (Seven Lakes) National Park

Yedigoller (Seven Lakes) National Park offers Turkey's most spectacular autumn transformation, as its seven pristine lakes brilliantly reflect the fiery orange and gold hues of the surrounding beech forests. Situated at an elevation of 900 meters, this 1,649-hectare park experiences its peak foliage two weeks earlier than lower-altitude national parks. The interconnected lakes, linked by 15 kilometers of clearly marked trails, provide a more varied hiking experience than the single-lake circuit found at Lake Abant. Autumn visitors are treated to a remarkable 90% canopy color change rate, significantly exceeding the 60% average for Turkish deciduous forests. Büyükgöl, the largest of the lakes, spans an impressive 110,000 square meters and offers trout fishing opportunities at prices 30% lower than commercial farms. Despite being the smallest national park on this list, Yedigoller's concentrated natural beauty truly outshines many larger parks during its October peak, attracting over 200,000 annual visitors specifically for its vibrant fall colors.
