The best time to go to Kozi Rog is during the shoulder seasons, specifically late spring (May to early June) and early autumn (September to October).
During these periods, the weather is pleasantly mild, making it ideal for outdoor activities like hiking and exploring the surrounding nature reserves. You'll find fewer crowds compared to the peak summer months, allowing for a more relaxed experience. The countryside is particularly beautiful, with blooming wildflowers in spring and vibrant foliage in autumn.
Families with school-aged children might find the summer months (July and August) more convenient due to school holidays. While it can be warmer, the region's higher elevation often provides a welcome respite from the intense heat found in other parts of Bulgaria. There are also more family-orientated activities and events available during this peak season.
For those seeking a quieter, more reflective trip, the winter months (December to March) offer a unique appeal. The landscape is often covered in snow, creating a picturesque setting.
