The best time to visit the Balkan region in Haskovo Province, Bulgaria, is during the late spring (May to June) and early autumn (September to October).
These periods offer pleasant temperatures, generally ranging from 18°C to 25°C, making it comfortable for exploring the outdoors without the intense heat of summer. You'll find the countryside lush and green in spring, great for hiking and enjoying nature, while autumn brings beautiful colours to the landscapes and is ideal for wine tasting as the harvest season begins.
For those interested in outdoor activities like hiking and cycling, late spring is particularly good. The weather is usually settled, and the trails are in excellent condition. Families might also appreciate these times as the temperatures are agreeable for children to be outside, and there are often fewer crowds than in the peak summer months.
If your focus is on cultural events and experiencing local traditions, early autumn is often rich with festivals, particularly those celebrating the harvest.
