The best time to visit Karlukovo is during the late spring (May to June) and early autumn (September to October) when the weather is pleasant for outdoor activities and exploring the natural beauty of the region.
During late spring, the landscape is lush and green, and the temperatures are mild, typically ranging from 15°C to 25°C. This period is ideal for hiking, caving, and exploring the Prohodna Cave, also known as God's Eyes Cave, which is a major draw. The Iskar Gorge is particularly scenic with blooming wildflowers, making it a great time for photography and nature walks.
Early autumn offers similarly comfortable temperatures, usually between 10°C and 20°C, with less chance of rain than the spring. The changing colours of the foliage along the Iskar River add a beautiful dimension to the scenery, superb for those who enjoy a more subdued and picturesque environment.
