Yes, traffic on the Karakoram Highway increases noticeably during peak summer season. June and July bring higher vehicle volume, especially on weekends.
Why Traffic Increases
The Karakoram Highway connects Islamabad to Gilgit-Baltistan and serves as the main road to Hunza and Skardu. During school holidays, many families travel north, leading to congestion in sections near Abbottabad, Besham, and Chilas.
Although the highway is generally wide and well-maintained in many stretches, mountain sections with narrow lanes and construction zones can slow traffic. Heavy vehicles and tourist coaches may also contribute to reduced speed.
When Congestion Is Highest
- Friday departures and Sunday returns
- Long public holidays
- Peak July travel weeks
Starting early in the morning and avoiding holiday weekends helps reduce delays. While congestion is manageable, travel times can extend beyond standard estimates during peak months.
