Solo hiking or trekking through Ladakh and Zanskar without a guide is possible, but it’s not recommended. The region’s rugged terrain, high altitude, and remote areas can be challenging and potentially risky for inexperienced trekkers. A knowledgeable local guide can provide essential assistance, navigation, and knowledge of the terrain, as well as ensure safety during emergencies. They can also help with permits and cultural understanding. Additionally, traveling with a guide provides an opportunity to learn about the local culture, history, and unique aspects of the region. It’s advisable to prioritize safety and consider hiring a guide for a more enjoyable and secure trekking experience.
