While some parts of Upper Mustang are accessible by road, such as the journey from Jomsom to Lo Manthang, the road conditions can be rough, and the experience is not the same as trekking. The trek offers a much more immersive experience, allowing you to fully appreciate the region’s landscapes, culture, and remote villages. If you’re short on time or prefer not to trek, you can hire a jeep, but be prepared for a bumpy and dusty ride.
