Upper Mustang is the last forbidden kingdom of Nepal with lots of mystical and mythical things. To reach this land beyond mountains one requires at least one week of walking after mountain flight to Jomsom. This can be very treacherous as well as physically demanding. Therefore, Nepal Trekking Routes Treks & Expeditions has proposed helicopter tour in Nepal. Mustang Helicopter Tour starts from Kathmandu similar to Everest Helicopter Tour and Annapurna Helicopter Tour. The scenic beauty en-route to Upper Mustang is joy to behold.
