Fly to Nepal’s capital Kathmandu where you will ideally need to spend a few days/nights before flying domestically west to Pokhara. We advise driving by SUV/4WD from Pokhara into the Mustang region, via the villages of Kalopani and Marpha. Lower Mustang is part of Nepal and Upper Mustang is still an autonomous region within Nepal. Flying from Pokhara to Jomson (v.v.) is an option but best to avoid the monsoon months of late May-early SEP.
