The Annapurna base camp trek is not accessible by road in any phase. In the event of an emergency, an air ambulance will be dispatched as long as the weather permits evacuation to either Pokhara or Kathmandu. After that, you'll be transferred to a hospital of worldwide standing for rehabilitation. If an emergency arises during the trek, Outfitter Nepal’s operating staff will be available 24 hours a day, seven days a week.
