We require that all of our clients have an insurance plan in place that includes helicopter evacuation in the plan.  There are no roads in or out of the Everest Region and the only way out is by walking or helicopter.  Make sure you have a good policy in place if you have an accident or injury.  Unfortunately, there has been a lot of fraudulent behavior from helicopter companies over the years in Nepal.  They have been found to be scamming on insurance calms over the past decade in the Everest Region. This makes getting insurance and real rescues harder for everyone else.  We use Global Rescue for our Helicopter evacuation cover. They have doctors on the ground in Kathmandu and will quickly assess you over the phone if you really need evacuation from the region.
