I am an Indian national(my parents as well). My parents are planning to go to Kailas Manasarovar trip in 2019.

The travel plan is from Delhi to Kathmandu to Lhasa >> Manasarovar to Kailas & back.

The total duration of the trip is from 18-Aug to 30-Aug 2019.(tentative)

I would like to have proper travel cover for both of my parents valid for a longer period than the actual trip itinerary, which should cover all aspects including emergency evacuation by helicopter, hospitalization etc.

Please advise.
