Having travel insurance is a must when you are traveling in Nepal. This will make it easier to cover theft, medicalassistance costs, as well as immediate rescue operations in case of an unexpected event while trekking in the mountains. There is a wide range of policies available, so make sure that your insurance policy includes coverage for medical and emergency evacuation, including helicopter evacuation for trekkers. For medical coverage, make sure that the policy pays to hospitals directly instead of you having to pay on the spot and claim later.
