There are various types of insurance that may be relevant to trekking and mountaineering, including travel insurance, adventure sports insurance, and medical evacuation insurance. Travel insurance may cover cancellation, lost or stolen items, and medical expenses. Adventure insurance may provide coverage for accidents, injuries, and equipment damage that occurs in the field. Medical evacuation insurance may cover the cost of emergency transport to a hospital or medical facility. It is important to carefully review the terms and conditions of any insurance policy before purchasing it, as some policies may have exclusions or limitations on coverage for certain activities or destinations.
