Many travel insurance policies specifically exclude mountaineering from coverage. This can either be defined by an elevation limit or the use of ropes and pick axes for the purpose of climbing. The following is the definition of mountaineering from Travelex. Always refer to the certificate of insurance for details.
“Mountaineering is the sport of walking, hiking, backpacking and climbing mountains which usually involves a mixture of ice climbing, rock climbing and mixed climbing where the climbers carry all their loads with them at all times. It generally requires the use of ropes, picks, axes, and other specialized equipment.”
