Do we need an ice axe?
Its use in Aconcagua is subject to snow and ice conditions, so it's impossible to confirm in advance whether the climbers will need it or not. However, many mountaineers use them when they go on Route 360, and it's a must for the Polish Direct Route. Petzl Glacier is recommended.
It can pose a danger to mountaineers without proper experience, so the guide may prefer a good pair of boots with suitable crampons and poles to avoid using the ice axe. It's frequently left in the base camp.
