I really want to do the huayhuash trek with my dad in Peru for Oct 2026. But I’m terrified about the altitude sickness. Do people his age do treks like this? We are experienced with and good at hiking (but never tried high altitude trekking). We will take days to acclimatize and do the recommended acclimatization hikes. Santa Cruz is my backup, but huayhuash just looks so stunning and I don’t want to regret not doing it. We are willing to train beforehand if there’s any way to make doing huayhuash doable. Any recommendations? Thanks!
