Acclimatize in Cusco first
Spend at least 24–48 hours in Cusco before the hike to reduce risk of altitude sickness; take it slow on the trail and hydrate frequently.

Layer for wide temperature swings
Temperatures vary from below freezing at the summit to mild in the valley; pack warm, breathable layers and a windproof shell.
Good traction matters
Stony switchbacks can be slippery when wet—choose boots with solid tread and consider trekking poles for balance.
Sturdy hiking boots
Support and grip for steep, often rocky switchbacks to Humantay.
Insulating midlayer and wind shell
