Acclimatize in Quito
Spend at least 24–48 hours in Quito before high treks to reduce altitude sickness risk; hydrate and avoid alcohol.
Layer for wide temperature swings
Temperatures can go from warm midday sun to sub‑freezing nights—use a breathable base, insulating mid layer and a waterproof shell.
Sturdy, broken‑in boots
Trails are rocky, wet and sometimes slippery; ankle support and good tread will make steep ascents safer.
Protect against strong UV
High altitude increases UV exposure—sunscreen, sunglasses and a wide‑brim hat are non‑negotiable.
High‑altitude trekking boots
Support and traction for rocky, uneven Andean trails.
Insulating down jacket

fall
3‑season sleeping bag (rated to −5°C/23°F)
