Prioritize acclimatization
Use scheduled rest days—add an extra rest day if you feel any altitude symptoms; descend immediately for persistent breathing issues.
Footwear and traction
Sturdy, broken‑in mountaineering boots and gaiters reduce blisters and protect on scree and moraine; consider microspikes for icy sections.
Hydrate and snack often
Cold suppresses thirst—carry insulated water bottle or thermos and sip steady; pack energy-dense snacks for long pass days.
Plan for Lukla flight delays
Allow buffer days before/after the trek—morning flights to Lukla are common but weather can force cancellations.
Mountaineering boots
Support and insulation for prolonged walks on scree, moraine and icy approaches.
Insulated down jacket (800-fill or similar)
Critical for summit mornings and high‑pass exposure when temperatures plummet.
Trekking poles
Reduce knee strain on long descents and provide balance on loose rock and snow.
Microspikes or light crampons
Useful on icy trail sections or early/late season passes when snow and ice linger.
