Preparing for high-altitude trekking in Leh Ladakh is crucial for a safe and enjoyable experience. Firstly, acclimatize by spending a couple of days in Leh to adjust to the elevation. Stay hydrated and avoid overexertion during the initial days. Pack warm clothing in layers, including insulated jackets, thermals, gloves, and hats to combat the cold. Good trekking boots with ankle support are essential. Carry a sturdy backpack, water bottles, energy-rich snacks, a first aid kit, and essential medications. Use sunscreen, sunglasses, and lip balm to protect against strong UV rays. Engage a certified local guide, follow their instructions, and respect the environment. Mental preparation and physical fitness are key; practice cardio exercises to enhance lung capacity.
