What Is High-Altitude Trekking?
High-altitude trekking means hiking at elevations usually above 2,500 meters. The air gets thinner, the weather changes fast, and your body needs extra time to adjust. Trails in Nepal, the Himalaya, the Andes, and the Alps often fall into this category.
Acclimatization
Your body needs time to adapt. Most routes build in rest days at around 3,000 to 4,000 meters. Use these days to hydrate well, walk short distances, and avoid overexertion.
Food and Hydration
Eat warm, simple meals. Soups, rice, lentils, and carbs are common. Drink plenty of water and avoid alcohol at high altitude.
