The Salar de Uyuni sits at around 3,600 meters above sea level, while some nearby deserts, lagoons, and volcanic areas are located at even higher elevations. At this altitude, travelers may experience shortness of breath, fatigue, headaches, or other symptoms of altitude sickness, particularly during the first days of a trip. Staying hydrated, taking things slowly, and allowing your body time to adjust can make the experience more comfortable. If symptoms become severe or worsen, seek medical assistance rather than continuing the itinerary.
