Packing for a Salar de Uyuni and Bolivian desert tour requires preparation for strong temperature changes at high altitude. Bring layered clothing, including a warm jacket and thermal base layers, as days can be sunny while nights become extremely cold. Since heating may be limited in remote accommodation, extra warm clothing can make overnight stays much more comfortable. It is also useful to carry personal snacks and a few basic essentials, as options outside scheduled tour meals can be limited. A sleeping bag or liner and a reliable flashlight are valuable additions for multi-day trips through the Bolivian desert.
